      iwlwifi: fix uCode event tracing · 98d4bf0c
      Johannes Berg authored
      Fix multiple bugs in event tracing:
      
      1) If you enable uCode tracing with the device down,
         it will still attempt to access the device and
         continuously log "MAC is in deep sleep!" errors.
         Fix this by only starting logging when the device
         is actually alive.
      
      2) Now you can set the flag when the device is down,
         but logging doesn't happen when you bring it up.
         To fix that, start logging when the device comes
         alive. This means we don't log before -- we could
         do that but I don't need it right now.
      
      3) For some reason we read the error instead of the
         event log -- use the right pointer.
      
      4) Optimise SRAM reading of event log header.
      
      5) Fix reading write pointer == capacity, which can
         happen due to racy SRAM access
      
      6) Most importantly: fix an error where we would try
         to read WAY too many events (like 2^32-300) when
         we read the wrap counter before it is updated by
         the uCode -- this does happen in practice and will
         cause the driver to hang the machine.
      
      7) Finally, change the timer to 10ms instead of 100ms
         as 100ms is too slow to capture all data with a
         normal event log and with 100ms the log will wrap
         multiple times before we have a chance to read it.
