The doc is a bit misleading, but I think I got it. according to 6.5.2
{INPUT|OUTPUT|TEMP}_VTX_MEM_SIZE = 72 (for r300)
{INPUT|OUTPUT|TEMP}_VTX_MEM_SIZE = 128 (for r500)
In this case here 8 inputs => 72/8 => PVS_NUM_SLOTS = 9. qed :)
According to 6.4.2 MAX_CNTRLS is 6, but 6.5.2 says 5. fglrx usess 6, so it
looks like there's a typo in 6.5.2.
The docs (both r500v1.3 and r300) also say to set VF_MAX_VTF_NUM in VAP_CNTL to
12=0xc. But this value crashes my card. fglrx sets it to 0xb, without crash. So
for this value the doc is wrong.
I'll try an implementation.
