[PATCH v9 3/4] drm/amdgpu: add debugfs support for VM pagetable per client

There is a newer version of this series
[PATCH v9 3/4] drm/amdgpu: add debugfs support for VM pagetable per client
Posted by Sunil Khatri 3 months, 1 week ago 
Add a debugfs file under the client directory which shares
the root page table base address of the VM.

This address could be used to dump the pagetable for debug
memory issues.

Move that into the caller of amdgpu_vm_init(), this way amdgpu_vm_init() also doesn't need to get the drm_file as parameter.

With that done Reviewed-by: Christian König <christian.koenig@amd.com>.

If nobody objects I will push the first two patches to drm-misc-next now, so you only need to edit, rebase and send out again patch #3 and #4.

Regards,
Christian
