This is a follow-on set to Yakir's original PSR set here: https://lkml.org/lkml/2016/7/24/34 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) vblank is not enabled unless an event is requested, this breaks a lot of things, but most noticeable was cursor. ---------------------------------------------------------------------- Sean Paul (5): drm/rockchip: Change psr list mutex to spinlock drm/rockchip: Change state_mutex to spinlock drm/rockchip: Remove delayed work to enable/disable psr drm/rockchip: Improve analogix-dp psr handling drm/rockchip: Enable vblank without event drivers/gpu/drm/bridge/analogix/analogix_dp_core.c | 1 - drivers/gpu/drm/rockchip/analogix_dp-rockchip.c | 24 ++++--- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 2 +- drivers/gpu/drm/rockchip/rockchip_drm_drv.h | 2 +- drivers/gpu/drm/rockchip/rockchip_drm_psr.c | 84 ++++++++++++++-------- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 43 +++++------ 6 files changed, 90 insertions(+), 66 deletions(-) -- 2.8.0.rc3.226.g39d4020 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
