Bug Description

Mesa 19.0.0 will be soon released, and we should get that for disco, and then follow point-releases until the last one is released (roughly next July, will need an SRU).

We'll also migrate it to use LLVM 8.

New features according to upstream release notes:

GL_AMD_texture_texture4 on all GL 4.0 drivers.
GL_EXT_shader_implicit_conversions on all drivers (ES extension).
GL_EXT_texture_compression_bptc on all GL 4.0 drivers (ES extension).
GL_EXT_texture_compression_rgtc on all GL 3.0 drivers (ES extension).
GL_EXT_render_snorm on gallium drivers (ES extension).
GL_EXT_texture_view on drivers supporting texture views (ES extension).
GL_OES_texture_view on drivers supporting texture views (ES extension).
GL_NV_shader_atomic_float on nvc0 (Fermi/Kepler only).
Shader-based software implementations of GL_ARB_gpu_shader_fp64, GL_ARB_gpu_shader_int64, GL_ARB_vertex_attrib_64bit, and GL_ARB_shader_ballot on i965.
VK_ANDROID_external_memory_android_hardware_buffer on Intel
Fixed and re-exposed VK_EXT_pci_bus_info on Intel and RADV
VK_EXT_scalar_block_layout on Intel and RADV
VK_KHR_depth_stencil_resolve on Intel
VK_KHR_draw_indirect_count on Intel
VK_EXT_conditional_rendering on Intel
VK_EXT_memory_budget on RADV

this is available on ppa:canonical-x/x-staging
though it's built with proposed enabled, so could need bits from there

what testing has happened / what are the risks?

The upstream release tracker probably helps showing that there's only one identified bug on the list, which is triggered by Intel's CI. AMD has something similar but not as comprehensive AIUI.

I've tested this on an Intel gen9 (coffee lake) gpu so far, AMD Ryzen/Vega Mobile is soon done

tested the ppa version (19.0 rc7) on AMD Ryzen / Vega Mobile now, works fine (desktop, glxgears, vkcube)
