git://anongit.freedesktop.org/git/drm-intel into drm-fixes
Just a few minor fixes. Important one is the execbuf async fix (aka
ANDROID_native_sync). There was another patch for a display coherency
corner case on APL, but we've random-walked in that space too much,
and the cherry-pick looked really invasive.

drm/i915: Disable EXEC_OBJECT_ASYNC when doing relocations
drm/i915: Hold struct_mutex for per-file stats in debugfs/i915_gem_object

If we write a relocation into the buffer, we require our own implicit
synchronisation added after the start of the execbuf, outside of the
user's control. As we may end up clflushing, or doing the patch itself
on the GPU, asynchronously we need to look at the implicit serialisation
on obj->resv and hence need to disable EXEC_OBJECT_ASYNC for this
object.
If the user does trigger a stall for relocations, we make sure the stall
is complete enough so that the batch is not submitted before we complete
those relocations.

Since we may track unfenced access (GPU access to the vma that
explicitly requires no fence), vma->last_fence may be set without any
attached fence (vma->fence) and so will not be flushed when we call
i915_vma_put_fence(). Since we stopped doing a full retire of the
activity trackers for unbind, we need to explicitly retire each tracker.

The hash table created during vmw_cmdbuf_res_man_create was
never freed. This causes memory leak in context creation.
Added the corresponding drm_ht_remove in vmw_cmdbuf_res_man_destroy.
Tested for memory leak by running piglit overnight and kernel
memory is not inflated which earlier was.

drm: Tighten locking in drm_mode_getconnector
I reordered the logic a bit in that IOCTL, but that broke userspace
since it'll get the new mode list, but not the new property values.
Fix that again.
v2: Fix up the error path handling when copy_to_user for the modes
failes (Dhinakaran).

Maarten and Ville noticed that we are enabling backlight via DP aux very
early in the modeset_init path via the intel_dp_aux_setup_backlight()
function, since commit e7156c833903 ("drm/i915: Add Backlight Control using
DPCD for eDP connectors (v9)"). Looks like all we need to do during
_setup_backlight() is read the current brightness state instead of
modifying it.
v2: Rewrote commit message.

If intel_crtc_disable_noatomic() were to ever get called during resume
we'd end up deadlocking since resume has its own acqcuire_ctx but
intel_crtc_disable_noatomic() still tries to use the
mode_config.acquire_ctx. Pass down the correct acquire ctx from the top.

I tried __GFP_NORETRY in the belief that __GFP_RECLAIM was effective. It
struggles with handling reclaim of our dirty buffers and relies on
reclaim via kswapd. As a result, a single pass of direct reclaim is
unreliable when i915 occupies the majority of available memory, and the
only means of effectively waiting on kswapd to amke progress is by not
setting the __GFP_NORETRY flag and lopping. That leaves us with the
dilemma of invoking the oomkiller instead of propagating the allocation
failure back to userspace where it can be handled more gracefully (one
hopes). In the future we may have __GFP_MAYFAIL to allow repeats up until
we genuinely run out of memory and the oomkiller would have been invoked.
Until then, let the oomkiller wreck havoc.
v2: Stop playing with side-effects of gfp flags and await __GFP_MAYFAIL
v3: Update comments that direct reclaim only appears to be ignoring our
dirty buffers!

Commit 24f8e00a8a2e ("drm/i915: Prefer to report ENOMEM rather than
incur the oom for gfx allocations") made the bold decision to try and
avoid the oomkiller by reporting -ENOMEM to userspace if our allocation
failed after attempting to free enough buffer objects. In short, it
appears we were giving up too easily (even before we start wondering if
one pass of reclaim is as strong as we would like). Part of the problem
is that if we only shrink just enough pages for our expected allocation,
the likelihood of those pages becoming available to us is less than 100%
To counter-act that we ask for twice the number of pages to be made
available. Furthermore, we allow the shrinker to pull pages from the
active list in later passes.
v2: Be a little more cautious in paging out gfx buffers, and leave that
to a more balanced approach from shrink_slab(). Important when combined
with "drm/i915: Start writeback from the shrinker" as anything shrunk is
immediately swapped out and so should be more conservative.

We need to keep track of the last location we ask the hw to read up to
(RING_TAIL) separately from our last write location into the ring, so
that in the event of a GPU reset we do not tell the HW to proceed into
a partially written request (which can happen if that request is waiting
for an external signal before being executed).

Current it's strictly checked if PVINFO version matches 1.0
for GVT-g i915 guest which doesn't help for compatibility at
all and forces GVT-g host can't extend PVINFO easily with version
bump for real compatibility check.
This fixes that to check minimal required PVINFO version instead.
v2:
- drop unneeded version macro
- use only major version for sanity check
v3:
- fix up PVInfo value with kernel type
- one indent fix

skl_check_plane_surface() already rotates the clipped plane source
coordinates to match the scanout direction because that's the way
the GTT mapping is set up. Thus we no longer need to rotate the
coordinates in the watermark code.
For cursors we use the non-clipped coordinates which are not rotated
appropriately, but that doesn't actually matter since cursors don't
even support 90/270 degree rotation.

Starting from commit b63a16f6cd89 ("drm/i915: Compute display surface
offset in the plane check hook for SKL+") we've already rotated the src
coordinates by 270 degrees by the time we check if a scaler is needed
or not, so we must not account for the rotation a second time.
Previously we did these steps in the opposite order and hence the
scaler check had to deal with rotation itself. The double rotation
handling causes us to enable a scaler pretty much every time 90/270
degree plane rotation is requested, leading to fuzzier fonts and whatnot.

According to the eLCDIF initialization steps listed in the MX6SX
Reference Manual the eLCDIF block reset is mandatory.
Without performing the eLCDIF reset the display shows garbage content
when the kernel boots.
In earlier tests this issue has not been observed because the bootloader
was previously showing a splash screen and the bootloader display driver
does properly implement the eLCDIF reset.
Add the eLCDIF reset to the driver, so that it can operate correctly
independently of the bootloader.
Tested on a imx6sx-sdb board.

The previous attempt at this had an issue with with num_clips > 1
because it would always end up using the coordinates of the last
clip while using width and height calculated from the bounding
box of all the clips.
So if the last clip happens to be not at the top-left corner of
the bounding box, the CPU blit operation would go out of bounds.
The original intent was to coalesce all the clips into one blit,
and to do that we need to also track the starting point of the
content buffer.

When vmw_gb_surface_define_ioctl() is called with an existing buffer,
we end up returning an uninitialized variable in the backup_handle.
The fix is to first initialize backup_handle to 0 just to be sure, and
second, when a user-provided buffer is found, we will use the
req->buffer_handle as the backup_handle.

The 'req->mip_levels' parameter in vmw_gb_surface_define_ioctl() is
a user-controlled 'uint32_t' value which is used as a loop count limit.
This can lead to a kernel lockup and DoS. Add check for 'req->mip_levels'.

The scanline counter is bonkers on VLV/CHV DSI. The scanline counter
increment is not lined up with the start of vblank like it is on
every other platform and output type. This causes problems for
both the vblank timestamping and atomic update vblank evasion.
On my FFRD8 machine at least, the scanline counter increment
happens about 1/3 of a scanline ahead of the start of vblank (which
is where all register latching happens still). That means we can't
trust the scanline counter to tell us whether we're in vblank or not
while we're on that particular line. In order to keep vblank
timestamping in working condition when called from the vblank irq,
we'll leave scanline_offset at one, which means that the entire
line containing the start of vblank is considered to be inside
the vblank.
For the vblank evasion we'll need to consider that entire line
to be bad, since we can't tell whether the registers already
got latched or not. And we can't actually use the start of vblank
interrupt to get us past that line as the interrupt would fire
too soon, and then we'd up waiting for the next start of vblank
instead. One way around that would using the frame start
interrupt instead since that wouldn't fire until the next
scanline, but that would require some bigger changes in the
interrupt code. So for simplicity we'll just poll until we get
past the bad line.

Fixes: 2c3a3f44dc13 ("drm/i915: Fix pages pin counting around swizzle quirk")
Fixes: 957870f93412 ("drm/i915: Split out i915_gem_object_set_tiling()")
