Phoronix: GLX_EXT_buffer_age Patches For Mesa DRI2

While there have been GLX_EXT_buffer_age patches for Mesa going back months, they've been for DRI3. Chris Wilson of Intel has now implemented GLX_EXT_buffer_age support along the DRI2 code-paths...

Wut on first sight this sounds like intel wants to drop DRI3 altogether

Sounds to me more like they're making a hack that can be backported for systems with only DRI2 tbh

Well dunno about that... back in november, DRI3 was disabled by default in intel ddx and still is:

Yeah also together with info that Keith recently joined HP and with coming FreeSync monitors... it sounds better to stay with DRI2 and improved it.

Only if those have something to do with GLX_EXT_buffer_age extension, as it is X extension that is not required by the GL specs... those links are only about extensions *required* for OpenGL version bump in certain drivers - you will not see GLX_EXT_buffer_age listed there.
