2021-05-10drm/amd/display: Handle pixel format test requestIlya Bakoulin1-1/+18
[Why] Some DSC tests fail because stream pixel encoding does not change its value according to the type requested in the DPCD test params. [How] Set stream pixel encoding before updating DSC config and configuring the test pattern.

2021-05-10drm/amd/display: Fix clock table filling logicIlya Bakoulin2-39/+74
[Why] Currently, the code that fills the clock table can miss filling information about some of the higher voltage states advertised by the SMU. This, in turn, may cause some of the higher pixel clock modes (e.g. 8k60) to fail validation. [How] Fill the table with one entry per DCFCLK level instead of one entry per FCLK level. This is needed because the maximum FCLK does not necessarily need maximum voltage, whereas DCFCLK values from SMU cover the full voltage range.

2021-05-10drm/amdgpu: Use device specific BO size & stride check.Bas Nieuwenhuizen1-6/+175
The builtin size check isn't really the right thing for AMD modifiers due to a couple of reasons: 1) In the format structs we don't do set any of the tilesize / blocks etc. to avoid having format arrays per modifier/GPU 2) The pitch on the main plane is pixel_pitch * bytes_per_pixel even for tiled ... 3) The pitch for the DCC planes is really the pixel pitch of the main surface that would be covered by it ... Note that we only handle GFX9+ case but we do this after converting the implicit modifier to an explicit modifier, so on GFX9+ all framebuffers should be checked here. There is a TODO about DCC alignment, but it isn't worse than before and I'd need to dig a bunch into the specifics. Getting this out in a reasonable timeframe to make sure it gets the appropriate testing seemed more important. Finally as I've found that debugging addfb2 failures is a pita I was generous adding explicit error messages to every failure case.

[Why] When hardware need to be reset, driver need to reset stream objects but dc_resource_state_destruct function omit resetting stream_count. It will lead page fault if some logic will touch stream object. [How] Set stream_count to 0 when dc_resource_state_destruct.

[Why] Sometimes, such as sleep wake, the link->local sink pointer changed, but the dc_stream_state->sink pointer is not changed. The checking of timing_changed reports wrong result, lead to link tear down unexpected wrongly. [How] SST compare local sink, MST compare proper remote link.

2021-05-10drm/amd/display: Add audio support for DFP type of active branch is DP caseDale Zhao4-14/+21
[Why] Per DP spec, for active protocol convertor adaptor, DP source should enable audio for DFP type is DP, HDMI or DP++. Current is_dp_active_dongle() checking is not precise, which treat branch device default as active dongle. As a result, we will mistakenly disable audio for DFP type is DP case. [How] Make is_dp_active_dongle() checking more precise for active dongle types. Rename active diongle type as SST branch device in case confusion.

2021-05-10drm/amd/display: Support for DMUB AUXJude Shih13-65/+240
[WHY] To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes. [How] 1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd with DCN and sends reply back in an outbox1 message triggering an outbox1 interrupt to driver. 2) In existing driver implementation, AUX commands are processed synchronously by configuring DCN reg. But in DMUB AUX, driver sends an inbox1 message and waits for a conditional variable (CV) which will be signaled by outbox1 ISR. 3) DM will retrieve Outbox1 message and send back reply to upper layer and complete the AUX command Signed-off-by: Jude Shih <shenshih@amd.com> Reviewed-by: Hanghong Ma <Hanghong.Ma@amd.com> Reviewed-by: Nicholas Kazlauskas <Nicholas.Kazlauskas@amd.com> Acked-by: Wayne Lin <Wayne.Lin@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
