update checks it.
Upstream fixed this differently, but that fix doesn't work for us as our
ioctl(2) subsystem works differently from Linux.

restore something properly after resume which makes the render ring get stuck.
By defaulting to the "blt" acceleration method we avoid the use of this ring
and the machine remains usable after resume.
People who really want full 2D acceleration can still override the acceleration
method in their xorg.conf.

newer X.Org (2.99.917 or master) version cause corruption on older
machines (X40, i965), probably caused by a bug in our kernel,

major releases ago. Furthermore it requires the userland AGP interface
that was removed from the kernel with 5.6. These devices should work
fine with the vesa driver.

on ivy bridge, mostly based on upstream drm code:
- remove a workaround which was in itself causing issues
- switch the order of disabling fdi rx & tx
- disable DPLL_SEL when disabling the crtc
- add a few extra delays
Most of this concerns the gen5+ crtc disable function, and thanks
to a bunch of testers this is known to still work fine on gen 5/6/7.

Apparently previous version was generated with some of my local changes
to use /usr/bin/libtool. This is causiing problems with the XvMC libs
shared libraries versions.

- remove one of the output probe method in i830PreInit(). This method is
calling functions that are normally forbidden in PreInit(). With
xserver 1.13 this causes a fatal error at run time.

Backlight control via the brightness buttons won't yet work as
that likely requires opregion/acpi bits.

multiple display pipes from working. The third pipe on ivy bridge
remains disabled for now.

Since recent(ish) changes we can allocate roatated framebuffers with tiling.
This was not taken into account. Fix this for the most part:
1) i830_display_tiled needs to check tiling on rotated buffers too.
2) PipeSetBase needs to not only set offset to 0 for roated shadow buffers, it
also needs to 0 DSPTILEOFF x/y too.
There seems to be a remaining issue with damage or similar causing some latency
on rotated screens, I have not managed to find this yet.

though the cracks, hence late commit).

"normal" 2D stuff is pretty solid and it is really nice to be able to use
my laptop at the panel's native resolution and be able to suspend and resume
the machine.

Backporting keeping UMS changes by me, some bugfixes from kettenis@.
Has been in snapshots for a while, committed on request so we can be
sure what people are running. This is a prerequesite for sandybridge
support but has those chipsets disabled for now until the correct code
has been added.
