Select to enable drivers based on the iwlwifi project. This

project provides a common foundation for Intel's wireless
|

drivers designed to use the mac80211 subsystem.
|

|

See <file:Documentation/networking/README.iwlwifi> for

information on the capabilities currently enabled in this

|

This option will enable debug tracing output for the iwlwifi
|
||||
drivers.
|
||||
|
||||
This will result in the kernel module being ~100k larger. You can
|
||||
control which debug output is sent to the kernel log by setting the
|
||||
value in
|
||||
|
||||
/sys/bus/pci/drivers/${DRIVER}/debug_level
|
||||
|
||||
This entry will only exist if this option is enabled.
|
||||
|
||||
To set a value, simply echo an 8-byte hex value to the same file:
|
||||
|
||||
% echo 0x43fff > /sys/bus/pci/drivers/${DRIVER}/debug_level
|
||||
|
||||
You can find the list of debug mask values in:
|
||||
drivers/net/wireless/mac80211/iwlwifi/iwl-debug.h
|
||||
|
||||
If this is your first time using this driver, you should say Y here

any problems you may encounter.

|
||||
information on the capabilities currently enabled in this

driver and for tips for debugging any issues or problems.
|

In order to use this driver, you will need a microcode (uCode)

If you want to compile the driver as a module ( = code which can be
|
||||
inserted in and remvoed from the running kernel whenever you want),
|

|

|

* #define that provides the caller's __LINE__ to the double prefix version.
|

*
|

* If you wish to call the function without any debug or state checking,

* you should use the single _ prefix version (as is used by dependent IO

* _iwl_read32.)
|

|

* These declarations are *extremely* useful in quickly isolating code deltas

* which result in misconfiguring of the hardware I/O. In combination with
|
||||
* git-bisect and the IO debug level you can quickly determine the specific
|

* commit which breaks the IO sequence to the hardware.

/**
|

* BSM (Bootstrap State Machine)
|
||||
*
|
||||
* The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
|
||||
* in special SRAM that does not power down when the embedded control
|
||||
* processor is sleeping (e.g. for periodic power-saving shutdowns of radio).
|
||||
*
|
||||
* When powering back up after sleeps (or during initial uCode load), the BSM
|
||||
* internally loads the short bootstrap program from the special SRAM into the
|
||||
* embedded processor's instruction SRAM, and starts the processor so it runs
|
||||
* the bootstrap program.
|
||||
*
|
||||
* This bootstrap program loads (via PCI busmaster DMA) instructions and data
|
||||
* images for a uCode program from host DRAM locations. The host driver
|
||||
* indicates DRAM locations and sizes for instruction and data images via the
|
||||
* four BSM_DRAM_* registers. Once the bootstrap program loads the new program,
|
||||
* the new program starts automatically.
|
||||
*
|
||||
* The uCode used for open-source drivers includes two programs:
|
||||
*
|
||||
* 1) Initialization -- performs hardware calibration and sets up some
|
||||
* internal data, then notifies host via "initialize alive" notification
|
||||
* (struct iwl_init_alive_resp) that it has completed all of its work.
|
||||
* After signal from host, it then loads and starts the runtime program.
|
||||
* The initialization program must be used when initially setting up the
|
||||
* NIC after loading the driver.
|
||||
*
|
||||
* 2) Runtime/Protocol -- performs all normal runtime operations. This
|
||||
* notifies host via "alive" notification (struct iwl_alive_resp) that it
|
||||
* is ready to be used.
|
||||
*
|
||||
* When initializing the NIC, the host driver does the following procedure:
|
||||
*
|
||||
* 1) Load bootstrap program (instructions only, no data image for bootstrap)
|
||||
* into bootstrap memory. Use dword writes starting at BSM_SRAM_LOWER_BOUND
|
||||
*
|
||||
* 2) Point (via BSM_DRAM_*) to the "initialize" uCode data and instruction
|
||||
* images in host DRAM.
|
||||
*
|
||||
* 3) Set up BSM to copy from BSM SRAM into uCode instruction SRAM when asked:
|
||||
* BSM_WR_MEM_SRC_REG = 0
|
||||
* BSM_WR_MEM_DST_REG = RTC_INST_LOWER_BOUND
|
||||
* BSM_WR_MEM_DWCOUNT_REG = # dwords in bootstrap instruction image
|
||||
*
|
||||
* 4) Load bootstrap into instruction SRAM:
|
||||
* BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START
|
||||
*
|
||||
* 5) Wait for load completion:
|
||||
* Poll BSM_WR_CTRL_REG for BSM_WR_CTRL_REG_BIT_START = 0
|
||||
*
|
||||
* 6) Enable future boot loads whenever NIC's power management triggers it:
|
||||
* BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START_EN
|
||||
*
|
||||
* 7) Start the NIC by removing all reset bits:
|
||||
* CSR_RESET = 0
|
||||
*
|
||||
* The bootstrap uCode (already in instruction SRAM) loads initialization
|
||||
* uCode. Initialization uCode performs data initialization, sends
|
||||
* "initialize alive" notification to host, and waits for a signal from
|
||||
* host to load runtime code.
|
||||
*
|
||||
* 4) Point (via BSM_DRAM_*) to the "runtime" uCode data and instruction
|
||||
* images in host DRAM. The last register loaded must be the instruction
|
||||
* bytecount register ("1" in MSbit tells initialization uCode to load
|
||||
* the runtime uCode):
|
||||
* BSM_DRAM_INST_BYTECOUNT_REG = bytecount | BSM_DRAM_INST_LOAD
|
||||
*
|
||||
* 5) Wait for "alive" notification, then issue normal runtime commands.
|
||||
*
|
||||
* Data caching during power-downs:
|
||||
*
|
||||
* Just before the embedded controller powers down (e.g for automatic
|
||||
* power-saving modes, or for RFKILL), uCode stores (via PCI busmaster DMA)
|
||||
* a current snapshot of the embedded processor's data SRAM into host DRAM.
|
||||
* This caches the data while the embedded processor's memory is powered down.
|
||||
* Location and size are controlled by BSM_DRAM_DATA_* registers.
|
||||
*
|
||||
* NOTE: Instruction SRAM does not need to be saved, since that doesn't
|
||||
* change during operation; the original image (from uCode distribution
|
||||
* file) can be used for reload.
|
||||
*
|
||||
* When powering back up, the BSM loads the bootstrap program. Bootstrap looks
|
||||
* at the BSM_DRAM_* registers, which now point to the runtime instruction
|
||||
* image and the cached (modified) runtime data (*not* the initialization
|
||||
* uCode). Bootstrap reloads these runtime images into SRAM, and restarts the
|
||||
* uCode from where it left off before the power-down.
|
||||
*
|
||||
* NOTE: Initialization uCode does *not* run as part of the save/restore
|
||||
* procedure.
|
||||
*
|
||||
* This save/restore method is mostly for autonomous power management during
|
||||
* normal operation (result of POWER_TABLE_CMD). Platform suspend/resume and
|
||||
* RFKILL should use complete restarts (with total re-initialization) of uCode,
|
||||
* allowing total shutdown (including BSM memory).
|
||||
*
|
||||
* Note that, during normal operation, the host DRAM that held the initial
|
||||
* startup data for the runtime code is now being used as a backup data cache
|
||||
* for modified data! If you need to completely re-initialize the NIC, make
|
||||
* sure that you use the runtime data image from the uCode distribution file,
|
||||
* not the modified/saved runtime data. You may want to store a separate
|
||||
* "clean" runtime data image in DRAM to avoid disk reads of distribution file.
