on the setup, so I think that the choice on what firmware to make
persistent should be left to userspace.
- Why register_firmware()+__init can be useful:
- For boot devices needing firmware.
- To make the transition easier:
The firmware can be declared __init and register_firmware()
called on module_init. Then the firmware is warranted to be
there even if "firmware hotplug userspace" is not there yet or
it doesn't yet provide the needed firmware.
Once the firmware is widely available in userspace, it can be
removed from the kernel. Or made optional (CONFIG_.*_FIRMWARE).
In either case, if firmware hotplug support is there, it can move the
firmware out of kernel memory into the real filesystem for later
usage.
Note: If persistence is implemented on top of initramfs,
register_firmware() may not be appropriate.

1. Introduction
Linux distinguishes between administrative and operational state of an
interface. Admininstrative state is the result of "ip link set dev
<dev> up or down" and reflects whether the administrator wants to use
the device for traffic.
However, an interface is not usable just because the admin enabled it
- ethernet requires to be plugged into the switch and, depending on
a site's networking policy and configuration, an 802.1X authentication
to be performed before user data can be transferred. Operational state
shows the ability of an interface to transmit this user data.
Thanks to 802.1X, userspace must be granted the possibility to
influence operational state. To accommodate this, operational state is
split into two parts: Two flags that can be set by the driver only, and
a RFC2863 compatible state that is derived from these flags, a policy,
and changeable from userspace under certain rules.
2. Querying from userspace
Both admin and operational state can be queried via the netlink
operation RTM_GETLINK. It is also possible to subscribe to RTMGRP_LINK
to be notified of updates. This is important for setting from userspace.
These values contain interface state:
ifinfomsg::if_flags & IFF_UP:
Interface is admin up
ifinfomsg::if_flags & IFF_RUNNING:
Interface is in RFC2863 operational state UP or UNKNOWN. This is for
backward compatibility, routing daemons, dhcp clients can use this
flag to determine whether they should use the interface.
ifinfomsg::if_flags & IFF_LOWER_UP:
Driver has signaled netif_carrier_on()
ifinfomsg::if_flags & IFF_DORMANT:
Driver has signaled netif_dormant_on()
These interface flags can also be queried without netlink using the
SIOCGIFFLAGS ioctl.
TLV IFLA_OPERSTATE
contains RFC2863 state of the interface in numeric representation:
IF_OPER_UNKNOWN (0):
Interface is in unknown state, neither driver nor userspace has set
operational state. Interface must be considered for user data as
setting operational state has not been implemented in every driver.
IF_OPER_NOTPRESENT (1):
Unused in current kernel (notpresent interfaces normally disappear),
just a numerical placeholder.
IF_OPER_DOWN (2):
Interface is unable to transfer data on L1, f.e. ethernet is not
plugged or interface is ADMIN down.
IF_OPER_LOWERLAYERDOWN (3):
Interfaces stacked on an interface that is IF_OPER_DOWN show this
state (f.e. VLAN).
IF_OPER_TESTING (4):
Unused in current kernel.
IF_OPER_DORMANT (5):
Interface is L1 up, but waiting for an external event, f.e. for a
protocol to establish. (802.1X)
IF_OPER_UP (6):
Interface is operational up and can be used.
This TLV can also be queried via sysfs.
TLV IFLA_LINKMODE
contains link policy. This is needed for userspace interaction
described below.
This TLV can also be queried via sysfs.
3. Kernel driver API
Kernel drivers have access to two flags that map to IFF_LOWER_UP and
IFF_DORMANT. These flags can be set from everywhere, even from
interrupts. It is guaranteed that only the driver has write access,
however, if different layers of the driver manipulate the same flag,
the driver has to provide the synchronisation needed.
__LINK_STATE_NOCARRIER, maps to !IFF_LOWER_UP:
The driver uses netif_carrier_on() to clear and netif_carrier_off() to
set this flag. On netif_carrier_off(), the scheduler stops sending
packets. The name 'carrier' and the inversion are historical, think of
it as lower layer.
netif_carrier_ok() can be used to query that bit.
__LINK_STATE_DORMANT, maps to IFF_DORMANT:
Set by the driver to express that the device cannot yet be used
because some driver controlled protocol establishment has to
complete. Corresponding functions are netif_dormant_on() to set the
flag, netif_dormant_off() to clear it and netif_dormant() to query.
On device allocation, networking core sets the flags equivalent to
netif_carrier_ok() and !netif_dormant().
Whenever the driver CHANGES one of these flags, a workqueue event is
scheduled to translate the flag combination to IFLA_OPERSTATE as
follows:
!netif_carrier_ok():
IF_OPER_LOWERLAYERDOWN if the interface is stacked, IF_OPER_DOWN
otherwise. Kernel can recognise stacked interfaces because their
ifindex != iflink.
netif_carrier_ok() && netif_dormant():
IF_OPER_DORMANT
netif_carrier_ok() && !netif_dormant():
IF_OPER_UP if userspace interaction is disabled. Otherwise
IF_OPER_DORMANT with the possibility for userspace to initiate the
IF_OPER_UP transition afterwards.
4. Setting from userspace
Applications have to use the netlink interface to influence the
RFC2863 operational state of an interface. Setting IFLA_LINKMODE to 1
via RTM_SETLINK instructs the kernel that an interface should go to
IF_OPER_DORMANT instead of IF_OPER_UP when the combination
netif_carrier_ok() && !netif_dormant() is set by the
driver. Afterwards, the userspace application can set IFLA_OPERSTATE
to IF_OPER_DORMANT or IF_OPER_UP as long as the driver does not set
netif_carrier_off() or netif_dormant_on(). Changes made by userspace
are multicasted on the netlink group RTMGRP_LINK.
So basically a 802.1X supplicant interacts with the kernel like this:
-subscribe to RTMGRP_LINK
-set IFLA_LINKMODE to 1 via RTM_SETLINK
-query RTM_GETLINK once to get initial state
-if initial flags are not (IFF_LOWER_UP && !IFF_DORMANT), wait until
netlink multicast signals this state
-do 802.1X, eventually abort if flags go down again
-send RTM_SETLINK to set operstate to IF_OPER_UP if authentication
succeeds, IF_OPER_DORMANT otherwise
-see how operstate and IFF_RUNNING is echoed via netlink multicast
-set interface back to IF_OPER_DORMANT if 802.1X reauthentication
fails
-restart if kernel changes IFF_LOWER_UP or IFF_DORMANT flag
if supplicant goes down, bring back IFLA_LINKMODE to 0 and
IFLA_OPERSTATE to a sane value.
A routing daemon or dhcp client just needs to care for IFF_RUNNING or
waiting for operstate to go IF_OPER_UP/IF_OPER_UNKNOWN before
considering the interface / querying a DHCP address.

Older Version : 2.20.4.7 (scsi module), 2.20.2.6 (cmm module)
1. Fixed a bug in megaraid_reset_handler().
Customer reported "Unable to handle kernel NULL pointer dereference
at virtual address 00000000" when system goes to reset condition
for some reason. It happened randomly.
Root Cause: in the megaraid_reset_handler(), there is possibility not
returning pending packets in the pend_list if there are multiple
pending packets.
Fix: Made the change in the driver so that it will return all packets
in the pend_list.
2. Added change request.
As found in the following URL, rmb() only didn't help the
problem. I had to increase the loop counter to 0xFFFFFF. (6 F's)

PXA2xx SPI on SSP driver HOWTO
===================================================
This a mini howto on the pxa2xx_spi driver. The driver turns a PXA2xx
synchronous serial port into a SPI master controller
(see Documentation/spi/spi_summary). The driver has the following features
- Support for any PXA2xx SSP
- SSP PIO and SSP DMA data transfers.
- External and Internal (SSPFRM) chip selects.
- Per slave device (chip) configuration.
- Full suspend, freeze, resume support.
The driver is built around a "spi_message" fifo serviced by workqueue and a
tasklet. The workqueue, "pump_messages", drives message fifo and the tasklet
(pump_transfer) is responsible for queuing SPI transactions and setting up and
launching the dma/interrupt driven transfers.
Declaring PXA2xx Master Controllers
-----------------------------------
Typically a SPI master is defined in the arch/.../mach-*/board-*.c as a
"platform device". The master configuration is passed to the driver via a table
found in include/asm-arm/arch-pxa/pxa2xx_spi.h:
struct pxa2xx_spi_master {
enum pxa_ssp_type ssp_type;
u32 clock_enable;
u16 num_chipselect;
u8 enable_dma;
};
The "pxa2xx_spi_master.ssp_type" field must have a value between 1 and 3 and
informs the driver which features a particular SSP supports.
The "pxa2xx_spi_master.clock_enable" field is used to enable/disable the
corresponding SSP peripheral block in the "Clock Enable Register (CKEN"). See
the "PXA2xx Developer Manual" section "Clocks and Power Management".
The "pxa2xx_spi_master.num_chipselect" field is used to determine the number of
slave device (chips) attached to this SPI master.
The "pxa2xx_spi_master.enable_dma" field informs the driver that SSP DMA should
be used. This caused the driver to acquire two DMA channels: rx_channel and
tx_channel. The rx_channel has a higher DMA service priority the tx_channel.
See the "PXA2xx Developer Manual" section "DMA Controller".
NSSP MASTER SAMPLE
------------------
Below is a sample configuration using the PXA255 NSSP.
static struct resource pxa_spi_nssp_resources[] = {
[0] = {
.start = __PREG(SSCR0_P(2)), /* Start address of NSSP */
.end = __PREG(SSCR0_P(2)) + 0x2c, /* Range of registers */
.flags = IORESOURCE_MEM,
},
[1] = {
.start = IRQ_NSSP, /* NSSP IRQ */
.end = IRQ_NSSP,
.flags = IORESOURCE_IRQ,
},
};
static struct pxa2xx_spi_master pxa_nssp_master_info = {
.ssp_type = PXA25x_NSSP, /* Type of SSP */
.clock_enable = CKEN9_NSSP, /* NSSP Peripheral clock */
.num_chipselect = 1, /* Matches the number of chips attached to NSSP */
.enable_dma = 1, /* Enables NSSP DMA */
};
static struct platform_device pxa_spi_nssp = {
.name = "pxa2xx-spi", /* MUST BE THIS VALUE, so device match driver */
.id = 2, /* Bus number, MUST MATCH SSP number 1..n */
.resource = pxa_spi_nssp_resources,
.num_resources = ARRAY_SIZE(pxa_spi_nssp_resources),
.dev = {
.platform_data = &pxa_nssp_master_info, /* Passed to driver */
},
};
static struct platform_device *devices[] __initdata = {
&pxa_spi_nssp,
};
static void __init board_init(void)
{
(void)platform_add_device(devices, ARRAY_SIZE(devices));
}
Declaring Slave Devices
-----------------------
Typically each SPI slave (chip) is defined in the arch/.../mach-*/board-*.c
using the "spi_board_info" structure found in "linux/spi/spi.h". See
"Documentation/spi/spi_summary" for additional information.
Each slave device attached to the PXA must provide slave specific configuration
information via the structure "pxa2xx_spi_chip" found in
"include/asm-arm/arch-pxa/pxa2xx_spi.h". The pxa2xx_spi master controller driver
will uses the configuration whenever the driver communicates with the slave
device.
struct pxa2xx_spi_chip {
u8 tx_threshold;
u8 rx_threshold;
u8 dma_burst_size;
u32 timeout_microsecs;
u8 enable_loopback;
void (*cs_control)(u32 command);
};
The "pxa2xx_spi_chip.tx_threshold" and "pxa2xx_spi_chip.rx_threshold" fields are
used to configure the SSP hardware fifo. These fields are critical to the
performance of pxa2xx_spi driver and misconfiguration will result in rx
fifo overruns (especially in PIO mode transfers). Good default values are
.tx_threshold = 12,
.rx_threshold = 4,
The "pxa2xx_spi_chip.dma_burst_size" field is used to configure PXA2xx DMA
engine and is related the "spi_device.bits_per_word" field. Read and understand
the PXA2xx "Developer Manual" sections on the DMA controller and SSP Controllers
to determine the correct value. An SSP configured for byte-wide transfers would
use a value of 8.
The "pxa2xx_spi_chip.timeout_microsecs" fields is used to efficiently handle
trailing bytes in the SSP receiver fifo. The correct value for this field is
dependent on the SPI bus speed ("spi_board_info.max_speed_hz") and the specific
slave device. Please note the the PXA2xx SSP 1 does not support trailing byte
timeouts and must busy-wait any trailing bytes.
The "pxa2xx_spi_chip.enable_loopback" field is used to place the SSP porting
into internal loopback mode. In this mode the SSP controller internally
connects the SSPTX pin the the SSPRX pin. This is useful for initial setup
testing.
The "pxa2xx_spi_chip.cs_control" field is used to point to a board specific
function for asserting/deasserting a slave device chip select. If the field is
NULL, the pxa2xx_spi master controller driver assumes that the SSP port is
configured to use SSPFRM instead.
NSSP SALVE SAMPLE
-----------------
The pxa2xx_spi_chip structure is passed to the pxa2xx_spi driver in the
"spi_board_info.controller_data" field. Below is a sample configuration using
the PXA255 NSSP.

};
static void __init streetracer_init(void)
{
spi_register_board_info(streetracer_spi_board_info,
ARRAY_SIZE(streetracer_spi_board_info));
}
DMA and PIO I/O Support
-----------------------
The pxa2xx_spi driver support both DMA and interrupt driven PIO message
transfers. The driver defaults to PIO mode and DMA transfers must enabled by
setting the "enable_dma" flag in the "pxa2xx_spi_master" structure and and
ensuring that the "pxa2xx_spi_chip.dma_burst_size" field is non-zero. The DMA
mode support both coherent and stream based DMA mappings.
The following logic is used to determine the type of I/O to be used on
a per "spi_transfer" basis:
if !enable_dma or dma_burst_size == 0 then
always use PIO transfers
if spi_message.is_dma_mapped and rx_dma_buf != 0 and tx_dma_buf != 0 then
use coherent DMA mode
if rx_buf and tx_buf are aligned on 8 byte boundary then
use streaming DMA mode
otherwise
use PIO transfer

After you initialize the spi_master, then use spi_register_master() to

If you need to remove your SPI controller driver, spi_unregister_master()

BUS NUMBERING
Bus numbering is important, since that's how Linux identifies a given
SPI bus (shared SCK, MOSI, MISO). Valid bus numbers start at zero. On
SOC systems, the bus numbers should match the numbers defined by the chip
manufacturer. For example, hardware controller SPI2 would be bus number 2,
and spi_board_info for devices connected to it would use that number.
If you don't have such hardware-assigned bus number, and for some reason
you can't just assign them, then provide a negative bus number. That will
then be replaced by a dynamically assigned number. You'd then need to treat
this as a non-static configuration (see above).
