This adds a bunch of complexity which the media driver has never
actually used. The media driver does technically bond a balanced engine
to another engine but the balanced engine only has one engine in the
sibling set. This doesn't actually result in a virtual engine.

Our code analyzer reported a double free bug.
In gen8_preallocate_top_level_pdp, pde and pde->pt.base are allocated
via alloc_pd(vm) with one reference. If pin_pt_dma() failed, pde->pt.base
is freed by i915_gem_object_put() with a reference dropped. Then free_pd

Lakshmi, ah that's true, so no need to re-report the result. In any case
the failure of rev 1 on igt@gem_sync@basic-many-each was still unrelated
to those changes, so if you still see that occuring again it's good to
track it as a known issue.

On HP Fury G7 Workstations, graphics output is re-routed from Intel GFX
to discrete GFX after S3. This is not desirable, because userspace will
treat connected display as a new one, losing display settings.
The expected behavior is to let discrete GFX drives all external

When resetting CACHE_MODE registers, don't enable HiZ Raw Stall

when rendering any kind of 3D accelerated content.

PSF GV points are an additional factor that can limit the
bandwidth available to display, separate from the traditional
QGV points. Whereas traditional QGV points represent possible
memory clock frequencies, PSF GV points reflect possible
frequencies of the memory fabric.

Treat it the same as the fake local-memory stuff, where it is disabled

All userspace objects must be cleared when allocating the backing store,
before they are potentially visible to userspace. For now use simple
CPU based clearing to do this for device local-memory objects, note that
in the near future this will instead use the blitter engine.

For some internal device local-memory objects it would be useful to have
an option to CPU clear the pages upon gathering the backing store. Note
that this might be before the blitter is useable, which is the case for

With the upcoming gem_create_ext we want to be able create a "vanilla"
object upfront and pass that directly to the extensions, before actually
initialising the object. Functionally this should be the same expect we
now feed the object into the lower-level region specific init_object.
Add new extension to support setting an immutable-priority-list of
potential placements, at creation time.
If we use the normal gem_create or gem_create_ext without the
extensions/placements then we still get the old behaviour with only
placing the object in system memory.

Same old gem_create but with now with extensions support. This is needed
to support various upcoming usecases.

As kvmgt module contains all handling for VFIO/mdev, leaving mdev attribute
groups in gvt module caused dependency issue. Although it was there for possible
other hypervisor usage, that turns out never to be true. So this moves all mdev
handling into kvmgt module completely to resolve dependency
This reverts commit 07e543f4f9d116d6b4240644191dee6388ef4a85.
With all mdev handing moved to kvmgt module, only kvmgt should depend
on VFIO_MDEV. So revert this one.

For some reason the vfio_mdev shim mdev_driver has its own module and

A later patch deletes this driver entirely.

This is series #3 in part of a larger work that arose from the minor

It applies on top of Alex's current tree and requires the prior two

This series achieves the removal of vfio_mdev.c.
