drm/i915: add SW tracking to FBC enabling
Currently, calling intel_fbc_enabled() will trigger a register read.
And we call it a lot of times, even when FBC is disabled, so saving a
few cycles would be a good thing.
Another reason for this patch is because we currently call
intel_fbc_enabled() while the HW is runtime suspended, so the read
makes no sense and triggers a WARN. This happens even if FBC is
disabled by default. Of course one could argue that we just shouldn't
be calling intel_fbc_enabled() while the driver is runtime suspended,
and I agree that's a good argument, but I still think that the reason
explained in the first paragraph already justifies the patch.
This problem can easily be reproduced with many subtests of
igt/pm_rpm, and it is a regression introduced by:

It's good practice to use the more specific versions for irq save
spinlocks both as executable documentation and to enforce saner

context is unknown and there's a good reason to call a function from
all kinds of places.
This is the first step whice replaces all occurances of _irqsave in
process context with the simpler irq disable/enable variants. We don't
have any funky spinlock nesting going on, especially since the

However we already had vblank waits on the wrong side of

wait for the vblank like we should.
Move the drm_vblank_{on,off}() calls back out from
intel_crtc_{enable,disable}_planes() so that all of these vblank waits
return to proper operation. Also move the cxsr wait a bit earlier so
that we can keep the encoder disable after we've turned off vblanks.
Moving stuff out from the plane enable/disable functions seems
preferrable to moving the workaround stuff in since the workarounds are
required only on specific platforms.
While at it switch over to the drm_crtc_ variants of the vblank on/off
functions.

drm/i915: split intel_primary_plane_setplane() into check() and commit()
As a preparation for atomic updates we need to split the code to check
everything we are going to commit first. This patch starts the work to
split intel_primary_plane_setplane() into check() and commit() parts.
More work is expected on this to get a better split of the two steps.

gen6 and earlier conflate address space selection (ppgtt vs ggtt) with
the security bit (i.e. only privileged batches were allowed to run from
ggtt). From Haswell only, you are able to select the security bit
separate from the address space - and we always requested to use ppgtt.
This breaks the golden render state batch execution with full-ppgtt as
that is only present in the global GTT and more generally any secure
batch that is not colocated in the ppgtt and ggtt. So we need to
disable the use of the ppgtt selector bit for secure batches, or else we
hang immediately upon boot and thence after every GPU reset...

ignore the differentiation and always use secure==ggtt.

- various bits of roy's gt21x clock work
- various bits of kepler memory clock work (don't get too excited, there's at least one more major bit left that's busting higher freqs)
- misc fan control improvements
- kepler hdmi infoframe fixes
- dp audio
- l2 cache + cbc improvements

NVIDIA appear to have tweaked the algorithm from GF110, this implements
the previous algorithm for them still.

More accurate as to the function of the opcodes. Not only is FB disabled,
but the host is prevented from touching the GPU. An upcoming patch for
Kepler will also halt PFIFO (as NVIDIA does).

nv92 hardware has only 16 interrupt lines, while nv94 and later

PDISP setup. This is a regression introduced with
