2022-01-07drm/amd/display: Don't reinitialize DMCUB on s0ix resumeNicholas Kazlauskas1-3/+27
[Why] PSP will suspend and resume DMCUB. Driver should just wait for DMCUB to finish the auto load before continuining instead of placing it into reset, wiping its firmware state and reinitializing. If we don't let DMCUB fully finish initializing for S0ix then some state will be lost and screen corruption can occur due to incorrect address translation. [How] Use dmub_srv callbacks to determine in DMCUB is running and wait for auto-load to complete before continuining. In S0ix DMCUB will be running and DAL fw so initialize will skip. In S3 DMCUB will not be running and we will do a full hardware init. In S3 DMCUB will be running but will not be DAL fw so we will also do a full hardware init.

2022-01-07drm/amd/display: unhard code link to phy idx mapping in dc link and clean upWenjing Liu5-90/+95
[why] 1. Current code hard codes link to PHY mapping in dc link level per asic per revision. This is not scalable. In long term the mapping will be obatined from DMUB and store in dc resource. 2. Depending on DCN revision and endpoint type, the definition of dio_output_idx dio_output_type and phy_idx are not consistent. We need to unify the meaning of these hardware indices across different system configuration. [how] 1. Temporarly move the hardcoded mapping to dc_resource level, which should have full awareness of asic specific configuration and add a TODO comment to move the mapping to DMUB. 2. populate dio_output_idx/phy_idx for all configuration, define usb4_enabled bit instead of dio_output_type as an external enum.

[why] There will be a series of re-arch changes in Link Resource Management. They are more and more muxable link resource objects and the resource is insufficient for a one to one allocation to all links created. Therefore a link resource sharing logic is required to determine which link should use certain link resource. This commit is the first one in this series that starts by defining a link resource struct, this struct will be available to all interfaces that need to perform link programming sequence. In later commits, we will granduately decouple link resource objects out of dc link. So instead of access a link resource from dc link. Current link's resource can be accessible through pipe_ctx->link_res during commit, or by calling dc_link_get_cur_link_res function with current link passed in after commit.

2021-12-28drm/amdgpu: fixup bad vram size on gmc v8Zongmin Zhou1-3/+10
Some boards(like RX550) seem to have garbage in the upper 16 bits of the vram size register. Check for this and clamp the size properly. Fixes boards reporting bogus amounts of vram. after add this patch,the maximum GPU VRAM size is 64GB, otherwise only 64GB vram size will be used.

2021-12-28drm/amd/display: Fix USB4 null pointer dereference in update_psp_stream_configNicholas Kazlauskas1-4/+1
[Why] A porting error on a previous patch left the block of code that causes the crash from a NULL pointer dereference. More specifically, we try to access link_enc before it's assigned in the USB4 case in the following assignment: config.dio_output_idx = link_enc->transmitter - TRANSMITTER_UNIPHY_A; [How] That assignment occurs later depending on the ASIC version. It's only needed on DCN31 and only after link_enc is already assigned.

2021-12-28drm/amdgpu: Send Message to SMU on aldebaran passthrough for sbr handlingsashank saye9-16/+28
For Aldebaran chip passthrough case we need to intimate SMU about special handling for SBR.On older chips we send LightSBR to SMU, enabling the same for Aldebaran. Slight difference, compared to previous chips, is on Aldebaran, SMU would do a heavy reset on SBR. Hence, the word Heavy instead of Light SBR is used for SMU to differentiate.
