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.

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.

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.

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.

It warns about totally sensible things done in intel_decode.c. I've

There can be scenarios, especially when re-importing an existing buffer,
where you end up with multiple 'struct omap_bo's wrapping a single GEM
object handle. Which causes badness when the first of the evil-clones
is omap_bo_del()'d.
To do this, introduce reference counting and a hashtable to track the
handles per fd.
First, to avoid bo's slipping through the crack if multiple 'struct
omap_device's are created for one drm fd, a hashtable mapping drm
fd to omap_device, and the omap_device itself is reference counted.
Per omap_device, we keep a handle_table mapping GEM handle to omap_bo.
When buffers are imported from flink name or dmabuf fd, the handle
table is consulted, and if an omap_bo already exists, it's refcnt is
incremented and it is returned. For good measure, to avoid the
handle_table being deleted before the omap_bo is freed, the omap_bo
holds a reference to the omap_device.
TODO: check the overhead of the hashtable. If too much we could maybe
get away with only tracking exported and imported bo's in the table.
TODO: all the import/export flink/dmabuf operations are generic DRM
ioctls. Really all this functionality could be handled by a generic
drm_bo and drm_device "base class" that could be extended by omap,
exynos, etc. That would also allow more common userspace code by
avoiding artificial libdrm_omap dependencies.

this patch adds libdrm_exynos helper layer that inclues some intefaces
for exynos specific gem and virtual display driver and also adds exynos
module name to modtest and vbltest.
Changelog v2:
- fixed exynos broken ioctl.
the pointer of uint64_t *edid should be removed.
- removed unnecessary definitions.
- added drm prime interfaces.
this feature is used to share a buffer between drivers or memory managers

The empty string used for the not case is replaced by the default
if-else clause and so causes the configure to fail in the absence of
valgrind. Which is not quite what was intended.
Instead use the common idiom of setting a variable depending on whether
the true or false branch is taken and emit the conditional code as a
second step.

bo->referenced_in_cs is checked if bo is already in cs. Adding and removing
reference in bo is done with atomic operations to allow parallel access to a
bo from multiple contexts.
cs->id generation code quarentees there is not duplicated ids which limits
number of cs->ids to 32. If there is more cs objects rest will get id 0.
V2:
- Fix configure to check for atomics operations if libdrm_radeon is only selected.
- Make atomic operations private to libdrm.
This optimization decreases cs_write_reloc share of torcs profiling from 4.3%
to 2.6%.
