Subject: [PATCH 0138/1050] drm/radeon: Add ATC VMID<-->PASID functions to
kfd->kgd
This patch adds three new interfaces to kfd2kgd interface file of radeon.
The interfaces are:
- Check if a specific VMID has a valid PASID mapping
- Retrieve the PASID which is mapped to a specific VMID
- Issue a VMID invalidation request to the ATC
