Stanislaw Gruszka ef442b73b6 mt76x0: antenna select corrections
Update mt76x0_phy_ant_select() to conform vendor driver, most notably
add dual antenna mode support, read configuration from EEPROM and
move ant select out of channel config to init phase. Plus small MT7630E
quirk for MT_CMB_CTRL register which vendor driver dedicated to this
chip do.

This make MT7630E workable with mt76x0e driver and do not cause any
problems on MT7610U for me.

[   31.096533] Disabling lock debugging due to kernel taint

It appears that when trying to determine the length of the string in the
alternate firmware path, we make the mistake of not handling the case
where the firmware path is empty correctly. Since strlen(mp_path) can
return 0, we'll end up accessing mp_path[-1] when the firmware_path
isn't provided through the module arguments.

So, fix this by just setting the end char to '\0' by default, and only
changing it if we have a non-zero length. Additionally, use strnlen()
with BRCMF_FW_ALTPATH_LEN instead of strlen() just to be extra safe.

Hans de Goede 554da3868e brcmfmac: Call brcmf_dmi_probe before brcmf_of_probe
ARM systems with UEFI may have both devicetree (of) and DMI data in this
case we end up setting brcmf_mp_device.board_type twice.

In this case we should prefer the devicetree data, because:
1) The devicerree data is more reliable
2) Some ARM systems (e.g. the Raspberry Pi 3 models) support both UEFI and
   classic uboot booting, the devicetree data is always there, so using it
   makes sure we ask for the same nvram file independent of how we booted.

This commit moves the brcmf_dmi_probe call to before the brcmf_of_probe
call, so that the latter can override the value of the first if both are
set.

Dan Haab 4282ff17e5 brcmfmac: support STA info struct v7
The newest firmwares provide STA info using v7 of the struct. As v7
isn't backward compatible, a union is needed.

Even though brcmfmac does not use any of the new info it's important to
provide the proper struct buffer. Without this change new firmwares will
fallback to the very limited v3 instead of something in between such as
v4.

Luca Coelho b1bbc1a636 iwlwifi: fix cfg structs for 22000 with different RF modules
We have to choose different configuration and different firmwares
depending on the external RF module that is installed.  Since the
external module is not represented in the PCI IDs, we need to change
the configuration at runtime, after checking the RF ID of the module
installed.  We have a bit of a mess in the code that does this,
because it applies cfg's according to the RF ID only, ignoring the
integrated module that is in use.

Fix that for some devices by adding correct configurations for them
and not ignoring the integrated module's type when making the
decision.

important to provide valid & complete info about supported bands for

Emmanuel Grumbach 82715ac71e iwlwifi: mvm: fix regulatory domain update when the firmware starts
When the firmware starts, it doesn't have any regulatory
information, hence it uses the world wide limitations. The
driver can feed the firmware with previous knowledge that
was kept in the driver, but the firmware may still not
update its internal tables.

This happens when we start a BSS interface, and then the
firmware can change the regulatory tables based on our
location and it'll use more lenient, location specific
rules. Then, if the firmware is shut down (when the
interface is brought down), and then an AP interface is
created, the firmware will forget the country specific
rules.

The host will think that we are in a certain country that
may allow channels and will try to teach the firmware about
our location, but the firmware may still not allow to drop
the world wide limitations and apply country specific rules
because it was just re-started.

In this case, the firmware will reply with MCC_RESP_ILLEGAL
to the MCC_UPDATE_CMD. In that case, iwlwifi needs to let
the upper layers (cfg80211 / hostapd) know that the channel
list they know about has been updated.

Shahar S Matityahu 8954e1eb22 iwlwifi: trans: Clear persistence bit when starting the FW
In D3 suspend flow in 9260 gen2 HW, the NIC receives two PERST signals.
The first PERST is expected and indicates the device on coming resume flow.
The second PERST causes FW restart FW restart.
In order to avoid this issue, the FW set the persistence bit on.
Once this bit is set, the FW ignores reset attempts.
The problem is when the FW gets assert during D3 and then the persistence
bit is set and causes the FW to ignore reset.
To handle this issue, the FW opens the preg bit which allows access
to the persistence bit, so that the driver clear the persistence bit
and reset the NIC.

The flow is as follows:
the driver checks if the persistence bit is set.
If the bit is set, the driver checks if he can clear the bit.
If the driver can not clear the bit then there is no point to continue
configuring the NIC since it will fail.

The fix was added is in start HW flow instead of the resume flow since in
general, if the persistence bit is set, the driver can not start the FW.
So it is good to check it when we start configuring the NIC.

The driver does not need to close the preg bit since the FW close it
during the start flow.

 * TX path, which doesn't take any locks anyway
 * iwl_mvm_wake_sw_queue() and iwl_mvm_stop_sw_queue() where we
   just (atomically) read a bitmap, so the lock isn't needed.

Therefore, we can remove the spinlock. This enables some cleanup
in the ugly locking in iwl_mvm_inactivity_check().

Johannes Berg 06bc6f6ed4 iwlwifi: mvm: synchronize TID queue removal
When we mark a TID as no longer having a queue, there's no
guarantee the TX path isn't using this txq_id right now,
having accessed it just before we reset the value. To fix
this, add synchronize_net() when we change the TIDs from
having a queue to not having one, so that we can then be
sure that the TX path is no longer accessing that queue.

David S. Miller 4a5a553dde brcmfmac: Use standard SKB list accessors in brcmf_sdiod_sglist_rw.
Instead of direct SKB list pointer accesses.

The loops in this function had to be rewritten to accommodate this
more easily.

The first loop iterates now over the target list in the outer loop,
and triggers an mmc data operation when the per-operation limits are
hit.

Then after the loops, if we have any residue, we trigger the last
and final operation.

For the page aligned workaround, where we have to copy the read data
back into the original list of SKBs, we use a two-tiered loop.  The
outer loop stays the same and iterates over pktlist, and then we have
an inner loop which uses skb_peek_next().  The break logic has been
simplified because we know that the aggregate length of the SKBs in
the source and destination lists are the same.

This change also ends up fixing a bug, having to do with the
maintainance of the seg_sz variable and how it drove the outermost
loop.  It begins as:

	seg_sz = target_list->qlen;

ie. the number of packets in the target_list queue.  The loop
structure was then:

	while (seq_sz) {
		...
		while (not at end of target_list) {
			...
			sg_cnt++
			...
		}
		...
		seg_sz -= sg_cnt;

The assumption built into that last statement is that sg_cnt counts
how many packets from target_list have been fully processed by the
inner loop.  But this not true.

If we hit one of the limits, such as the max segment size or the max
request size, we will break and copy a partial packet then contine
back up to the top of the outermost loop.

With the new loops we don't have this problem as we don't guard the
loop exit with a packet count, but instead use the progression of the
pkt_next SKB through the list to the end.  The general structure is:

	sg_cnt = 0;
	skb_queue_walk(target_list, pkt_next) {
		pkt_offset = 0;
		...
		sg_cnt++;
		...
		while (pkt_offset < pkt_next->len) {
			pkt_offset += sg_data_size;
			if (queued up max per request)
				mmc_submit_one();
		}
	}
	if (sg_cnt)
		mmc_submit_one();

The variables that maintain where we are in the MMC command state such
as req_sz, sg_cnt, and sgl are reset when we emit one of these full
sized requests.

James Prestwood c0a0189d82 mac80211_hwsim: allow configurable cipher types
The mac80211_hwsim driver does not specify supported cipher types, which
in turn enables all ciphers to be supported in software. (see
net/mac80211/main.c:ieee80211_init_cipher_suites). Allowing ciphers
to be configurable is valuable for simulating older drivers that may
not support all ciphers.

This patch adds a new attribute:

 - HWSIM_ATTR_CIPHER_SUPPORT
	A u32 array/list of supported cipher types

This only allows enabling/disabling cipher types listed in the (new)
"hwsim_ciphers" array in mac80211_hwsim.c. Any unknown cipher type
will result in -EINVAL.

James Prestwood 99e3a44bac mac80211_hwsim: allow setting iftype support
The mac80211_hwsim driver hard codes its supported interface types. For
testing purposes it would be valuable to allow changing these supported
types in order to simulate actual drivers than support a limited set of
iftypes. A new attribute was added to allow this:

- HWSIM_ATTR_IFTYPE_SUPPORT
	A u32 bit field of supported NL80211_IFTYPE_* bits

This will only enable/disable iftypes that mac80211_hwsim already
supports.

In order to accomplish this, the ieee80211_iface_limit structure needed
to be built dynamically to only include limit rules for iftypes that
the user requested to enable.

Hans de Goede 29ec3394f0 brcmfmac: Fix ccode from EFI nvram when necessary
In some cases the EFI-var stored nvram contains "ccode=ALL" or "ccode=XV"
to specify "worldwide" compatible settings, but these 2 ccode-s do not work
properly.

I've tested the different known "worldwide" ccode-s used in various nvram
sources with the latest firmwares from linux-firmware for various brcmfmac
models, here is a simplified (*) table with what each setting results in:

ALL: 12-14 disab, U-NII-1, U-NII-2 no-IR/radar, U-NII-3
XV:  12-14 no-IR, disables all 5G channels
XY:  12-13 enab, 14 disab, U-NII-1 enab, U-NII-2 no-IR/radar, U-NII-3 disab
X2:  12-13 no-IR, 14 dis, U-NII-1 no-IR, U-NII-2 no-IR/radar, U-NII-3 no-IR

Where 12,13,14 are 2.4G channels 12-14 and U-NII-1/2/3 are the 3 different
5G channel groups. no-IR is no-Initiate-Radiation, we will never send on
these channels without first having received valid wifi traffic there.

This immediately shows that both ALL and XV are not as worldwide as we want
them to be. ALL causes channels 12 and 13 to not be available and XV causes
all 5GHz channels to not be available. Also ALL unconditionally enables the
U-NII-1 and U-NII-3 5G groups, while we really should be using no-IR for
these.

This commit replace XV and ALL with X2, which allows usage of chan 12-13
and 5G channels, but only after receiving valid wifi traffic there first.

Note that this configure the firmware's channel limits, the kernels own
regulatory restrictions based on e.g. regulatory info received from the
access-point, will be applied on top of this.

This fixes channels 12+13 not working on the Asus T200TA and the Lenovo
Mixx 2 8 and 5G channels not working on the Asus T100HA.

This has been tested on the following models: Acer Iconia Tab8 w1-810,
Acer One 10, Asus T100CHI, Asus T100HA, Asus T100TA, Asus T200TA and a
Lenovo Mixx 2 8.

*) There are some exceptions to this table:
1) On really old firmware e.g. linux-firmware's 2011 brcmfmac4330-sdio.bin
   ALL really means all, unconditionally enabling everything
2) The exact meaning might be influenced by setting the regrev nvram var.
   Specifically using ccode=XV + regrev=1 on brcmfmac43241b4 leads to:
   12-14 no-ir, U-NII-1 no-ir, U-NII-2 no-ir/radar, U-NII-3 no-ir
   But only on the brcmfmac43241b4 and not on e.g. the brcmfmac43340

Hans de Goede ce2e6db554 brcmfmac: Add support for getting nvram contents from EFI variables
Various X86 laptops with a SDIO attached brcmfmac wifi chip, store the
nvram contents in a special EFI variable. This commit adds support for
getting nvram directly from this EFI variable, without the user needing
to manually copy it.

This makes Wifi / Bluetooth work out of the box on these devices instead of
requiring manual setup.

This has been tested on the following models: Acer Iconia Tab8 w1-810,
Acer One 10, Asus T100CHI, Asus T100HA, Asus T100TA, Asus T200TA and a

Since on some models these strings are too generic, this commit also adds

The nvram files which some brcmfmac chips need are board-specific. To be
able to distribute these as part of linux-firmware, so that devices with
such a wifi chip will work OOTB, multiple (one per board) versions must
co-exist under /lib/firmware.

This commit adds support for callers of the brcmfmac/firmware.c code to
pass in a board_type parameter through the request structure.

If that parameter is set then the code will first try to load
chipmodel.board_type.txt before falling back to the old chipmodel.txt name.

Hans de Goede 5b587496dc brcmfmac: Remove recursion from firmware load error handling
Before this commit brcmf_fw_request_done would call
brcmf_fw_request_next_item to load the next item, which on an error would
call brcmf_fw_request_done, which if the error is recoverable (*) will
then continue calling brcmf_fw_request_next_item for the next item again
which on an error will call brcmf_fw_request_done again...

This does not blow up because we only have a limited number of items so
we never recurse too deep. But the recursion is still quite ugly and
frankly is giving me a headache, so lets fix this.

This commit fixes this by removing brcmf_fw_request_next_item and by
making brcmf_fw_get_firmwares and brcmf_fw_request_done directly call
firmware_request_nowait resp. firmware_request themselves.

We don't really need a hard dependency here as the driver can presumably
work just fine without LEDs, so this follows the iwlwifi example and
adds a separate Kconfig option for the LED support, this will be available
whenever it will link, and otherwise the respective code gets left out from

It seems since we don't have a wakeirq value in the dts, the wakeirq
value in wl1271_probe() is zero, which then causes trouble in
irqd_get_trigger_type(irq_get_irq_data(wakeirq)).

This patch tries to address this by checking if wakeirq is zero,
and not trying to add it to the resources if that is the case.

Brian Norris bfe57a6ac7 ath10k: snoc: relax voltage requirements
I rarely see drivers specify precise voltage requirements like this, but
if we really have to...let's at least give a little wiggle room. Board
designs (and accompanying device trees) may not provide exactly the
voltage listed here, and we shouldn't fail to probe just because of
this.

Round these ranges down to the nearest volt, and provide a 0.05V margin.
The regulator should provide its own supported ranges, which will

I would just as well remove these ranges entirely, but if I understand
correctly, there's some reason that QCOM SoC's like to set zero /
non-zero voltages.

Brian Norris 1a1a0d5cce ath10k: snoc: fix unabalanced regulator error handling
If a regulator fails to set its voltage, we end up with an unbalanced
call to regulator_disable(), because the error path starts with the
current regulator (which was never enabled).

Factor out the "on" function to perform (and unwind if failed) a single
regulator at a time, and then main loop (ath10k_snoc_vreg_on()) can just
worry about unwinding the regulators that were already enabled.

It also helps to factor out the "off" function, to avoid repeating some
code here.

Rakesh Pillai 13104929d2 ath10k: fill the channel survey results for WCN3990 correctly
The host driver currently expects the channel info event to be
received in pairs for all the channels, i.e. the first
chan_info event for a particular channel will not have the
COMPLETE flag set and the second chan_info event for the
same channel will have the COMPLETE flag set.

The HL2.0 firmware sends only one channel info event per channel
which is scanned without the COMPLETE flag set. After sending the
chan_info_event for all the channels, the HL2.0 firmware sends a
chan_info_event with COMPLETE flag set to indicate the completion
of the channel info event.

The firmware does not indicate this behavior with any service bitmap
and hence a new firmware feature flag is used to handle the modified
parsing of the channel info events, in the host driver, for the
firmware which sends single channel info event per scanned channel.

we need to do core register only for the first FW_READY
indication, which is when we initialize the host driver.
All the subsequent FW_READY indication will be received

restart work. The state of driver is maintained using

We added an unnecessary condition here in commit a904417fc8 ("ath10k:
add extended per sta tx statistics support").  "legacy_rate_idx" is a u8
so it can't be negative.  The caller doesn't pass negatives either.  I
have deleted this code.

Carl Huang 0738b4998c ath10k: allocate small size dma memory in ath10k_pci_diag_write_mem
ath10k_pci_diag_write_mem may allocate big size of the dma memory
based on the parameter nbytes. Take firmware diag download as
example, the biggest size is about 500K. In some systems, the
allocation is likely to fail because it can't acquire such a large
contiguous dma memory.

The fix is to allocate a small size dma memory. In the loop,
driver copies the data to the allocated dma memory and writes to
the destination until all the data is written.

Tested with QCA6174 PCI with
firmware-6.bin_WLAN.RM.4.4.1-00119-QCARMSWP-1, this also affects
QCA9377 PCI.

Wen Gong 9de4162f09 ath10k: add peer flush in ath10k_flush for STATION
In the noisy environment, if there are packets in the queue and can't
send out, the suspend timing will be more than 5 seconds due to the wait,
flush the queue to optimize the suspend timing, and let the upper layer to
retry the packets after resume.

Tested with QCA6174 PCI with firmware

It's not a regression with new firmware releases.

There is no need to compare *ps_state_enable* with < 0 because
such variable is of type u8 (8 bits, unsigned), making it
impossible to hold a negative value.

Fix this by removing such comparison.

Wen Gong ce834e280f ath10k: support NET_DETECT WoWLAN feature
For WoWLAN support it is expected to support wake up based on discovery of
one or more known SSIDs. This is the WIPHY_WOWLAN_NET_DETECT feature,
which shows up as an NL80211 feature flag.

This shows up in 'iw phy' as:

WoWLAN support:
* wake up on network detection, up to 16 match sets

And it can be enabled with command:

iw phy0 wowlan enable net-detect interval 5000 delay 30 freqs 2412 matches ssid foo

Firmware will do scan by the configured parameters after suspend and
wakeup if it found matched SSIDs. Tested with QCA6174 hw3.0 with
firmware WLAN.RM.4.4.1-00110-QCARMSWPZ-1.

Currently the wmi command for setting probe request
oui, needed for mac randomization, is sent during
the mac register. At this time, during the driver
init the wmi has already been detached. This can
cause unexpected behavior since the firmware is
already down and the wmi has been detached.

Send the wmi command for setting probe request
oui during the driver start. This will make sure
that the firmware is started and wmi is initialized
before we send this command.
