Bug ID: 103486
Summary: Tonga DC vblank_mode=0 not working as expected
fullscreen
Product: DRI
Version: DRI git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: adf.li...@gmail.com
R9285, I notice that on both drm-next-4.15-dc and amd-staging-drm-next, when
using DC, vblank_mode=0 works windowed but not properly full screen.
Tried forcing TearFree from auto to off no difference.
There is no tearing where it would be expected - but it's not like it's just
being ignored, a bench mark test will cap fps at 2X refresh rate rather than
1X.
Maybe this is expected?
It doesn't happen with a months older DC kernel I have and looking at DC
benches on Phoronix I don't see any fps cap.
