TTM stack build howto

WARNING : This is not for public consumption yet, don't try this at home unless you understand what you are doing.

Caveats

  * Must run with DRM installed. 
  * XvMC not working yet. 

Pre-requisites

  * Linux kernel >= 2.6.27. 2.6.26 may work as well. 
  * Xserver >= 1.4. If you want to run the 3D driver, you'll need at least 1.5. 
  * pthread-stubs and xorg macros. 

Components in install order

(This was tested on a fully updated Fedora 10, Archlinux 2009.08 system, Gos 3.1 Gadgets, and Debian sid / unstable. All binary and devel packages used to compile the openchrome TTM stack can be taken from upstream (the original source) or using your distribution's package manager.)

pthread-stubs

git clone git://anongit.freedesktop.org/xcb/pthread-stubs
cd pthread-stubs
./autogen.sh --prefix=/usr
make install

xorg macros

git clone git://anongit.freedesktop.org/xorg/util/macros
cd macros
./autogen.sh --prefix=/usr
make install

DRM and libdrm

git clone git://anongit.freedesktop.org/mesa/drm
cd drm
git checkout --track -b modesetting-newttm origin/modesetting-newttm
./autogen.sh --prefix=/usr
make
make install

cd linux-core
make LINUXDIR=/lib/modules/`uname -r`/build DRM_MODULES="openchrome"
mkdir -p /lib/modules/`uname -r`/updates/kernel/drivers/char/drm
install -m 744 drm.ko /lib/modules/`uname -r`/updates/kernel/drivers/char/drm
install -m 744 openchrome/openchrome.ko /lib/modules/`uname -r`/updates/kernel/drivers/char/drm
depmod -ae

libwsbm

wget http://cgit.freedesktop.org/mesa/libwsbm/snapshot/libwsbm-375a9b16472031d603fd0d2f3cbea3e1ed9bc6c7.tar.gz
tar zxf libwsbm*.tar.gz
cd libwsbm*

OpenChrome

svn co http://svn.openchrome.org/svn/branches/ttm_branch
cd ttm_branch
./autogen.sh --prefix=/usr \
             --disable-static \
             --enable-debug \
             --enable-xv-debug
make
make install

Mesa

xproto and x11proto from upstream is needed:

git clone git://anongit.freedesktop.org/xorg/proto/xproto
git clone git://anongit.freedesktop.org/xorg/proto/x11proto
cd xproto
./autogen.sh --prefix=/usr
make install
cd ../x11proto
./autogen.sh --prefix=/usr
make install

git clone git://anongit.freedesktop.org/mesa/mesa
cd mesa
git checkout --track -b openchrome-branch origin/openchrome-branch
./autogen.sh --prefix=/usr --with-dri-drivers=openchrome --disable-glut --disable-gallium
make
make install

For 64 bit users

When compiling mesa on a 64-bit machine with a 64-bit operating system, you must use the following ./autogen.sh line

./autogen.sh --prefix=/usr --libdir=/usr/lib64 --with-dri-drivers=openchrome --disable-glut --disable-gallium

Please note

When compiling mesa, the version string may not change in glxinfo. That is because mesa was installed to /usr/lib/dri rather than /usr/lib/xorg/modules/dri. To fix this if it does not work:

cd mesa
./autogen.sh --prefix=/usr --with-dri-driverdir=/usr/lib/xorg/modules/dri --with-dri-drivers=openchrome --disable-glut
make
make install

Todo list

1. Fix EXA problems
2. Get XvMC working again.
3. Merge with trunk to get the latest modesetting / cursor bits.
4. Fix the 2D driver so it will run without DRM
5. Start merging in VIAs Chrome 9 bits into the new DRM.
