Enabling gfxoff quirk results in perfectly usable graphical user interface on MacBook Pro (15-inch, 2019) with Radeon Pro Vega 20 4 GB. Without the quirk, X server is completely unusable as every few seconds there is gpu reset due to ring gfx timeout. Signed-off-by:

[ 155.432975] snd_hda_intel 0000:63:00.1: CORB reset timeout#2, CORBRP = 65535 The offending commit is daf8de08 ("drm/amdgpu: always reset the asic in suspend (v2)"). Commit 34452ac3 ("drm/amdgpu: don't use BACO for reset in S3 ") doesn't help, so the issue is something different. Assuming that to make HDA resume to D0 fully realized, it needs to be successfully put to D3 first. And this guesswork proves working, by moving amdgpu_asic_reset() to noirq callback, so it's called after HDA function is in D3.

"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as documented in supported_modes of drm_plane_create_blend_mode_property(): https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c In this mode, both 'pixel alpha' and 'plane alpha' participate in the calculation, as described by the pixel blend mode formula in KMS/DRM documentation: out.rgb = plane_alpha * fg.rgb + (1 - (plane_alpha * fg.alpha)) * bg.rgb Considering the blend config mechanisms we have in the driver so far, the alpha mode that better fits this blend mode is the _PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain is the plane alpha (global_alpha). With this change, alpha property stops to be ignored. It also addresses Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734 v2: * keep the 8-bit value for global_alpha_value (Nicholas) * correct the logical ordering for combined global gain (Nicholas) * apply to dcn10 too (Nicholas) Signed-off-by:

Most firmware framebuffers have an underlying platform device, which can be hot-unplugged before loading the native graphics driver. OF framebuffers do not (yet) have that device. Fix the code by unregistering the framebuffer as before without a hot unplug. Tested with 5.17 on qemu ppc64le emulation. Signed-off-by:

[Why] DSC Power down code has been moved from dcn31_init_hw into init_pipes() Need to remove it from dcn10_init_hw() as well to avoid duplicated action on dcn1.x/2.x [How] Remove DSC power down code from dcn10_init_hw() Fixes: 8fa6f4c5 ("drm/amd/display: fixed the DSC power off sequence during Driver PnP") Reviewed-by:

[Why] Once DSC slice cannot fit pixel clock, we incorrectly reset min slices to 0 and allow max slice to operate, even when max slice itself cannot fit the pixel clock properly. [How] Change the sequence such that we correctly determine DSC is not possible when both min slices and max slices cannot fit pixel clock per slice. Reviewed-by:

MIPI-DSI devices, if they are controlled through the bus itself, have to be described as a child node of the controller they are attached to. Thus, there's no requirement on the controller having an OF-Graph output port to model the data stream: it's assumed that it would go from the parent to the child. However, some bridges controlled through the DSI bus still require an input OF-Graph port, thus requiring a controller with an OF-Graph output port. This prevents those bridges from being used with the controllers that do not have one without any particular reason to. Let's drop that requirement. Signed-off-by:

This commit corrects the printing of the IPU clock error percentage if it is between -0.1% to -0.9%. For example, if the pixel clock requested is 27.2 MHz but only 27.0 MHz can be achieved the deviation is -0.8%. But the fixed point math had a flaw and calculated error of 0.2%. Before: Clocks: IPU 270000000Hz DI 24716667Hz Needed 27200000Hz IPU clock can give 27000000 with divider 10, error 0.2% Want 27200000Hz IPU 270000000Hz DI 24716667Hz using IPU, 27000000Hz After: Clocks: IPU 270000000Hz DI 24716667Hz Needed 27200000Hz IPU clock can give 27000000 with divider 10, error -0.8% Want 27200000Hz IPU 270000000Hz DI 24716667Hz using IPU, 27000000Hz Signed-off-by:
