Add the IOCTL interface so that applications can allocate per VM BOs. Still WIP since not all corner cases are tested yet, but this reduces average CS overhead for 10K BOs from 21ms down to 48us. v2: add some extra checks, remove the WIP tag v3: rename new flag to AMDGPU_GEM_CREATE_VM_ALWAYS_VALID Signed-off-by:

Per VM BOs are handled like VM PDs and PTs. They are always valid and don't need to be specified in the BO lists. v2: validate PDs/PTs first Signed-off-by:

We need to refer to the parent instead of the root BO for multi level page tables on Vega10. Also don't set the PDE_PTE bit. v2: Don't set the PDE_PTE bit either. Signed-off-by:

We changed this to use an extra list a while back, but for the next series I need a separate flag again. v2: reorder to avoid unlocked list access Signed-off-by:

To allocate additional space for the dynamic cu masks. Confirmed with the hw team that we only need 1 dword for the mask. The mask is the same for each SE so you only need 1 dword. Reviewed-by:

Add 2 debugfs files, one that contains the VBIOS version, and one that contains the VBIOS itself. These won't change after initialization, so we can add the VBIOS version when we parse the atombios information. This ensures that we can find out the VBIOS version, even when the dmesg buffer fills up, and makes it easier to associate which VBIOS version is for which GPU on mGPU configurations. Set the size to 20 characters in case of some weird VBIOS version that exceeds the expected 17 character format (3-8-3\0). The VBIOS dump also allows for easy debugging v2: Move to debugfs, clarify commit message, add VBIOS dump file Signed-off-by: -
