2025-06-18drm/amdgpu: Use logical instance ID for SDMA v4_4_2 queue operationsJesse Zhang1-2/+2
Simplify SDMA v4_4_2 queue reset and stop operations by: 1. Removing GET_INST(SDMA0) conversion for ring->me 2. Using the logical instance ID (ring->me) directly 3. Maintaining consistent behavior with other SDMA queue operations This change aligns with the existing queue handling logic where ring->me already represents the correct instance identifier.

2025-06-18drm/amdgpu: Fix SDMA engine reset with logical instance IDJesse Zhang1-4/+6
This commit makes the following improvements to SDMA engine reset handling: 1. Clarifies in the function documentation that instance_id refers to a logical ID 2. Adds conversion from logical to physical instance ID before performing reset using GET_INST(SDMA0, instance_id) macro 3. Improves error messaging to indicate when a logical instance reset fails 4. Adds better code organization with blank lines for readability The change ensures proper SDMA engine reset by using the correct physical instance ID while maintaining the logical ID interface for callers.

2025-06-18drm/amdgpu: Suspend IH during mode-2 resetLijo Lazar1-4/+29
On multi-aid SOCs, there could be a continuous stream of interrupts from GC after poison consumption. Suspend IH to disable them before doing mode-2 reset. This avoids conflicts in hardware accesses during interrupt handlers while a reset is ongoing.

2025-06-18drm/amd/display: Destroy cached state in complete() callbackMario Limonciello1-40/+60
[Why] When the suspend sequence has been aborted after prepare() but before suspend() the resume() callback never gets called. The PM core will call complete() when this happens. As the state has been cached in prepare() it needs to be destroyed in complete() if it's still around. [How] Create a helper for destroying cached state and call it both in resume() and complete() callbacks. If resume has been called the state will be destroyed and it's a no-op for complete(). If resume hasn't been called (such as an aborted suspend) then destroy the state in complete().
