Daniel Stone of Collabora has published a new set of 14 patches implementing DRI3 v1.1's modifiers support inside Mesa with support for EGL X11 and Vulkan X11/Wayland.

With Mesa 17.2 expected to be branched before the week is through, expect a lot of last-minute feature activity for new work getting into this next quarterly update for Mesa 3D.

A new version of libdrm is available today, the library that sits between the kernel Direct Rendering Manager and the user-space clients like Mesa and others. This libdrm 2.4.82 release is a bit more notable than some of the other point releases as it does have some interesting additions.

It's fabulous to see how promptly the Mesa Vulkan drivers are receiving support for new extensions.

Andres Gomez of Igalia has announced Mesa 17.1.5 as the newest point release to the current Mesa 3D stable series.

Valve developer Andres Rodriguez has sent out his third revision to the set of Mesa patches implementing the EXT_external_objects OpenGL extension.

Andres Gomez of Igalia is organizing the Mesa 17.1.5 point release to happen this week with numerous fixes to the open-source Linux graphics stack.

With a lot of work going in recently to Mesa's KHR_no_error implementation for being able to optionally disable some error checking/handling within the OpenGL stack for potentially some CPU savings, I did some fresh tests of this feature (also known as MESA_NO_ERROR) when having the Kabylake Pentium CPU installed for the earlier Mesa GL threading tests.

There is just over one week left until the Mesa 17.2 feature freeze and the Etnaviv developers are hoping some of their outstanding work will land in time.

Eric Anholt has written his usual weekly update concerning his happenings on the open-source graphics driver stack for the Raspberry Pi devices and other Broadcom-powered hardware.

Marek Olšák's work on OpenGL multi-threading is now ready for more wide-scaling testing and will be enabled on a whitelist-basis for games capable of benefiting from this approach.

Emil Velikov of Collabora has reiterated his release plans for Mesa 17.2 in making it the latest quarterly release to this growing 3D graphics stack.

Valve developer Andres Rodriguez has updated his patch-set for wiring in support for OpenGL External Objects (EXT_external_objects) into Mesa.

NIR expert Connor Abbott who is working for Valve this summer and in particular RADV Vulkan features has published a new patch series today that also confirms another upcoming Feral Linux game using Vulkan.

Eric Anholt has announced a new driver stack he's begun working on for Broadcom: VC5.

Nicolai Hähnle has published his updated massive patch-set for implementing an external NIR back-end in RadeonSI.

Andres Rodriguez of Valve has published initial support for the OpenGL EXT_external_objects within Mesa, the new GL extensions likely to be part of OpenGL 4.6.

Mesa 17.1.4 is now available as the newest stable point release for the Mesa 17.1 series.

We will likely be seeing more driver-specific per-application performance/workaround tuning within Mesa Gallium3D drivers moving forward.

As it's probably been one year or so since last trying out Epic Games' new Unreal Tournament game in public alpha and with today's update offering easier Linux access, I decided to try it out.

Rob Clark continues doing great work on the Freedreno Gallium3D driver for open-source, reverse-engineered Qualcomm Adreno graphics as well as the related MSM DRM driver for display support with Snapdragon SoCs.

Marek Olšák's changes to make Rocket League and Witcher 2 happy on the RadeonSI OpenGL driver are now in place.

Given the continued flow of KHR_no_error patches hitting Mesa 17.2 Git by Valve developers, here is a fresh comparison using the just-updated Padoka PPA with comparing the impact of using this support via the MESA_NO_ERROR=1 switch.

Marek Olšák has posted a set of five patches for fixing up one of the remaining rendering issues affecting RadeonSI and the other Gallium3D drivers in being able to correctly render the popular Rocket League game on Linux.

Valve's Linux developers continue working on lowering the CPU overhead of the RadeonSI Gallium3D driver.

Mesa 17.1.3 is now available as the latest stable point release to this important 3D user-space graphics stack.

It was just yesterday that bindless texture support landed in Mesa Git for RadeonSI while now Samuel Pitoiset who works for Valve's Linux graphics driver team has taken to other work.

Quite pleasant waking up today to find that in Mesa Git are the 70+ patches for implementing ARB_bindless_texture support within RadeonSI Gallium3D.

If you are running Intel Haswell hardware with integrated graphics and have been seeing hangs under Linux, you're not alone but a fix is in the works.
