amdkfd_total_mem_size is the size of total GPUs vram plus system memory to estimate page tables memory usage and leave enough VRAM room for page tables allocation.

2022-10-06drm/amd/display: Update DCN321 hook that deals with pipe aquireRodrigo Siqueira1-1/+1
DCN provides a hook to check if we can have a new pipe allocation based on some DC constraints. If the current configuration supports the new pipe request, DC updates its context; otherwise, it will keep the same configuration. This behavior is similar across multiple ASICs, and for this reason, we reused DCN20 on DCN321. However, this DCN32x has some peculiarities which require its function to avoid weird pipe split issues. This commit update this issue by using dcn32_acquire_idle_pipe_for_head_pipe_in_layer instead of dcn20_acquire_idle_pipe_for_layer.

2022-10-06drm/amd/display: add dummy pstate workaround to dcn315Dmytro Laktyushkin4-69/+27
DCN315 has to always allow pstate change or SMU will hang. This workaround achieves this by applying a low pstate change latency to be used when pstate is calculated to be unsupported. This lower latency only accounts for memory retraining; a previous change handles locking in the highest available pstate allowing us to minimize required latency hiding to only account for memory retraining.

[WHY] Now dynamic ODM will now be disabled when MPO is required safe transitions to avoid underflow, but we are triggering the way of minimal transition too often. Commit state of dc with no check will do pipeline setup which may re-initialize the component with no need such as audio. [HOW] Just do the minimal transition when all of pipes are in use, otherwise return true to skip.
