BPP bits defined in VBT should be used only on panels whose
edid version is 1.3 or older. EDID version 1.4 introduced offsets
where bpp is defined and read into display_info, hence bpp from
VBT will be used only when bpc in display_info is zero.
v2: use display_info.bpc for deciding when to use vbt_bpp (Jani)

I was told that the "repurposed D1 definition" is still valid for SKL.
It is BDW that is special due to its hotplug bug, so let's

With this simple git diff command one can see that skl_init_workarounds()
got two copies of WaBarrierPerformanceFixDisable:skl:
git diff -U21 ca6e4405779e^1 ca6e4405779e drivers/gpu/drm/i915/intel_ringbuffer.c
This happened when the backmerge of drm-intel-fixes-2015-07-15
Merged the same fix on both sides. Same fix but not identical enough for
git: with a different surrounding context; hence the code duplication.
This commit merely reverts the output of the git command above
= the duplication introduced in the backmerge.
(This duplication was found while running git sanity checks on a
_linearized_ i915 forklift for ChromeOS.)

Since active function on VLV immediately activate PSR let's give more

count.

Underrun.
It is true that in a product we won't keep disabling and enabling planes so
frequently, but for safeness let's stay conservative.
It is also true that 500ms is an etternity. But PSR is anyway a power saving
feature for idle scenario. So if it is idle feature stays on and 500ms to get
it reanabled is not that insane.
v2: Rebase over intel_psr.c and fix typo.
v3: Revival: Manual tests indicated that this is needed. With a short delay
there is a huge risk of getting blank screens when planes are being enabled.
v4: Revival 2 with reasonable delay. 1/2 sec instead of 5. VBT is 10 sec but
actually time for link training what we aren't doing, but with only 100 sec
in some cases kms_psr_sink_crc manual was showing blank screen,
so let's use this for now. Also changed comment by a FIXME.
v5: Rebase after a long time, remove FIXME and update comment above.
v6: msecs_to_jiffies is already on delay. remove duplication.
v7: use msecs_to_jiffies on schedule_delayed_work call.

First, an introduction. We currently have two types of GTT mmaps: the
"normal" old mmap, and the WC mmap. For frontbuffer-related features
that have automatic hardware tracking, only the non-WC mmap writes are
detected by the hardware. Since inside the Kernel both are treated as
ORIGIN_GTT, any features ignoring ORIGIN_GTT because of the hardware
tracking are destined to fail.
One of the special rules defined for the WC mmaps is that the user
should call the dirtyfb IOCTL after he is done using the pointers, so
that results in an intel_fb_obj_flush() call. The problem is that the
dirtyfb is passing ORIGIN_GTT, so it is being ignored by FBC - even
though the hardware tracking is not detecing the WC mmap operations.
So in order to fix that without having to give up the automatic
hardware tracking for GTT mmaps we transform the flush operation from
dirtyfb into a special operation: ORIGIN_DIRTYFB.
This commit fixes all the kms_frontbuffer_tracking subtests that
contain "fbc" and "mmap-wc" in their names and are currently failing
(for a total of 16 subtests).

Use the appropriate call.
I know there's a discussion about whether we need this call here at
all, but removing the call means we'll only update FBC after we get
the page flip IRQ. So the user may only see the new frame a little
after it should. Let's wait just a little bit more before removing
this call since we can rely in the HW tracking for accurate flips.

Because intel_unpin_work_fn() already calls
intel_frontbuffer_flip_complete() which will call intel_fbc_flush()
which will call intel_fbc_update() when needed.
We couldn't fix this previously due to the fact that FBC was not
properly behaving as intended on frontbuffer flushes, but now that
this is fixed, we can remove the additional call.

Due to the way busy_bits was handled, we were not doing any flushes if
we didn't previously get an invalidate. Since it's possible to get
flushes without an invalidate first, remove the busy_bits early
return.
So now that we don't have the busy_bits guard anymore we'll need the
origin check for the GTT tracking (we were not doing anything on GTT
flushes due to the GTT check at invalidate()).
As a last detail, since we can get multiple consecutive flushes,
disable FBC before updating it, otherwise intel_fbc_update() will just
keep FBC enabled instead of restarting it.
Notice that this does not fix any of the current IGT tests due to the
fact that we still have a few intel_fbc() calls at points where we
also have the frontbuffer tracking calls: we didn't fully convert to
frontbuffer tracking yet. Once we remove those calls and start relying
only on the frontbuffer tracking infrastructure we'll need this patch.

When we shrink our working sets, we want to avoid stealing pages from
objects that likely to be reused in the near future. We first look at
inactive objects before processing active objects - but what about a
recently active object that is about to be used again. That object's
position in the bound_list is ordered by the time of binding, not the
time of last use, so the most recently used inactive object could well
be at the head of the shrink list. To compensate, give the object a bump
to MRU when it becomes inactive (thus transitioning to the end of the
first pass in shrink lists). Conversely, bumping on inactive makes
bumping on active useless, since when we do have to reap from the active
working set, everything is going to become inactive very quickly and the
order pretty much random - just hope for the best at that point, as once
we start stalling on active objects, we can hope that the rebinding
neatly orders vital objects.

Chris rightfully suggested that documenting fences without documenting
the BO tiling tracking doesn't make much sense, so fix that.
The important bit to stress here (since it lead to some confusion) is
the GEM doesn't really care about tiling. Except for a few select cases
where the kernel needs to manage something that userspace can't take
care of: Namely the limited number of fences and fixing up swizzling,
although we still fail at the later.
v2: Move the low-level tiling/swizzling functions and kerneldoc to
i915_gem_fence.c and leave only the userspace interface here.

The Golden batch carries 3D state at the beginning so that HW starts with
a known state. It is carried as a binary blob which is auto-generated from
source. The idea was it would be easier to maintain and keep the complexity
out of the kernel which makes sense as we don't really touch it. However if
you really need to update it then you need to update generator source and
keep the binary blob in sync with it.
There is a need to patch this in bxt to send one additional command to enable
a feature. A solution was to patch the binary data with some additional
data structures (included as part of auto-generator source) but it was
unnecessarily complicated.
Chris suggested the idea of having a secondary batch and execute two batch
buffers. It has clear advantages as we needn't touch the base golden batch,
can customize secondary/auxiliary batch depending on Gen and can be carried
in the driver with no dependencies.
This patch adds support for this auxiliary batch which is inserted at the
end of golden batch and is completely independent from it. Thanks to Mika
for the preliminary review.
v2: Strictly conform to the batch size requirements to cover Gen2 and
add comments to clarify overflow check in macro (Chris, Mika).

Fastboot should only downgrade a modeset if we have a match, not be
used to upgrade to a full modeset. Otherwise we can only use it in a
very restricted way: Initial modeset when the request mode is the
preferred one of the panel and there's still a pfit active. And that
only works because our mode_from_pipe_config fills in the wrong mode
(it takes the adjusted mode, not the requested one).
But we want fast modesets everywhere even after boot-up (especially
for testing, but not only there). Hence we need to be able to make any
modeset a fast one, which means we need to invert the logic and
optionally downgrade a modeset.
Note that this needs ->connector_changed split out from ->mode_changed
otherwise it's not going to work (because we might loose a modeset
because connectors changed but otherwise the config matches). As soon
as that's merged we can drop the i915.fastboot check from this code.
Also make sure that we don't accidentally clear any_ms and that we add
the planes for any kind of modeset.
Finally rename fastboot to fastset (yeah it's a silly name) since this
really isn't about booting all that much.

Currently we both set mode->private_flags to some value and also use
the pipe_config quirk. But since the pipe_config quirk isn't tied to
the lifetime of the mode object we need to check both.
Simplify this by only using mode.private_flags and stop using the
INHERITED_MODE quirk. Also for clarity add an explicit #define for
that driver priavete mode flag.
By using crtc_state->mode_changed we can also remove the recalc local
variable.

Now that we recompute the pipe config for all CRTCs that have changed
we don't have problems with stale configuration data for the global
pfit and can remove this hack. Yay!

Backmerge fixes since it's getting out of hand again with the massive
split due to atomic between -next and 4.2-rc. All the bugfixes in
4.2-rc are addressed already (by converting more towards atomic
instead of minimal duct-tape) so just always pick the version in next
for the conflicts in modeset code.
All the other conflicts are just adjacent lines changed.
Conflicts:
drivers/gpu/drm/i915/i915_drv.h
drivers/gpu/drm/i915/i915_gem_gtt.c
drivers/gpu/drm/i915/intel_display.c

[danvet: Squash in follow-up to also remove start_vbl_count from
intel_crtc->atomic and put it into the intel_crtc directly - it's not
precomputed state.]

We needed this originally for updating pagetables in plane commit
functions. But that's extracted into prepare/cleanup now. The other
issue was running updates when the pipe was off. That's also now
fixed.

Now that there's only a single path for all atomic updates we can call
intel_(pre/post)_plane_update from intel_atomic_commit directly. This
makes the intention more clear.
