[ath9k-devel] [PATCH 0/6] ath10k: fixes

[Michal Kazior]

This includes 2 patches from my previous patchset
that had conflicts. It is now rebased and should
apply cleanly on the github master branch.

Michal Kazior (6):
  ath10k: embed HTC struct inside ath10k
  ath10k: embed HTT struct inside ath10k
  ath10k: improve locking
  ath10k: abort scan properly if wmi_scan_stop fails
  ath10k: wait for CE to drain when shutting down
  ath10k: add missing debug prints

[ath9k-devel] [PATCH 3/6] ath10k: improve locking

[Michal Kazior]

Add more lockdep asserts and a few conf_mutex
locks. It's better to be on the safe side.

[ath9k-devel] [PATCH 5/6] ath10k: wait for CE to drain when shutting down

[Michal Kazior]

ath10k_pci_process_ce() is used to process
completions. Only one thread can do that though.

If one thread starts handling completions then the
other one (i.e. possibly PCI shutdown) would exit
immediatelely and free up memory while completions
are being processed leading to corruption.

This looks like a hack to me. Wouldn't it be a better to fix make sure
that all threads/tasklets are stopped, for example with tasklet_kill()
and cancel_work_sync()? (And of course first making sure that we don't
fire new instances). That way we could be sure that there is no other
thread running while we shutdown.

Apparently I can't reproduce this bug anymore. I can't really locate 
where the other thread could be comming from. Maybe an interrupt? We 
don't unregister interrupt handlers at the point where the issue happens 
(we only stop CE interrupts via registers).

Perhaps we can drop this patch for now and look for a proper solution 
later on?
