drm/amdgpu: check alignment on CPU page for bo map

2021-04-07T13:00:10+00:00

commit e3512fb67093fabdf27af303066627b921ee9bd8 upstream. The page table of AMDGPU requires an alignment to CPU page so we should check ioctl parameters for it. Return -EINVAL if some parameter is unaligned to CPU page, instead of corrupt the page table sliently.

drm/amd/display: Add a backlight module option

2021-03-17T16:06:18+00:00

commit 7a46f05e5e163c00e41892e671294286e53fe15c upstream. There seem devices that don't work with the aux channel backlight control. For allowing such users to test with the other backlight control method, provide a new module option, aux_backlight, to specify enabling or disabling the aux backport support explicitly. As default, the aux support is detected by the hardware capability. v2: make the backlight option generic in case we add future backlight types (Alex) BugLink: https://bugzilla.opensuse.org/show_bug.cgi?id=1180749 BugLink: https://gitlab.freedesktop.org/drm/amd/-/issues/1438 Reviewed-by: Nicholas Kazlauskas Signed-off-by: Takashi Iwai Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: Add check to prevent IH overflow

2021-03-07T11:34:11+00:00

[ Upstream commit e4180c4253f3f2da09047f5139959227f5cf1173 ] Similar to commit ("drm/amdgpu: fix IH overflow on Vega10 v2"). When an ring buffer overflow happens the appropriate bit is set in the WPTR register which is also written back to memory. But clearing the bit in the WPTR doesn't trigger another memory writeback. So what can happen is that we end up processing the buffer overflow over and over again because the bit is never cleared. Resulting in a random system lockup because of an infinite loop in an interrupt handler. Reviewed-by: Christian König Signed-off-by: Defang Bo Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin
