    Phoronix: AMD Releases Microcode For All GPUs

    In the next step towards open-source 3D support for the R500 and R600 GPUs (Radeon X1000 and Radeon HD 2000/3000), AMD has just pushed its production microcode into the Mesa/DRM git tree. This is the microcode found in the fglrx driver and it covers the Radeon R100 to R600 product families.

    I think these efforts are certainly appreciated by the community.

          Is there still some work/activity based upon the new docs in Mesa repository?

            Really insane how fast the new releases are getting out for the developers... this is one of a few reasons why I only buy AMD/ATI products, they deserve every kind of support.

              Yes, but so far the work is happening in private branches -- the 3D work is still at the early stages so don't think anything has been pushed to master yet. If you monitor #radeon and watch for discussions between simpsonc, airlied, agd5f, glisse and others you'll have the very latest news

                My next Notebook will be one based on Puma plattform! I hope the manufactors will build some qualtity notebooks with this.

                  AMD with their open-source philanthropy
                  not a good use of the word 'philanthropy'. I know you mean 'generosity', but philanthropy is more towards humans (help those in need). Unless of course if you mean that the open-source developers are 'dying' to get this information and thus AMD, with their actions, save their lives :-P

                    This is very good, but I never hear specifically stated for the higher parts - like what about the RV670 (3870)?

                    TBF I have not scoured through the releases, but a person only looking at the newsies on websites would get the impression of only the lowend parts being "opened up".

                    Would someone please clarify?

                      Afaik the R600 3D documentation in one of the next candidates. Please confirm!

                      I have a Radeon X700 (r410) in my Notebook and i am very happy that the "low end" documentation is released.

                        RV670 microcode was included in today's release, along with RV620 and RV635. For the register specs, tried to pick one chip which was representative of the entire family, since the registers are pretty much the same across all the variants. We went with the docs for mobile parts (mobile uses more features of the chip). Going with a mobile part means choosing a low end or midrange GPU, but it doesn't matter since the registers are the same anyways.

                        There are a couple of exceptions, like the RV515 memory controller registers having a different offset than the rest of the R5xx family. The latest parts (rv620/635) are also significantly different so we have one of those docs in the queue for cleanup and public release (the radeonhd devs have the info under NDA already).

                          frago, R600 3D is next on the list but there is still a fair amount of work to be done on the document.

                            Thank You!

                            I really appreciate AMD's support of open source drivers, and will recommend AMD graphics cards and processors whenever I have the opportunity!
