drm/amdgpu: properly handle GC vs MM in amdgpu_vmid_mgr_init()
When kernel queues are disabled, all GC vmids are available for the scheduler. MM vmids are still managed by the driver so make all 16 available. Also fix gmc 10 vs 11 mix up in commit 1f61fc28b939 ("drm/amdgpu/mes: make more vmids available when disable_kq=1") v2: Properly handle pre-GC 10 hardware Fixes: 1f61fc28b939 ("drm/amdgpu/mes: make more vmids available when disable_kq=1") Cc: Arvind Yadav <[email protected]> Reviewed-by: Arvind Yadav <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
