[Mesa-announce] Mesa 12.0.2 release candidate

Thu Sep 1 14:25:07 UTC 2016

Hello list,

The candidate for the Mesa 12.0.2 is now available. Currently we have:
 - 160 queued
 - 9 nominated (outstanding)
 - and 1 rejected patches

The current queue fixes crashes in GLX, EGL and Wayland-EGL, resolves
a number of
memory leaks in the video decoding drivers, makes the Intel Vulkan driver more
robust by exporting only the required symbols (previously we would get symbol
collisions leading to strange behaviour or even crashes).

>From Android side of things a deadlock and various memory leaks have been fixed.

Not to mention the steady amount of driver fixes in i965, nouveau, radeonsi,
freedreno and vc4.

Take a look at section "Mesa stable queue" for more information.

Ilia Mirkin (1):
      a4xx: make sure to actually clamp depth as requested

Ilia, for the above we require the 700+loc 9f219c7047b ("freedreno: add
batch-cache and batch reordering") and maybe more. Can you cross-check if
that's the case and send over a less evasive backport.
