      iwlwifi: fix 3945 ucode info retrieval after failure · b7a79404
      Reinette Chatre authored
      
      
      When hardware or uCode problem occurs driver captures significant
      information from device to enable debugging. The format of this information
      is different between 3945 and 4965 and later devices, yet currently the
      3945 uses the 4965 and later format. Fix this by adding a new library call
      that is initialized to the correct formatting routine based on device.
      
      This moves the iwlagn event and error log handling back to iwl-agn.c to
      make it part of iwlagn module.
      
      Also remove the 3945 sysfs file that triggers dump of event log - there is
      already a debugfs file that can do it for all drivers.

      iwlwifi: automatically adjust sleep level · e312c24c
      Johannes Berg authored
      
      
      Depending on required latency requested by pm_qos (via mac80211)
      we can automatically adjust the sleep state. Also, mac80211 has
      a user-visible dynamic sleep feature where we are supposed to
      stay awake after sending/receiving frames to better receive
      response frames to our packets, this can be integrated into the
      sleep command.
      
      Currently, and this patch doesn't change that yet, we default
      to using sleep level 1 if PS is enabled. With a module parameter
      to iwlcore, automatic adjustment to changing network latency
      requirements can be enabled -- this isn't yet the default due
      to requiring more testing.
      
      The goal is to enable automatic adjustment and then go into the
      deepest possible sleep state possible depending on the networking
      latency requirements.
      
      This patch does, however, enable IEEE80211_HW_SUPPORTS_DYNAMIC_PS
      to avoid the double-timer (one in software and one in the device)
      when transmitting -- the exact timeout may be ignored but that is
      not of big concern.
      
      Note also that we keep the hard-coded power indices around for
      thermal throttling -- the specification of that calls for using
      the specified power levels. Those can also be selected in debugfs
      to allow easier testing of such parameters.

      iwlwifi: fix missing EXPORT_SYMBOL · 450ccb36
      Reinette Chatre authored
      
      
      When compiling without CONFIG_IWLWIFI_DEBUGFS there is a missing
      iwl_update_stats symbol. This is fixed by making this function an inline in
      the case when CONFIG_IWLWIFI_DEBUGFS is not set due to the hot path in
      which it is used.

      iwlwifi: refactor some thermal throttle code · 3ad3b92a
      Johannes Berg authored
      
      
      Some of the thermal throttle data structures and code
      are really very intermingled with the sleep (power)
      control code. They really do belong together in a way
      since the thermal throttle code uses powersaving to
      achieve its goal, but it's making it hard to work on
      the powersave code. Split this up to make that easier.
      I've also changed the antenna defines to an enum and
      used the same enum for RX and TX.

      iwlwifi: revert uCode Alive notification with timeout · c03ea162
      Reinette Chatre authored
      
      
      commit "iwlwifi: uCode Alive notification with timeout" introduced a more
      reliable mechanism for ucode loading. Unfortunately we hit a problem with
      it frequently enough to make a 4965 unusable. The problem can be seen in
      debug log below. What this code attempts is to set runtime ucode up to
      load, start a timer to wait for the alive response from runtime ucode, and
      if it times out it tries again. As can be seen below we receive the alive
      response and wake the waiting task _before_ the tasks starts waiting. The
      task thus times out as the alive response is not received while it is
      waiting for it and it restarts the device. This starts the cycle all over
      again.

      iwlwifi: Traffic type and counter for debugFs · 22fdf3c9

      Break down the traffic type and counter for both Tx and Rx.
      Enhance the tx_statistics and rx_statistics debugfs function and move
      to /sys/kernel/debug/ieee80211/phy0/iwlagn/debug directory to help
      better debugging both driver and uCode related problems.

      iwlwifi: new debugging feature for dumping data traffic · 20594eb0
      Wey-Yi Guy authored
      
      
      The traffic buffer will only beallocated and used if either bit 23
      (IWL_DX_TX) or bit 24 (IWL_DL_RX) of "debug" is set;
      example: "debug=0x800000" - log tx data traffic
               "debug=0x1000000" - log rx data traffic
               "debug=0x1800000" - log both tx and rx traffic
      
      The traffic log will store the beginning portion (64 bytes)  of the
      latest 256 of tx and rx packets in the round-robbin buffer for
      debugging,
      user can examine the log through debugfs file.
      
      How to display the current logged tx/rx traffic and txfifo and rxfifo
      read/write point:
      "cat traffic_log" in /sys/kernel/debug/ieee80211/phy0/iwlagn/debug
      directory
      
      By echo "0" to traffic_log file will empty the traffic log buffer and
      reset both tx and rx taffic log index to 0.
