In both of these cases, telling the LLDD to abort the sas_task makes no sense because the LLDD won't know about the sas_task; what we really want to do is to increase the timer.

This can happen in two cases: (1) the scsi_cmnd actually made it through libsas to the HBA and is now going through scsi_done, or (2) the scsi_cmnd has been held up (host lock, slab alloc, etc) and libsas has not yet attached a sas_task. In both cases, it is safe to ask SCSI for more time to process the command via EH_RESET_TIMER; we cannot blindly return EH_HANDLED because if (2) happens, we could end up calling scsi_done while another CPU is heading towards sas_queuecommand, which causes slab corruption when sas_task_done updates the freed scsi_cmnd.

By deferring things to the EH we simplify the concurrency coordination and eliminate some race conditions. Note that sas_task_abort has a few hooks to handle libsas internal commands properly too. Also rename do_sas_task_abort to __sas_task_abort just in case we really want to abort the task *right now* and we don't have a scsi_cmnd attached to the command. This is a hook for libata internal commands to abort. Signed-off-by: Darrick J.

If so, the SAS addresses of the port and the phy are compared to determine if we need to detach from the port because the addresses don't match or if we can stop; the SAS address stored in the sas_port reflects whatever device _was_ attached to the port/phy, and the SAS address stored in the sas_port reflects whatever device we just discovered. As written, the code detaches from the port if the addresses _do_ match, and prints an error if they do _not_ match. I believe this to be incorrect, as it seems more logical to keep the port if the addresses match (i.e. the phy was reset but the device didn't change), and detach it they do not (i.e. the device changed).

Wong" Date: Fri, 26 Jan 2007 14:08:43 -0800 Subject: [PATCH 0055/1200] [SCSI] libsas: Clean up discovery failure handler code sas_rphy_delete does two things: it removes the sas_rphy from the transport layer and frees the sas_rphy. This can be broken down into two functions, sas_rphy_remove and sas_rphy_free; sas_rphy_remove is of interest to sas_discover_root_expander because it calls functions that require sas_rphy_add as a prerequisite and can fail (namely sas_discover_expander). In that case, sas_discover_root_expander needs to be able to undo the effects of sas_rphy_add yet leave the job of freeing the sas_rphy to the caller of sas_discover_root_expander. This patch also removes some unnecessary code from sas_discover_end_dev to eliminate an unnecessary cycle of sas_notify_lldd_gone/found for SAS devices, thus eliminating a sas_rphy_remove call (and fixing a race condition where a SCSI target scan can come in between the gone and found call). It also moves the sas_rphy_free calls into sas_discover_domain and sas_ex_discover_end_dev to complement the sas_rphy_allocation via sas_get_port_device. This patch does not change the semantics of sas_rphy_delete. Signed-off-by: Darrick J.

It also detects commands that have no sas_task (i.e. they completed, but with error data) and sends them into scsi_error for processing. This allows us to handle SCSI errors (and enables auto-spinup as a side effect) instead of dropping them on the floor and falling into an infinite loop. It also requires the implementation of a device reset function, which the SAS failure code has been modified to employ for REQ_DEVICE_RESET. Signed-off-by: Darrick J.

Current implementation does the target resets from delayed work tasks, that in heavy load conditions, take too long to be invoked, resulting in command time outs This patch will issue target reset immediately from ISR context, and will queue remaining target resets to be issued after the previous one completes. The delayed work tasks are spawned during the target reset completion.

Read does trigger it in my system. The bug is not associated with any specific HBA. st tries to do direct i/o in fixed block mode with reads that are not a multiple of tape block size. The patch in this message fixes the st problem by switching to using the driver buffer up to the next close of the device file in fixed block mode if the user asks for a read like this. I don't know why the bug has surfaced only after 2.6.17 although the st problem is old. There may be another bug in the block subsystem and this patch works around it. However, the patch fixes a problem in st and in this way it is a valid fix. This patch may also fix the bug 7900. The patch compiles and is lightly tested.

If it is the case that the phy being discovered happens to be the second phy of a wide link to an expander, that discover_dev function will incorrectly call sas_ex_discover_expander, which creates another sas_port and tries to attach the other sas_phys to the new port, thus triggering a BUG. The correct thing to do is to check the other ex_phys of the expander to see if there's a sas_port for this sas_phy, and attach the sas_phy to the existing sas_port. This is easily triggered if one enables the phys of a wide port between expanders one by one. This second version of the patch fixes a small regression in the case where all the phys show up at once and we accidentally try to attach to a port that hasn't been created yet.

This limit makes the csr scanning routine to never see the audio unit node , and consequently the iSight driver probe() routine to be never called and there is no way to hook an isight device when it is inserted.

While this is certainly a kernel bug, its not critical and crashing the kernel is too drastic, especially when considering that these errors have appeared multiple times in the past and it BUGs even if no listeners are present. This patch replaces BUG by WARN_ON and changes the notification functions to inform potential listeners of undersized allocations using a unique error code (EMSGSIZE).

The problem is that packets between different domains on the same Xen host only have partial checksums. Unfortunately this piece of information is not passed along in AF_PACKET unless you're using the mmap interface. Since dhcpd doesn't support packet-mmap, UDP packets from the same host come out with apparently bogus checksums. This patch adds a mechanism for AF_PACKET recvmsg(2) to return the status along with the packet. It does so by adding a new cmsg that contains this information along with some other relevant data such as the original packet length.

These timers all were of the "about once a second" or "about once every X seconds" variety and several showed up in the "what wakes the cpu up" profiles that the tickless patches provide. Some timers are highly dynamic based on network load; but even on low activity systems they still show up so the rounding is done only in cases of low activity, allowing higher frequency timers in the high activity case. The various hardware watchdogs are an obvious case; they run every 2 seconds but aren't otherwise specific of exactly when they need to run.

Useful if one needs to manipulate X.25 traffic with tools like tc. This is an update/cleanup based off a patch submitted by Daniel Ferenci a few years ago. Thanks Alan for the feedback. Added the null check to the clones. Moved the skb_clone's into the forwarding functions. Worked ok with Cisco XoT, linux X.25 back to back, and some old NTUs/PADs.

This is non optimal because of for a given hash or socket, the two chain heads are located in separate cache lines. Moreover the locks of the second half are never used. If instead of this halving, we use two list heads in inet_ehash_bucket instead of only one, we probably can avoid one cache miss, and reduce ram usage, particularly if sizeof(rwlock_t) is big (various CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_LOCK_ALLOC settings). So we still halves the table but we keep together related chains to speedup lookups and socket state change. In this patch I did not try to align struct inet_ehash_bucket, but a future patch could try to make this structure have a convenient size (a power of two or a multiple of L1_CACHE_SIZE). I guess rwlock will just vanish as soon as RCU is plugged into ehash :) , so maybe we dont need to scratch our heads to align the bucket... Note : In case struct inet_ehash_bucket is not a power of two, we could probably change alloc_large_system_hash() (in case it use __get_free_pages()) to free the unused space. It currently allocates a big zone, but the last quarter of it could be freed. Again, this should be a temporary 'problem'. Patch tested on ipv4 tcp only, but should be OK for IPV6 and DCCP.

db2a416556af0313db028147e4a22fef6f214f2f Mon Sep 17 00:00:00 2001 From: Frank Mandarino Date: Fri, 6 Oct 2006 18:31:09 +0200 Subject: [PATCH 0222/1200] [ALSA] ASoC: core code This patch is the core of ASoC functionality. The ASoC core is designed to provide the following features :- o Codec independence. Allows reuse of codec drivers on other platforms and machines. o Platform driver code reuse. Reuse of platform specific audio DMA and DAI drivers on different machines. o Easy I2S/PCM digital audio interface configuration between codec and SoC. Each SoC interface and codec registers their audio interface capabilities with the core at initialisation. The capabilities are subsequently matched and configured at run time for best power and performance when the application hw params are known. o Machine specific controls/operations: Allow machines to add controls and operations to the audio subsystem. e.g. volume control for speaker amp. To achieve all this, ASoC splits an embedded audio system into 3 components :- 1. Codec driver: The codec driver is platform independent and contains audio controls, audio interface capabilities, codec dapm and codec IO functions. 2. Platform driver: The platform driver contains the audio dma engine and audio interface drivers (e.g. I2S, AC97, PCM) for that platform. 3. Machine driver: The machine driver handles any machine specific controls and audio events. i.e. turning on an amp at start of playback.

Dynamic Audio Power Management (DAPM) is designed to allow portable and handheld Linux devices to use the minimum amount of power within the audio subsystem at all times. It is independent of other kernel PM and as such, can easily co-exist with the other PM systems. DAPM is also completely transparent to all user space applications as all power switching is done within the ASoC core. No code changes or recompiling are required for user space applications. DAPM makes power switching decisions based upon any audio stream (capture/playback) activity and audio mixer settings within the device. DAPM spans the whole machine. It covers power control within the entire audio subsystem, this includes internal codec power blocks and machine level power systems. There are 4 power domains within DAPM:- 1. Codec domain - VREF, VMID (core codec and audio power) Usually controlled at codec probe/remove and suspend/resume, although can be set at stream time if power is not needed for sidetone, etc. 2. Platform/Machine domain - physically connected inputs and outputs Is platform/machine and user action specific, is configured by the machine driver and responds to asynchronous events e.g when HP are inserted 3. Path domain - audio subsystem signal paths Automatically set when mixer and mux settings are changed by the user. e.g. alsamixer, amixer. 4. Stream domain - DAC's and ADC's. Enabled and disabled when stream playback/capture is started and stopped respectively. e.g. aplay, arecord. All DAPM power switching decisions are made automatically by consulting an audio routing map of the whole machine. This map is specific to each machine and consists of the interconnections between every audio component (including internal codec components).

It is +now also popular in many portable devices. This DAI has a reset line and time +multiplexes its data on its SDATA_OUT (playback) and SDATA_IN (capture) lines. +The bit clock (BCLK) is always driven by the CODEC (usually 12.288MHz) and the +frame (FRAME) (usually 48kHz) is always driven by the controller. Each AC97 +frame is 21uS long and is divided into 13 time slots. + +The AC97 specification can be found at http://intel.com/ + + +I2S +=== + + I2S is a common 4 wire DAI used in HiFi, STB and portable devices. The Tx and +Rx lines are used for audio transmision, whilst the bit clock (BCLK) and +left/right clock (LRC) synchronise the link. I2S is flexible in that either the +controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock +usually varies depending on the sample rate and the master system clock +(SYSCLK). LRCLK is the same as the sample rate. A few devices support separate +ADC and DAC LRCLK's, this allows for similtanious capture and playback at +different sample rates. + +I2S has several different operating modes:- + + o I2S - MSB is transmitted on the falling edge of the first BCLK after LRC + transition. + + o Left Justified - MSB is transmitted on transition of LRC. + + o Right Justified - MSB is transmitted sample size BCLK's before LRC + transition. + +PCM +=== + +PCM is another 4 wire interface, very similar to I2S, that can support a more +flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used +to synchronise the link whilst the Tx and Rx lines are used to transmit and +receive the audio data. Bit clock usually varies depending on sample rate +whilst sync runs at the sample rate. PCM also supports Time Division +Multiplexing (TDM) in that several devices can use the bus similtaniuosly (This +is sometimes referred to as network mode). + +Common PCM operating modes:- + + o Mode A - MSB is transmitted on falling edge of first BCLK after FRAME/SYNC. + + o Mode B - MSB is transmitted on rising edge of FRAME/SYNC. + + +ASoC DAI Configuration +====================== + +Every CODEC DAI and SoC DAI must have their capabilities defined in order to +be configured together at runtime when the audio and clocking parameters are +known. This is achieved by creating an array of struct snd_soc_hw_mode in the +the CODEC and SoC interface drivers.

Note: Audio clocking can be complex ! + + +Master Clock +------------ + +Every audio subsystem is driven by a master clock (sometimes refered to as MCLK +or SYSCLK). This audio master clock can be derived from a number of sources +(e.g. crystal, PLL, CPU clock) and is responsible for producing the correct +audio playback and capture sample rates. + +Some master clocks (e.g. PLL's and CPU based clocks) are configuarble in that +their speed can be altered by software (depending on the system use and to save +power). Other master clocks are fixed at at set frequency (i.e. crystals). + + +DAI Clocks +---------- +The Digital Audio Interface is usually driven by a Bit Clock (often referred to +as BCLK). This clock is used to drive the digital audio data across the link +between the codec and CPU. + +The DAI also has a frame clock to signal the start of each audio frame. This +clock is sometimes referred to as LRC (left right clock) or FRAME. This clock +runs at exactly the sample rate. + +Bit Clock is usually always a ratio of MCLK or a multiple of LRC. i.e. + +BCLK = MCLK / x + + or + +BCLK = LRC * x + +This relationship depends on the codec or SoC CPU in particular. ASoC can quite +easily match a codec that generates BCLK by division (FSBD) with a CPU that +generates BCLK by multiplication (FSB). + + +ASoC Clocking +------------- + +The ASoC core determines the clocking for each particular configuration at +runtime. This is to allow for dynamic audio clocking wereby the audio clock is +variable and depends on the system state or device usage scenario. i.e. a voice +call requires slower clocks (and hence less power) than MP3 playback. + +ASoC will call the config_sysclock() function for the target machine during the +audio parameters configuration. The function is responsible for then clocking +the machine audio subsytem and returning the audio clock speed to the core. +This function should also call the codec and cpu DAI clock_config() functions +to configure their respective internal clocking if required. + + +ASoC Clocking Control Flow +-------------------------- + +The ASoC core will call the machine drivers config_sysclock() when most of the +DAI capabilities are known. The machine driver is then responsible for calling +the codec and/or CPU DAI drivers with the selected capabilities and the current +MCLK. Note that the machine driver is also resonsible for setting the MCLK (and +enabling it). + + (1) Match Codec and CPU DAI capabilities. At this point we have + matched the majority of the DAI fields and now need to make sure this + mode is currently clockable. + + (2) machine->config_sysclk() is now called with the matched DAI FS, sample + rate and BCLK master. This function then gets/sets the current audio + clock (depening on usage) and calls the codec and CPUI DAI drivers with + the FS, rate, BCLK master and MCLK. + + (3) Codec/CPU DAI config_sysclock(). This function checks that the FS, rate, + BCLK master and MCLK are acceptable for the codec or CPU DAI.

DAPM makes power switching descisions based +upon any audio stream (capture/playback) activity and audio mixer settings +within the device. + +DAPM spans the whole machine. It covers power control within the entire audio +subsystem, this includes internal codec power blocks and machine level power +systems. + +There are 4 power domains within DAPM + + 1. Codec domain - VREF, VMID (core codec and audio power) + Usually controlled at codec probe/remove and suspend/resume, although + can be set at stream time if power is not needed for sidetone, etc. + + 2. Platform/Machine domain - physically connected inputs and outputs + Is platform/machine and user action specific, is configured by the + machine driver and responds to asynchronous events e.g when HP + are inserted + + 3. Path domain - audio susbsystem signal paths + Automatically set when mixer and mux settings are changed by the user. + e.g. alsamixer, amixer. + + 4. Stream domain - DAC's and ADC's. + Enabled and disabled when stream playback/capture is started and + stopped respectively. e.g. aplay, arecord. + +All DAPM power switching descisons are made automatically by consulting an audio +routing map of the whole machine. This map is specific to each machine and +consists of the interconnections between every audio component (including +internal codec components). All audio components that effect power are called +widgets hereafter. + + +2. DAPM Widgets +=============== + +Audio DAPM widgets fall into a number of types:- + + o Mixer - Mixes several analog signals into a single analog signal. + o Mux - An analog switch that outputs only 1 of it's inputs. + o PGA - A programmable gain amplifier or attenuation widget. + o ADC - Analog to Digital Converter + o DAC - Digital to Analog Converter + o Switch - An analog switch + o Input - A codec input pin + o Output - A codec output pin + o Headphone - Headphone (and optional Jack) + o Mic - Mic (and optional Jack) + o Line - Line Input/Output (and optional Jack) + o Speaker - Speaker + o Pre - Special PRE widget (exec before all others) + o Post - Special POST widget (exec after all others) + +(Widgets are defined in include/sound/soc-dapm.h) + +Widgets are usually added in the codec driver and the machine driver. There are +convience macros defined in soc-dapm.h that can be used to quickly build a +list of widgets of the codecs and machines DAPM widgets. + +Most widgets have a name, register, shift and invert. Some widgets have extra +parameters for stream name and kcontrols. + + +2.1 Stream Domain Widgets +------------------------- + +Stream Widgets relate to the stream power domain and only consist of ADC's +(analog to digital converters) and DAC's (digital to analog converters). + +Stream widgets have the following format:- + +SND_SOC_DAPM_DAC(name, stream name, reg, shift, invert), + +NOTE: the stream name must match the corresponding stream name in your codecs +snd_soc_codec_dai. + +e.g. stream widgets for HiFi playback and capture + +SND_SOC_DAPM_DAC("HiFi DAC", "HiFi Playback", REG, 3, 1), +SND_SOC_DAPM_ADC("HiFi ADC", "HiFi Capture", REG, 2, 1), + + +2.2 Path Domain Widgets +----------------------- + +Path domain widgets have a ability to control or effect the audio signal or +audio paths within the audio subsystem. They have the following form:- + +SND_SOC_DAPM_PGA(name, reg, shift, invert, controls, num_controls) + +Any widget kcontrols can be set using the controls and num_controls members. + +e.g. Mixer widget (the kcontrols are declared first) + +/* Output Mixer */ +static const snd_kcontrol_new_t wm8731_output_mixer_controls[] = { +SOC_DAPM_SINGLE("Line Bypass Switch", WM8731_APANA, 3, 1, 0), +SOC_DAPM_SINGLE("Mic Sidetone Switch", WM8731_APANA, 5, 1, 0), +SOC_DAPM_SINGLE("HiFi Playback Switch", WM8731_APANA, 4, 1, 0), +}; + +SND_SOC_DAPM_MIXER("Output Mixer", WM8731_PWR, 4, 1, wm8731_output_mixer_controls, + ARRAY_SIZE(wm8731_output_mixer_controls)), + + +2.3 Platform/Machine domain Widgets +----------------------------------- + +Machine widgets are different from codec widgets in that they don't have a +codec register bit associated with them. A machine widget is assigned to each +machine audio component (non codec) that can be independently powered. e.g. + + o Speaker Amp + o Microphone Bias + o Jack connectors + +A machine widget can have an optional call back. + +e.g. Jack connector widget for an external Mic that enables Mic Bias +when the Mic is inserted:- + +static int spitz_mic_bias(struct snd_soc_dapm_widget* w, int event) +{ + if(SND_SOC_DAPM_EVENT_ON(event)) + set_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS); + else + reset_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS); + + return 0; +} + +SND_SOC_DAPM_MIC("Mic Jack", spitz_mic_bias), + + +2.4 Codec Domain +---------------- + +The Codec power domain has no widgets and is handled by the codecs DAPM event +handler. This handler is called when the codec powerstate is changed wrt to any +stream event or by kernel PM events. + + +2.5 Virtual Widgets +------------------- + +Sometimes widgets exist in the codec or machine audio map that don't have any +corresponding register bit for power control. In this case it's necessary to +create a virtual widget - a widget with no control bits e.g. + +SND_SOC_DAPM_MIXER("AC97 Mixer", SND_SOC_DAPM_NOPM, 0, 0, NULL, 0), + +This can be used to merge to signal paths together in software. + +After all the widgets have been defined, they can then be added to the DAPM +subsystem individually with a call to snd_soc_dapm_new_control(). + + +3. Codec Widget Interconnections +================================ + +Widgets are connected to each other within the codec and machine by audio +paths (called interconnections). Each interconnection must be defined in order +to create a map of all audio paths between widgets. +This is easiest with a diagram of the codec (and schematic of the machine audio +system), as it requires joining widgets together via their audio signal paths. + +i.e. from the WM8731 codec's output mixer (wm8731.c) + +The WM8731 output mixer has 3 inputs (sources) + + 1. Line Bypass Input + 2. DAC (HiFi playback) + 3. Mic Sidetone Input + +Each input in this example has a kcontrol associated with it (defined in example +above) and is connected to the output mixer via it's kcontrol name. We can now +connect the destination widget (wrt audio signal) with it's source widgets. + + /* output mixer */ + {"Output Mixer", "Line Bypass Switch", "Line Input"}, + {"Output Mixer", "HiFi Playback Switch", "DAC"}, + {"Output Mixer", "Mic Sidetone Switch", "Mic Bias"}, + +So we have :- + + Destination Widget <=== Path Name <=== Source Widget + +Or:- + + Sink, Path, Source + +Or :- + + "Output Mixer" is connected to the "DAC" via the "HiFi Playback Switch". + +When there is no path name connecting widgets (e.g. a direct connection) we +pass NULL for the path name. + +Interconnections are created with a call to:- + +snd_soc_dapm_connect_input(codec, sink, path, source); + +Finally, snd_soc_dapm_new_widgets(codec) must be called after all widgets and +interconnections have been registered with the core. This causes the core to +scan the codec and machine so that the internal DAPM state matches the +physical state of the machine. + + +3.1 Machine Widget Interconnections +----------------------------------- +Machine widget interconnections are created in the same way as codec ones and +directly connect the codec pins to machine level widgets. + +e.g. connects the speaker out codec pins to the internal speaker. + + /* ext speaker connected to codec pins LOUT2, ROUT2 */ + {"Ext Spk", NULL , "ROUT2"}, + {"Ext Spk", NULL , "LOUT2"}, + +This allows the DAPM to power on and off pins that are connected (and in use) +and pins that are NC respectively. + + +4 Endpoint Widgets +=================== +An endpoint is a start or end point (widget) of an audio signal within the +machine and includes the codec. e.g. + + o Headphone Jack + o Internal Speaker + o Internal Mic + o Mic Jack + o Codec Pins + +When a codec pin is NC it can be marked as not used with a call to + +snd_soc_dapm_set_endpoint(codec, "Widget Name", 0); + +The last argument is 0 for inactive and 1 for active. This way the pin and its +input widget will never be powered up and consume power. + +This also applies to machine widgets. e.g. if a headphone is connected to a +jack then the jack can be marked active. If the headphone is removed, then +the headphone jack can be marked inactive. + + +5 DAPM Widget Events +==================== + +Some widgets can register their interest with the DAPM core in PM events. +e.g. A Speaker with an amplifier registers a widget so the amplifier can be +powered only when the spk is in use. + +/* turn speaker amplifier on/off depending on use */ +static int corgi_amp_event(struct snd_soc_dapm_widget *w, int event) +{ + if (SND_SOC_DAPM_EVENT_ON(event)) + set_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON); + else + reset_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON); + + return 0; +} + +/* corgi machine dapm widgets */ +static const struct snd_soc_dapm_widget wm8731_dapm_widgets = + SND_SOC_DAPM_SPK("Ext Spk", corgi_amp_event); + +Please see soc-dapm.h for all other widgets that support events. + + +5.1 Event types +--------------- + +The following event types are supported by event widgets. + +/* dapm event types */ +#define SND_SOC_DAPM_PRE_PMU 0x1 /* before widget power up */ +#define SND_SOC_DAPM_POST_PMU 0x2 /* after widget power up */ +#define SND_SOC_DAPM_PRE_PMD 0x4 /* before widget power down */ +#define SND_SOC_DAPM_POST_PMD 0x8 /* after widget power down */ +#define SND_SOC_DAPM_PRE_REG 0x10 /* before audio path setup */ +#define SND_SOC_DAPM_POST_REG 0x20 /* after audio path setup */ diff --git a/Documentation/sound/alsa/soc/machine.txt b/Documentation/sound/alsa/soc/machine.txt new file mode 100644 index 000000000000..3014795b1733 --- /dev/null +++ b/Documentation/sound/alsa/soc/machine.txt @@ -0,0 +1,114 @@ +ASoC Machine Driver +=================== + +The ASoC machine (or board) driver is the code that glues together the platform +and codec drivers. + +The machine driver can contain codec and platform specific code.

NForce and ICH4 (or newer) boards may be equipped with SPDIF through AC97 codec. In such a case, SPDIF should be handled as if the old ICH style (the same slot for analog and digital). A quirk list is added to detect this automatically for known hardwares. Corresponds to ALSA bug#2637.

Changes were required to support latest AT91 header files. Also updated to remove AT91RM9200-specific code in the ASoC platform drivers to support the AT91SAM9260 and AT91SAM9261 chips, but no testing was performed on these chips.

This is needed so the internal mono speaker (when present) can be controlled. This new control won't do anything in Acer laptops which are not fitted with a mono speaker. Acer models which are known to have a mono speaker are the C20x tablet series but there may be others. I guess we could define a new model specifically for Acers with mono speakers but this seems a bit silly given that such a model will be identical to the normal 'acer' model except for this added control. This patch also adds the C20x tablets to the list of PCI ids associated with the 'acer' model. This means that owners of C20x machines will no longer have to supply 'model=acer' when loading hda_intel.

From: Andrew Morton I converted the workqueues to per-device while I was there. It seems strange to create a new kernel thread (on each CPU!) and to then only have a single global work to ever be queued upon it. Plus without this, I'd have to use the _NAR stuff, gawd help me. Does that workqueue really need to be per-cpu? Does that workqueue really need to exist? Why not use keventd?

Since the alsa tests for the function by toggling the bit and reading it back to see if it changed, it mistakenly creates a useless control. This patch explicitly removes the control when the codec is an STAC9708/11. I put the check in patch_sigmatel_stac9708_specific(), because I have an SBLive with this chip on it. I don't know if the STAC9758 or other codecs also behave this way. If they do, then this check could maybe go in patch_sigmatel_stac97xx_specific(), or some other more general function.

The existing code can never utilize the shared jacks for Microphone and LINE_IN due to the reversed jack selection logic. The patched code correctly selects the shared jack for input if the 'Channel Mode' selector does not specify that the jack is to be used for output. Specifically, in '2ch' mode the Center/LFE jack is used for microphone input and the Surround jack is used for LINE_IN, in '4ch' mode the Center/LFE jack is used for microphone input and the Surround jack is used for output, and in '6ch' mode both jacks are used for output.

Previous patch 'AD1888 mixer controls for DC mode' added controls that were propogated to multiple codecs. For the AD1985 codec, the bits VREFH and VREFD function differently, preventing the 'V_REFOUT Enable' control from setting V_REFOUT to Hi-Z. This patch also corrects an issue in which register bits relating to mixer controls 'Surround Jack Mode' and 'Channel Mode'. The register bits controlled by these controls were being set at boot time to states inconsistent with the stored values of these controls.

This allowed the LINE_OUT and HEADPHONE jacks to function properly, however register differences between the CODECs prevented line and microphone inputs from functioning. Specifically, this patch fixes issues with the following mixer controls: 'V_REFOUT', 'Spread Front to Surround and Center/LFE', 'Exchange Front/Surround', 'Surround Jack Mode', and 'Channel Mode'. This patch removes the undocumented AD1888 control 'High Pass Filter Enable' and adds the new control 'Exchange Mic/Line In'.

Delayed work would be created (after audio had finished) with a long delay (~5 secs) and was sometimes never queued before flush_scheduled_work() was being called at suspend or module remove. This caused the delayed work to queued after the module had been removed or after resume. This patch forces any delayed work to complete by cancelling it (timer cannot fire and add it to queue later), scheduling it for now and waiting on it's completion.

Changes:- o Removed DAI capabilities matching code in favour of manual matching in the machine drivers. o Added DAI operations for codec and CPU interfaces. o Removed config_sysclk() function and struct snd_soc_clock_info. No longer needed as clocking is now configured manually in the machine drivers. Also removed other clocking data from structures.

Changes:- o Removed DAI capabilities matching code in favour of manual matching in the machine drivers. o Added DAI operations for codec and CPU interfaces. o Removed config_sysclk() function and struct snd_soc_clock_info. No longer needed as clocking is now configured manually in the machine drivers. Also removed other clocking data from structures.

ASoC 0.13 WM9712 codec driver This patch updates the WM9712 codec driver to the new API in ASoC 0.13. Changes:- o Removed DAI capabilities matching code in favour of manual matching in the machine drivers. o Added DAI operations for codec and CPU interfaces. o Removed config_sysclk() function and struct snd_soc_clock_info. No longer needed as clocking is now configured manually in the machine drivers. Also removed other clocking data from structures.

Changes:- o Removed DAI capabilities matching code in favour of manual matching in the machine drivers. o Added DAI operations for codec and CPU interfaces. o Removed config_sysclk() function and struct snd_soc_clock_info. No longer needed as clocking is now configured manually in the machine drivers. Also removed other clocking data from structures.

Changes were made in 'usbaudio.c', 'usbaudio.h', and 'usbquirks.h' MIDI and recording seem to work perfectly (with JACK), but playback gives some few glitches. I think that's the mentioned synchronizing-problem in the UA-1000 quirk ('FIXME: playback must be synchronized to capture'), so I didn't change that. ToDo: Adding Mixer-Support for the built-in control-panel/patch-bay/router.

It turns out that we can't just abort the DMA; we have to let it stop at the end of a command, and then wait for the S7 bit to be set before turning off the DBDMA controller. Doing that for playback doesn't seem to be necessary, but doesn't hurt either. We use the technique used by the Darwin driver: make each transfer command branch to a stop command if the S0 status bit is set. Thus we can ask the DMA controller to stop at the end of the current command by setting S0. The interrupt routine now looks at and clears the status word of the DBDMA command ring. This is necessary so it can know when the DBDMA controller has seen that S0 is set, and so when it should look for the DBDMA controller being stopped and S7 being set. This also ended up simplifying the calculation in i2sbus_pcm_pointer. Tested on a 15 inch albook. [Addition by Johannes] I modified this patch and added the suspend/resume bits to it to get my powermac into a decent state when playing sound across suspend to disk that has a different bitrate from what the firmware programs the hardware to. I also added the SNDRV_PCM_INFO_JOINT_DUPLEX flag because it seemed the right thing to do and I was looking at the info stuff.

Rozycki" Date: Mon, 5 Feb 2007 16:28:27 -0800 Subject: [PATCH 0438/1200] [TC] defxx: TURBOchannel support This is a set of changes to add TURBOchannel support to the defxx driver. As at this point the EISA support in the driver has become the only not having been converted to the driver model, I took the opportunity to convert it as well. Plus support for MMIO in addition to PIO operation as TURBOchannel requires it anyway. Signed-off-by: Maciej W.

This appears to have worked right until 2.6.11, when a fix to the default mode on symlinks (always 0777) assumed VFS applies umask: which it does, unless the mount is marked for ACLs; but ext[234] set MS_POSIXACL in s_flags according to s_mount_opt set according to def_mount_opts. We could revert to the 2.6.10 ext[234]_init_acl (adding an S_ISLNK test); but other filesystems only set MS_POSIXACL when ACLs are configured. We could fix this at another level; but it seems most robust to avoid setting the s_mount_opt flag in the first place (at the expense of more ifdefs). Likewise don't set the XATTR_USER flag when built without XATTR support.

J. Day" Date: Sat, 10 Feb 2007 01:46:20 -0800 Subject: [PATCH 0891/1200] [PATCH] extend the set of "__attribute__" shortcut macros Extend the set of "__attribute__" shortcut macros, and remove identical (and now superfluous) definitions from a couple of source files. based on a page at robert love's blog: http://rlove.org/log/2005102601 extend the set of shortcut macros defined in compiler-gcc.h with the following: #define __packed __attribute__((packed)) #define __weak __attribute__((weak)) #define __naked __attribute__((naked)) #define __noreturn __attribute__((noreturn)) #define __pure __attribute__((pure)) #define __aligned(x) __attribute__((aligned(x))) #define __printf(a,b) __attribute__((format(printf,a,b))) Once these are in place, it's up to subsystem maintainers to decide if they want to take advantage of them. there is already a strong precedent for using shortcuts like this in the source tree. The ones that might give people pause are "__aligned" and "__printf", but shortcuts for both of those are already in use, and in some ways very confusingly. note the two very different definitions for a macro named "ALIGNED": drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf)) drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x))) also: include/acpi/platform/acgcc.h: #define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1))) Given the precedent, then, it seems logical to at least standardize on a consistent set of these macros.

This differs from radix trees (which +are used to efficiently store sparse arrays and thus use long integer indexes +to insert/access/delete nodes) and hash tables (which are not kept sorted to +be easily traversed in order, and must be tuned for a specific size and +hash function where rbtrees scale gracefully storing arbitrary keys). + +Red-black trees are similar to AVL trees, but provide faster real-time bounded +worst case performance for insertion and deletion (at most two rotations and +three rotations, respectively, to balance the tree), with slightly slower +(but still O(log n)) lookup time. + +To quote Linux Weekly News: + + There are a number of red-black trees in use in the kernel. + The anticipatory, deadline, and CFQ I/O schedulers all employ + rbtrees to track requests; the packet CD/DVD driver does the same. + The high-resolution timer code uses an rbtree to organize outstanding + timer requests. The ext3 filesystem tracks directory entries in a + red-black tree. Virtual memory areas (VMAs) are tracked with red-black + trees, as are epoll file descriptors, cryptographic keys, and network + packets in the "hierarchical token bucket" scheduler. + +This document covers use of the Linux rbtree implementation. For more +information on the nature and implementation of Red Black Trees, see: + + Linux Weekly News article on red-black trees + http://lwn.net/Articles/184495/ + + Wikipedia entry on red-black trees + http://en.wikipedia.org/wiki/Red-black_tree + +Linux implementation of red-black trees +--------------------------------------- + +Linux's rbtree implementation lives in the file "lib/rbtree.c". To use it, +"#include ". + +The Linux rbtree implementation is optimized for speed, and thus has one +less layer of indirection (and better cache locality) than more traditional +tree implementations. Instead of using pointers to separate rb_node and data +structures, each instance of struct rb_node is embedded in the data structure +it organizes. And instead of using a comparison callback function pointer, +users are expected to write their own tree search and insert functions +which call the provided rbtree functions. Locking is also left up to the +user of the rbtree code. + +Creating a new rbtree +--------------------- + +Data nodes in an rbtree tree are structures containing a struct rb_node member: + + struct mytype { + struct rb_node node; + char *keystring; + }; + +When dealing with a pointer to the embedded struct rb_node, the containing data +structure may be accessed with the standard container_of() macro. In addition, +individual members may be accessed directly via rb_entry(node, type, member). + +At the root of each rbtree is an rb_root structure, which is initialized to be +empty via: + + struct rb_root mytree = RB_ROOT; + +Searching for a value in an rbtree +---------------------------------- + +Writing a search function for your tree is fairly straightforward: start at the +root, compare each value, and follow the left or right branch as necessary. + +Example: + + struct mytype *my_search(struct rb_root *root, char *string) + { + struct rb_node *node = root->rb_node; + + while (node) { + struct mytype *data = container_of(node, struct mytype, node); + int result; + + result = strcmp(string, data->keystring); + + if (result < 0) + node = node->rb_left; + else if (result > 0) + node = node->rb_right; + else + return data; + } + return NULL; + } + +Inserting data into an rbtree +----------------------------- + +Inserting data in the tree involves first searching for the place to insert the +new node, then inserting the node and rebalancing ("recoloring") the tree. + +The search for insertion differs from the previous search by finding the +location of the pointer on which to graft the new node. The new node also +needs a link to its parent node for rebalancing purposes. + +Example: + + int my_insert(struct rb_root *root, struct mytype *data) + { + struct rb_node **new = &(root->rb_node), *parent = NULL; + + /* Figure out where to put new node */ + while (*new) { + struct mytype *this = container_of(*new, struct mytype, node); + int result = strcmp(data->keystring, this->keystring); + + parent = *new; + if (result < 0) + new = &((*new)->rb_left); + else if (result > 0) + new = &((*new)->rb_right); + else + return FALSE; + } + + /* Add new node and rebalance tree. */ + rb_link_node(data->node, parent, new); + rb_insert_color(data->node, root); + + return TRUE; + } + +Removing or replacing existing data in an rbtree +------------------------------------------------ + +To remove an existing node from a tree, call: + + void rb_erase(struct rb_node *victim, struct rb_root *tree); + +Example: + + struct mytype *data = mysearch(mytree, "walrus"); + + if (data) { + rb_erase(data->node, mytree); + myfree(data); + } + +To replace an existing node in a tree with a new one with the same key, call: + + void rb_replace_node(struct rb_node *old, struct rb_node *new, + struct rb_root *tree); + +Replacing a node this way does not re-sort the tree: If the new node doesn't +have the same key as the old node, the rbtree will probably become corrupted. + +Iterating through the elements stored in an rbtree (in sort order) +------------------------------------------------------------------ + +Four functions are provided for iterating through an rbtree's contents in +sorted order. These work on arbitrary trees, and should not need to be +modified or wrapped (except for locking purposes): + + struct rb_node *rb_first(struct rb_root *tree); + struct rb_node *rb_last(struct rb_root *tree); + struct rb_node *rb_next(struct rb_node *node); + struct rb_node *rb_prev(struct rb_node *node); + +To start iterating, call rb_first() or rb_last() with a pointer to the root +of the tree, which will return a pointer to the node structure contained in +the first or last element in the tree. To continue, fetch the next or previous +node by calling rb_next() or rb_prev() on the current node. This will return +NULL when there are no more nodes left. + +The iterator functions return a pointer to the embedded struct rb_node, from +which the containing data structure may be accessed with the container_of() +macro, and individual members may be accessed directly via +rb_entry(node, type, member). + +Example: + + struct rb_node *node; + for (node = rb_first(&mytree); node; node = rb_next(node)) + printk("key=%s\n", rb_entry(node, int, keystring)); + From 72ed3d035855841ad611ee48b20909e9619d4a79 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Sat, 10 Feb 2007 01:46:22 -0800 Subject: [PATCH 0893/1200] [PATCH] buffer: memorder fix unlock_buffer(), like unlock_page(), must not clear the lock without ensuring that the critical section is closed. Mingming later sent the same patch, saying: We are running SDET benchmark and saw double free issue for ext3 extended attributes block, which complains the same xattr block already being freed (in ext3_xattr_release_block()). The problem could also been triggered by multiple threads loop untar/rm a kernel tree. The race is caused by missing a memory barrier at unlock_buffer() before the lock bit being cleared, resulting in possible concurrent h_refcounter update. That causes a reference counter leak, then later leads to the double free that we have seen. Inside unlock_buffer(), there is a memory barrier is placed *after* the lock bit is being cleared, however, there is no memory barrier *before* the bit is cleared. On some arch the h_refcount update instruction and the clear bit instruction could be reordered, thus leave the critical section re-entered. The race is like this: For example, if the h_refcount is initialized as 1, cpu 0: cpu1 -------------------------------------- ----------------------------------- lock_buffer() /* test_and_set_bit */ clear_buffer_locked(bh); lock_buffer() /* test_and_set_bit */ h_refcount = h_refcount+1; /* = 2*/ h_refcount = h_refcount + 1; /*= 2 */ clear_buffer_locked(bh); .... ...... We lost a h_refcount here. We need a memory barrier before the buffer head lock bit being cleared to force the order of the two writes. Please apply.

Fix enumeration in configurations with multiple switches. The patch adds: a. Enumeration of an empty switch. Empty switch is a switch that does not have any endpoint devices attached to it (except host device or previous switch in a chain). New code assigns a phony destination ID associated with the switch and sets up corresponding routes. b. Adds a second pass to the enumeration to setup routes to devices discovered after switch was scanned. 2. Fix enumeration failure when riohdid parameter has non-zero value. Current version fails to setup response path to the host when it has destination ID other that 0.

I wondered what else from io.h do we not need. The answer is: almost nothing. With the devres patch from Al and the dma-mapping patch from Heiko we can get rid of iomem and all associated definitions." So we'll just need to replace NO_IOPORT with NO_IOMEM in Kconfig and kill arch/s390/mm/ioremap.c. BTW, there's an annoying bit of junk in there - IO_SPACE_LIMIT. We only need it for /proc/ioports, which AFAICS shouldn't even be there on s390 (or uml). OTOH, removing that thing would mean a user-visible change - we go from "empty file in /proc" to "no such file in /proc"...

The current ccw_device_set_options() sets a specified mask of options and clears those not specified, but there is no way to find out which options have already been set. In order to fix this up, introduce the following interface changes: ccw_device_set_options() now only sets the specified bits, but does not clear those that are not specified. ccw_device_clear_options() clears the specified bits. ccw_device_set_options_mask() provides the old semantics (setting only the specified bits and clearing the others). Device drivers now work as expected. qdio has been adapted.

Recently, I found the long standing mmap/unwritten extent conversion bug, and it was to do with partial page invalidation not clearing the unwritten flag from bufferheads attached to the page but beyond EOF. See here for a full explaination: http://oss.sgi.com/archives/xfs/2006-12/msg00196.html The solution I have checked into the XFS dev tree involves duplicating code from block_invalidatepage to clear the unwritten flag from the bufferhead(s), and then calling block_invalidatepage() to do the rest. Christoph suggested that this would be better solved by pushing the unwritten flag into the common buffer head flags and just adding the call to discard_buffer(): http://oss.sgi.com/archives/xfs/2006-12/msg00239.html The following patch makes BH_Unwritten a first class citizen.

First, when d_path() hits a lazily unmounted mount point, it tries to prepend the name of the lazily unmounted dentry to the path name. It gets this wrong, and also overwrites the slash that separates the name from the following pathname component. This is demonstrated by the attached test case, which prints "getcwd returned d_path-bugsubdir" with the bug. The correct result would be "getcwd returned d_path-bug/subdir". It could be argued that the name of the root dentry should not be part of the result of d_path in the first place. On the other hand, what the unconnected namespace was once reachable as may provide some useful hints to users, and so that seems okay. Second, it isn't always possible to tell from the __d_path result whether the specified root and rootmnt (i.e., the chroot) was reached: lazy unmounts of bind mounts will produce a path that does start with a non-slash so we can tell from that, but other lazy unmounts will produce a path that starts with a slash, just like "ordinary" paths. The attached patch cleans up __d_path() to fix the bug with overlapping pathname components. It also adds a @fail_deleted argument, which allows to get rid of some of the mess in sys_getcwd(). Grabbing the dcache_lock can then also be moved into __d_path(). The patch also makes sure that paths will only start with a slash for paths which are connected to the root and rootmnt. The @fail_deleted argument could be added to d_path() as well: this would allow callers to recognize deleted files, without having to resort to the ambiguous check for the " (deleted)" string at the end of the pathnames. This is not currently done, but it might be worthwhile.

This driver has been used in the Linux-OMAP tree for some time now, including with some of those displays using standardized 9-bit commands followed by data with 8-bit words. Microwire only supports half duplex transfers, but that's all that most SPI protocols need. When full duplex, or higher speeds, are needed there are several other controllers that can be used on OMAP.

Main features summary: > Per chip setup via board specific code and/or protocol driver. > Per transfer setup. > PIO transfers. > DMA transfers. > Managing of NULL tx / rx buffer for rd only / wr only transfers. This patch replace patch-2.6.20-rc4-spi_imx with the following changes: > Few cosmetic changes. > Function map_dma_buffers now return 0 for success and -1 for failure. > Solved a bug inside spi_imx_probe function (wrong error path). > Solved a bug inside setup function (bad undo setup for max_speed_hz). > For read-only transfers, always write zero bytes. This is almost the same as the 'BIS' version sent by Andrea, except for updating the 'DUMMY' byte so that read-only transfers shift out zeroes. That part of the API changed recently, since some half duplex peripheral chips require that semantic.

Otherwise, if all options in the transfers are default (0), the overrided function will never be called. Granted, the function replacing it must call spi_bitbang_setup_transfer, but it might also have other important things to do, even if the second argument (the spi_transfer) is NULL. Tested together with the other patches on the spi_crisv32_sser and spi_crisv32_gpio drivers (not yet in the kernel, will IIUC be submitted as part of the usual arch-maintainer-pushes).

I can't do that without ugly casting (see the PXA patch) when the structure pointed to is const-qualified. I don't really see a reason why the cleanup method isn't allowed to alter the object it should clean up. :-) No, I didn't test the PXA patch, but I verified that the NULL-assignment doesn't stop me from doing rmmod/insmodding my own spi_bitbang-based driver.

(That time may already have passed, since nothing currently enforces one-shot alarm semantics.) - It can be written with an alarm time in the future, again seconds since the POSIX epoch, which enables the alarm. - It can be written with an alarm time not in the future (such as 0, the start of the POSIX epoch) to disable the alarm. Usage examples (some need GNU date) after "cd /sys/class/rtc/rtcN": alarm after 10 minutes: # echo $(( $(cat since_epoch) + 10 * 60 )) > wakealarm alarm tuesday evening 10pm: # date -d '10pm tuesday' "+%s" > wakealarm disable alarm: # echo 0 > wakealarm This resembles the /proc/acpi/alarm file in that nothing happens when the alarm triggers ... except possibly waking the system from sleep. It's also like that in a nasty way: not much can be done to prevent one task from clobbering another task's alarm settings. It differs from that file in that there's no in-kernel date parser. Note that a few RTCs ignore rtc_wkalrm.enabled when setting alarms, or aren't set up correctly, so they won't yet behave with this attribute.

Fortunately, google told me that Daniel Aragones had already done the work, patch found at http://www.terra.es/personal2/danarag/ Unfortunaly, looking at the patch was painful to my eyes, so I polished it a bit before applying. The resulting kernel boots, and reads the filesystem it needed to read.

Biederman" Date: Mon, 12 Feb 2007 00:52:51 -0800 Subject: [PATCH 0999/1200] [PATCH] tty: make __proc_set_tty static The aim of this patch set is to start wrapping up the struct pid conversions. As such this patchset culminates with the removal of kill_pg, kill_pg_info, __kill_pg_info, do_each_task_pid, and while_each_task_pid. kill_proc, daemonize, and kernel_thread are still in my sights but there is still work to get to them. The first three are basic cleanups around disassociate_ctty, while working on converting it I found several issues. tty_old_pgrp can be a tricky concept to wrap your head around. 1 tty: Make __proc_set_tty static. 2 tty: Clarify disassociate_ctty 3 tty: Fix the locking for signal->session in disassociate_ctty These just stop using the old helper functions. 4 signal: Use kill_pgrp not kill_pg in the sunos compatibility code. 5 signal: Rewrite kill_something_info so it uses newer helpers. Then the grind to convert the tty layer and all of it's helper functions to struct pid. 6 pid: Make session_of_pgrp use struct pid instead of pid_t. 7 pid: Use struct pid for talking about process groups in exit.c 8 pid: Replace is_orphaned_pgrp with is_current_pgrp_orphaned 9 tty: Update the tty layer to work with struct pid. A final helper function update. 10 pid: Replace do/while_each_task_pid with do/while_each_pid_task And the removal of the functions that are now unused. 11 pid: Remove now unused do_each_task_pid and while_each_task_pid 12 pid: Remove the now unused kill_pg kill_pg_info and __kill_pg_info All of these should be fairly simple and to the point. This patch: Currently all users of __proc_set_tty are in tty_io.c so make the function static. Signed-off-by: Eric W.

To this end session_of_pgrp is transformed to take and return a struct pid pointer. To avoid the need to worry about reference counting I now require my caller to hold the appropriate locks. Leaving callers repsonsible for increasing the reference count if they need access to the result outside of the locks. Since session_of_pgrp currently only has one caller and that caller simply uses only test the result for equality with another process group, the locking change means I don't actually have to acquire the tasklist_lock at all. tiocspgrp is also modified to take and release the lock. The logic there is a little more complicated but nothing I won't need when I convert pgrp of a tty to a struct pid pointer. Signed-off-by: Eric W.

So using struct pid winds up being a simple optimization to avoid hash table lookups.

This patch modifies the EDAC Core to provide the Interface for memory controller modules to implment. The following things are still outstanding: - K8 is the first implemenation, The patch provide a method of configuring the K8 hardware memory scrubber via the 'mcX' sysfs directory. There should be some fallback to a generic scrubber implemented in software if the hardware does not support scrubbing. Or .. the scrubbing sysfs entry should not be visible at all. - Only works with SDRAM, not cache, The K8 can scrub cache and l2cache also - but I think this is not so useful as the cache is busy all the time (one hopes). One would also expect that cache scrubbing requires hardware support. - Error Handling, I would like that errors are returned to the user in "terms of file system". - Presentation, I chose Bandwidth in Bytes/Second as a representation of the scrubbing rate for the following reasons: I like that the sysfs entries are sort-of textual, related to something that makes sense instead of magical values that must be looked up. "My People" wants "% main memory scrubbed per hour" others prefer "% memory bandwidth used" as representation, "bandwith used" makes it easy to calculate both versions in one-liner scripts. If one later wants to scrub cache, the scaling becomes wierd for K8 changing from "blocks of 64 byte memory" to "blocks of 64 cache lines" to "blocks of 64 bit". Using "bandwidth used" makes sense in all three cases, (I.M.O. anyway ;-). - Discovery, There is no way to discover the possible settings and what they do without reading the code and the documentation. *I* do not know how to make that work in a practical way. - Bugs(??), other tools can set invalid values in the memory scrub control register, those will read back as '-1', requiring the user to reset the scrub rate. This is how *I* think it should be. - Afflicting other areas of code, I made changes to edac_mc.c and edac_mc.h which will show up globally - this is not nice, it would be better that the memory scrubbing fuctionality and interface could be entirely contained within the memory controller it applies to.

They are provided from many kinds of chip, and are familiar +to Linux developers working with embedded and custom hardware. Each GPIO +represents a bit connected to a particular pin, or "ball" on Ball Grid Array +(BGA) packages. Board schematics show which external hardware connects to +which GPIOs. Drivers can be written generically, so that board setup code +passes such pin configuration data to drivers. + +System-on-Chip (SOC) processors heavily rely on GPIOs. In some cases, every +non-dedicated pin can be configured as a GPIO; and most chips have at least +several dozen of them. Programmable logic devices (like FPGAs) can easily +provide GPIOs; multifunction chips like power managers, and audio codecs +often have a few such pins to help with pin scarcity on SOCs; and there are +also "GPIO Expander" chips that connect using the I2C or SPI serial busses. +Most PC southbridges have a few dozen GPIO-capable pins (with only the BIOS +firmware knowing how they're used). + +The exact capabilities of GPIOs vary between systems. Common options: + + - Output values are writable (high=1, low=0). Some chips also have + options about how that value is driven, so that for example only one + value might be driven ... supporting "wire-OR" and similar schemes + for the other value. + + - Input values are likewise readable (1, 0). Some chips support readback + of pins configured as "output", which is very useful in such "wire-OR" + cases (to support bidirectional signaling). GPIO controllers may have + input de-glitch logic, sometimes with software controls. + + - Inputs can often be used as IRQ signals, often edge triggered but + sometimes level triggered. Such IRQs may be configurable as system + wakeup events, to wake the system from a low power state. + + - Usually a GPIO will be configurable as either input or output, as needed + by different product boards; single direction ones exist too. + + - Most GPIOs can be accessed while holding spinlocks, but those accessed + through a serial bus normally can't. Some systems support both types. + +On a given board each GPIO is used for one specific purpose like monitoring +MMC/SD card insertion/removal, detecting card writeprotect status, driving +a LED, configuring a transceiver, bitbanging a serial bus, poking a hardware +watchdog, sensing a switch, and so on. + + +GPIO conventions +================ +Note that this is called a "convention" because you don't need to do it this +way, and it's no crime if you don't. There **are** cases where portability +is not the main issue; GPIOs are often used for the kind of board-specific +glue logic that may even change between board revisions, and can't ever be +used on a board that's wired differently. Only least-common-denominator +functionality can be very portable. Other features are platform-specific, +and that can be critical for glue logic. + +Plus, this doesn't define an implementation framework, just an interface. +One platform might implement it as simple inline functions accessing chip +registers; another might implement it by delegating through abstractions +used for several very different kinds of GPIO controller. + +That said, if the convention is supported on their platform, drivers should +use it when possible: + + #include + +If you stick to this convention then it'll be easier for other developers to +see what your code is doing, and help maintain it. + + +Identifying GPIOs +----------------- +GPIOs are identified by unsigned integers in the range 0..MAX_INT. That +reserves "negative" numbers for other purposes like marking signals as +"not available on this board", or indicating faults. + +Platforms define how they use those integers, and usually #define symbols +for the GPIO lines so that board-specific setup code directly corresponds +to the relevant schematics. In contrast, drivers should only use GPIO +numbers passed to them from that setup code, using platform_data to hold +board-specific pin configuration data (along with other board specific +data they need). That avoids portability problems. + +So for example one platform uses numbers 32-159 for GPIOs; while another +uses numbers 0..63 with one set of GPIO controllers, 64-79 with another +type of GPIO controller, and on one particular board 80-95 with an FPGA. +The numbers need not be contiguous; either of those platforms could also +use numbers 2000-2063 to identify GPIOs in a bank of I2C GPIO expanders. + +Whether a platform supports multiple GPIO controllers is currently a +platform-specific implementation issue. + + +Using GPIOs +----------- +One of the first things to do with a GPIO, often in board setup code when +setting up a platform_device using the GPIO, is mark its direction: + + /* set as input or output, returning 0 or negative errno */ + int gpio_direction_input(unsigned gpio); + int gpio_direction_output(unsigned gpio); + +The return value is zero for success, else a negative errno. It should +be checked, since the get/set calls don't have error returns and since +misconfiguration is possible. (These calls could sleep.) + +Setting the direction can fail if the GPIO number is invalid, or when +that particular GPIO can't be used in that mode. It's generally a bad +idea to rely on boot firmware to have set the direction correctly, since +it probably wasn't validated to do more than boot Linux. (Similarly, +that board setup code probably needs to multiplex that pin as a GPIO, +and configure pullups/pulldowns appropriately.) + + +Spinlock-Safe GPIO access +------------------------- +Most GPIO controllers can be accessed with memory read/write instructions. +That doesn't need to sleep, and can safely be done from inside IRQ handlers. + +Use these calls to access such GPIOs: + + /* GPIO INPUT: return zero or nonzero */ + int gpio_get_value(unsigned gpio); + + /* GPIO OUTPUT */ + void gpio_set_value(unsigned gpio, int value); + +The values are boolean, zero for low, nonzero for high. When reading the +value of an output pin, the value returned should be what's seen on the +pin ... that won't always match the specified output value, because of +issues including wire-OR and output latencies. + +The get/set calls have no error returns because "invalid GPIO" should have +been reported earlier in gpio_set_direction(). However, note that not all +platforms can read the value of output pins; those that can't should always +return zero. Also, these calls will be ignored for GPIOs that can't safely +be accessed wihtout sleeping (see below). + +Platform-specific implementations are encouraged to optimise the two +calls to access the GPIO value in cases where the GPIO number (and for +output, value) are constant. It's normal for them to need only a couple +of instructions in such cases (reading or writing a hardware register), +and not to need spinlocks. Such optimized calls can make bitbanging +applications a lot more efficient (in both space and time) than spending +dozens of instructions on subroutine calls. + + +GPIO access that may sleep +-------------------------- +Some GPIO controllers must be accessed using message based busses like I2C +or SPI. Commands to read or write those GPIO values require waiting to +get to the head of a queue to transmit a command and get its response. +This requires sleeping, which can't be done from inside IRQ handlers. + +Platforms that support this type of GPIO distinguish them from other GPIOs +by returning nonzero from this call: + + int gpio_cansleep(unsigned gpio); + +To access such GPIOs, a different set of accessors is defined: + + /* GPIO INPUT: return zero or nonzero, might sleep */ + int gpio_get_value_cansleep(unsigned gpio); + + /* GPIO OUTPUT, might sleep */ + void gpio_set_value_cansleep(unsigned gpio, int value); + +Other than the fact that these calls might sleep, and will not be ignored +for GPIOs that can't be accessed from IRQ handlers, these calls act the +same as the spinlock-safe calls. + + +Claiming and Releasing GPIOs (OPTIONAL) +--------------------------------------- +To help catch system configuration errors, two calls are defined. +However, many platforms don't currently support this mechanism. + + /* request GPIO, returning 0 or negative errno. + * non-null labels may be useful for diagnostics. + */ + int gpio_request(unsigned gpio, const char *label); + + /* release previously-claimed GPIO */ + void gpio_free(unsigned gpio); + +Passing invalid GPIO numbers to gpio_request() will fail, as will requesting +GPIOs that have already been claimed with that call. The return value of +gpio_request() must be checked. (These calls could sleep.) + +These calls serve two basic purposes. One is marking the signals which +are actually in use as GPIOs, for better diagnostics; systems may have +several hundred potential GPIOs, but often only a dozen are used on any +given board. Another is to catch conflicts between drivers, reporting +errors when drivers wrongly think they have exclusive use of that signal. + +These two calls are optional because not not all current Linux platforms +offer such functionality in their GPIO support; a valid implementation +could return success for all gpio_request() calls. Unlike the other calls, +the state they represent doesn't normally match anything from a hardware +register; it's just a software bitmap which clearly is not necessary for +correct operation of hardware or (bug free) drivers. + +Note that requesting a GPIO does NOT cause it to be configured in any +way; it just marks that GPIO as in use. Separate code must handle any +pin setup (e.g. controlling which pin the GPIO uses, pullup/pulldown). + + +GPIOs mapped to IRQs +-------------------- +GPIO numbers are unsigned integers; so are IRQ numbers. These make up +two logically distinct namespaces (GPIO 0 need not use IRQ 0). You can +map between them using calls like: + + /* map GPIO numbers to IRQ numbers */ + int gpio_to_irq(unsigned gpio); + + /* map IRQ numbers to GPIO numbers */ + int irq_to_gpio(unsigned irq); + +Those return either the corresponding number in the other namespace, or +else a negative errno code if the mapping can't be done. (For example, +some GPIOs can't used as IRQs.) It is an unchecked error to use a GPIO +number that hasn't been marked as an input using gpio_set_direction(), or +to use an IRQ number that didn't originally come from gpio_to_irq(). + +These two mapping calls are expected to cost on the order of a single +addition or subtraction. They're not allowed to sleep. + +Non-error values returned from gpio_to_irq() can be passed to request_irq() +or free_irq(). They will often be stored into IRQ resources for platform +devices, by the board-specific initialization code. Note that IRQ trigger +options are part of the IRQ interface, e.g. IRQF_TRIGGER_FALLING, as are +system wakeup capabilities. + +Non-error values returned from irq_to_gpio() would most commonly be used +with gpio_get_value(). + + + +What do these conventions omit? +=============================== +One of the biggest things these conventions omit is pin multiplexing, since +this is highly chip-specific and nonportable. One platform might not need +explicit multiplexing; another might have just two options for use of any +given pin; another might have eight options per pin; another might be able +to route a given GPIO to any one of several pins. (Yes, those examples all +come from systems that run Linux today.) + +Related to multiplexing is configuration and enabling of the pullups or +pulldowns integrated on some platforms. Not all platforms support them, +or support them in the same way; and any given board might use external +pullups (or pulldowns) so that the on-chip ones should not be used. + +There are other system-specific mechanisms that are not specified here, +like the aforementioned options for input de-glitching and wire-OR output. +Hardware may support reading or writing GPIOs in gangs, but that's usually +configuration dependednt: for GPIOs sharing the same bank. (GPIOs are +commonly grouped in banks of 16 or 32, with a given SOC having several such +banks.) Code relying on such mechanisms will necessarily be nonportable. + +Dynamic definition of GPIOs is not currently supported; for example, as +a side effect of configuring an add-on board with some GPIO expanders. + +These calls are purely for kernel space, but a userspace API could be built +on top of it. diff --git a/include/asm-arm/gpio.h b/include/asm-arm/gpio.h new file mode 100644 index 000000000000..fff4f800ee42 --- /dev/null +++ b/include/asm-arm/gpio.h @@ -0,0 +1,7 @@ +#ifndef _ARCH_ARM_GPIO_H +#define _ARCH_ARM_GPIO_H + +/* not all ARM platforms necessarily support this API ... */ +#include + +#endif /* _ARCH_ARM_GPIO_H */ diff --git a/include/asm-generic/gpio.h b/include/asm-generic/gpio.h new file mode 100644 index 000000000000..2d0aab1d8611 --- /dev/null +++ b/include/asm-generic/gpio.h @@ -0,0 +1,25 @@ +#ifndef _ASM_GENERIC_GPIO_H +#define _ASM_GENERIC_GPIO_H + +/* platforms that don't directly support access to GPIOs through I2C, SPI, + * or other blocking infrastructure can use these wrappers. + */ + +static inline int gpio_cansleep(unsigned gpio) +{ + return 0; +} + +static inline int gpio_get_value_cansleep(unsigned gpio) +{ + might_sleep(); + return gpio_get_value(gpio); +} + +static inline void gpio_set_value_cansleep(unsigned gpio, int value) +{ + might_sleep(); + gpio_set_value(gpio, value); +} + +#endif /* _ASM_GENERIC_GPIO_H */ From 3c729f1ecd23b86a2d6b211d646f57f9da8dfeb1 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Mon, 12 Feb 2007 00:53:12 -0800 Subject: [PATCH 1017/1200] [PATCH] OMAP GPIO wrappers This teaches OMAP how to implement the cross-platform GPIO interfaces.

The issue is a concurrency issue with some internal CAPI data structure which can crash the kernel. On my FritzCard DSL with the AVM driver it crashes about once a day without this workaround patch. With this workaround patch it's rock-stable (at least on UP, but I don't see why this shouldn't work on SMP as well. But maybe I'm missing something.) This workaround is kind of a sledgehammer which inserts a global lock to wrap around all the critical sections. Of course, this is a scalability issue, if you have many ISDN/CAPI cards. But it prevents a crash. So I vote for this fix to get merged, until people come up with a better solution. Better have a stable kernel that's less scalable, than a crashing and useless kernel. This bug is in the kernel since 2.6.15 (at least).

It manages encryption/decryption request queues with a transport mechanism. Currently, netlink is the only implemented transport. Each inode has a unique File Encryption Key (FEK). Under passphrase, a File Encryption Key Encryption Key (FEKEK) is generated from a salt/passphrase combo on mount. This FEKEK encrypts each FEK and writes it into the header of each file using the packet format specified in RFC 2440. This is all symmetric key encryption, so it can all be done via the kernel crypto API. These new patches introduce public key encryption of the FEK. There is no asymmetric key encryption support in the kernel crypto API, so eCryptfs pushes the FEK encryption and decryption out to a userspace daemon. After considering our requirements and determining the complexity of using various transport mechanisms, we settled on netlink for this communication. eCryptfs stores authentication tokens into the kernel keyring. These tokens correlate with individual keys. For passphrase mode of operation, the authentication token contains the symmetric FEKEK. For public key, the authentication token contains a PKI type and an opaque data blob managed by individual PKI modules in userspace. Each user who opens a file under an eCryptfs partition mounted in public key mode must be running a daemon. That daemon has the user's credentials and has access to all of the keys to which the user should have access. The daemon, when started, initializes the pluggable PKI modules available on the system and registers itself with the eCryptfs kernel module. Userspace utilities register public key authentication tokens into the user session keyring. These authentication tokens correlate key signatures with PKI modules and PKI blobs. The PKI blobs contain PKI-specific information necessary for the PKI module to carry out asymmetric key encryption and decryption. When the eCryptfs module parses the header of an existing file and finds a Tag 1 (Public Key) packet (see RFC 2440), it reads in the public key identifier (signature). The asymmetrically encrypted FEK is in the Tag 1 packet; eCryptfs puts together a decrypt request packet containing the signature and the encrypted FEK, then it passes it to the daemon registered for the current->euid via a netlink unicast to the PID of the daemon, which was registered at the time the daemon was started by the user. The daemon actually just makes calls to libecryptfs, which implements request packet parsing and manages PKI modules. libecryptfs grabs the public key authentication token for the given signature from the user session keyring. This auth tok tells libecryptfs which PKI module should receive the request. libecryptfs then makes a decrypt() call to the PKI module, and it passes along the PKI block from the auth tok. The PKI uses the blob to figure out how it should decrypt the data passed to it; it performs the decryption and passes the decrypted data back to libecryptfs. libecryptfs then puts together a reply packet with the decrypted FEK and passes that back to the eCryptfs module. The eCryptfs module manages these request callouts to userspace code via message context structs. The module maintains an array of message context structs and places the elements of the array on two lists: a free and an allocated list. When eCryptfs wants to make a request, it moves a msg ctx from the free list to the allocated list, sets its state to pending, and fires off the message to the user's registered daemon. When eCryptfs receives a netlink message (via the callback), it correlates the msg ctx struct in the alloc list with the data in the message itself. The msg->index contains the offset of the array of msg ctx structs. It verifies that the registered daemon PID is the same as the PID of the process that sent the message. It also validates a sequence number between the received packet and the msg ctx. Then, it copies the contents of the message (the reply packet) into the msg ctx struct, sets the state in the msg ctx to done, and wakes up the process that was sleeping while waiting for the reply. The sleeping process was whatever was performing the sys_open(). This process originally called ecryptfs_send_message(); it is now in ecryptfs_wait_for_response(). When it wakes up and sees that the msg ctx state was set to done, it returns a pointer to the message contents (the reply packet) and returns. If all went well, this packet contains the decrypted FEK, which is then copied into the crypt_stat struct, and life continues as normal. The case for creation of a new file is very similar, only instead of a decrypt request, eCryptfs sends out an encrypt request. > - We have a great clod of key mangement code in-kernel. Why is that > not suitable (or growable) for public key management? eCryptfs uses Howells' keyring to store persistent key data and PKI state information. It defers public key cryptographic transformations to userspace code. The userspace data manipulation request really is orthogonal to key management in and of itself. What eCryptfs basically needs is a secure way to communicate with a particular daemon for a particular task doing a syscall, based on the UID. Nothing running under another UID should be able to access that channel of communication. > - Is it appropriate that new infrastructure for public key > management be private to a particular fs? The messaging.c file contains a lot of code that, perhaps, could be extracted into a separate kernel service. In essence, this would be a sort of request/reply mechanism that would involve a userspace daemon. I am not aware of anything that does quite what eCryptfs does, so I was not aware of any existing tools to do just what we wanted. > What happens if one of these daemons exits without sending a quit > message? There is a stale uid<->pid association in the hash table for that user. When the user registers a new daemon, eCryptfs cleans up the old association and generates a new one. See ecryptfs_process_helo(). > - _why_ does it use netlink? Netlink provides the transport mechanism that would minimize the complexity of the implementation, given that we can have multiple daemons (one per user). I explored the possibility of using relayfs, but that would involve having to introduce control channels and a protocol for creating and tearing down channels for the daemons. We do not have to worry about any of that with netlink.

This patch set implements two new mount options: ecryptfs_xattr_metadata - When set, newly created files will have their cryptographic metadata stored in the extended attribute region of the file rather than the header. When storing the data in the file header, there is a minimum of 8KB reserved for the header information for each file, making each file at least 12KB in size. This can take up a lot of extra disk space if the user creates a lot of small files. By storing the data in the extended attribute, each file will only occupy at least of 4KB of space. As the eCryptfs metadata set becomes larger with new features such as multi-key associations, most popular filesystems will not be able to store all of the information in the xattr region in some cases due to space constraints. However, the majority of users will only ever associate one key per file, so most users will be okay with storing their data in the xattr region. This option should be used with caution. I want to emphasize that the xattr must be maintained under all circumstances, or the file will be rendered permanently unrecoverable. The last thing I want is for a user to forget to set an xattr flag in a backup utility, only to later discover that their backups are worthless. ecryptfs_encrypted_view - When set, this option causes eCryptfs to present applications a view of encrypted files as if the cryptographic metadata were stored in the file header, whether the metadata is actually stored in the header or in the extended attributes. No matter what eCryptfs winds up doing in the lower filesystem, I want to preserve a baseline format compatibility for the encrypted files. As of right now, the metadata may be in the file header or in an xattr. There is no reason why the metadata could not be put in a separate file in future versions. Without the compatibility mode, backup utilities would have to know to back up the metadata file along with the files. The semantics of eCryptfs have always been that the lower files are self-contained units of encrypted data, and the only additional information required to decrypt any given eCryptfs file is the key. That is what has always been emphasized about eCryptfs lower files, and that is what users expect. Providing the encrypted view option will provide a way to userspace applications wherein they can always get to the same old familiar eCryptfs encrypted files, regardless of what eCryptfs winds up doing with the metadata behind the scenes. This patch: Add extended attribute support to version bit vector, flags to indicate when xattr or encrypted view modes are enabled, and support for the new mount options.

This mode of operation is useful for applications like incremental backup utilities that do not preserve the extended attributes when directly accessing the lower files.

It does this so that two concurrent write() callers don't make a mess of f_pos, and of the file contents. ecryptfs should be calling vfs_write(). That way we also get the fsnotify notifications, which ecryptfs presently appears to have subverted. Convert direct calls to f_op->write() into calls to vfs_write().

Most architectures stores two copies of this buffer, one for future reference and one for parameter parsing. Current kernel command-line size for most architecture is much too small for module parameters, video settings, initramfs paramters and much more. The problem is that setting COMMAND_LINE_SIZE to a grater value, allocates static buffers. In order to allow a greater command-line size, these buffers should be dynamically allocated or marked as init disposable buffers, so unused memory can be released. This patch renames the static saved_command_line variable into boot_command_line adding __initdata attribute, so that it can be disposed after initialization. This rename is required so applications that use saved_command_line will not be affected by this change. It reintroduces saved_command_line as dynamically allocated buffer to match the data in boot_command_line. It also mark secondary command-line buffer as __initdata, and copies it to dynamically allocated static_command_line buffer components may hold reference to it after initialization. This patch is for linux-2.6.20-rc4-mm1 and is divided to target each architecture. I could not check this in any architecture so please forgive me if I got it wrong. The per-architecture modification is very simple, use boot_command_line in place of saved_command_line. The common code is the change into dynamic command-line. This patch: 1. Rename saved_command_line into boot_command_line, mark as init disposable. 2. Add dynamic allocated saved_command_line. 3. Add dynamic allocated static_command_line. 4. During startup copy: boot_command_line into saved_command_line. arch command_line into static_command_line. 5. Parse static_command_line and not arch command_line, so arch command_line may be freed.

UFS2 - is default file system for recent versions of FreeBSD. The main differences from UFS1 from write support point of view are: 1)Not all inodes are allocated during formatation of disk. 2)All meta-data(pointer to data blocks) are 64bit(in UFS1 they are 32bit). So patch series consist of 1)make possible mount UFS2 in read-write mode 2)code to write ufs2 inodes and code to initialize inodes chunks. 3)work with 64bit meta-data I made simple testing like create/deleting/writing/reading/truncating, also I ran fsx-linux and untar and build kernel on UFS1 and UFS2, after that FreeBSD fsck do not find any errors in fs. This patch makes possible to mount ufs2 "rw", and updates UFS2 documentation: remove note about bug(it fixed by reallocate blocks on the fly patch) and add me in the list of people who want receive bug reports.

Note that this is orthogonal to suspending and resuming an individual guest to a file. A side effect of implementing suspend/resume is that cpu hotplug is now supported. This should please the owners of big iron. This patch: KVM wants the cpu hotplug notifications, both for cpu hotplug itself, but more commonly for host suspend/resume. In order to avoid extensive #ifdefs, provide stubs when CONFIG_CPU_HOTPLUG is not defined.

(akpm: We kind-of have support for this hardware already, but... virgefb.c - amiga/zorro specific, - broken (according to Kconfig), - uses obsolete/nonexistent interface (struct display_switch) - recent Adrian Bunk's patch removes this driver S3triofb.c - ppc/openfirmware specific - minimal functionality - broken (according to Kconfig), - uses obsolete/nonexistent interface (struct display_switch) ) Signed-off-by: Ondrej Zajicek Cc: James Simmons Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- Documentation/fb/s3fb.txt | 78 +++ drivers/video/Kconfig | 19 + drivers/video/Makefile | 2 + drivers/video/s3fb.c | 1180 +++++++++++++++++++++++++++++++++++++ drivers/video/svgalib.c | 632 ++++++++++++++++++++ include/linux/fb.h | 7 + include/linux/svga.h | 124 ++++ 7 files changed, 2042 insertions(+) create mode 100644 Documentation/fb/s3fb.txt create mode 100644 drivers/video/s3fb.c create mode 100644 drivers/video/svgalib.c create mode 100644 include/linux/svga.h diff --git a/Documentation/fb/s3fb.txt b/Documentation/fb/s3fb.txt new file mode 100644 index 000000000000..8a04c0da0c91 --- /dev/null +++ b/Documentation/fb/s3fb.txt @@ -0,0 +1,78 @@ + + s3fb - fbdev driver for S3 Trio/Virge chips + =========================================== + + +Supported Hardware +================== + + S3 Trio32 + S3 Trio64 (and variants V+, UV+, V2/DX, V2/GX) + S3 Virge (and variants VX, DX, GX and GX2+) + S3 Plato/PX (completely untested) + S3 Aurora64V+ (completely untested) + + - only PCI bus supported + - only BIOS initialized VGA devices supported + - probably not working on big endian + +I tested s3fb on Trio64 (plain, V+ and V2/DX) and Virge (plain, VX, DX), +all on i386. + + +Supported Features +================== + + * 4 bpp pseudocolor modes (with 18bit palette, two variants) + * 8 bpp pseudocolor mode (with 18bit palette) + * 16 bpp truecolor modes (RGB 555 and RGB 565) + * 24 bpp truecolor mode (RGB 888) on (only on Virge VX) + * 32 bpp truecolor mode (RGB 888) on (not on Virge VX) + * text mode (activated by bpp = 0) + * interlaced mode variant (not available in text mode) + * doublescan mode variant (not available in text mode) + * panning in both directions + * suspend/resume support + * DPMS support + +Text mode is supported even in higher resolutions, but there is limitation +to lower pixclocks (maximum between 50-60 MHz, depending on specific hardware). +This limitation is not enforced by driver.
