c4d4c1c66b drm/i915: Flush the freed object queue on device release 
As dmabufs may live beyond the PCI device removal, we need to flush the
freed object worker on device release, and include a warning in case
there is a leak.

94d4a2a9ae drm/i915: Unbind any residual objects/vma from the Global GTT on shutdown 
We may unload the PCI device before all users (such as dma-buf) are
completely shutdown. This may leave VMA in the global GTT which we want
to revoke, whilst keeping the objects themselves around to service the
dma-buf.

cad3688ff0 drm/i915: Split device release from unload 
We may need to keep our memory management alive after we have unloaded
the physical pci device. For example, if we have exported an object via
dmabuf, that will keep the device around but the pci device may be
removed before the dmabuf itself is released, use of the pci hardware
will be revoked, but the memory and object management needs to persist
for the dmabuf.

317eaa9508 drm/i915/debugfs: Add i915_hpd_storm_ctl 
This adds a file in i915's debugfs directory that allows userspace to
manually control HPD storm detection. This is mainly for hotplugging
tests, where we might want to test HPD storm functionality or disable
storm detection to speed up hotplugging tests without breaking anything.

Changes since v1:
- Make HPD storm interval configurable
- Misc code cleanup

d158694f45 drm/i915: Avoid spurious WARNs about the wrong pipe in the PPS code 
Until recently vlv_steal_power_sequencer() wasn't being called for
normal DP ports, and hence it could assert that it should only be
called for pipe A and B (since pipe C doesn't support eDP). However
that changed when we started to consider normal DP ports as well when
choosing a PPS. So we will now get spurious warnings when
vlv_steal_power_sequencer() does get called for pipe C. Avoid this by
moving the WARN down into vlv_detach_power_sequencer() where this
assertion should still hold.

72b72ae473 drm/i915: Always pin contexts into the high GGTT 
Now that we have fast top-down insertion into the drm_mm, we can use it
for frequent runtime operations like insertion of the context object,
whereas before we limited it to the one-off insertion of the pinned
kernel context. Keeping the active context objects out of the mappable
region of the global GTT (except under memory pressure) improves our
ability to allocate mappable aperture region without triggering a GPU
stall.

949e8ab3a9 drm/i915: Use the size/type of address space to make decisions 
Once the address space has been created (using 3 or 4 levels of page
tables), we should use that to program the appropriate type into the
contexts. This gives us the flexibility to handle different types of
address spaces at runtime.

fad061270a drm/amdgpu: report the number of bytes moved at buffer creation 
Like ttm_bo_validate(), ttm_bo_init() might need to move BO and
the number of bytes moved by TTM should be reported. This can help
the throttle buffer migration mechanism to make a better decision.

38fc4856ad drm/amdgpu: fix a potential deadlock in amdgpu_bo_create_restricted() 
When ttm_bo_init() fails, the reservation mutex should be unlocked.

In debug build, the kernel reported "possible recursive locking
detected" in this codepath. For debugging purposes, I also added
a "WARN_ON(ww_mutex_is_locked())" when ttm_bo_init() fails and the
mutex was locked as expected.

This should fix (random) GPU hangs. The easy way to reproduce the
issue is to change the "Super Sampling" option from 1.0 to 2.0 in
Hitman. It will create a huge buffer, evict a bunch of buffers
(around ~5k) and deadlock.

This regression has been introduced pretty recently.

8d2b47dde8 drm/i915: Enable atomic support by default on supported platforms. 
i915 is pretty much feature complete. Support for atomic i915-specific
connector properties is still missing; those properties can (for now)
only be set through the legacy ioctl.

ILK style watermarks and gen9+ watermarks are handled atomically,
and nonblocking modesets work. FBC has also been made to work with
atomic.

gen4x- and vlv/chv watermarks still need to be fixed, so disable atomic
by default there for now.

Flip the switch!!
