2024-04-09drm/amdgpu: use vm_update_mode=0 as default in sriov for gfx10.3 onwardsDanijel Slivka
Apply this rule to all newer asics in sriov case. For asic with VF MMIO access protection avoid using CPU for VM table updates. CPU pagetable updates have issues with HDP flush as VF MMIO access protection blocks write to BIF_BX_DEV0_EPF0_VF0_HDP_MEM_COHERENCY_FLUSH_CNTL register during sriov runtime. Moved the check to amdgpu_device_init() to ensure it is done after amdgpu_device_ip_early_init() where the IP versions are discovered.

2024-04-09drm/amd/display: handle invalid connector indicesJoshua Aberback
[Why] The function to count the number of valid connectors does not guarantee that the first n indices are valid, only that there exist n valid indices. When invalid indices are present, this results in later valid connectors being missed, as processing would end after checking n indices.

2024-04-09drm/amd/display: FEC overhead should be checked once for mst slot numsHersen Wu
[Why] Mst slot nums equals to pbn / pbn_div. Today, pbn_div refers to dm_mst_get_pbn_divider -> dc_link_bandwidth_kbps. In dp_link_bandwidth_kbps, which includes effect of FEC overhead already. As result, we should not include effect of FEC overhead again while calculating pbn by kpbs_to_peak_pbn (stream_kbps). [How] Include FEC overhead within dp_link_bandwidth_kbps.

2024-03-27drm/amd/display: fix nonseamless transition from ODM + MPO to ODM + subvpWenjing Liu
[why] when ODM + MPO is used for all 4 available pipes. Pipe transition will be nonseamless. Phantom OTG master pipe reuses the secondary OPP head pipe. There is no possible seamless path to transit to the new state. The correct logic would be to reuse a secondary DPP pipe as the phantom OTG master pipe. This way we are able to first transit the minimal transtion state of new and then transit to new state seamlessly. current New (nonseamless) ________________________ ________________________ | plane0 slice0 stream0| | plane0 slice0 stream0| |DPP0----OPP0----OTG0----| |DPP0----OPP0----OTG0----| | plane1 | | | | plane0 slice1 | | |DPP2----| | | |DPP2----OPP2----| | | plane0 slice1 | | | plane0 slice0 stream1| |DPP1----OPP1----| | |DPP1----OPP1----OTG1----| | plane1 | | | plane0 slice1 | | |DPP3----| | |DPP3----OPP3----| | |________________________| |________________________| New (seamless) New (minimal transition) ________________________ ________________________ | plane0 slice0 stream0| | plane0 slice0 stream0| |DPP0----OPP0----OTG0----| |DPP0----OPP0----OTG0----| | plane0 slice1 | | | plane0 slice1 | | |DPP1----OPP1----| | |DPP1----OPP1----| | | plane0 slice0 stream1| |________________________| |DPP2----OPP2----OTG2----| | plane0 slice1 | | |DPP3----OPP3----| | |________________________| [how] Try to acquire free pipes used as secondary DPP pipes from current state before try to acquire any free pipes for new OTG master pipe.
