Bug Description

Mesa 18.2.0 was recently released after several delays, but at least it doesn't have any known regressions on Intel hw. We tend to get the latest major version in the devel series ~2 weeks after FF, but since a month has passed now I thought it would be best to file an actual FFE request.

We'd also build it against LLVM 7, which is about to be released. Together these provide support for AMD Vega20 (kernel support still needed) among other things.

New features from mesa upstream reldocs:

OpenGL 4.3 on virgl
OpenGL 4.4 Compatibility profile on radeonsi
OpenGL ES 3.2 on radeonsi and virgl
GL_ARB_ES3_2_compatibility on radeonsi
GL_ARB_fragment_shader_interlock on i965
GL_ARB_sample_locations and GL_NV_sample_locations on nvc0 (GM200+)
GL_ANDROID_extension_pack_es31a on radeonsi.
GL_KHR_texture_compression_astc_ldr on radeonsi
GL_NV_conservative_raster and GL_NV_conservative_raster_dilate on nvc0 (GM200+)
GL_NV_conservative_raster_pre_snap_triangles on nvc0 (GP102+)
multisampled images on nvc0 (GM107+) (now supported on GF100+)

+1 from desktop team, we would like to see that update in cosmic

fwiw it's available on ppa:canonical-x/x-staging and I've been running a RC for some weeks now on my laptop without issues.

18.2.1 was released today and I'll push it there soon.

I would like to wait with this until the new 18.2.1 version builds. Could you perform some upgrade testing on it and leave a comment about how it went? I'll pick this up tomorrow and we'll decide then.

The LLVM 7 part seems like a separate thing though? Since it still doesn't seem to be available, I guess it would require another FFe/NEW, I suppose? Seems a bit bigger, especially so close to release.

LLVM 7 is the default in cosmic :)

and mesa 18.2.1 is built now, installs fine from the ppa

Duh, I blame the source naming change (previously it was llvm-toolchain-6.0, now it's just -7 instead of -7.0, ugh). Anyway, nevermind me!

I think I'm fine with the changes introduced and the testing so far. It's always better to have a more up-to-date stack. I also confirmed with Adam that we're ok with it. So: approving the FFe.
