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 has two build systems, a legacy autotools build system, and a newer
-meson build system. The meson build system is much faster, and offers a
-slightly different interface, but otherwise provides an equivalent feature set.
-
-To use it:
+To set up meson:
meson builddir/
If you are installing into a system location you will need to run install
separately, and as root.
-
-
-Alternatively you can invoke autotools configure:
-
- ./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.
