FFe: Mesa 19.2.0

[Timo Aaltonen]

It would be great to get 19.2.0 in eoan, though it's release cycle has slipped. It's working fine on a typical desktop use here on i915 (Kaby Lake). It would also migrate to llvm-9.

It is currently at rc3, and final version is expected to arrive next week (week 39).

New features:

Full support for Intel Ice Lake
Support for AMD Navi

GL_ARB_post_depth_coverage on radeonsi (Navi)
GL_ARB_seamless_cubemap_per_texture on etnaviv (if GPU supports SEAMLESS_CUBE_MAP)
GL_EXT_shader_image_load_store on radeonsi (with LLVM >= 10)
GL_EXT_shader_samples_identical on iris and radeonsi (if using NIR)
GL_EXT_texture_shadow_lod on i965, iris
EGL_EXT_platform_device
VK_AMD_buffer_marker on radv
VK_EXT_index_type_uint8 on radv
VK_EXT_post_depth_coverage on radv
VK_EXT_queue_family_foreign on radv
VK_EXT_sample_locations on radv
VK_EXT_shader_demote_to_helper_invocation on Intel.
VK_KHR_depth_stencil_resolve on radv
VK_KHR_imageless_framebuffer on radv
VK_KHR_shader_atomic_int64 on radv
VK_KHR_uniform_buffer_standard_layout on radv

(note: iris is the new DRI driver for newer Intel, not enabled by default yet)

packages for testing: ppa:canonical-x/x-staging

1) Are you confident that you'll get enough testing to find any meaningful regressions, and have enough time to fix them before release?
2) Is there an upstream point release planned by October, or does their slip mean we'll see .1 as an SRU a month post-release?

I'm a tentative +1 on this anyway just for the Ice Lake and Navi support, which we'll also want for the next bionic point release, but better answers to the above would help me be sure.

Just tested 19.2 RC4 from the ppa on a Radeon RX 570.
Everything works fine, desktop and games (I've tested Witcher 3, CS:GO, HoN).

[Timo Aaltonen (tjaalton)]

1) yes, the upstream schedule slip has meant that .0 (which should be released tomorrow/the day after) is better than the usual .0 release

2) there will be a point release every two weeks, so the first one should arrive roughly around Oct 9th

[Adam Conrad (adconrad)]

Mmkay, based on the above, I say go for it. It'll miss beta (unless we have reason to respin, I guess), but such is life.
