Since we're not synchronizing the ring request list during error state capture
the request list state might change between the time the corresponding error
request list was allocated and dimensioned to the time when the ring request
list is actually captured into the error state. If this happens then do an
early exit and be aware that the captured error state might not be fully
reliable.
* v2:
- Chris Wilson: Removed WARN_ON from size check since having the error state
request list and the live driver request list diverge like this is a
legitimate behaviour.
- Tomas Elf: Removed update of num_request field since this made no sense. Just
exit and move on.
* v3:
- Chris Wilson: Removed error message at the point of early exit. The user is
not interested in any state changes happening during the error state capture,
only in the state that we're trying to capture at the point of the error.

We get tons of cases where the master interrupt handler apparently set
a bit, with the SDEIIR disagreeing. No idea what's going on there, but
it's consistent on gen8+, no one seems to care about it and it's
making CI results flaky.
Shut it up.

In order to produce an image, the scalar needs to be fed extra
pixels. These top/bottom/left/right values depend on a various of
factors, including resolution, scaling type, phase step and
initial phase.
Pixel Extension are programmed by hardware in most targets - and
can be overwritten by software. For some targets (e.g.: msm8996),
software *must* program those registers.
In order to ease this computation, let's always use bilinear
filters, which are easier to program from kernel. Eventually,
all of these values will come down from user space for better
quality.

at. The kernel will then do its utmost to fit the object into that
location. The assumption is that userspace is handling its own object
locations (for example along with full-ppgtt) and that the kernel will
rarely have to make space for the user's requests.

The revert dance could use some explanation: we had stuff fixed in

drm/nouveau/gem: return only valid domain when there's only one
|
|
On nv50+, we restrict the valid domains to just the one where the buffer
was originally created. However after the buffer is evicted to system
memory, we might move it back to a different domain that was not
originally valid. When sharing the buffer and retrieving its GEM_INFO
data, we still want the domain that will be valid for this buffer in a
pushbuf, not the one where it currently happens to be.
This resolves fdo#92504 and several others. These are due to suspend
evicting all buffers, making it more likely that they temporarily end up
in the wrong place.

In Linux 4.3-rc5, there is an error case in drm_dp_get_branch_device
that returns without releasing mgr->lock, resulting a spew of kernel
messages about a kernel work function possibly having leaked a mutex
and presumably more serious adverse consequences later. This patch
changes the error to "goto out" to unlock the mutex before returning.

Calculate pipe watermarks during atomic calculation phase, based on the
contents of the atomic transaction's state structure. We still program
the watermarks at the same time we did before, but the computation now
happens much earlier.
While this patch isn't too exciting by itself, it paves the way for
future patches. The eventual goal (which will be realized in future
patches in this series) is to calculate multiple sets up watermark
values up front, and then program them at different times (pre- vs
post-vblank) on the platforms that need a two-step watermark update.
While we're at it, s/intel_compute_pipe_wm/ilk_compute_pipe_wm/ since
this function only applies to ILK-style watermarks and we have a
completely different function for SKL-style watermarks.
Note that the original code had a memcmp() in ilk_update_wm() to avoid
calling ilk_program_watermarks() if the watermarks hadn't changed. This
memcmp vanishes here, which means we may do some unnecessary result
generation and merging in cases where watermarks didn't change, but the
lower-level function ilk_write_wm_values already makes sure that we
don't actually try to program the watermark registers again.
v2: Squash a few commits from the original series together; no longer
leave pre-calculated wm's in a separate temporary structure since
it's easier to follow the logic if we just cut over to using the
pre-calculated values directly.
v3:
- Pass intel_crtc instead of drm_crtc to .compute_pipe_wm() entrypoint
and use intel_atomic_get_crtc_state() to avoid need for extra
casting. (Ander)
- Drop unused intel_check_crtc() function prototype. (Ander)

A future patch will calculate these during the atomic 'check' phase
rather than at WM programming time, so let's store the watermark

active on the hardware remains in intel_crtc.

values in a union.

The only platform that still has an update_sprite_wm entrypoint is SKL;
on SKL, intel_update_sprite_watermarks just updates intel_plane->wm and
then performs a regular watermark update. However intel_plane->wm is
only used to update a couple fields in intel_wm_config, and those fields
are never used by the SKL code, so on SKL an update_sprite_wm is
effectively identical to an update_wm call. Since we're already
ensuring that the regular intel_update_wm is called any time we'd try to
call intel_update_sprite_watermarks, the whole call is redundant and can
be dropped.

Determine whether we need to apply this workaround at atomic check time
and just set a flag that will be used by the main watermark update
routine.
Moving this workaround into the atomic framework reduces
ilk_update_sprite_wm() to just a standard watermark update, so drop it
completely and just ensure that ilk_update_wm() is called whenever a
sprite plane is updated in a way that would affect watermarks.

This commit addresses some stability problems with the command buffer
submission code recently introduced:
1) Make the vmw_cmdbuf_man_process() function handle reruns internally to
avoid losing interrupts if the caller forgets to rerun on -EAGAIN.
2) Handle default command buffer allocations using inline command buffers.
This avoids rare allocation deadlocks.
3) In case of command buffer errors we might lose fence submissions.
Therefore send a new fence after each command buffer error. This will help
avoid lengthy fence waits.
