The only answer would be: read the kernel source. Here are the docs that are available: http://www.x.org/docs/AMD/ http://developer.amd.com/documentation/guides/Pages/default.aspx#open_gpu Afaict, there is no register documentation being made available by ATI anymore. All you get is the shader instruction sets from AMDs GPGPU people. The deal with AMD at the time was that all basic hw and display information would be made public (these days, our proposal can be read at http://www.phoronix.com/scan.php?page=article&item=amd_radeonhd_four&num=1), and that we at SuSE would not get any documentation that was not meant to be made public, but that we would get it already while it was in the process of being cleared legally. While the documents that we did get initially (soon 5 years ago) were cleared during the time the SuSE/AMD contract was in place, are made public today, the documents that we got later on, like some ATI R7xx registers docs and R7xx AtomBIOS documentation (we never saw AtomBIOS documentation for R5xx or any R6xx type chip), were not cleared in that timeframe and were subsequently not released, despite Mr Bridgmans initial assurance that these docs would go out. So all you have is the kernel source and Matthias Hopfs excellent AtomBIOS disassembler (in as far as the latter is still useful on recent AtomBIOSes). The disassembler is a real life saver when trying to figure out how the AtomBIOS interface changes, or with spotting bugs in the BIOS, but i have no idea how useful that becomes without any register information.
