Subject: [PATCH v2 0/6] drm/rockchip: Some patches to update the PSR series
Date: Tue, 16 Aug 2016 18:11:10 -0700 [thread overview]
Message-ID: <1471396276-8222-1-git-send-email-seanpaul@chromium.org> (raw)
This is a follow-on set to Yakir's original PSR set here:
https://lkml.org/lkml/2016/7/24/34
and applies to the for-next branch at:
https://cgit.freedesktop.org/~seanpaul/dogwood
There are a few issues with the code that needed to be
shored up.
(1) The use of mutexes instead of spinlocks caused issues calling the
psr functions from vblank_enable/disable.
(2) The proliferation of workers due to (1)
(3) A bunch of races due to (2)
(4) vblank is not enabled unless an event is requested, this breaks
a lot of things, but most noticeable was cursor.
Changes in v2:
- Rebased on https://cgit.freedesktop.org/~seanpaul/dogwood
instead of random on-list patches (some of which had drifted)
- Added the "small fixes" patch to catch some nits
Sean Paul (6):
drm/rockchip: Convert psr_list_mutex to spinlock and use it
drm/rockchip: Don't use a delayed worker for psr state changes
drm/rockchip: Use a spinlock to protect psr state
drm/rockchip: A couple small fixes to psr
drm/rockchip: Improve analogix-dp psr handling
drm/rockchip: Enable vblank without event
