Pinging this bug again, new progress:
- with the X server provided with Xubuntu 8.04, a recent drm.ko compiled from
a fresh git extract, the distro-provided 6.8.0 mach64 driver, and 16-bit color
depth, there is much less crashes - instead, we have occasional screen
corruption and z troubles:
- Google Earth works most of the time (froze machine once), but windows
appearing over the 3D display port disappear in a blink => context priority
issue?
- glxgears performance reached 300 fps (indirect; 110 fps) => not a bug, it's
cool :)
- Xfce's compositing works; however, when a menu is set to appear, the
rectangle it will fill contains garbled content (snow, or graphical elements
leftover from previously displayed element) => memory addressing troubles?
- Earth3D didn't display textures; however, that could have been a network
error
- Stellarium worked
- EXA is generally faster than XAA, except when displaying Flash videos in
Firefox (2 or 3): as far as I know, Flash uses blits - well, EXA blits are
slow...
In short: I'd say this specific bug may be mostly resolved closed with an X
server upgrade, but there still are problems in the mach64 drm module:
- context priority needs work
- memory addressing is unsafe (corruption, still occasional system freezes)
- 32-bit performance, well, sucks... but that may be a hardware limitation.
- EXA needs some love
