1libdrm - userspace library for drm
2
3This  is libdrm,  a userspace  library for  accessing the  DRM, direct
4rendering  manager, on  Linux,  BSD and  other  operating systes  that
5support the  ioctl interface.  The library  provides wrapper functions
6for the  ioctls to avoid  exposing the kernel interface  directly, and
7for chipsets with drm memory manager, support for tracking relocations
8and  buffers.   libdrm  is  a  low-level library,  typically  used  by
9graphics drivers  such as the Mesa  DRI drivers, the  X drivers, libva
10and  similar projects.  New  functionality in  the kernel  DRM drivers
11typically requires  a new  libdrm, but a  new libdrm will  always work
12with an older kernel.

15Compiling
16---------
17
18libdrm  is  a  standard  autotools  packages and  follows  the  normal
19configure, build  and install steps.   The first step is  to configure
20the package, which is done by running the configure shell script:
21
22	./configure
23
24By default, libdrm  will install into the /usr/local/  prefix.  If you
25want  to  install   this  DRM  to  replace  your   system  copy,  pass
26--prefix=/usr and  --exec-prefix=/ to configure.  If  you are building
27libdrm  from a  git checkout,  you first  need to  run  the autogen.sh
28script.  You can  pass any options to autogen.sh  that you would other
29wise  pass to configure,  or you  can just  re-run configure  with the
30options you need once autogen.sh finishes.
31
32Next step is to build libdrm:
33
34	make
35
36and once make finishes successfully, install the package using
37
38	make install
39
40If you are install into a system location, you will need to be root to
41perform the install step.
