Just one patch to fix compile fail for CONFIG_ACPI=n. Figured I better
send this out quickly to minimize the broken build span. Otherwise no
bugfixes (besides some bdw stuff) anywhere in sight.

Dave Airlie ab0169bb5c Merge tag 'bdw-stage1-2013-11-08-v2' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
So here's the Broadwell pull request. From a kernel driver pov there's
two areas with big changes in Broadwell:
- Completely new enumerated interrupt bits. On the plus side it now looks
  fairly unform and sane.
- Completely new pagetable layout.

To ensure minimal impact on existing platforms we've refactored both the
irq and low-level gtt handling code a lot in anticipation of the bdw push.
So now bdw enabling in these areas just plugs in a bunch of vfuncs.

Otherwise it's all fairly harmless adjusting of switch cases and
if-ladders to shovel bdw into the right blocks. So minimized impact on
existing platforms. I've also merged the bdw-stage1 branch into our
-nightly integration branch for the past week to make sure we don't break
anything.

Note that there's still quite a flurry or patches floating around, but
I've figured I'll push this out. I plan to keep the bdw fixes separate
from my usual -fixes stream so that you can reject them easily in case it
still looks like too much churn. Also, bdw is for now hidden behind the
preliminary hw enabling module option. So there's no real pressure to get
follow-up patches all into 3.13.

Daniel Vetter 38d83c96a3 drm/i915: Wire up cpu fifo underrun reporting support for bdw
HW engineers have listened and given us again a real interrupt with
masking and status regs. Yay!

For consistency with other platforms call the #define FIFO_UNDERRUN.
Eventually we also might need to have some enable/disable functions
for bdw display interrupts, but for now open-coding seems to be good
enough.

Daniel Vetter 6d766f022a drm/i915: Wire up port A aux channel
Useful for dp aux to work better. Also stop enabling the port A
hotplug event - eDP panels are expected to fire that interupt and
we're not really ready to deal with them. This is consistent with how
we handle port A on ilk-hsw.

The more important bit is that we must delay the enabling of hotplug
interrupts until all the encoders are fully set up. But we need irq
support earlier than that, hence hotplug interrupts can only be
enabled in the ->hpd_irq_setup callback.

v2: Drop the _HOTPLUG, it isn't (Ville).

Daniel Vetter 30100f2bea drm/i915: Fix up the bdw pipe interrupt enable lists
- Pipe underrun can't just be enabled, we need some support code like
  on ilk-hsw to make this happen. So drop it for now.
- CRC error is a special mode of the CRC hardware that we don't use,
  so again drop it. Real CRC support for bdw will be added later.
- All the other error bits are about faults, so rename the #define and
  adjust the output.

v2: Use pipe_name as pointed out by Ville. Ville's comment was on a
previous patch, but it was easier to squash in here.

v2: forgot to git add bogus whitespace fix

v3: Update with workaround names.
Use for_each_pipe() and CHICKEN_PIPESL_1(pipe) macro (Ville)

Ben Widawsky e64c4a1b8a drm/i915/bdw: Disable semaphores
We've done insufficient testing on them thus far, so keep them disabled
until we do test.

v2: Use WARN when not enabling preliminary HW support as this should
only be disabled for that case.

v3: Rip out the now useless (and really noisy) DRM_INFO output.

Ben Widawsky 6edee7f3e7 drm/i915/bdw: Create a separate BDW rps enable
This is mostly what we have for HSW with the exceptions of:
no writes:
  GEN6_RC1_WAKE_RATE_LIMIT
  GEN6_RC6pp_WAKE_RATE_LIMIT
  GEN6_RC1e_THRESHOLD
  GEN6_RC6p_THRESHOLD
  GEN6_RC6pp_THRESHOLD

GEN6_RP_DOWN_TIMEOUT - use 1s instead of 1.28s

Don't try to overclock, or program ring/IA frequency tables since we
don't quite have sufficient docs yet.

NOTE: These values do not reflect the changes made recently by Chris.
Since we have no evidence yet what the proper way to tweak for this
platform is, I think it is good to go, and can be optimized by Chris, or
whomever, later.

Ben Widawsky 46c764d41f drm/i915/bdw: Use HSW formula for ring freq scaling
The current formula we use for HSW is not what is in current docs.
However, changing to the HSW formula on my HSW does not improve power
usage, and decreases performance by about 5% in limited xonotic testing.

For gen8, until we know otherwise, or run experiments, let's use
the HSW formula - which should be the same used in the Windows driver
(and thus help make an apples-applies comparison) on gen8.

v2: Use >= 8 instead of > 7 to be consistent with all other gen
checks.

Ben Widawsky ed8546ac1f drm/i915/bdw: Support eDP PSR
Broadwell PSR support is a superset of Haswell. With this simple
register base calculation, everything that worked on HSW for eDP PSR
should work on BDW.

Note that Broadwell provides additional PSR support. This is not
addressed at this time.

v2: Make the HAS_PSR include BDW

v3: Use the correct offset (I had incorrectly used one from my faulty
brain) (Art!)

v4: It helps if you git add

v5: Be explicit about not setting min link entry time for BDW. This
should be no functional change over v4 (Jani)

now also build up PIPECONF completely ourselves - keeping around
random stuff set by the BIOS just isn't a good idea. I've checked BDW
BSpec and we already set all relevant bits.
