[Why] PSR currently relies on the kernel's delayed vblank on/off mechanism as an implicit bufferring mechanism to prevent excessive entry/exit. Without this delay the user experience is impacted since it can take a few frames to enter/exit. [How] Only allow vblank disable immediate for DC when psr is not supported. Leave a TODO indicating that this support should be extended in the future to delay independent of the vblank interrupt. Fixes: 92020e81 ("drm/amdgpu/display: set vblank_disable_immediate for DC") Acked-by:

If xnack is on, VM retry fault interrupt send to IH ring1, and ring1 will be full quickly. IH cannot receive other interrupts, this causes deadlock if migrating buffer using sdma and waiting for sdma done while handling retry fault. Remove VMC from IH storm client, enable ring1 write pointer overflow, then IH will drop retry fault interrupts and be able to receive other interrupts while driver is handling retry fault. IH ring1 write pointer doesn't writeback to memory by IH, and ring1 write pointer recorded by self-irq is not updated, so always read the latest ring1 write pointer from register. Signed-off-by:

Fixes: 9f4f2c1a ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov") For sriov XGMI configuration, the host driver will handle the hive reset, so in guest side, the reset_sriov only be called once on one device. This will make kfd post_reset unblanced with kfd pre_reset since kfd pre_reset already been moved out of reset_sriov function. Move kfd post_reset out of reset_sriov function to make them balance .

[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] 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:
