    Phoronix: GLAMOR 0.5 To Advance 2D Over OpenGL

    With the Radeon driver now supporting GLAMOR acceleration -- it works for all hardware, but for Radeon HD 7000 series and newer its the only way of 2D HW acceleration -- this 2D-over-OpenGL architecture became more interesting...

          May i ask where in the stack 2d graphics are still needed???

          Don't all the 2d graphics libraries have backends for OpenGL or OpenVG which already has a G3D state tracker??

            If glamor doesn't plan to work on wayland it's a dead story within at most 5 years, since X will be dead on Linux by then just like X is dead on the Mac (not really dead, a long deprecated and unwelcome compatibility).

              Mesa has a sw limit of 8k on textures? Why?

              I recall there's already hw out that does 16k.

                this is a rather unique situation!

                Intel payed devs develop glamour, but don't use it
                amd payed devs actually use it!

                Those 2 (amd and intel) are rivals right?
                It's nice to see.

                  I tested glamor with my hd4550 and the systray icon of pidgin was always blank :-(

                    Glamor on a Radeon HD 4850 felt rather slow compared to EXA acceleration.
                    Also, it does not support Zaphod mode yet.

                      Glamor w/ radeon works fine here, but performance is much worse than EXA, and there are various artefacts. I remain unimpressed, and I am pretty sure it will stay that way.

                        That would be close to a disaster for users of Radeon HD 7000+ chipsets.

                          entropy, there's nothing in the hardware that ties it to Glamour, so at worst it would be a "temporary inconvenience" not a "disaster"...

                            Sorry, for getting infected by the tabloid speech.

                            What's the plan for 2d on SI+ then?
                            I thought it should be just Glamor (apart from ShadowFB).

                            Not sure how much the 2d performance depends on the compositor.
                            I don't use one of those eye-candy 3d compositors and scrolling performance
                            had been quite sluggish depending on the content.

                              I'd guess the idea is to make Glamor better with both Intel and AMD supporting it? Sharing the workload will only benefit everyone involved; if thats the case it's likely to end up bullet proof in the long run. They've still got some ways to go, but I imagine they're still working on it.
