When selecting the native mode for a display we weren't taking into account
whether or not it was actually supported on that particular output.
This patch modifies our native mode selection to run all modes through
mode_valid() first.

It was once assumed that all G8x had dual-link TMDS everywhere, this isn't
actually the case - especially considering passive DP->DVI converters and
some HDMI connectors only support single-link.

We totally fail at detecting un-POSTed chipsets prior to G80. This commit
changes the pre-G80 POST detection to read the programmed horizontal total
from CRTC 0, and assume the card isn't POSTed if it's 0.
NVIDIA use some other heuristics more similar to what we do on G80, but I
wasted quite a long time trying to figure out the exact specifics of what
they do so we can try this for a bit instead.

Pineview with DDR3 memory has different latencies to enable CxSR.

We can, by virtue of a vblank interrupt firing in the middle of setting
up the unpin work (i.e. after we set the unpin_work field and before we
write to the ringbuffer) enter intel_finish_page_flip() prior to
receiving the pending flip notification. Therefore we can expect to hit
intel_finish_page_flip() under normal circumstances without a pending flip
and even without installing the pending_flip_obj. This is exacerbated by
aperture thrashing whilst binding the framebuffer

This doesn't change the clock limits (minimums), i.e. it won't make it
output 720x576 PAL nor 720x480 NTSC, but it will work with modes like
1080i etc. (including GLX and textured Xvideo, not sure about the
overlay).
Tested on i915 + analog VGA, it would be worth checking if newer chips
(and which ones) still support interlaced mode.

The BSD (bit stream decoder) ring is used for accessing the BSD engine
which decodes video bitstream for H.264 and VC1 on G45+. It is

The active list and request list move into the ringbuffer structure,
so each can track its active objects in the order they are in that

caused data to end up in the render cache. Objects gain a pointer to
the ring they are active on (if any).

- I915_GEM_GPU_DOMAINS moving to i915_drv.h to be used by both files.
- i915_gem_add_request had only half its implementation
copy-and-pasted out of the middle of it.
