Mesa 19.3.3 Released With Many Fixes

While Mesa 20.0 will be entering its feature freeze this week and branching ahead of the stable release expected in about one month, for now the Mesa 19.3 series is the newest available for stable users.

Zink Is Moving Closer To OpenGL 3.0 Support Over Vulkan

Zink was one of the Mesa/Gallium3D innovations that saw mainline status in 2019 for offering OpenGL support atop Vulkan hardware drivers. While an interesting approach, so far only the dated OpenGL 2.1 support has been exposed but the Collabora-led effort is closing in on OpenGL 3.0 capabilities.

Mesa's Radeon R600 Gallium3D Driver Now Has NIR Support Under Review

Similar to the trend with other Mesa drivers, the Radeon R600g driver for supporting Radeon HD 2000 through Radeon HD 6000 series graphics cards has been seeing experimental work to introduce a NIR back-end for this modern intermediate representation. That R600 NIR support now has a merge request open meaning it could possibly land still for Mesa 20.0.

Mesa 20.0's LLVMpipe Now Supports Running OpenCL On The CPU

Mesa's LLVMpipe Gallium3D driver has long been about running OpenGL on GPUs as a software fallback / debug path but as of this morning in Mesa 20.0-devel there is now the experimental ability of having OpenCL support making use of OpenCL "Clover" with NIR for CPU-based execution.

Mesa's LLVMpipe Software OpenGL Driver Now Uses NIR By Default

Joining the NIR driver bandwagon recently was LLVMpipe adding support for this new intermediate representation. Now with that support having matured, Mesa 20.0-devel's LLVMpipe software OpenGL driver is switching to NIR by default in place of TGSI.

Mesa 19.3 Released With Big Updates For Intel's Open-Source Drivers, Valve ACO Option

After a few weeks worth of delays due to blocker bugs the release of Mesa 19.3 is out today as a big end-of-year upgrade to the open-source OpenGL and Vulkan drivers for Linux systems. Intel and AMD Radeon driver changes largely dominate the work as always but there is a growing number of embedded driver changes and other enhancements for this crucial piece to the open-source 3D ecosystem.

RadeonSI Driver Switches To NIR, Thereby Enabling OpenGL 4.6 By Default For AMD GPUs

Mesa 20.0 due out in Q1'2020 is now the magical release that is set to switch on RadeonSI NIR usage by default in place of the TGSI intermediate representation. What makes this IR switch-over prominent is that OpenGL 4.6 is then enabled by default on this open-source Gallium3D driver supporting Radeon HD 7000 series GPUs and newer.

ADriConf GUI Control Panel Support For Mesa Vulkan Drivers Is Brought Up

One of the most frequent complaints we hear from Linux gamers running open-source GPU drivers is over the lack of the hardware vendors supporting any feature-rich control panels like they do on Windows. There are many Linux driver tunables exposed by these open-source graphics drivers, but often they can only be manipulated via command-line options, environment variables, boot parameters, and other less than straight-forward means especially for recent converts from Windows and other novice Linux users. ADriConf has been doing a fairly decent job as a third-party means of helping to improve the situation and now there is talk of it supporting Vulkan driver settings.

Mesa Developers Weigh Renaming Gallium "State Tracker" To "API"

In addition to the discussion over potentially dropping non-Gallium3D drivers from Mesa or otherwise potentially forking a portion of the code, AMD's Marek Olšák made a separate proposal about renaming the Gallium3D "state tracker" concept to being "API" implementations.

Mesa Devs Discuss Potentially Dropping Non-Gallium Drivers Or Forking Code For Gallium

Longtime open-source AMD graphics driver developer Marek Olšák has kicked off a discussion over the possibility in the not too distant future of either dropping non-Gallium3D drivers from Mesa (and moving them off to a maintenance branch or the like) or forking some of Mesa's existing code to allow it to be better optimized for Gallium3D use-cases. Due to raised concerns, other possibilities are also being expressed like simply moving ahead with optimizing the Mesa code-base for Gallium3D at a cost of potentially hitting dead code more often with the classic drivers.

Mesa Adds Option For Changing Intel's OpenGL Driver Default

While originally Intel planned to transition their OpenGL driver default to the modern "Iris" Gallium3D driver rather than the longstanding "i965" DRI driver for Mesa 19.3, that was pushed back to Mesa 20.0 for introduction in Q1'2020. In aiming to make that revised milestone a reality, a new option has been added to Mesa 20.0 with the Meson build system for being able to indicate the Intel OpenGL driver preference.

Mesa 19.3-RC5 Brings RADV Secure Compile Update, Other Fixes

While Mesa 19.3.0 was supposed to be out last week, it didn't happen nor is it happening this week due to blocker bugs. Given the US holiday week, it's looking like Mesa 19.3's blocker bugs might not be cleared in time for releasing next week either, but in any case the Mesa 19.3 Release Candidate 5 is now available for testing.
