    2 DRM README file
    3 
    4 
    5 There are two main parts to this package: the DRM client library/interface
    6 (libdrm.so) and kernel/hardware-specific device modules (such as radeon.ko).
    7 The kernel device modules are not shipped with libdrm releases and should only
    8 be built from the git tree by developers and bleeding-edge testers of
    9 non-Intel hardware.  The Intel kernel modules are developed in the Linux
   10 kernel tree.
   11 
   12 
   13 Compiling
   14 ---------
   15 
   16 By default, libdrm and the DRM header files will install into /usr/local/.
   17 If you want to install this DRM to replace your system copy, say:
   18 
   19         ./configure --prefix=/usr --exec-prefix=/
   20 
   21 Then,
   22         make install
   23 
   24 
   25 To build the device-specific kernel modules from the git tree:
   26 
   27         cd linux-core/
   28         make
   29         cp *.ko /lib/modules/VERSION/kernel/drivers/char/drm/
   30            (where VERSION is your kernel version: uname -f)
   31 
   32 Or,
   33         cd bsd-core/
   34         make
   35         copy the kernel modules to the appropriate place
   36 
   37

   39 Tips & Trouble-shooting
   40 -----------------------
   41 
   42 1. You'll need kernel sources.  If using Fedora Core 5, for example, you may
   43    need to install RPMs such as:
   44 
   45         kernel-smp-devel-2.6.15-1.2054_FC5.i686.rpm
   46         kernel-devel-2.6.15-1.2054_FC5.i686.rpm
   47         etc.
   48 
   49 
   50 2. You may need to make a symlink from /lib/modules/VERSION/build to your
   51    kernel sources in /usr/src/kernels/VERSION (where version is `uname -r`):
   52 
   53         cd /lib/modules/VERSION
   54         ln -s /usr/src/kernels/VERSION build
   55 
   56 
   57 3. If you've build the kernel modules but they won't load because of an
   58    error like this:
   59 
   60         $ /sbin/modprobe drm
   61         FATAL: Error inserting drm (/lib/modules/2.6.15-1.2054_FC5smp/kernel/drivers/char/drm/drm.ko): Invalid module format
   62 
   63    And 'dmesg|tail' says:
   64 
   65         drm: disagrees about version of symbol struct_module 
   66 
   67    Try recompiling your drm modules without the Module.symvers file.
   68    That is rm the /usr/src/kernels/2.6.15-1.2054_FC5-smp-i686/Module.symvers
   69    file (or rename it).  Then do a 'make clean' before rebuilding your drm
   70    modules.
