CEA modes 6, 7, 8, 9, 21, 22, 23, 24, 44, 45, 50, 51, 54, 55, 58 and 59

The specification defines a VIC (Video Identification Code) for each
mode. When we're browsing drm_edid_modes.h, it really helps to have the
number available (otherwise we have to count...). These numbers are also
used in the EDID data (by the CEA-EXT extension block).

The CEA extension block has a field which describes which YCbCr modes are
supported by the device, use it to fill the drm_display_info color_formats

The code should obviously check the EDID feature field for EDID feature flags

git://people.freedesktop.org/~danvet/drm-intel into drm-core-next
Daniel Vetter wrote
First pull request for 3.5-next, slightly large than usual because new
things kept coming in since the last pull for 3.4.
Highlights:
- first batch of hw enablement for vlv (Jesse et al) and hsw (Eugeni). pci
ids are not yet added, and there's still quite a few patches to merge
(mostly modesetting). To make QA easier I've decided to merge this stuff
in pieces.
- loads of cleanups and prep patches spurred by the above. Especially vlv
is a real frankenstein chip, but also hsw is stretching our driver's
code design. Expect more to come in this area for 3.5.
- more gmbus fixes, cleanups and improvements by Daniel Kurtz. Again,
there are more patches needed (and some already queued up), but I wanted
to split this a bit for better testing.
- pwrite/pread rework and retuning. This series has been in the works for
a few months already and a lot of i-g-t tests have been created for it.
Now it's finally ready to be merged. Note that one patch in this series
touches include/pagemap.h, that patch is acked-by akpm.
- reduce mappable pressure and relocation throughput improvements from
Chris.
- mmap offset exhaustion mitigation by Chris Wilson.
- a start at figuring out which codepaths in our messy dri1/ums+gem/kms
driver we actually need to support by bailing out of unsupported case.
The driver now refuses to load without kms on gen6+ and disallows a few
ioctls that userspace never used in certain cases. More of this will
definitely come.
- More decoupling of global gtt and ppgtt.
- Improved dual-link lvds detection by Takashi Iwai.
- Shut up the compiler + plus fix the fallout (Ben)
- Inverted panel brightness handling (mostly Acer manages to break things
in this way).
- Small fixlets and adjustements and some minor things to help debugging.
Regression-wise QA reported quite a few issues on ivb, but all of them
turned out to be hw stability issues which are already fixed in
drm-intel-fixes (QA runs the nightly regression tests on -next alone,
without -fixes automatically merged in). There's still one issue open on
snb, it looks like occlusion query writes are not quite as cache coherent
as we've expected. With some of the pwrite adjustements we can now
reliably hit this. Kernel workaround for it is in the works."

On coherent systems (not-AGP) the IB should be in cached memory so should
be just as fast, so we can avoid copying to temporary pages and just use it
directly.

Ums is already disabled, but on ilk we can additionally disable gem
initialization when using user mode setting. Upstream never support
ilk without kernel modesetting and not even the RHEL ilk ums backport
needs gem - that driver is based on xf86-video-intel version 2.2,
which is pre-gem.

Spurred by an irc discussion, let's start to clear up which parts of
our kms + ums/gem + ums/dri1 + vbios/dri1 kernel driver pieces
userspace in the wild actually uses.
The idea is that we introduce checks at entry-points (module load
time, ioctls, ...) first and then reap any obviously dead code in a
second step.
As a first step refuse to load without kms on chips where userspace
never supported ums. Now upstream hasn't supported ums on ilk, ever.
But RHEL had the great idea to backport the kms support to their ums
driver.

vlv, ivb and snb all share the gen6+ gt irq handling. 3 copies of the
same stuff is a bit much, so extract it into a little helper.
Now ilk has a different gt irq handling than snb, but shares the same
irq handler (due to the similar display block). So also extract the
ilk gt irq handling to clearly separate these two things.
Nice side effect of this is that we can complete Ben Widawsky's gen6+
irq bit #define cleanup and call the render irq also with the GEN6
alias. Beforehand that code was shared with ilk, and neither option
really made much sense.
As a bonus this enables the error interrupt handling lifted from the
vlv code on snb and ivb, too.

Top-level interrupt bits are usually found in the display block. It
therefore makes sense to use HAS_PCH_SPLIT in i915_irq.c
But the irq stuff in intel_ring.c only concerns itself with render
core/gt-level interrupt sources. It therefore makes more sense to
switch based on gpu gen.
Kills a vlv special case.

We can now open-code the get/put irq functions as they were just
abstracting single register definitions.
It would be nice to merge this in with the IRQ handling code... but that
is too much work for me at present. In addition I could probably
collapse this in to a lot of the Ironlake stuff, but I don't think it's
worth the potential regressions.
This patch itself should not effect functionality.

- gen6 put/get only need one argument
rflags and gflags are always the same (see above explanation)
- remove a couple redundantly defined IRQs
- reordered some lines to make things go in descending order
Every ring has its own interrupts, enables, masks, and status bits that
are fed into the main interrupt enable/mask/status registers. At one
point in time it seemed like a good idea to make our functions support
the notion that each interrupt may have a different bit position in the
corresponding register (blitter parser error may be bit n in IMR, but
bit m in blitter IMR). It turned out though that the HW designers did us
a solid on Gen6+ and this unfortunate situation has been avoided. This
allows our interrupt code to be cleaned up a bit.
I jammed this into one commit because there should be no functional
change with this commit, and staging it into multiple commits was
unnecessarily artificial IMO.

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op. This leads to a
proliferation of the default_open() implementation across the entire

can replace all the users of this function with simple_open().

Pull drm update from Dave Airlie:
"This pull just contains a forward of the Intel fixes from Daniel.
The only annoyance is the RC6 enable, which really should have made
-next, but since Ubuntu are shipping it I reckon its getting a good
testing now by the time 3.4 comes out.
The pull from Daniel contains his pull message to me:
"A few patches for 3.4, major part is 3 regression fixes:
- ppgtt broke hibernate on snb/ivb. Somehow our QA claims that it
still works, which is why this has not been caught earlier.
- ppgtt flails in combination with dmar. I kinda expected this one :(
- fence handling bugfix for gen2/3. Iirc this one is about a year
old, fix curtesy Chris Wilson. I've created an shockingly simple
i-g-t test to catch this in the future."
Wrt regressions I've just got a report that gmbus (newly enabled
again in 3.4) is a bit noisy. I'm looking into this atm.
Also included are the rc6 enable patches for snb from Eugeni. I
wanted to include these in the main 3.4 pull but screwed it up.
Please hit me. Imo these kind of patches really should go in
before -rc1, but in thise case rc6 has brought us tons of press and
guinea pigs^W^W testers and ubuntu is already running with it. So
I estimate a pretty small chance for this to blow up.
And some smaller things:
- two minor locking snafus
- server gt2 ivb pciid
- 2 patches to sanitize the register state left behind by the bios
some more
- 2 new quirk entries
- cs readback trick against missed IRQs from ivb also enabled on snb
- sprite fix from Jesse"
Let's see if the "enable RC6 on sandybridge" finally works and sticks.
I've been enabling it by hand (i915.i915_enable_rc6=1) for several
months on my Macbook Air, and it definitely makes a difference (and has
worked for me). But every time we enabled it before it showed some odd
hw buglet for *somebody*.
This time it's all good, I'm sure.

Pull drm fixes from Dave Airlie:
"Mainly nouveau fixes, one for a regressions in -rc1, fixes for booting
on a ppc G5, and a Kconfig fix. Two radeon fixes, one oops, one s/r
fix. One udl mmap fix. And one core drm fix to stop bad fbdev apps
overwriting bits of ram."
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm: Validate requested virtual size against allocated fb size
drm/radeon: Don't dereference possibly-NULL pointer.
mm, drm/udl: fixup vma flags on mmap
drm/radeon/kms: fix fans after resume
nouveau/bios: Fix tracking of BIOS image data
nouveau: Fix crash when pci_ram_rom() returns a size of 0

mplayer -vo fbdev tries to create a screen that is twice as tall as the
allocated framebuffer for "doublebuffering". By default, and all in-tree
users, only sufficient memory is allocated and mapped to satisfy the
smallest framebuffer and the virtual size is no larger than the actual.
For these users, we should therefore reject any userspace request to
create a screen that requires a buffer larger than the framebuffer
originally allocated.
