    It probably does send it back encrypted, but it may not be a strict requirement with the ms signed drivers nonsense.

      It wouldn't be the same driver anyway, since the DRM driver is fglrx. The question therefore, is HOW different is UVD from crystalhd? WHY can't AMD just do the same thing? Can crystalhd be enhanced to support UVD without too absurd of a rewrite?

        Just to be clear, I haven't said that we *can't* provide open source driver support for UVD, just that we hadn't looked at it yet (and didn't plan to until we got caught up with 2D/3D/Xv on all GPU families) and that you should *assume* there will not be open source support unless/until we say otherwise (ie don't buy the parts on the assumption that open source UVD support will appear).

          Right... and you're pretty close to caught up now, aren't you?

            Hey, how 'bout hiring me to do it....?
            I have 2 applicable degrees, some unrelated work experience, a real estate license, and I live 2 minutes from where you work...

              Yep, and we kicked off the investigation a couple of weeks ago.

                      Attempted Translation: Why be happy about this news? They will likely soon discover that they cannot open UVD due to copy-protection concerns and will then officially announce UVD support is never coming to the Free drivers.

                      I think.

                        Go back a few posts and read what I wrote about crystalhd. It may very well be the case that broadcom has already taken the risk for them.... or maybe even already jeopardized AMD DRM... or proven that its ok. In any case, they've blazed the trail, so it might not be all that hard now.

                            Where is the source available?

                            I've been hunting on AMD web site and the web but can't find the source.

                            Does anyone have a URL for this Ontario driver?

                            Thanks!

                              It's an open source driver, so you need to look in the upstream projects.

                              Kernel code is in the radeon-testing branch of airlied's drm tree : http://git.kernel.org/?p=linux/kerne...radeon-testing

                              Mesa and ddx code is in the respective freedesktop.org projects (mesa/mesa and xorg/driver/xf86-video-ati).

                              Do you actually have Ontario hardware ?

                                Thanks for the information.

                                Of course I don't have Ontario hardware - I just wanted to look at the code.
