Phoronix: Mesa DRI3 Picks Up GLX_EXT_buffer_age Support

The Direct Rendering Infrastructure 3 code for Mesa has picked up support for the GLX_EXT_buffer_age extension...

Note: GLX_EXT_buffer_age is supported in:

KWin 4.11.5 or newer

Thanks d2kx, was trying to track down a Kwin commit for buffer_age but couldn't

Unfortunatelly for Intel+Gnome it takes more

They surely take their time...

This has nothing to do with GNOME. GNOME is using the buffer_age extension since 3.8.
The mesa patches got merged all that's missing to get it working (with any application / desktop i.e not only GNOME) is a ddx driver that enables DRI3.

As for the article

There's also been Mesa code for the buffer-age extension since last year for DRI2 but now it's been brought into the DRI3 world.

This is wrong. GLX_EXT_buffer_age cannot work with DRI2.

The link this points to is talking about EGL_EXT_buffer_age which works for native EGL (i.e EGL on KMS / wayland) but not for EGL running on top of X11 and there is no support for GLX_EXT_buffer_age.

According to that, Gnome already supports the extension. They are waiting for Mesa and a DRI3 Intel driver like everybody else. . .

Adel Gadllah is a Gnome developer, if there was any reason for taking their time it's because they're busy implementing this extension for all.

what kind of opengl version concerns this implementation? Lubuntu (lxde) will take any advantage of this feature?

Then why the clutter patch is needed?

Nice!
Anyone knows what is needed for DRI3 to get used? Support in the various drivers?
