Re: [Mesa3d-dev] radeon r200 TCL in xorg-video-ati 6.10

Thank you, Roland, that explains it all. When i said the code was
running that much faster on almost the same configuration - that other
config is AGPx4, with a native OSX driver edge for the rv280 (it's a
mac). And yes, the vertex arrays are large. So in one case we have
larger vertex arrays perpetually traversing a (66MHz) PCI bus, in the
other - proper VBOs over an AGPx4 bus - that could easilly account for
an order of magnitude, and then some, for this task. And this given
that fillrate alone is better on the PCI ATI (later model, faster
clocks, wider memory bus, etc).

let's say i decided to hack a rudimentarty allocate-only/no-deallocate
memory manager for STATIC_DRAW VBOs into the edge, not for
upstreaming, just for my purposes here, where would you advise me to
start looking at? Also, should i be able to do with just the present
sources, no futher NDA'd specs required?

Thank you again,
martin
