Looks like your suspicions about the vertex buffer not being in system
memory were right. Even if I move every single calculation from
gen_block_verts into the vertex shader the cpu time spend in this
function doesn't goes below ~35%.
I also doesn't understand why it's only gen_block_verts and not
gen_macroblock_verts. Probably because most blocks are only intra
blocks, but we will see if this changes when I manage to implement
proper buffer usage modes into r600g.
