Just before making the 2.12.902 (2.13-rc2) snapshot.

Summarizing the 5 recent changes to the driver.

With libdrm < 2.4.22, the compilation of xf86-video-intel would fail
due to an undefined DRM_MODE_CONNECTOR_eDP. We now ensure that a
sufficiently new libdrm is available before compiling.

If we are tiled, we may fail the allocation due to an EIO and so not
being able to set tiling. Try again with an untiled request in this
case.

If we force fallbacks, then we will only create pixmaps in system
memory, preventing DRI2 from passing valid bo names to the clients. In
this case, they will just fallback to swrast. If we disable DRI2 after
forcing fallbacks (e.g. regenerating after a GPU hang or explicitly
disabled with the shadow buffer) then it is simpler just to disable the
extension and allow mesa to use pure swrast.

to that. No, it is not ready, hence add the sanity check to the

This is a slightly less risky strategy than having to remember to update

An attempt to workaround the incoherency in gen2 chipsets, we avoid
using dynamic reallocation as much as possible.

The first step is to disable allocation of pixmaps using GEM and simply
create them in system memory without a backing buffer object. This
forces all rendering to use S/W fallbacks.

The second step is to allocate a shadow front buffer and assign that to
the Screen pixmap. This ensure that the front buffer remains in the GTT
and pinned for scanout. The shadow buffer will be rendered to in the
normal fashion via the Screen pixmap, and be marked dirty. In the block
handler, the dirty shadow buffer is then blitted (using the GPU) over
the front buffer. This should completely avoid having to move pages
around in the GTT and avoid incurring the wrath of those early chipsets.
Secondly, performance should be reasonable as we avoid the ping-pong
caused by the small aperture and weak GPU forcing software fallbacks.

The current backlight value is clamped to the valid range [0, max] and
so as we queried the value before setting the max, we forced the current
backlight to 0 and so set it to be zero on initialising the display.

New ids for GT2 and GT2+ on desktop and mobile sandybridge, and
server sandybridge device ids.

Quoting Adam Jackson:

"But the X driver looks like
it never sets MONITOR_EDID_COMPLETE_RAWDATA, which means the X core
doesn't know that any sections beyond the first are present, so it won't
ever hand back more than 128 bytes to clients.  Boo."

This patch is based on his.

If the buffer object is tiled, we need to use the fence registers to
perform the appropriate untiling for CPU access. Ensure that we always
take this path for tiled objects, regardless of their size.

This reverts commit 9c3e3470.

This commit is not ready, as first the driver needs to handle all
controllers, especially those that ignore the BLC and require their own
interface.  Fortunately, by moving that discovery into the kernel - where
it just means finding which ACPI device is attached to the video and has a
backlight interface - the userspace code should become much more sane,
and work even with multi-gpu, multi-lid systems.

But that is for tomorrow.

Rather than assert, we should fixup the use of large A1 glyphs. However,
the simplest approach is to simply fallback to s/w.

If the i915 driver exposes a native ACPI interface to modify the panel
backlight use it in preference to the generic interfaces. On multi-GPU
systems, the panel backlight is meant to be connected via the IGP and
this ensures that we always find the right interface.

During -configure we would attempt to query the availablility of KMS
before the DRI module was loaded, thus we were unable to create a valid
