without really digging into what was going on.
Also, as mentioned in the related bug [1], having the quirk regressed
some of the machines it was supposed to fix to begin with, and there
were patches posted to disable the quirk on such machines [2]!
The fact is, we do need the BLM_PCH_PWM_ENABLE bit set to have
backlight. With the quirk, we've relied on BIOS to have set it, and our
save/restore code to retain it. With the full backlight setup at enable,
we have no place for things that rely on previous state.
With the per platform hooks, we've also made a change in the PCH
platform enable order: setting the backlight duty cycle between CPU and
PCH PWM enable. Some experimenting and
indicate that we can't set the backlight before enabling CPU PWM; the
value just won't stick. But AFAICT we should do it before enabling the
PCH PWM.
Finally, any fallout we should fix properly, preferrably without quirks,
and absolutely without quirks that rely on existing state. With the per
platform hooks have much more flexibility to adjust the sequence as
required by platforms.

drm/i915/bdw: GEN8 backlight support
Prior to Haswell the CPU control register for backlight
(BLC_PWM_CPU_CTL) toggled the PCH baclight pin for us. This made some
sense as there was no pin on the CPU. With Haswell came the introduction
of a CPU backlight pin, but the interface was still controlled by
software with the same mechnism. Behind the scenes, hardware did all the
dirty work for us.
Broadwell no longer provides this for free. If we want to use the PCH
backlight pin [1] then we have to set the override bit BLC_PWM_PCH_CTL1
and program BLC_PWM_PCH_CTL2 for the PWM values.
This patch implements that. This patch is compile tested only, and given
that I rarely if ever touch this code, careful review is welcome.
[1] According to Art, we know of no devices that exist which use the CPU
pin (and remember it has existed already on HSW). If such a device does
exist, we'll have to handle it properly - this is left as TODO until
then.

drm/i915: Deprecated UMS support
It's been 5 years since kms support was merged and roughly 4 years
since UMS support was ripped out from userspace drivers.
Thus far it's not been a big burden to keep the ums paths alive, and
we've made some good progress in better separating it from the kms
code by sprinkling DRIVER_MODESET checks all over the place.
But now that the drm demidlayering is within reach this changes. I
want to make the driver loading code more robust using devres.c and
other cool tricks. But that doesn't work with ums due to the
shadow-attach trick. Which means we either
a) need to split out a complete ums codebase like radeon has
b) kill it for good.
The 2nd option is obviously much less work than the first, so I think
it's time to test the waters and see how many people out there still
use ums.
I've decided that silently failing to initialize the driver (and not
e.g. failing to load the module) is the right thing. That way we
should only get reports from users that actually care about some ums
features (like accelerated gl or support for secondary outputs).
Everyone else will just fall back to the vesa X driver.
For developers there's a small info level dmesg output.
The plan is to drop this Kconfig option after 3.16 (so gives us 2 full
releases) and then start killing code for real 2-3 releases
afterwards. That should be more than enough time for users to pipe up.
Of course if anyone does we need to revisit this plan and maybe go
with option a) above.
Also enable the KMS support by default in Kconfig and polish the help
texts a bit.

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.

Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of

tolerate overly large values of N.

drm/radeon/audio: fix missing multichannel PCM SAD in some cases
The current code writing SADs to the audio registers seems to assume
that there is at most a single SAD per audio format.
However, that is not the case. Especially for PCM it is somewhat common
for sinks to have two SADs, one for 8-channel and one for 2-channel
audio, which may have different supported sample rates (i.e. the sink
supports stereo audio at higher sample rates than multichannel audio).
Because of this, only the 2-channel SAD may be used if it appears before
the 8-channel SAD. Unless other SADs require otherwise, this may cause
the ALSA HDA driver to allow stereo playback only.
Fix the code to pick the PCM SAD with the highest number of channels,
while merging the rate masks of PCM SADs with lower amount of channels
into the additional stereo rate mask byte.
Technically there are even more cases to handle (multiple non-PCM SADs
of the same type, more than two PCM SADs with varying channel counts,
etc), but those have not actually been encountered in the field and
handling them would be non-trivial.
