Hey all,
So in mesa for swtcl cases we emit vertices to DMA, and set a driver
internal dma.flush hook, we also set
ctx->Driver.NeedFlush |= FLUSH_STORED_VERTICES;
The driver has its FlushVertices pointed at the vbo_exec_FlushVertices
call.
I'm not sure when this ever worked but I assume it did at one stage in
r100 driver since I haven't really changed this code flow, I'm
contemplating doing something like the below but maybe someone can
say when this all got broken.
Dave.
