      iwlwifi: fix fw_restart module parameter · c04f9f22
      Wey-Yi Guy 提交于
      fw_restart module parameter was broken by the recent check for stuck
      queue patch, driver check the fx_restart module parameter
      before reload the firmware; but the stuck queue timer kick in after
      firmware error and reload the firmware even fw_restart=0. In this case,
      driver should not reload the firmware, it is important to help debugging
      uCode error.
      
      The only case we can ignore the module parameter is when user request
      firmware reload from debugfs, which can bypass the checking and perform
      firmware reload all the time.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      Revert "iwlwifi: Monitor and recover the aggregation TX flow failure" · ab9bdc34
      Reinette Chatre 提交于
      This reverts commit 1db5950f.
      
      The goal of "iwlwifi: Monitor and recover the aggregation TX flow failure"
      is to first detect when data transmission stalls and then to recover from
      this situation with a reset of the radio or the firmware, depending on how
      bad the transmission failures are.
      
      Unfortunately we have found that this change causes excessive resets with
      its current detection algorithm. It also performs its recovery action when
      none is really needed, like when we are not associated.
      
      Revert this change until the issues have been addressed.

      iwlwifi: cleanup spectrum measurement command support · 81963d68
      Reinette Chatre 提交于
      In iwlagn the support for spectrum measurement command has been
      disabled since v2.6.29 without any requests for it. In addition to this
      when this command is indeed enabled it has been found to trigger firmware
      SYSASSERT on at least 4965 and 5100 hardware (see
      http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1952 ). Since then
      this code has been bitrotting and cannot just be enabled without porting.
      
      Remove support for spectrum measurement command from iwlagn. It can be
      added back if there is a future need and the firmware problem it triggers
      has been fixed. Support for the spectrim measurement notification remains
      as it has been enabled all the time.
      
      In addition to this remove the 3945 spectrum measurement command Kconfig
      option and make this command always supported. The code added by this
      enabling is minimal and only run when user triggers a spectrum measurement
      request via sysfs.

      iwlwifi: Tune radio to prevent unexpected behavior · 3e4fb5fa
      Trieu 'Andrew' Nguyen 提交于
      We have seen the throughput dropped due to external noisy environment
      and the radio is out of tune.  There are lot of plcp errors indicating
      this condition. Eventually the station can get de-authenticated by the
      Access Point.  By resetting and tuning the radio, the plcp errors are
      reduced or eliminated and the throughput starts to rise.
      
      To prevent unexpected behavior such as drop in throughput or deauthentication,
      - The change provides the driver feature to monitor and tune the radio base on
      the statistics notification from the uCode.
      - It also allows the setting of the plcp error rate threshold via
      the plcp_delta under debugfs interface.
