Otherwise the newshiny irq-driven gmbus and dp aux code won't work that

v2: Simple move drm_irq_install before intel_modeset_gem_init, as
suggested by Ben Widawsky.
The gmbus interrupt generation is rather fiddly: We can only ever
enable one interrupt source (but we always want to check for NAK
in addition to the real bit). And the bits in the gmbus status
register don't map at all to the bis in the irq register.
To prepare for this mess, start by extracting
Only enables the interrupt and puts a irq handler into place, doesn't
do anything yet.
Unfortunately there's no gmbus interrupt support for gen2/3 (safe for
pnv, but there the irq is marked as Test mode).

We need two special things to properly wire this up:
- Add another argument to gmbus_wait_hw_status to pass in the
correct interrupt bit in gmbus4.
- Since we can only get an irq for one of the two events we want,
hand-roll the wait_event_timeout code so that we wake up every
jiffie and can
The same optimization has already been applied to the ivb irq handler in

At least on the platforms that have a dp aux irq and also have it
enabled - vlv/hsw should have one, too. But I don't have a machine to
test this on, and the current code doesn't support dp yet anyway on
those platforms. Judging from docs there's no dp aux interrupt for gm45.
Also, I only have an
Hi All,
New -testing cycle. Highlights from this -next:
- New modeset code framework.
- Tiny fix in the fb helper to go through the official dpms interface
instead of calling the crtc helper code.
- forcewake code frobbery from Ben, code should be more in-line with what
Windows does now.

Currently we've only frobbed this bit at irq_init time, but did
not restore it at resume time. Move it to the gen3 clock gating
function to fix this.
Notice while reading through code.

Less clutter in the traces. And in both cases we yell rather loud
into the logs if we time out. Patch suggested by Chris Wilson.

going into powersave mode.
