Subject: [PATCH 0/3] Thermal: Fix thermal zone update problems during bootup/suspend
Date: Sun, 27 Sep 2015 13:48:18 +0800 [thread overview]
Message-ID: <1443332898-13908-1-git-send-email-yu.c.chen@intel.com> (raw)
This patch set is to fix a series of thermal issues during system
bootup and suspend/resume. Two major reasons for these bugs are:
1.thermal core is unaware of suspending process, and uses the invalid
value cached after resuming, which brings the problems.
(PATCH 1/3 and 2/3]
2.thermal core forgets to update the device's status in some situations,
this may lead to unexpected behavior after system bootup.
[PATCH 3/3]
Please refer to:
https://bugzilla.kernel.org/show_bug.cgi?id=78201
for why these patches are proposed.
Chen Yu (3):
Thermal: initialize thermal zone device correctly
Thermal: handle thermal zone device properly during system sleep
Thermal: do thermal zone update after a cooling device registered
