The Direct3D 9 state tracker could prove to be the most important project since the original release of the Mesa graphics library.
Linux desktop systems can now have working support for Microsoft's Direct3D 9 API via a new Gallium3D state tracker. Unlike the earlier Direct3D 10/11 state tracker for Gallium3D on Linux, this new code actually can run D3D9 games and at better performance than what's offered by Wine.
A set of twelve patches were published on Monday by an Intel OTC developer for allowing support for OpenGL layered rendering as needed for OpenGL 3.2 / GLSL 1.50 support.
With the arrival of sRGB frame-buffers support, the Gallium3D LLVMpipe software driver is nearly ready to advertise OpenGL 3.0 support and OpenGL 3.1 is also attainable.
With the release of Mesa 9.2 being a few weeks out, here's a current look at the OpenGL 3.x/4.x support levels within Mesa.
In the past few days after having delivered R600 Gallium3D benchmarks of the R600 SB back-end that is a new shader optimization back-end for the Radeon Gallium3D driver, here's some comparison benchmarks against the upcoming R600 LLVM back-end.
Mesa 9.2 is slated for release next month, which means its code will be branched soon, so here's a look at some of the exciting features that have been merged for this next Mesa open-source Linux graphics release.
The "Clover" Gallium3D state tracker to Mesa for providing OpenCL support can now be used with an ICD loader.
While the very exciting Mesa 9.2 release is expected next month and its code will be branched soon, one feature that looks unlikely to be merged in time is any support for Canonical's Mir Display Server.
Mesa 9.2 and the R600 Gallium3D shader optimization back-end can deliver some nice performance gains for various generations of AMD Radeon HD graphics cards.
This morning I posted new Radeon Gallium3D - Mesa 9.1 vs. Mesa 9.2 benchmarks, which showed the upcoming Mesa release performing nicely for AMD APU graphics. However, what is the performance like the software-based LLVMpipe driver that is commonly being used in fallback situations where there is no GPU hardware driver available? It's generally a lot faster now for handling OpenGL.
Ian Romanick announced the Mesa 9.1.4 release on Monday. Mesa 9.1.4 offers back-ported bug-fixes to the open-source graphics drivers, mostly affecting the Intel DRI driver along with two LLVMpipe driver fixes.
There's long been a need for QEMU/KVM to have guest 3D support for virtual machines (especially with more of the modern Linux desktops requiring OpenGL support) and Red Hat engineers have talked about such support previously, but now it looks like code is finally materializing.
An Oracle engineer is beginning to look at developing a Mesa-based graphics driver for their VM VirtualBox software that could be integrated into the mainline Mesa code-base.
More Mesa / Gallium3D patches out of Google have come about this month for improving the open-source graphics stack.
Being published this afternoon are benchmarks of the Gallium3D LLVMpipe software driver compared to Intel HD 4600 graphics on Mesa 9.2 Git when using an Intel Core i7 4770K. While this Intel "Haswell" CPU is faster than previous generations, it's still obviously best not relying upon LLVMpipe.
Freedreno, the reverse-engineered community-based open-source driver for Qualcomm Adreno graphics hardware, now has support for the newer A300 series of graphics cores as found in the Google Nexus 4.
The Lima driver is slowly but surely progressing for supporting ARM Mali graphics hardware in an open-source world. A Mesa driver has been started, their demo code can be faster than the binary driver, user-space memory management is being tackled, and evidently the management at ARM Holdings isn't too happy.
The Freedreno Gallium3D graphics driver that's a reverse-engineered incarnation of the Qualcomm Snapdragon driver, has support for the A320 graphics core coming along quite well. The A320 found in the Nexus 4 is now running the Freedreno 3D driver and can even handle bearing the load of the GNOME Shell desktop.
With Qualcomm's newer Snapdragon SoCs no longer having a 2D acceleration core for graphics, the Freedreno driver has implemented XA acceleration support within the reverse-engineered software for implementing 2D over the 3D engine via its Gallium3D driver.
For those that were turned on by the recent Radeon Gallium3D performance improvements found in Mesa 9.2 but are Intel Linux graphics users rather than AMD, there's good news too. Here's some benchmarks showing off nice Intel OpenGL performance improvements found with Mesa 9.2 for an ASUS Ultrabook with HD 4000 "Ivy Bridge" graphics.
Mesa 9.1.3 was released today to address some outstanding bugs back-ported from the current Mesa 9.2 development code.
Ian Romanick of Intel's Open-Source Technology Center has announced the immediate release of Mesa 9.1.2 for open-source graphics drivers.
Published this weekend was a very primitive back-end for LLVM that generates TGSI, the standard intermediate representation (IR) used by Mesa's Gallium3D drivers.
For many months there has been a "shader optimization" branch of Mesa/R600g that sought to rather noticeably boost the performance of the AMD R600 Gallium3D driver. While this work by Vadim Girlin didn't look like it would be merged, after being revived and cleaned-up, it might reach mainline Mesa/Gallium3D as a new performance-boosting option.
The RadeonSI Linux driver that supports the Radeon HD 7000 series and future HD 8000 series of graphics cards can now handle compressed textures and 2D tiling.
Early this morning I delivered benchmarks of the new Intel Gallium3D driver developed by a LunarG employee. Coincidentally, hours later, the developer has proposed merging this Gallium3D graphics driver for Sandy Bridge and Ivy Bridge hardware into mainline Mesa.
While the release of Mesa 9.2/10.0 is still a ways away, for those users of the Nouveau reverse-engineered open-source NVIDIA graphics driver, here are some early benchmarks for reference compared to the stable Mesa 9.0 and 9.1 series.
Patches were published on Friday for the ARB_separate_shader_object extension of the OpenGL 4.1 specification.
The Gallium3D HUD that makes it very easy to show various driver/hardware related real-time performance metrics on a heads-up display drawn over OpenGL applications, has already received a few improvements.
