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

[[!format txt """ git clone git://anongit.freedesktop.org/xcb/pthread-stubs cd pthread-stubs ./autogen.sh --prefix=/usr make install """]]

xorg macros

[[!format txt """ git clone git://anongit.freedesktop.org/xorg/util/macros cd macros ./autogen.sh --prefix=/usr make install """]]

DRM and libdrm

[[!format txt """ 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 """]]

Mesa

xproto and x11proto from upstream is needed: [[!format txt """ 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 """]]

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 [[!format txt """ ./autogen.sh --prefix=/usr --libdir=/usr/lib64 --with-dri-drivers=openchrome --disable-glut --disable-gallium """]] Link to latest upstream changes : http://cgit.freedesktop.org/mesa/mesa/log/?h=openchrome-branch

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: [[!format txt """ 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.
