Chris Wilson c4b00767a7 intel: Support passing of explicit fencing from execbuf
Allow the caller to pass in an fd to an array of fences to control
serialisation of the execbuf in the kernel and on the GPU, and in return
allow creation of a fence fd for signaling the completion (and flushing)
of the batch. When the returned fence is signaled, all writes to the
buffers inside the batch will be complete and coherent from the cpu, or
other consumers. The return fence is a sync_file object and can be
passed to other users (such as atomic modesetting, or other drivers).

libdrm - userspace library for drm

This  is libdrm,  a userspace  library for  accessing the  DRM, direct
rendering  manager, on  Linux,  BSD and  other  operating systems that
support the  ioctl interface.  The library  provides wrapper functions
for the  ioctls to avoid  exposing the kernel interface  directly, and
for chipsets with drm memory manager, support for tracking relocations
and  buffers.   libdrm  is  a  low-level library,  typically  used  by
graphics drivers  such as the Mesa  DRI drivers, the  X drivers, libva
and  similar projects.  New  functionality in  the kernel  DRM drivers
typically requires  a new  libdrm, but a  new libdrm will  always work
with an older kernel.


Compiling
---------

libdrm  is  a  standard  autotools  package and  follows  the  normal
configure, build  and install steps.   The first step is  to configure
the package, which is done by running the configure shell script:

	./configure

By default, libdrm  will install into the /usr/local/  prefix.  If you
want  to  install   this  DRM  to  replace  your   system  copy,  pass
--prefix=/usr and  --exec-prefix=/ to configure.  If  you are building
libdrm  from a  git checkout,  you first  need to  run  the autogen.sh
script.  You can  pass any options to autogen.sh  that you would other
wise  pass to configure,  or you  can just  re-run configure  with the
options you need once autogen.sh finishes.

Next step is to build libdrm:

	make

and once make finishes successfully, install the package using

	make install

If you are installing into a system location, you will need to be root
to perform the install step.
