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.

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.

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.

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.
