The main reason I was considering trying to work on UMS was the length of time it is taking me to get anywhere with porting the radeon KMS code and the feeling that even when I do get it all to compile I won't be able to debug it. I think the best plan for me is to get an older R600 card off eBay. Robert Swindells ___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati

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.

There hasn't been anything new in UMS world really in 2-3 years, I'd rather split it off and let those who care about it deal with it, a lot of changes have broken UMS recently. So far its also 61k loc less to worry about, along with reducing the complexity of the macros and spaghetti useEXA, XAA code.

Aren't there still some OS using this driver but not supporting kms? Though I guess it doesn't actually matter for them if they need to use the ums branch instead... Otherwise sounds good to me.

Not that anything newer than about R700 is even very useful without TTM for me. > we'd fork the current master into a UMS branch and move on. Well, that's better than nothing, at least assuming Someone maintains it.
