Dhinakaran Pandiyan 3b765c0b76 drm/vblank: Data type fixes for 64-bit vblank sequences. ... drm_vblank_count() has an u32 type returning what is a 64-bit vblank count. The effect of this is when drm_wait_vblank_ioctl() tries to widen the user space requested vblank sequence using this clipped 32-bit count(when the value is >= 2^32) as reference, the requested sequence remains a 32-bit value and gets queued like that. However, the code that checks if the requested sequence has passed compares this against the 64-bit vblank count. With drm_vblank_count() returning all bits of the vblank count, update drm_crtc_accurate_vblank_count() so that drm_crtc_arm_vblank_event() queues the correct sequence. Otherwise, this leads to prolonged waits for a vblank sequence when the current count is >=2^32. Finally, fix drm_wait_one_vblank() too. v2: Commit message fix (Keith) Squash commits (Rodrigo) Fixes: 570e86963a ("drm: Widen vblank count to 64-bits [v3]") Cc: Keith Packard <keithp@keithp.com> Cc: Michel Dänzer <michel@daenzer.net> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Keith Packard <keithp@keithp.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180203051302.9974-1-dhinakaran.pandiyan@intel.com		2018-02-15 11:48:09 -08:00
