Arch Linux

It would be nice if someone could comment on that. Something like "currently no time", "not tested enough yet", "still working on it", etc. would also be nice. But being left alone is a little bit frustrating. Anyway, I've looked out a bit more and the following distros also enable it:

Debian (see EGL_DISPLAYS+=drm; they even include wayland as backend):
http://anonscm.debian.org/gitweb/?p=pkg-xorg/lib/mesa.git;a=blob;f=debian/rules;hb=HEAD

Ubuntu (see EGL_DISPLAYS+=drm; they even include wayland as backend):
http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/quantal/mesa/quantal/view/head:/debian/rules

Fedora (see --with-egl-platforms=x11,drm; they even include wayland as backend):
http://pkgs.fedoraproject.org/gitweb/?p=mesa.git;a=blob;f=mesa.spec;hb=HEAD

Gentoo (see --with-egl-platforms with "gbm" USE-flag):
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-libs/mesa/mesa-8.0.4.ebuild?view=markup

In fact, I am really looking hard to find a distro _not_ enabling it. This currently includes FreeBSD (but only because EGL did not build on BSD for a long time. They even consider adding it now):
http://www.freebsd.org/cgi/cvsweb.cgi/ports/graphics/libGL/bsd.mesalib.mk?rev=1.20;content-type=text%2Fplain

OpenSuse: build.opensuse.org is down for maintenance since several hours so I haven't found the build instructions, yet.

Mageia/Mandriva: Where the hell do they keep their build-files? Haven't found them, yet.


If you need more background information: using --with-egl-platforms=drm adds DRM as platform-driver for the EGL implementation of mesa. The EGL API is a Khronos API that replaces GLX with a platform-independent approach. Only the backends are platform dependent now. The X11 EGL backend is similar to GLX. The drm backend, though, provides EGL contexts based on linux DRM so we can directly render to framebuffers via OpenGL without the need of a window-system. This can even be used _with_ an existing window system in full-screen mode so we have zero-copy fullscreen apps (by passing the gbm buffer ID to the window-manager instead of blitting the whole window buffer into the frame-buffer; xorg doesn't support this, though).

A short list of other apps whose performance can be increase a _lot_ by using drm as egl-backend (that is, 3D rendering support): mplayer, wayland, kmscon, plymouth, ...5


There is actually no downside when enabling it. No additional dependencies, no other libraries/apps are affected (as long as drm is the second backend after x11, even though I don't know of any app using egl+x11), no performance drops, nothing. Hence, please consider adding it.


As a bonus adding wayland as EGL backend would be nice, too (as I said above, many other distros include it, too). However, this requires libwayland-client/server as dependencies and do not have a stable release, yet. So we have to wait some time for this. However, Kristian (Hoegsberg) announced that the protocol will see a stable release in August so this might be added in the near future, too.

Thanks!

I'll probably add it to the next mesa update. Meanwhile abs may be your friend.

for Mageia see:
http://svnweb.mageia.org/packages/cauldron/mesa/current/SPECS/mesa.spec?view=markup&pathrev=270724

Please check mesa 8.0.4-3 that will soon go into testing. I hope I've placed the new files into proper packages and location. Dependencies have changed a bit.

Thanks! Works like a charm.

i've tried to clean up a bit mesa meta package (for 9.0 release), you can find it here : http://pkgbuild.com/~lcarlier/mesa-git/sources/mesa-git/
