    Best regards to Bridgman. And welcome to the new public face slash general punching bag

      Why you keep calling him the last name only. Why don't you call simply John. John B., etc. Is too confusing?
      I think Johnny here has really nice name.

        I haven't forgotten and am in the process of transitioning responsibility for the XvBA SDK to one of the developers on my (Embedded Linux) team which will help to get it back on track.

          Good luck in your future endeavours John. Hopefully you'll stick around and keep enlightening us occasionally.

          Tim, welcome to the position and the forums. Hopefully you've got the patience to deal with some of the people we've got here

            Not blind, but a lot of the work was less visible than usual. There were three big contributors to that :

            1. Moving to a new shader architecture (GCN), new memory management (GPUVM) and new shader compiler (llvm) at the same time. This was kind-of necessary but it meant that we had far more work in process where you couldn't see an obvious benefit. Using llvm was partly to build a good foundation for an open source OpenCL stack, and partly to get a more capable shader compiler into the graphics stack.

            2. Doing speculative development on the two remaining weak spots of the current driver stack -- power management and accelerated video decode. Historically there was so much catch-up work to be done that we focused development efforts in areas where we were pretty sure we would be able to release the resulting code, so there was little risk of wasted effort and (relatively) short delays between writing code and having the results publicly visible.

            In these last two areas we knew that the review/revise/repeat process would be a lot longer, but we reached the point where it made sense to dive in anyways. We had to write/debug a lot of code just to get the process going, so there was a bunch of work done there which hasn't shown you any real benefit yet.

            3. Making a big push to have launch-time open source support. This is the ultimate "developers do a lot of work but you don't see anything" investment because you don't see the results until closer to hardware launch date, but it is an important step.

            It's probably fair to say that more work has been done in the last year than any previous year, but relatively less of it has been immediately visible.
            You guys originally promised open-source release schedule parity with Windows in time for 8000 series. Not happening anymore?

              I don't think they promised, I think they said "we should have" or "we hope to have".

                To be precise, this is the first new GPU generation where development work was able to start early enough to give us a good chance of having support ready in time for product launch. I think what we said was "we're planning for it" (aiming for it / expecting it / working towards it, whatever) and that hasn't changed.

                The obvious question is "why didn't you just start earlier before ?", and the answer is "because support for each new generation builds on support for the previous generation, so we need to finish initial support for the previous generation first".

                  Thank you John Bridgman for all your work, and your openness here!
                  Welcome to Tim and good luck on helping us all

                  (I actually registered an account here just to talk with John... I was just reading before...)

                    So maybe you can answer the million dollar question then... UVD open source driver... when?

                      After five years of the open-source AMD strategy, John Bridgman is no longer managing these efforts...

                      You had a tough, often times thankless job (at least on this side of the fence) but I appreciate your efforts to communicate and inform.
                      Best of luck with the new gig!
