[PATCH 1/2] drm/amdgpu: Clean up KFD VMID assignment
Felix Kuehling
Felix.Kuehling at amd.com
Thu Jun 25 03:18:33 UTC 2020
The KFD VMID assignment was hard-coded in a few places. Consolidate that in
a single variable adev->vm_manager.first_kfd_vmid. The value is still
assigned in gmc-ip-version-specific code.
