Phoronix: AMD's Open-Source RadeonSI Driver Sees New Patches

It's been one year since AMD introduced their Radeon HD 7000 "Southern Islands" graphics cards, but the open-source RadeonSI Gallium3D driver for providing an open-source OpenGL driver for this latest-generation of AMD GPUs is still far from being in a readied state for AMD Linux customers...

I thought that RadeonSI mostly worked (including 3d), and needed testing and bug hunting?

It does mostly work already including 3D. The only requirement is a pre-1.13 xserver due to issues with glamor on newer xservers.

agd5f, isnt that counter-productive with Wayland coming (hopefully) soon? GLX is X-specific isnt it? I was under the impression that to go from X + mesa to Wayland + mesa just needed a recompile with the appropriate configure flag (source: https://aur.archlinux.org/packages/m...yland/PKGBUILD)

If the RadeonSI driver depends on GLX, wont it need to be patched to work on Wayland vs X respectively?

Or am I reading too far into this and misunderstanding the message?

Are you still sharing the results from piglit runs? If I remember correctly, results for r600/r600g where available somewhere at some point.

I think it's just the DDX driver which is using GLX. On Wayland, that won't even be used - it will just run straight off of Mesa.

So can it run Quake 3 and composited desktops then? Or is it just in the glxgears state right now?

I think this is saying that *glamor* depends on GLX. Wayland doesn't need X or glamor, so I think this should be OK.

That's my understanding as well.

From what I've learned by building the components myself (for r600), it's like this:
R600/SI depend on xf86-video-ati or xf86-video-modesetting as their DDX. xf86-video-ati depends on glamor. glamor depends on glx (or egl?).

If you're using wayland, you'll do:
R600/SI use Mesa to provide the EGL runtime. EGL is used by Wayland to render. No DDX/glamor required.
