Subject: [char-misc 0/4] mei: reset fix
Date: Wed, 8 Jan 2014 20:19:20 +0200 [thread overview]
Message-ID: <1389205164-13553-1-git-send-email-tomas.winkler@intel.com> (raw)
This series should address possible hiccup in
mei reset flow presenting itself as never ending
repetition of error line.
unexpected reset: dev_state = RESETTING
The patches make sure that stall watchdog doesn't jump in
prior to its time; second the reset flow won't recuse,
and at last it will allow no more than 3 consecutive resets
for misbehaving hardware.
Tomas Winkler (4):
mei: do not run reset flow from the interrupt thread
mei: use hbm idle state to prevent spurious resets
mei: revamp mei reset state machine
mei: limit the number of consecutive resets
