Using MOBFMT_RANGE in the early days of guest backed objects was a major
performance win but that has changed a lot since. There's no more
a performance reason to use MOBFMT_RANGE. The device can/will still
profit from the pages being contiguous but marking them as MOBFMT_RANGE
no longer matters.
Benchmarks (e.g. heaven, valley) show that creating page tables

The fb handle code assumes it deals with GEM objects. Because vmwgfx
buffer objects were not actually GEM objects we were not able to

we can trivially implement create_handle for buffer object backed

This is initial change adding support for DRIVER_GEM to vmwgfx. vmwgfx
was written before GEM and has always used TTM. Over the years the
TTM buffers started inherting from GEM objects but vmwgfx never
implemented GEM making it quite awkward. We were directly setting
variables in GEM objects to not make DRM crash.
This change brings vmwgfx inline with other DRM drivers and allows us
to use a lot of DRM helpers which have depended on drivers with GEM
support.
Due to historical reasons vmwgfx splits the idea of a buffer and surface
which makes it a littly tricky since either one can be used in most
of our ioctl's which take user space handles. For now our BO's are
GEM objects and our surfaces are opaque objects which are backed by
GEM objects. In the future I'd like to combine those into a single
BO but we don't want to break any of our existing ioctl's so it will
take time to do it in a non-destructive way.

vmwgfx shared very elaborate memory accounting with ttm. It was moved
from ttm to vmwgfx in change
f07069da6b ("drm/ttm: move memory accounting into vmwgfx v4")
but because of complexity it was hard to maintain. Some parts of the code
weren't freeing memory correctly and some were missing accounting all
together. While those would be fairly easy to fix the fundamental reason
for memory accounting in the driver was the ability to invoke shrinker
which is part of TTM code as well (with support for unified memory
hopefully coming soon).
That meant that vmwgfx had a lot of code that was either unused or
duplicating code from TTM. Removing this code also prevents excessive
calls to global swapout which were common during memory pressure
because both vmwgfx and TTM would invoke the shrinker when memory
usage reached half of RAM.

live_engine_busy_stats waits for busyness to start ticking before
sampling busyness for the test sample duration. The wait accesses an
MMIO register and the uncore call to read it takes up to 3 ms in the
worst case. This can result in the wait timing out since the MMIO read
itself consumes up the timeout of 500us. Increase the timeout to a
larger value of 10ms to account for the MMIO read time.

can only mark the *entire* page-table as operating in 64K GTT mode,
since the enable bit is still on the pde, and not the pte. And since we
we still need to allow 4K GTT pages for SMEM objects, we can't have a
"normal" 4K page-table with scratch pointing to LMEM, since that's
undefined from the hw pov. The simplest solution is to just move the 64K
scratch page to SMEM on such platforms and call it a day, since that

The upcoming privacy-screen support adds another check for
deferring probe till some other drivers have bound first.
Factor out the current vga_switcheroo_client_probe_defer() check
into an intel_modeset_probe_defer() helper, so that further
probe-deferral checks can be added there.

This reverts commit b3484d2b03.
That change attempted to improve the DRM drivers fbdev emulation device
names to avoid having confusing names like "simpledrmdrmfb" in /proc/fb.
But unfortunately, there are user-space programs such as pm-utils that
match against the fbdev names and so broke after the mentioned commit.
Since the names in /proc/fb are used by tools that consider it an uAPI,
let's restore the old names even when this lead to silly names like the
one mentioned above.

Add display/intel_display_trace.[ch] for defining display
tracepoints. The main goal is to reduce cross-includes between gem and
display. It would be possible split up tracing even further, but that
would lead to more boilerplate.
We end up having to include intel_crtc.h in a few places because it was
pulled in implicitly via intel_de.h -> i915_trace.h -> intel_crtc.h, and
that's no longer the case.
There should be no changes to tracepoints.
v3:
- Rebase
v2:
- Define TRACE_INCLUDE_PATH relative to define_trace.h (Chris)
- Remove useless comments (Ville)

[Why]
The HW interrupt gets disabled after S3/S4/reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.
[How]
Re-enable the interrupt after S3/S4/reset like we do for the other
DC interrupts.
Guard both instances of the outbox interrupt enable or we'll hang
during restore on ASIC that don't support it.
