In continuation of this morning's article about Valve Planning To Carry Mesa GL Thread Feature On SteamOS, Per-Game Features, it looks like the developers working for Valve on the open-source Linux graphics driver stack are looking to do more in the per-game profile space.
It's looking like Valve will begin carrying some out-of-tree patches for their Mesa packages they use on SteamOS.
Marek Olšák has posted a set of patches today to the Mesa mailing list and they should help some Linux games, at least Rocket League.
Mesa developer Thomas Helland is looking at reviving an old set of Mesa patches that could help out in some CPU-bound scenarios.
Marek Olšák volleyed the 26 patches needed for Mesa supporting threaded OpenGL dispatch onto the Mesa mailing list for some additional public review.
As a quick update to yesterday's article about RADV fast clears by default was being proposed, that change-over just happened in Mesa 17.1-devel Git.
Timothy Arceri of Collabora has sent out his latest patches to Mesa in regards to the ongoing work for shader caches. The 40 patches published over night do benefit RadeonSI and R600g.
Emil Velikov has kicked off the new release by announcing the third release candidate to the upcoming Mesa 17.0.
Four years ago Intel developers were working on a threaded OpenGL dispatch mechanism for Mesa, but it never ended up being merged. Now, prolific Mesa contributor and AMD developer Marek Olšák is looking to merge this code and clean it up.
When writing this week about ILO Gallium3D being dropped from mainline Mesa, a Phoronix reader asked if LunarGLASS would be the next thing to be removed from Mesa... But LunarGLASS never made it to mainline Mesa, though it still is in development.
Last week we reported that Collabora developer Timothy Arceri would be trying to support Mesa's OpenGL shader cache with RadeonSI while since then work has begun to materialize.
Waking up this morning, Mesa has been trimmed up by over 58,000 lines of code.
Mesa 13.0.4 was released today by Collabora's Emil Velikov while the Mesa 17.0 debut is still on track for later this month.
Eric Anholt continues working on the open-source VC4 graphics driver stack for adding additional features and improving the OpenGL performance of the Broadcom GPU on the Raspberry Pi.
While many Phoronix readers cringe when hearing "Imagination Tech" or "PowerVR" due to past Linux driver issues and the lack of a full-featured open-source driver, one of their developers is now requesting commit rights to Mesa.
Samuel Pitoiset, former Nouveau contributor who is now working for Valve on AMD open-source Linux driver optimizations, landed some improvements this morning in Mesa Git.
For older Intel i915~i945 graphics hardware, the Linux Mesa driver has exposed OpenGL 2.1 support while under Windows these ~12+ year old integrated graphics have only exposed OpenGL 1.4. Mesa now though might withdraw its OpenGL 2 support by default for older hardware on the i915 driver.
The RADV Mesa Radeon Vulkan driver has seen some code land in Mesa Git while other patches are being staged on Mesa-dev as January comes to an end.
The libdrm 2.4.75 library is now available as the important component sitting between the user-space drivers and the kernel DRM.
Within Mesa Git this morning is another feature flipped on for the RadeonSI Gallium3D driver: ARB_gpu_shader_int64.
The second release candidate is now available for the upcoming Mesa 17.0.
Timothy Arceri of Collabora is close to finally merging the massive OpenGL on-disk shader cache. A majority of that work is for common Mesa but for the initial work it's just been wired into Intel's i965 Mesa driver. But, fortunately, this Collabora developer is planning to wire up the GLSL shader cache for benefiting the RadeonSI Gallium3D driver.
Timothy Arceri of Collabora has updated the hardware agnostic portion of the on-disk shader cache patches.
Intel's Mesa driver is at OpenGL 4.5 compliance but there are many extensions still left to be implemented that haven't appeared in a formal OpenGL specification. One of those extensions now being implemented is ARB_transform_feedback_overflow_query.
Libdrm has some new patches this morning from a NVIDIA developer.
With Mesa 17.0 up to its release candidates and being under a feature freeze, I explored this morning how the size of the changes for Mesa 17.0 compare to earlier Mesa milestones.
The first release candidate of Mesa 17.0 (formerly known as Mesa 13.1) is now available for testing.
After a very exciting development cycle, Mesa 17.0 was branched yesterday, officially marking the end of feature development for this next Mesa release due out in February.
Adding to the list of Mesa 17.0 features is enough functionality in the reverse-engineered Etnaviv Gallium3D driver for running OpenGL 2.0 games.
Mesa 17.0 (formerly known as Mesa 13.1) was supposed to enter its feature freeze last weekend, but that milestone and branching of the code-base didn't happen due to last minute feature work.
