Hi,

Some major GPUVM changes landed just before v8 of the PowerVR series. Since v8
went in rather quickly (review process was finished otherwise) I haven't had the
chance to review the subsequent code changes.

Hence, this series with a few fixes in this context. Plus a minor GPUVM patch to
make the drm_gpuvm_prepare_* helpers useful for PowerVR.

- Danilo

Changes in V2
=============
- GPUVM: update function DOC comment to indicate the passing zero fences to
  drm_gpuvm_prepare_* functions results into drm_exec_lock_obj() calls rather
  than drm_exec_prepare_obj() calls.
- pvr/vm: use drm_gpuvm_exec wrappers
- drop 3 patches which were applied already

Danilo Krummrich (2):
  drm/gpuvm: fall back to drm_exec_lock_obj()
  drm/imagination: vm: make use of GPUVM's drm_exec helper

This doesn't apply on drm-misc-next anymore, could you rebase and
resend?

Thanks!

I already applied the two patches to drm-misc-next.

Uh, sorry I didn't notice it.
