[PATCH] nv50/gallium: submit user vbufs through the fifo
...upload data doesn't invalidate caches on the GPU side or doesn't make it wait for the data - uploading stuff with SIFC instead of memcpy helps there, but it's still a lot slower than using VERTEX_DATA since we'd upload everything. The blob does it the same way for drawing with glVertex/Color/AttribArray(user space pointer) (except it converts everything to float). Maybe someone wants to comment on the implementation here, though. -------------- next part --------------
