[Why] psr_feature_enabled flag is dynamically updated, and sometimes when zstate allow status is determined the flag has not been set to true yet even on PSR enabled config, lid off/on is such a case, which will result in zstate disabled even though PSR is supported. [How] Check the supported PSR version and the PSR disable status instead. Tested-by:

[why] There is a change previously to disallow DM to set dp drive setings when stream is not present. The logic might not work well with DP PHY complaince scenario with a PHY test fixture attachment. We need to make the method allow DP link drive settings changes even without stream attached to it. [how] revert back to previous code in set drive setting function then add an empty link_resource structure, then assign link resource based on current link resource if link resource is allocated to the current pipe.

[Why/How] We need to handle cable capabilities for cables that support cable ID. The cable attributes are intersected with the verified link caps to determine appropriate max link rate. After determining cable attributes we update the DP receiver. Tested-by:

[Why] If the DPCD caps specifies a PSR version newer than PSR_VERSION_1 then we fallback to using PSR_VERSION_1 in amdgpu_dm_set_psr_caps. This gets overriden with the raw DPCD value in amdgpu_dm_link_setup_psr, which can result in DMCUB hanging if we pass in an unsupported PSR version number. [How] Fix the hang by using link->psr_settings.psr_version directly during amdgpu_dm_link_setup_psr. Tested-by:

[Why] Link encoders are created based on its engine ID. The position of a link encoder in an array could be null since it didn't be allocated. Current matching logic didn't consider this situation and could get null encoder. [How] To add null encoder check to make the matching logic can go to next to get a valid one. Tested-by:

[Why] Currently, when we're tentatively detecting link configuration under mst case, we will wrongly notify a none existing stream sink to drm layer. It's due to we'll call amdgpu_dm_update_connector_after_detect() within dm_helpers_read_local_edid() to update connector when we're still under tentative detection procedure. [How] dm_helpers_read_local_edid() was designed to do "read" only. Don't update drm connector status when we're still under detection process. Tested-by:

[why] This is internal to dc so we don't have to add a prefix to indicate it is dc link_hwss instead someone else link_hwss. Tested-by:
-
Wenjing Liu authored
[why] as we add more link_hwss we are making a generic way to determine which type of link_hwss we should use. Later on we may think of introduce a link policy layer. it could be a thin layer that decide the type of link_hwss we use. So instead of passing in link and link_res we can just pass in link_policy and swtich based on link_policy->get_link_hwss_type. Tested-by:

Wenjing Liu authored
[why] Current we have hundreds of if/else or switch statement to check encoder type in dc_link level. The reason is because depending on the type of encoder dc_link needs to perform similar programming task but with different encoder interfaces. The story is to abstract these interfaces so dc_link can just perform the programming task without knowing the detail of which encoder it's dealing with. Tested-by:

[why] dc_link_detect_helper has multiple purpose: 1. Detect link and local sink. 2. Verify link capability by performing detection link training. 3. Start mst topology discovery and if succeeded fails the current interface. This is difficult to maintain as item 2 has become more destructive to current dc state. The change is to decouple these sequences to its own functions. Eventually only item 2 is a destructive method and we will redesign this sequence with a more unified policy across different encoder types. Tested-by:

Some clients(e.g., kfd) query sclk/mclk through this function. As cyan skillfish doesn't support dpm, for sclk, set min/max to CYAN_SKILLFISH_SCLK_MIN/CYAN_SKILLFISH_SCLK_MAX(to maintain the existing logic).For others, set both min and max to current value. Before this patch: # /opt/rocm/opencl/bin/clinfo Max clock frequency: 0Mhz After this patch: # /opt/rocm/opencl/bin/clinfo Max clock frequency: 2000Mhz v2: - Maintain the existing min/max sclk logic.(Lijo) v3: - Avoid fetching metrics table twice.(Lijo) Signed-off-by:
