i965g driver fails to create pipe_screen and falls back to software rendering. It tries to create it with radeon chip id instead of intel chip id. 'startx' outputs the following errors:

i965_drm_winsys_screen_create
brw_screen_create: unknown pci id 0x68e0, cannot create screen
dri_init_screen_helper: failed to create pipe_screen


Intel graphic controller is on cpu, core i5-460M arrandale, PCI:0:2:0, 0x0046.
radeon graphic controller is Mobility Radeon HD 5000 Series, PCI:1:0:0, 0x68e0.
Mesa and DRI drivers were built from git bd5b7a6f7113da38a2c1f07a4a71e9993666a567 (master from today).

AFAIK the i965 gallium driver is completly unsupported.

> AFAIK the i965 gallium driver is completly unsupported.

That's right.

I'm not sure if we should make this more explicit or simply disable/remove the driver. The latest person to do a i965g specific change was Dave Airlie on Jan.

Comment 3 Tobias Jakobi 2011-05-16 08:40:34 UTC

I would vote at least for a big warning when enabling i965g in configure.

Removing the complete driver probably isn't a good idea. IIRC the i915 gallium driver was also unmaintained a long time and now someone (I think it was Daniel Vetter) is doing a lot of work on that one. Maybe something like that will happen for i965g too.
