6fe4f14044 drm/i915/execbuffer: Reorder binding of objects to favour restrictions
As the mappable portion of the aperture is always a small subset at the
start of the GTT, it is allocated preferentially by drm_mm. This is
useful in case we ever need to map an object later. However, if you have
a large object that can consume the entire mappable region of the
GTT this prevents the batchbuffer from fitting and so causing an error.
Instead allocate all those that require a mapping up front in order to
improve the likelihood of finding sufficient space to bind them.

809b63349c drm/i915: If we hit OOM when allocating GTT pages, clear the aperture
Rather than evicting an object at random, which is unlikely to alleviate
the memory pressure sufficient to allow us to continue, zap the entire
aperture. That should give the system long enough to recover and reap
some pages from the evicted objects, forestalling the allocation error
for the new object.

Before releasing the lock in order to copy the relocation list from user

0a58705b2f drm/i915: Periodically flush the active lists and requests
In order to retire active buffers whilst no client is active, we need to

This is useful for servers that queue up some rendering and then go to

potentially making that memory available again much earlier.

d912640058 drm/i915/gtt: Unmap the PCI pages after unbinding them from the GTT
Dave Airlie spotted that his ILK laptop with DMAR enabled was generating
the occasional DMAR warning.

"The ordering in the previous code was to rewrite the GTT table before
unmapping the pages and that makes sense to me."

This is his stable patch ported to d-i-n.

Cleanup several aspects of the rc6 code:
  - misnamed intel_disable_clock_gating function (was only about rc6)
  - remove commented call to intel_disable_clock_gating
  - rc6 enabling code belongs in its own function (allows us to move the

b79d499022 drm/i915: support low power watermarks on Ironlake
This patch actually makes the watermark code even uglier (if that's
possible), but has the advantage of sharing code between SNB and ILK at
least.  Longer term we should refactor the watermark stuff into its own
file and clean it up now that we know how it's supposed to work.

Supporting WM2 on my Vaio reduced power consumption by around 0.5W, so
this patch is definitely worthwhile (though it also needs lots of test
coverage).

97aaf91073 drm/i915/sdvo: Defer detection of output capabilities until probing
Alex Fiestas reported an issue with his HDMI connector being misdetected
as DVI unless he had something connected upon boot. By moving the
decision as to whether to use HDMI or DVI encoding for the HDMI capable
output until we probe the monitor means that we should avoid sending a
HDMI signal to a DVI monitor and also correctly detect hardware like
Alex's.

However, to really determine what connector is soldered onto the wire we
need to inspect the VBT sdvo child devices - but can we trust it?

f5afcd3dd0 drm/i915/crt: Check for a analog monitor in case of DVI-I
Since Linux 2.6.36 the digital output on my system (855GME + DVI-I) is
not working any longer. The analog output is always activated
regardless of the type of monitor attached.

The culprit seems to be intel_crt_detect_ddc(), which returns true as
soon as an ACK from the EDID device is received. Obviously this
approach does not work with DVI-I where the analog and digital outputs
share a common DDC bus.

In a similar manner to the shared DDC wire, ala the "Mac Mini Hack", we
need an additional check to make sure that there really is an analog
device attached to the DDC.

56bec7c009 drm/radeon/kms: disable underscan by default
Lots of HDMI TVs overscan the incoming image by default.
The underscan option was added as a way to compensate for
that by underscanning the image so that the edges would
not be cut off on an overscanning TV.  However, the TV
provides no way of knowing whether it is overscanning or
not.  If the user has disabled overscan on their TV or has a
TV that does not overscan, you will get black bars around the
edges of your screen.  Prior to the patch we got complaints
and bug reports from users with overscanning TVs, now with
the patch, we get lots of complaints and bug reports from
users with non-overscanning TVs.  There's no good default,
but on average there have been more users complaining about
it being on by default than off, so change it to off.  This
will probably result in a new deluge of overscanning TV user
complaints.  There's no winning.

ed18a3603f drm/radeon/kms/ni: load default sclk/mclk/vddc at pm init

NI, so now we need to load the MC ucode in the driver and set
the default clocks once the ucode is loaded.
