1 1.1 mrg 2 1.1 mrg DRM README file 3 1.1 mrg 4 1.1 mrg 5 1.1 mrg There are two main parts to this package: the DRM client library/interface 6 1.1.1.2 mrg (libdrm.so) and kernel/hardware-specific device modules (such as radeon.ko). 7 1.1.1.2 mrg The kernel device modules are not shipped with libdrm releases and should only 8 1.1.1.2 mrg be built from the git tree by developers and bleeding-edge testers of 9 1.1.1.2 mrg non-Intel hardware. The Intel kernel modules are developed in the Linux 10 1.1.1.2 mrg kernel tree. 11 1.1 mrg 12 1.1 mrg 13 1.1 mrg Compiling 14 1.1 mrg --------- 15 1.1 mrg 16 1.1 mrg By default, libdrm and the DRM header files will install into /usr/local/. 17 1.1 mrg If you want to install this DRM to replace your system copy, say: 18 1.1 mrg 19 1.1 mrg ./configure --prefix=/usr --exec-prefix=/ 20 1.1 mrg 21 1.1 mrg Then, 22 1.1 mrg make install 23 1.1 mrg 24 1.1 mrg 25 1.1.1.2 mrg To build the device-specific kernel modules from the git tree: 26 1.1 mrg 27 1.1 mrg cd linux-core/ 28 1.1 mrg make 29 1.1 mrg cp *.ko /lib/modules/VERSION/kernel/drivers/char/drm/ 30 1.1 mrg (where VERSION is your kernel version: uname -f) 31 1.1 mrg 32 1.1 mrg Or, 33 1.1 mrg cd bsd-core/ 34 1.1 mrg make 35 1.1 mrg copy the kernel modules to the appropriate place 36 1.1 mrg 37 1.1 mrg 38 1.1 mrg 39 1.1 mrg Tips & Trouble-shooting 40 1.1 mrg ----------------------- 41 1.1 mrg 42 1.1 mrg 1. You'll need kernel sources. If using Fedora Core 5, for example, you may 43 1.1 mrg need to install RPMs such as: 44 1.1 mrg 45 1.1 mrg kernel-smp-devel-2.6.15-1.2054_FC5.i686.rpm 46 1.1 mrg kernel-devel-2.6.15-1.2054_FC5.i686.rpm 47 1.1 mrg etc. 48 1.1 mrg 49 1.1 mrg 50 1.1 mrg 2. You may need to make a symlink from /lib/modules/VERSION/build to your 51 1.1 mrg kernel sources in /usr/src/kernels/VERSION (where version is `uname -r`): 52 1.1 mrg 53 1.1 mrg cd /lib/modules/VERSION 54 1.1 mrg ln -s /usr/src/kernels/VERSION build 55 1.1 mrg 56 1.1 mrg 57 1.1 mrg 3. If you've build the kernel modules but they won't load because of an 58 1.1 mrg error like this: 59 1.1 mrg 60 1.1 mrg $ /sbin/modprobe drm 61 1.1 mrg FATAL: Error inserting drm (/lib/modules/2.6.15-1.2054_FC5smp/kernel/drivers/char/drm/drm.ko): Invalid module format 62 1.1 mrg 63 1.1 mrg And 'dmesg|tail' says: 64 1.1 mrg 65 1.1 mrg drm: disagrees about version of symbol struct_module 66 1.1 mrg 67 1.1 mrg Try recompiling your drm modules without the Module.symvers file. 68 1.1 mrg That is rm the /usr/src/kernels/2.6.15-1.2054_FC5-smp-i686/Module.symvers 69 1.1 mrg file (or rename it). Then do a 'make clean' before rebuilding your drm 70 1.1 mrg modules. 71 1.1 mrg 72 1.1 mrg 73
