    Phoronix: This Is What Started AMD's Open-Source Strategy

    While AMD's open-source strategy was announced on Phoronix on 7 September 2007, it was on 17 September of the same year that the Novell/SUSE developers did their first public release of their xf86-video-radeonhd driver. This was the X.Org driver created by the Novell Linux engineers in months prior for R500 and R600 GPUs. Here is some special reading -- a letter that was volleyed from Novell to AMD that kicked off this entire process -- to celebrate what would have been the fourth birthday of this open-source Linux driver.

      now make a good an fast drivers so i can play quake live on 4850 on open drivers... now it is 60 fps, but screen is choppy.

      i can use my computer as beta test machine

        All I would like is power management, especially for my E-350-based notebook...

          You're wrong.

          Yeah, but dynpm/low are too buggy to be default, so there's nothing we can do.

          That's what dynpm will do in the future (clock dependend on the workload). It's not really working yet. And low has problems even on the desktop.

          Power Management is hard to do but I agree its priority should be higher than it is right now.

          Not sure if serious...? Power management is important because of the power consumption. The fan in my subnotebook is quiet enough (totally different story with my desktop, powered by a 6870).

            The drivers default to "default" because that is the only thing that runs reliably on all systems so far.

              Lets say your claim is true.
              Then what decides the "default profile"?
              The BIOS that lacks it?
              Some non-existing user setting?
              Hardware defined?
              Basiacally what needs to be done is to:
              1. Set low or medium as default profile
              2. Fix dynpm!

                I'll take "blind" for $300, Alex.

                I read that thread a few more times but didn't see any indication of default not running on the user's system. It didn't reduce power, obviously, but it also didn't crash at boot which is the problem on some systems if the driver defaults to mid, low, dynpm or anything else. As long as the system boots up (which it does with "default") the user can adjust power levels; if the system crashes at boot that's a lot harder.

                The video BIOS contains a power settings table, with one or more entries. One of those entries is marked as "default". The VBIOS uses that entry when setting up the hardware, and IIRC "default" in the driver means "don't mess with whatever the VBIOS set".

                When you say "The BIOS that lacks it", what does "it" refer to ?

                  agd5f has mentioned it here a couple of times IIRC, also discussion on #radeon over the last couple of years
