This reverts commit 3f11bbec42.
For unknown reasons, enabling tiling for the glyph cache is causing
glyph corruption both across suspend and resume and VT switching, on a
wide range of chipsets (reports include both i8xx and gm45)
This strongly suggests that we are handling tiling, or updates to tiled
buffers, incorrectly across i915_gem_idle(). However, until we can find
the root cause, we want to fix this regression before the next stable
release, so simply revert this patch. :(
Fixes:
[Bug 25406] fonts garbled after resuming from suspend since 6729b508http://bugs.freedesktop.org/show_bug.cgi?id=25406

This is the beginning of the campaign to remove some of the absurd use of
Hungarian in the driver. Not that I don't like Hungarian, but I don't need
to know that pI830 is a pPointer.
At this point, the only remaining feature regressions should be the lack of
overlay support (about to land), and the need to update the XVMC code to work
in the presence of KMS.

Desktop and mobile version of new chipsets are added.
Also do memory config like Intel 4 series chipset.

This is the intel video driver patch for a new chip, which is G33-like
and has some clocking setting related register changes. This patch adds
the pci id and DPLx/FPx register changes.
The gtt tool should just work to me, as the chip hasn't any changes
against G33 on this side.

Set alignments, tile settings and flags correctly in the 2D driver to support
tiled rendering. UXA's create pixmap function currently assumes the worst
about the alignment constraints; that should probably be fixed. Some of the
1M alignment fixes could probably be done more cleanly as well.
libpciaccess (and the old X server PCI code as well) provides a function to
get the ROM contents. Code to use that was already present in the driver and
used if the INT10 function failed. Skip the INT10 and just use libpciaccess
as that eliminates several module loads and scary use of vm86.

As xvmc rendering result has already been in fb, we shouldn't
do extra copy on it. Although special care is required for i915
xvmc surface pitch alignment, which must be at least 1KB aligned.
So video display function should take it into acount instead of
always setting Y pitch to be double of U/V pitch.
libpciaccess has a new structure that holds the PCI identifier data; borrow
macros from the mga driver to work with either the old xf86-specific
structure or the new libpciaccess structure.
These chipsets require that the hardware status page be referenced by an offset
in the GTT rather than a physical memory address, so the X Server allocates it
rather than the DRM.
Because stolen memory happens to be a contiguous block of high system memory,
we can just read the GTT entries for it to get physical addresses for our
allocations there if needed. This reduces fragmentation of the aperture space,
and will often reclaim up to 7 MB of memory that had been left unused since the
simplified aperture manager was put in place, but without reintroducing the
complexities of the old aperture manager.
With the new mode setting code, rotation is handled outside of the driver,
so the old usage of the 'shadow' module is no longer needed. Code to
initialize the crtc structures has been moved out of the driver and into the
modes code.
