2022-02-16drm/amd/display: Fix for dmub outbox notification enableMeenakshikumar Somasundaram
[Why] Currently driver enables dmub outbox notification before oubox ISR is registered. During boot scenario, sometimes dmub issues hpd outbox message before driver registers ISR and those messages are missed. [How] Enable dmub outbox notification after outbox ISR is registered. Also, restructured outbox enable code to call from dm layer and renamed APIs.

[Why] configure_dp_hpo_throttled_vcp_size() was missing promotion before, but it was covered by not calling the missing function hook in the old interface hpo_dp_link_encoder->funcs. Recent refactor replaces with new caller link_hwss->set_throttled_vcp_size which needs that hook, and that causes null ptr hang.

2021-10-19drm/amd/display: increase Z9 latency to workaround underflow in Z9Eric Yang
[Why] Z9 latency is higher than when we originally tuned the watermark parameters, causing underflow. Increasing the value until the latency issues is resolved.

2021-10-19drm/amd/display: Require immediate flip support for DCN3.1 planesNicholas Kazlauskas
[Why] Immediate flip can be enabled dynamically and has higher BW requirements when validating which voltage mode to use. If we validate when it's not set then potentially DCFCLK will be too low and we will underflow. [How] DM always requires support so always require it as part of DML input parameters. This can't be enabled unconditionally on older ASIC because it blocks some expected modes so only target DCN3.1 for now.
