AMD developer Marek Olšák has landed a "mega cleanup" to the Gallium3D Mesa state tracker code around its NIR intermediate representation handling.

AMD open-source developer Marek Olšák on Wednesday released libdrm 2.4.100 as the newest feature update to this Mesa DRM library.

Khronos president Neil Trevett was at this month's XDC2019 conference in Montreal and he clarified their position on accepting conformance submissions by the open-source drivers.

Mesa's TURNIP Vulkan driver that provides open-source Vulkan API support for Qualcomm Adreno hardware in recent weeks has been back to seeing new activity and this week more useful contributions are being made.

Back during the summer Eric Anholt who had been the lead developer of Broadcom's VC4/V3D graphics driver stack most notably used by Raspberry Pi boards left the company to join Google. In his place, the Raspberry Pi Foundation is working with consulting firm Igalia to continue work on the DRM/KMS kernel driver and Gallium3D drivers for this open-source graphics driver support.

Mesa's DRM library could soon be shifting to a date-based versioning scheme similar to what is already employed by Mesa itself (year.release) and the X.Org Server is also looking at similar versioning.

There still is another month until the feature freeze for Mesa 19.3 to end out 2019 and it will be a big one.

For the past year "Zink" has been in development as the OpenGL API implemented over Vulkan and done as a Gallium3D driver. That code by Collabora's Erik Faye-Lund will likely be merged to Mesa 19.3 in the coming weeks.

If you are a user of AMD Radeon RX 5700 "Navi" graphics and don't mind riding Mesa Git, the latest 19.3-devel code as of yesterday has several more GFX10 fixes/improvements.

Igalia is working on supporting OpenGL ES' GLSL marking of variables as "mediump" when the precision involving those variables can be lowered to half-float 16-bit registers. That in turn can help with performance when honoring that precision marking, which to date Mesa has ignored.

While there hasn't been too much to write on it in recent weeks, the Panfrost Gallium3D driver within Mesa for Arm Midgard/Bifrost graphics continues chugging along. The latest work on it is switching over to a new scheduler for Midgard.

One of the lesser known Vulkan drivers within Mesa is TURNIP but at least this week it's been seeing new activity after a recent lull of activity.

After a month worth of delays, Mesa 19.2 is now officially available as the latest quarterly feature update to this collection of open-source graphics driver components.

The Lima Gallium3D driver for supporting Arm Mali 400/450 graphics hardware within Arm SoCs has picked up a few performance optimizations.

It was just two days ago that Valve's performance-focused "ACO" shader compiler was submitted for review to be included in Mesa for the "RADV" Radeon Vulkan driver. Just minutes ago that new shader compiler back-end was merged for Mesa 19.3.

The third release candidate of the belated Mesa 19.2 is now available while a fourth and likely final RC is expected next week while the stable release of this quarterly Mesa3D update should be out at month's end.

Just a few weeks after Intel's i965 OpenGL driver in Mesa added GL 4.6 support, the "Iris" Gallium3D driver is now exposing OpenGL 4.6 support too.

Mesa 19.3 now supports the GL_MESA_EGL_sync extension, a feature proposed by Mesa developers themselves months ago for OpenGL.

Mesa 19.2 fell off the release train and is now likely to be released more towards the end of September rather than the middle of the month or even the end of August as was their original time-table.

Red Hat's David Airlie has been refocusing efforts recently on improving the state of the LLVMpipe driver that implements OpenGL / OpenGL ES on top of CPUs using LLVM. In the past few weeks he's been wiring up more GL4 / GLES 3.1 extensions and this morning the latest achievement is supporting OpenGL compute shaders!

As a follow-up to the recent story on AMD looking to land Navi 14 support in the imminent Mesa 19.2, that code for the smaller Navi GPU did successfully land into Mesa 19.3-devel and was back-ported to the 19.2 series for the upcoming 19.2.0 stable release.

A number of months have passed since having anything new to report on the progress of the LLVMpipe software driver, but David Airlie now has landed a number of improvements to this LLVM-leveraging "soft" OpenGL driver for Mesa 19.3.

Mesa's RADV Radeon Vulkan driver just saw a big performance optimization land to benefit APUs like Raven Ridge and Picasso, simply systems with no dedicated video memory.

This week saw OpenGL 4.6 support finally merged for Intel's i965 Mesa driver and will be part of the upcoming Mesa 19.2 release. Not landed yet but coming soon is the newer Intel "Iris" Gallium3D driver also seeing OpenGL 4.6 support.

Yesterday we shared that Mesa 19.2's release process would finally be getting underway with the first release candidate expected today following the code branching. Sure enough, that process began but now prominent Intel open-source graphics developer Jason Ekstrand is looking to get the OpenGL 4.6 support into this release.

Just hours ahead of the Mesa 19.2 feature freeze and days after the RadeonSI OpenGL driver added Renoir support, the RADV Vulkan driver has picked up support for this next-gen Zen 2 + Vega APU.

Mesa 19.2 was supposed to be branched marking its feature freeze two weeks ago on 6 August along with the issuing of the first release candidate. That milestone has yet to be crossed but should happen tomorrow.

AMD Mesa lead developer Marek Olšák has landed a set of improvements to the TGSI-to-NIR pass today for Mesa 19.2 to enhance the RadeonSI driver's support for using this intermediate representation.

Another set of patches was merged on Tuesday for the upcoming Mesa 19.2 to further along its Radeon "Navi" support within the RADV Vulkan driver.

Landing on Tuesday ahead of this week's Mesa 19.2 feature freeze is an experimental NIR compiler for the Etnaviv Gallium3D driver that provides open-source OpenGL driver support for Vivante graphics IP.
