40ac948e02 drm/gt215/gr: fix initialisation on gddr5 boards
The binary driver modifies the default context to have this value, rather
than 0x3d0040, *after* it's filled the buffer with the usual golden data.

We don't really have anything in place to locate the correct offset to do
these type of modifications outside of the generation function, so this
will have to do.

178e561f51 drm/armada: convert to use vblank_on/off calls
A future commit changes the way various vblank calls behave, which
causes drivers to break.  Converting to use the drm_crtc_vblank_on/off
calls avoids this breakage.

c5488307dd drm/armada: fix page_flip refcounting leak
A refcounting leak was found of the original frame buffer attached to
the CRTC when using the page_flip ioctl, resulting in the frame buffer
never being freed.

This was not obvious initially, as if the page flip subsequently
re-attaches the original frame buffer, the refcounts will be balanced.
However, if the original frame buffer is freed, then it will be leaked.

Fix this by ensuring that we take a reference on the incoming fb, but
rely on the queued work to drop that ref count.

8e66e134e2 drm/radeon: fix vm page table block size calculation
The page offset is 12 bits.  For example if we have an
8 GB VM, we'd need 33 bits.  The number of bits needed
for PD + PT is 21 (33 - 12 or log2(8) + 18), not 20
(log2(8) + 17).

e300180f71 drm/ttm: Don't evict BOs outside of the requested placement range
The radeon driver uses placement range restrictions for several reasons,
in particular to make sure BOs in VRAM can be accessed by the CPU, e.g.
during a page fault.

Without this change, TTM could evict other BOs while trying to satisfy
the requested placement, even if the evicted BOs were outside of the
requested placement range. Doing so didn't free up any space in the
requested placement range, so the (potentially high) eviction cost was
incurred for no benefit.

Nominating for stable because radeon driver changes in 3.17 made this
much more noticeable than before.

e17ac6db2e drm/i915: Don't trust the DP_DETECT bit for eDP ports on CHV
On CHV the display DDC pins may be muxed to an alternate function if
there's no need for DDC on a specific port, which is the case for eDP
ports since there's no way to plug in a DP++ HDMI dongle.

This causes problems when trying to determine if the port is present
since the the DP_DETECTED bit is the latched state of the DDC SDA pin
at boot. If the DDC pins are muxed to an alternate function the bit
may indicate that the port isn't present.

To work around this look at the VBT as well as the DP_DETECTED bit
to determine if we should attempt registering an eDP port. Do this
only for ports B and C since port D doesn't support eDP (no PPS/BLC).

In theory someone could also wire up a normal DP port w/o DDC lines.
That would just mean that simple DP++ HDMI dongles wouldn't work
on such a port. With this change we would still fail to register
such DP ports. But let's hope no one wires their board in such a way,
and if they do we can extend the VBT checks to cover normal DP ports
as well.

dfda0df342 drm/mst: rework payload table allocation to conform better.
The old code has problems with the Dell MST monitors due to some
assumptions I made that weren't true.

I initially thought the Virtual Channel Payload IDs had to be in
the DPCD table in ascending order, however it appears that assumption
is bogus.

The old code also assumed it was possible to insert a member
into the table and it would move other members up, like it does
when you remove table entries, however reality has shown this
isn't true.

So the new code allocates VCPIs separate from entries in the payload
tracking table, and when we remove an entry from the DPCD table,
I shuffle the tracking payload entries around in the struct.

This appears to make VT switch more robust (still not perfect)
with an MST enabled Dell monitor.

673e7bbdb3 drm/i915: intel_backlight scale() math WA
Improper truncated integer division in the scale() function causes
actual_brightness != brightness. This (partial) work-around should be
sufficient for a majority of use-cases, but it is by no means a complete
solution.

TODO: Determine how best to scale "user" values to "hw" values, and
vice-versa, when the ranges are of different sizes. That would be a
buggy scenario even with this work-around.

The issue was introduced in the following (v3.17-rc1) commit:

    6dda730 drm/i915: respect the VBT minimum backlight brightness

Note that for easier backporting this commit adds a duplicated macro.
A follow-up cleanup patch rectifies this for 3.18+

macro

6fbb702e27 drm/nouveau: make sure display hardware is reinitialised on runtime resume
Linus commit 05c63c2ff2 modified the
runtime suspend/resume paths to skip over display-related tasks to
avoid locking issues on resume.

Unfortunately, this resulted in the display hardware being left in
a partially initialised state, preventing subsequent modesets from
completing.

This commit unifies the (many) suspend/resume paths, bringing back
display (and fbcon) handling in the runtime paths.

634ffcccfb drm/nouveau: punt fbcon resume out to a workqueue
Preparation for some runtime pm fixes.  Currently we skip over fbcon
suspend/resume in the runtime path, which causes issues on resume if
fbcon tries to write to the framebuffer before the BAR subdev has
been resumed to restore the BAR1 VM setup.

As we might be woken up via a sysfs connector, we are unable to call
fb_set_suspend() in the resume path as it could make its way down to
a modeset and cause all sorts of locking hilarity.

To solve this, we'll just delay the fbcon resume to a workqueue.

1dadba87cb drm/nouveau: nv84+: fix fence context seqno's
This fixes a regression introduced by "drm/nouveau: rework to new fence interface"
(commit 29ba89b237).

The fence sequence should not be reset after creation, the old value is used instead.
On destruction the final value is written, to prevent another source of accidental
wraparound in case of a channel being destroyed after a hang, and unblocking any other
channel that may wait on the about-to-be-deleted channel to signal.

I'm nothing if not optimistic about any hope of recovery from that. ;-)

77076c7aac ACPI / i915: Update the condition to ignore firmware backlight change request
Some of the Thinkpads' firmware will issue a backlight change request
through i915 operation region unconditionally on AC plug/unplug, the
backlight level used is arbitrary and thus should be ignored. This is
handled by commit 0b9f7d93ca (ACPI / i915: ignore firmware requests
for backlight change). Then there is a Dell laptop whose vendor backlight
interface also makes use of operation region to change backlight level
and with the above commit, that interface no long works. The condition
used to ignore the backlight change request from firmware is thus
changed to: if the vendor backlight interface is not in use and the ACPI
backlight interface is broken, we ignore the requests; oterwise, we keep
processing them.

e9681366ea drm/i915: Do not store the error pointer for a failed userptr registration
If we fail to create our mmu notification, we report the error back and
currently store the error inside the i915_mm_struct. This not only causes
subsequent registerations of the same mm to fail (an issue if the first
was interrupted by a signal and needed to be restarted) but also causes
us to eventually try and free the error pointer.

1b11629737 drm: Drop grab fpriv->fbs_lock in drm_fb_release
Paulo Zanoni reported a lockdep splat with a locking inversion between
fpriv->fbs_lock and the modeset locks. This issue was introduced in

commit f2b50c1161
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Fri Sep 12 17:07:32 2014 +0200

    drm: Fixup locking for universal cursor planes

This here is actually one of the rare cases where lockdep hits a false
positive: The deadlock only happens in drm_fb_release, which cleans up
the file private structure when all the references are gone. So the
locking is the very last one and no one else can deadlock. It also
doesn't protect anything at all, since all ioctls are guaranteed to
have returned at this point - otherwise they'd still hold a reference
on the file.

So let's just drop it and replace it with a big comment.

f2b50c1161 drm: Fixup locking for universal cursor planes
Bunch of things amiss:
- Updating crtc->cursor_x/y was done without any locking. Spotted by
  David Herrmann.
- Dereferencing crtc->cursor->fb was using the wrong lock, should take
  the crtc lock.
- Grabbing _all_ modeset locks torpedoes the reason why we added
  fine-grained locks originally: Cursor updates shouldn't stall on
  background stuff like probing outputs.

Best is to just grab the crtc lock around everything and drop all the
other locking. The only issue is that we can't switch planes between
crtcs with that, so make sure that never happens when someone uses
universal plane helpers. This shouldn't be a possible regression ever
since legacy ioctls also only grabbed the crtc lock, so switching
crtcs was never possible for the underlying plane object. And i915
(the only user of universal cursors thus far) has fixed cursor->crtc
links.

da8f43962b drm: Don't update vblank timestamp when the counter didn't change
If we already have a timestamp for the current vblank counter, don't
update it with a new timestmap. Small errors can creep in between two
timestamp queries for the same vblank count, which could be confusing to
userspace when it queries the timestamp for the same vblank sequence
number twice.

This problem gets exposed when the vblank disable timer is not used
(or is set to expire quickly) and thus we can get multiple vblank
disable<->enable transition during the same frame which would all
attempt to update the timestamp with the latest estimate.

The only user I could dig out was i915 back when ums+gem was still a
thing. But we've just very much killed that, and even when someone
screams about that we should resurrect that with a special hack
(wrapping drm_gem_mmap) in i915, not in the core code.

So good riddance to another entry point of the legacy buffer mapping
code.
