libdrm-2.4.0, xorg-server-1.5.0, mesa-7.2, and xf86-video-intel-2.5.0 was released, but ttm still does not work, and gem is still not out yet, so this is what i did:
1. download http://cgit.freedesktop.org/mesa/drm/tree/libdrm/xf86mm.h, put it in /usr/local/include/xf86mm.h
2. run EXTRA_ECONF=--enable-ttm-api emerge mesa, press Ctrl-Z right when configure is done
3. add:
| Code: | | #include <xf86mm.h> |
to the beginning of these files:
/var/tmp/portage/media-libs/mesa-7.2/work/Mesa-7.2/src/mesa/drivers/dri/common/dri_util.h
/var/tmp/portage/media-libs/mesa-7.2/work/Mesa-7.2/src/mesa/drivers/dri/i915/intel_bufmgr_ttm.c
4. continue the build by running fg
5. restart x (if you are on it)
there you have it!
EDIT: changed media-libs/mesa to media-libs/mesa-7.2 (thanks to dmpogo)

on my machine the path seems to be
/var/tmp/portage/media-libs/mesa-7.2/work/Mesa-7.2/src/mesa/drivers/dri/common/dri_util.h
etc |

works fine ! glxgears went from that 50 to 280. Not spectacular, but improvement  |

Thanks for the guide!
I have a question, what kernel are you using?

| ok, I have ttm working, but the performance is only about 80% of that of the original version of mesa (200fps vs 150fps in glxgears.) It doesn't really matter as long as redirected opengl works, but the performance should be better, not worse. What gives? I have an Intel 865G. |

Hei playing with that I noticed that somehow driconf tells me
could not connect any configurable direct-rendering devices
while
Code:
$ xdriinfo
Screen 0: i965
$ xdriinfo options i965
Driver "i965" is not installed or does not support configuration
This is with GM965, xf86-video-intel-2.5.0, mesa-7.2 patched for ttm
glxinfo is normal, glxgears, as I said went up with ttm.
(I have not tried xdriinfo before ttm patch, but I bet it was the same) |

Actually, I found out that it is ttm patch that kills driconf. Without it driconf works just fine, allows to set VBLANK be set to off, and fps for glxgears go up to 550 range (from 200 with ttm patch in).
So no I'm not sure ttm patch gains anything. |
