The libdrm_freedreno helper layer for use by xf86-video-freedreno,
fdre (freedreno r/e library and tests for driving gpu), and eventual
gallium driver for the Adreno GPU. This uses the msm gpu driver
from QCOM's android kernel tree.
Note that current msm kernel driver is a bit strange. It provides a
DRM interface for GEM, which is basically sufficient to have DRI2
working. But it does not provide KMS. And interface to 2d and 3d
cores is via different other devices (/dev/kgsl-*). This is not
quite how I'd write a DRM driver, but at this stage it is useful for
xf86-video-freedreno and fdre (and eventual gallium driver) to be
able to work on existing kernel driver from QCOM, to allow to
capture cmdstream dumps from the binary blob drivers without having
to reboot. So libdrm_freedreno attempts to hide most of the crazy.
The intention is that when there is a proper kernel driver, it will
be mostly just changes in libdrm_freedreno to adapt the gallium
driver and xf86-video-freedreno (ignoring the fbdev->KMS changes).
So don't look at freedreno as an example of how to write a libdrm
module or a DRM driver.. it is just an attempt to paper over a non-
standard kernel driver architecture.
v1: original
v2: hold ref's to pending bo's (because qcom's kernel driver doesn't),
various bug fixes, add ringbuffer markers so we can emit IB's to
portion of ringbuffer (so that gallium driver can use a single
ringbuffer for both tile cmds and draw cmds.

Intel GPU Tools is newer and arguably better. This change doesn't
completely merge the files because it's a bit simpler if we move the
I9XX macro over to Intel GPU Tools, and don't move over a few macros
from IGT that libdrm doesn't care about.
It has been discussed, and would seem even easier if Intel GPU Tools
simply used the libdrm header files. Whether or not we move to that,
this should help that effort.

On Gen6, bit 15 is now `Depth Clear Value Valid`. This was being treated
as part of the length, and failing the rest of the batchbuffer decode.

We didn't set the ring flag for BLT batches, so they got run on the
render ring. Shenanigans ensued, especially when we sent commands that
were only valid on the BLT ring.

I'm fairly sure the extra flags it specifies no longer exist, so
there is no point in keeping it. It only adds a warning when
running make distcheck.

Due to the typo, none of the .xml files would end up in the release
tarball and cause make distcheck as well as builds from the tarball to
fail.
Using $() isn't strictly necessary but other variables and expressions
use that variant already so it makes the usage consistent.

Very similar to Evergreen, but slightly different rules for tile / slice
alignment. Fortunately, these map quite naturally onto the previous fixes for
linear aligned layout on SI.
2D tiling still needs more work here and possibly in the kernel.

This fixes all the out-of-tree build-failures with manpages and uses a
.man_fixup file to avoid overriding man-pages on every build.
Manpages are only built if xsltproc is found and the stylesheets are
available locally. You can disable building manpages with
--disable-manpages so the quite expensive xsltproc procedure can be
skipped.

As we clear the relocs from the bo, we also need to clear the
contribution of the reloc_target_bo from the fence count. Otherwise they
are leaked and prevent any further relocations being added to the bo.

I must have botched something in the push of the xml switchover, since I

This adds an overview page that describes Dumb-Buffers, TTM and GEM. It

If we want to use the manpages in external documentation other than normal
manpages, we should rather use XML. Furthermore, almost no-one knows troff
today, anyway, and XML allows others to easily add more pages without
having to learn troff.

Under certain circumstances it's possible for libdrm to decide to move
a GART|VRAM pushbuf to be VRAM-only. This causes the kernel to reject
the command submission on GF8 and up, due to a stricter policy where
buffers are only allowed to move to memory types that were specified
at creation time.
The simplest fix for this is to force the creation-time memory type for
the lifetime of the push buffer.

To avoid kernel rejecting cs if we return different global name
for same bo keep track of global name and always return the same.
Seems to fix issue with suspend/resume failing and repeatly printing
following message :
[drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -35!
There might still be way for a rogue program to trigger this issue.

If we have valid timings, we can at least set width/height to
*something*, which is I think at least less confusing than always
seeing width/height of zero. At least modeprint and modetest
seem to expect width/height to mean something.

We don't want to build libdrm tests with Cairo support under Poky, since
they're never used and also cause a build loop from libdrm -> cairo ->
mesa-dri -> libdrm.
To avoid variance in build results, introduce a --disable-cairo-tests
switch.

This allows texturing with depth-stencil buffers directly without the copy
to CB. The separate miptree description for stencil is added, because
the stencil mipmap offsets are not really depth offsets/4 (at least
