[Why] A warning appears in the log on GPU reset for link_enc_cfg_link_encs_assign for the following condition: ASSERT(state->res_ctx.link_enc_cfg_ctx.link_enc_assignments[i].valid == false); This is not expected behavior and may result in link encoders being incorrectly assigned. [How] The dc->current_state is backed up into dm->cached_dc_state before we commit 0 streams. DC will clear link encoder assignments on the real state but the changes won't propagate over to the copy we made before the 0 streams commit. DC expects that link encoder assignments are *not* valid when committing a state, so as a workaround it needs to be cleared before passing it back into DC. Reviewed-by:

[Why] We're only setting the flags on stream[0]'s planes so this logic fails if we have more than one stream in the state. This can cause a page flip timeout with multiple displays in the configuration. [How] Index into the stream_status array using the stream index - it's a 1:1 mapping.

[Why] Dynamic link encoder assignment expects that it can modify DC current_state and the links associated with the incoming state when performing full validation. This does not align with our actual synchronization constraints in DM's atomic_check. [How] Since link encoder assignment only happens as part of full validation we can just use fast validation as part of atomic_check instead. This satisfy's DC interface requirements and skips the DML calculations needed for pipe programming - hopefully speeding up things a little bit to offset the cost of double validation during stream modification. We already do this as part of dc_commit_updates_for_stream() with validate_bandwidth(), so extend this to dc_commit_state() as well. Reviewed-by:

[Why] The HW interrupt gets disabled after GPU reset so we don't receive notifications for HPD or AUX from DMUB - leading to timeout and black screen with (or without) DPIA links connected.

amdgpu_connector_vga_get_modes missed function amdgpu_get_native_mode which assign amdgpu_encoder->native_mode with *preferred_mode result in amdgpu_encoder->native_mode.clock always be 0. That will cause amdgpu_connector_set_property returned early on: if ((rmx_type != DRM_MODE_SCALE_NONE) && (amdgpu_encoder->native_mode.clock == 0)) when we try to set scaling mode Full/Full aspect/Center. Add the missing function to amdgpu_connector_vga_get_mode can fix this. It also works on dvi connectors because amdgpu_connector_dvi_helper_funcs.get_mode use the same method. Signed-off-by:
