Register reference guide tips up
STICKING TO ITS promises to better support the open sauce community, AMD has started to publish specifications for some of its GPUs. First up - in-depth technical docs for RV630.
You can find the specs
here. The document is a thrilling 'register reference guide', which contains page upon page of fascinating detail, including the revelation that MOP, in 18:16 bits, relates to a DRAM command where parameter 0 results in a NOP.
Furthermore, MEM_STATUS_SEL, in 12 bits, enables 0=Vertical and 1=Horizontal. Sounds like us after a night out with the Mageek - horizontal and with a dubious memory status.
M56 also gets a register reference guide, and more documents are expected to be shared soon over
here. Grab the cocoa and a reading light, folks.
