I'd like some input on the VBO stuff in r300. In r300_context.h we have the
following.
/* KW: Disable this code. Driver should hook into vbo module
* directly, see i965 driver for example.
*/
/* #define RADEON_VTXFMT_A */
#ifdef RADEON_VTXFMT_A
#define HW_VBOS
#endif
So the VTXFMT (radeon_vtxfmt_a.c) code is disabled anyway. This also disables
hardware VBOs. I guess this has been done since the new VBO branch was merged.
So, the question is, should this "dead" code be removed? I think all drivers are
(or should be) moving to the new VBO code anyway.
I've already made a patch for this, but I'm not committing until I get the okay
from a few people.
Thanks.
