drm/amdgpu: Update SDMA firmware version check for user queue support

2025-08-04T19:48:14+00:00

This commit fixes a firmware version check for enabling user queue support in SDMA v7.0. The previous version check (7836028) was incorrect and could lead to issues with PROTECTED_FENCE_SIGNAL commands causing register conflicts between MCU_DBG0 and MCU_DBG1.

Move the scheduler wqueue stopping and starting into the ring reset callbacks. On some IPs we have to reset an engine which may have multiple queues. Move the wqueue handling into the backend so we can handle them as needed based on the type of reset available. Reviewed-by: Christian König Signed-off-by: Alex Deucher
