Jesse.Zhang 124ffa2970 drm/amdgpu: Update SDMA firmware version check for user queue support
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.

Alex Deucher 38b20968f3 drm/amdgpu: move scheduler wqueue handling into callbacks
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.

Alex Deucher fb20954c97 drm/amdgpu/userq: rework driver parameter
Replace disable_kq parameter with user_queue parameter.
The parameter has the following logic:
 -1 = auto (ASIC specific default)
  0 = user queues disabled
  1 = user queues enabled and kernel queues enabled (if supported)
  2 = user queues enabled and kernel queues disabled

The default behavior (-1) is currently the same as 0 for current
ASICs.  To enable user queues (in addition to kernel queues) set
user_queue=1. To enable user queues and disable kernel queues
(to make all resources available to user queues), set user_queue=2.
