[FFe] Mesa 11.0.0

[Timo Aaltonen]

Mesa 11.0.0 will be released as follows:

August 21st 2015 - Feature freeze/Release candidate 1
August 28th 2015 - Release candidate 2
September 04th 2015 - Release candidate 3
September 11th 2015 - Release candidate 4/Mesa 11.0.0

so even rc1 will miss feature freeze, which is why this bug exists.

[Changes]
Wily has 10.6.3 (in proposed as of now), biggest new features compared to it are:
- support for new 'amdgpu' driver (to be merged)
- support for OpenGL 4.2 in core mesa
- VMware OpenGL 3.3 support
.
.

[Packaging status]
- snapshots pushed to debian git
- packaging updated when necessary
- builds & works

[Plan for testing]
- a snapshot will be uploaded to debian-experimental and canonical-x/x-staging ppa, call-for-testing sent once it's available
- piglit runs on most common hw (intel, radeon, nouveau)

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[RussianNeuroMancer (russianneuromancer)]

Maybe it's possible to take https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1481832 into account while building Mesa 11 packages?

[Jason Gerard DeRose (jderose)]

I've started testing the mesa 11 rc2 packages here:
https://launchpad.net/~canonical-x/+archive/ubuntu/x-staging

One issue I've hit is that with mesa 11 rc2 installed, Unity will no longer run under qemu (note I'm testing with an amd64 VM, Wily host and Wily guest).

Attaching the full unit7.log file, but my hunch is the key failure from the log is:

Compiz (opengl) - Fatal: glXQueryExtensionsString is NULL for screen 0

Thanks!

[Timo Aaltonen (tjaalton)]

[ 2.292] (EE) AIGLX: reverting to software rendering
[ 2.292] (EE) AIGLX error: dlopen of /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so failed (/usr/lib/x
86_64-linux-gnu/dri/swrast_dri.so: cannot open shared object file: No such file or directory)
[ 2.292] (EE) GLX: could not load software renderer

that's a valid reason for the failure, so the build is broken somehow

[Timo Aaltonen (tjaalton)]

-1ubuntu1~ppa2 should have it again

[Jason Gerard DeRose (jderose)]

Timo,

Awesome, thanks for the quick fix! I'll test it under qemu as soon as the builds are finished.

Thanks!

[Jason Gerard DeRose (jderose)]

Timo, 11.0.0~rc2-1ubuntu1~ppa2 seems shiny with Unity under qemu. Thanks!

[Jason Gerard DeRose (jderose)]

Quick question: mesa11 depends on libllvm3.7, but libllvm3.7 is still in universe.

Is there a plan to promote libllvm3.7 to main?

[Jason Gerard DeRose (jderose)]

Oops, never mind... I see that libllvm3.7 being in main is mentioned in the summary, sorry for the noise!

[Timo Aaltonen (tjaalton)]

I've reverted back to llvm-3.6 because 3.7 isn't going to be in main in wily. PPA has 11.0.0 now.

[mrl586 (mrl586)]

It is not possible use newest OpenGL features with llvm-3.6.

[Timo Aaltonen (tjaalton)]

yes, I know

[Jonathan Riddell (jr)]

Approved by me from release team as it would fix the important bug 1492037

[Timo Aaltonen (tjaalton)]

for the record, I've been running this on Intel BDW & SKL, and newer radeon for a few weeks without issues.

[Jason Gerard DeRose (jderose)]

Likewise, I've been doing extensive testing with mesa 11 from the x-staging PPA on Haswell, Broadwell, and Skylake hardware, haven't hit any issues.

Timo, when do you expect mesa 11 to at least hit wily-proposed? I'll admit it makes me a bit nervous that mesa 11 isn't in wily proper yet :D

[Timo Aaltonen (tjaalton)]

Uploaded, still building on arm

[Robert Hooker (sarvatt)]

I have been running it for a week on Ivybridge with no issues in a Unity environment as well.
