Now that the user can opt-out of implicit fencing, we need to give them
back control over the fencing. We employ sync_file to wrap our
drm_i915_gem_request and provide an fd that userspace can merge with
other sync_file fds and pass back to the kernel to wait upon before
future execution.

Userspace is faced with a dilemma. The kernel requires implicit fencing
to manage resource usage (we always must wait for the GPU to finish
before releasing its PTE) and for third parties. However, userspace may
wish to avoid this serialisation if it is either using explicit fencing
between parties and wants more fine-grained access to buffers (e.g. it
may partition the buffer between uses and track fences on ranges rather
than the implicit fences tracking the whole object). It follows that
userspace needs a mechanism to avoid the kernel's serialisation on its
implicit fences before execbuf execution.
The next question is whether this is an object, execbuf or context flag.
Hybrid users (such as using explicit EGL_ANDROID_native_sync fencing on
shared winsys buffers, but implicit fencing on internal surfaces)
require a per-object level flag. Given that this flag need to be only
set once for the lifetime of the object, this reduces the convenience of
having an execbuf or context level flag (and avoids having multiple
pieces of uABI controlling the same feature).
Incorrect use of this flag will result in rendering corruption and GPU
hangs - but will not result in use-after-free or similar resource
tracking issues.
Serious caveat: write ordering is not strictly correct after setting
this flag on a render target on multiple engines. This affects all
subsequent GEM operations (execbuf, set-domain, pread) and shared
dma-buf operations. A fix is possible - but costly (both in terms of
further ABI changes and runtime overhead).

The i915_stolen_to_physical() function has 'unsigned long' as its
return type but it returns the 'base' variable, which is of type
'u32'. The only place where this function is called assigns the
returned value to dev_priv->mm.stolen_base, which is of type
'phys_addr_t'. The return value is actually a physical address and
everything else in the stolen memory code seems to be using
phys_addr_t, so fix i915_stolen_to_physical() to use phys_addr_t.

The intel_dp_autotest_video_pattern() function gets invoked through the
compliance test handler on a HPD short pulse if the test type is
set to DP_TEST_VIDEO_PATTERN. This performs the DPCD registers
reads to read the requested test pattern, video pattern resolution,
frame rate and bits per color value. The results of this analysis
are handed off to userspace so that the userspace app can set the
video pattern mode appropriately for the test result/response.
When the test is requested with specific BPC value, we read the BPC
value from the DPCD register. If this BPC value in intel_dp structure
has a non-zero value and we're on a display port connector, then we use
the value to calculate the bpp for the pipe. Also in this case if its
a 18bpp video pattern request, then we force the dithering on pipe to be
disabled since it causes CRC mismatches.
The compliance_test_active flag is set at the end of the individual
test handling functions. This is so that the kernel-side operations
can be completed without the risk of interruption from the userspace
app that is polling on that flag.

state, which can cause an immediate GPU hang for us. The only save
course of action is to reset the GPU prior to using it - similarly to
how we reset the GPU prior to unload (before a second user may be
affected by our leftover state).
We need to reset the GPU very early in our load/resume sequence so that
any stale HW pointers are revoked prior to any resource allocations we
make (that may conflict).

With these changes I feel confident enough to re-enable cursor updates.
Legacy cursor update won't block in the following cases:
- Moving cursor
- Changing cursor fb
The legacy cursor update will still block in the following cases:
- Showing/hiding cursor.
- Cursor size or scaling changes.
- cursor update while cursor is invisible (could be fixed, if it turns out to be important).
- Cursor tiling changes (Not sure we support tiled cursors.)
- Last update was a modeset.

Parameters tile_size, tile_width and tile_height were passed in the
wrong order to _intel_adjust_tile_offset() when calculating the rotated
offsets.
This doesn't fix any user visible bug, since for packed formats new
and old offset are the same and the rotated offsets are within a tile
before they are fed to _intel_adjust_tile_offset(). In that case, the
offsets are unchanged. That is not true for planar formats, but those
are currently not supported.

drm/i915: Split insertion/binding of an object into the VM
It is useful to have this trace as it pairs nicely with the vma_unbind
one to track vma activity.
Added inside the i915_vma_bind function (was outside before) to keep a
similar placement as trace_i915_vma_unbind.
v2: print bind_flags instead of flags (Chris)
