1 libdrm - userspace library for drm 2 3 This is libdrm, a userspace library for accessing the DRM, direct 4 rendering manager, on Linux, BSD and other operating systes that 5 support the ioctl interface. The library provides wrapper functions 6 for the ioctls to avoid exposing the kernel interface directly, and 7 for chipsets with drm memory manager, support for tracking relocations 8 and buffers. libdrm is a low-level library, typically used by 9 graphics drivers such as the Mesa DRI drivers, the X drivers, libva 10 and similar projects. New functionality in the kernel DRM drivers 11 typically requires a new libdrm, but a new libdrm will always work 12 with an older kernel. 13 14 15 Compiling 16 --------- 17 18 libdrm is a standard autotools packages and follows the normal 19 configure, build and install steps. The first step is to configure 20 the package, which is done by running the configure shell script: 21 22 ./configure 23 24 By default, libdrm will install into the /usr/local/ prefix. If you 25 want to install this DRM to replace your system copy, pass 26 --prefix=/usr and --exec-prefix=/ to configure. If you are building 27 libdrm from a git checkout, you first need to run the autogen.sh 28 script. You can pass any options to autogen.sh that you would other 29 wise pass to configure, or you can just re-run configure with the 30 options you need once autogen.sh finishes. 31 32 Next step is to build libdrm: 33 34 make 35 36 and once make finishes successfully, install the package using 37 38 make install 39 40 If you are install into a system location, you will need to be root to 41 perform the install step. 42
