2022-02-25drm/object: Add default color encoding and range value at resetDave Stevenson1-0/+14
The drm_plane_create_color_properties() function asks for an initial value for the color encoding and range, and will set the associated plane state variable with that value if a state is present. However, that function is usually called at a time where there's no state yet. Since the drm_plane_state reset helper doesn't take care of reading that value when it's called, it means that in most cases the initial value will be 0 (so DRM_COLOR_YCBCR_BT601 and DRM_COLOR_YCBCR_LIMITED_RANGE, respectively), or the drivers will have to work around it.

2022-02-25drm/msm: Avoid dirtyfb stalls on video mode displays (v2)Rob Clark10-33/+110
Someone on IRC once asked an innocent enough sounding question: Why with xf86-video-modesetting is es2gears limited at 120fps. So I broke out the perfetto tracing mesa MR and took a look. It turns out the problem was drm_atomic_helper_dirtyfb(), which would end up waiting for vblank.. es2gears would rapidly push two frames to Xorg, which would blit them to screen and in idle hook (I assume) call the DIRTYFB ioctl. Which in turn would do an atomic update to flush the dirty rects, which would stall until the next vblank. And then the whole process would repeat. But this is a bit silly, we only need dirtyfb for command mode DSI panels. So track in plane state whether dirtyfb is required, and track in the fb how many attached planes require dirtyfb so that we can skip it when not required. (Note, mdp4 does not actually have cmd mode support.)

2022-02-24drm/amdgpu: Exclude PCI reset method for now.Andrey Grodzovsky2-2/+7
According to my investigation of the state of PCI reset recently it's not working. The reason is due to the fact the kernel PCI code rejects SBR when there are more then one PF under same bridge which we always have (at least AUDIO PF but usually more) and that because SBR will reset all the PFS and devices under the same bridge as you and you cannot assume they support SBR. Once we anble FLR support we can reenable this option as FLR is doable on single PF and doens't have this restriction.
