Summary: Cogs: GPU hang Product: Mesa Version: git Platform: Other URL: http://www.humblebundle.com/ OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: sa@whiz.se

The game Cogs (from the Humble Indie Bundle) is causing a GPU hang. Unless the process is killed quickly the reset functionality doesn't seem to work so a full reboot is necessary.
The hang only happens if shadows is turned on in the game options, which it is by default so the hang happens right after launching the game.
No difference between 7.11 and git master.
Something else seems to be wrong with the game as it's pegging the CPU at 100% and performance is just a few frames per second.

It does! Thank you :)
The game is still really slow, but I'll open another bug about that, possibly first see if it's only on r600g or something common to all Mesa/G3D drivers.

[PATCH] gallium: vertex buffer optimization
This experimental patch should help with performance in cogs, though it needs more work and testing. I'm not sure if it's the right way to implement such optimization at all.

It seems to work fine here. There's a night-and-day difference with and without this patch!

r300g support for previous patch (not tested)

I think it should be rewritten in more generic way, so that the specific drivers won't need to care about it. I'll look into it.
But if you want to test this in its current state, then you could try attached patch for r300g, it needs to be applied after the previous patch. I can't test without r300 hw though, so I'm not sure it'll work.

It works fine with my RV530 card.
