AMD developer Marek Olšák continues leading their recent charge on looking to boost the performance potential out of Mesa / Gallium3D.
AMD's RadeonSI Gallium3D driver could soon be down to just two GL extensions left before seeing OpenGL 4.4 compliance.
Marek Olšák at AMD continues optimizing the RadeonSI Gallium3D driver for offering much better Linux gaming performance when using this open-source AMD graphics driver code. The latest are double-digit gains for at least the BioShock Infinite game.
Red Hat developer Rob Clark, the founder of the Freedreno driver for open-source reverse-engineered Qualcomm Adreno support, has made some significant performance optimizations to this Gallium3D driver.
Consulting firm Igalia who was contracted by Intel to help work on their open-source Mesa driver has written a blog post about some of the progress they've made the past year.
The latest work landing in Mesa Git has been for H.264 VA-API video encoding.
Marek Olšák of AMD has been working on some Gallium3D optimizations for boosting the performance of the popular BioShock Infinite game on Linux.
Thanks to work by AMD developers, there is support for accelerated H.264 video encoding with the VA-API implementation in Gallium3D.
For quite a while now Intel and Collabora developers have been working on an on-disk shader cache similar to what's offered by the NVIDIA proprietary driver for allowing GLSL shaders to be compiled and then cached on-disk, making it quicker to load the shaders in the future. It's looking like the Intel shader cache implementation may soon be ready for Git.
Just a few hours ago I was writing about NVIDIA making public the GP100 "Pascal" GPU firmware binaries needed for as a requirement for bringing up GeForce GTX 1000 series hardware acceleration on the open-source driver stack. Now the initial support has landed in Nouveau's NVC0 Gallium3D driver within Mesa for allowing 3D support.
Being half-way through the year now and also given the recent Mesa 12.0 release I decided to run some Git statistics on Mesa to see how this year is panning out for its development.
Timothy Arceri sent out the latest version of his Intel Mesa patches for the ARB_enhanced_layouts OpenGL extension. These patches finish up this last GL extension that's needed by this open-source Intel Linux driver before it can claim OpenGL 4.4 and then 4.5 compliance.
While we're already one week into July, Mesa 12.0 has been quietly riding well past its June release schedule.
Earlier this week there were some last minute AMDGPU DRM kernel patches submitted that were needed for AMD's imminent Radeon RX 480 "Polaris" launch while today some last minute Mesa patches have materialized.
Emil Velikov announced the release this morning of the fourth and final planned release candidate for Mesa 12.0.
Timothy Arceri of Collabora has prepped the latest version of his massive patch-set for providing an on-disk shader cache for Mesa, albeit focused for now on the Intel DRI driver.
The newest OpenGL extension now supported by Mesa is GL_EXT_window_rectangles.
Both the Intel i965 and AMD RadeonSI drivers within Mesa have seen separate work done over the past day for boosting the performance of compute shaders with these open-source OpenGL drivers.
Ahead of the official Mesa 12.0 debut later this month, Mesa release manager Emil Velikov of Collabora has announced 12.0 Release Candidate 2.
Marek Olšák posted a patch today to significantly boost the performance for games using multi-sample anti-aliasing (MSAA) on both the R600g and RadeonSI Gallium3D drivers.
If you've read Phoronix for any real length of time you've likely come across articles talking about Intel's Mesa driver and various work on the intermediate representations (IRs) of the driver. If you still are wondering about the Mesa driver's IR, here's a introductory blog post done by our friends at Igalia.
While Mesa 12.0 was just branched days ago and is going to be an extraordinary release, new work is already building up for Mesa 12.1-dev that will be released around September.
With the branching this week for the huge Mesa 12.0 milestone, here are some fresh Mesa 11.2 stable vs. Mesa Git benchmarks I ran today/yesterday with several graphics cards on Ubuntu 16.04 with the Padoka PPA for the updated Mesa Git stack plus also pulling down the Linux 4.6.0 stable release.
Enabling compiler Link-Time Optimizations (LTO) by default for Mesa in non-debug builds is being discussed in the name of performance and binary size.
With Mesa 12 now having been branched with plans to release next month, the code is under a feature freeze as developers turn to fixing bugs ahead of this stable release. With no more major features planned, here's an overview of the new features for Mesa 12.0.
Mesa release manager Emil Velikov has announced the first release candidate of Mesa 12.0, formerly known as Mesa 11.3.
With the main Mesa drivers (Intel, RadeonSI, NVC0) jumping ahead to OpenGL 4.3 and mostly done with OpenGL 4.4/4.5, plus Intel adding their Vulkan driver, and many other improvements over the past three months, the next stable release of Mesa is going to be massive.
Intel's Mesa Linux graphics driver is now officially at OpenGL 4.3 compliance.
Francisco Jerez of Intel was pushing his SIMD32 changes into Mesa Git over night and benefits the driver's ARB_compute_shader support.
Their drivers have basically been at OpenGL 4.3 compliance for a few days now, but today the switch was finally made where the Nouveau NVC0 and RadeonSI Gallium3D drivers are officially advertising OpenGL 4.3 support.
