Less than 24 hours after NVIDIA finally posted the signed firmware images for the GTX 900 "Maxwell" GPUs, Nouveau developers have succeeded in already getting 3D games running on their open-source driver stack.
It's been another exciting weekend of Mesa development activity by the independent developers working on the Nouveau driver for open-source NVIDIA Linux graphics support.
While all routine Phoronix readers should be well aware of the fact that there still isn't any open-source accelerated support for the GTX 900 "Maxwell" graphics cards yet as the Nouveau developers are blocked on waiting signed firmware from NVIDIA, the GTX 750 series does have some basic support as the original Maxwell GPUs. Here is a look at using this unofficial open-source driver on a GTX 750 with the Linux 4.5 kernel and Mesa 11.2-devel.
As a quick PSA, while you may be wanting to try out DRI3 support with the open-source NVIDIA (Nouveau) driver as it is capable of enhancing the performance, so far my latest attempts have been marred by rendering issues.
While I'm in the middle of a big Nouveau Linux 4.4 vs. Nouveau Linux 4.5 vs. NVIDIA proprietary driver comparison with multiple NVIDIA GeForce graphics cards, I just wanted to pass along a bit of good, non-performance news about Nouveau on Linux 4.5.
Karol Herbst has published a set of patches for implementing PMU engine counters, which will be needed for supporting dynamic re-clocking with newer GPUs.
With yesterday's NVIDIA GeForce GT 710 Linux testing was just the start of our tests for this sub-$50 USD graphics card powered by a cut-down Kepler GPU. Yesterday's article just included some basic NVIDIA binary driver tests while today's article includes Nouveau performance figures.
With the upcoming Linux 4.5 kernel, the process of manually re-clocking your NVIDIA graphics card using the open-source NVIDIA driver is slightly different compared to previous kernels.
Samuel Pitoiset has published a set of twelve patches for implementing compute shaders support within the Nouveau NVC0 Gallium3D driver for the GeForce 400/500 "Fermi" graphics processors.
Just a few days ago I was writing about OpenGL 4.4's Query Buffer Object Support Appears Nearly Ready For Nouveau and as of last night that code is now in Mesa Git.
While the Nouveau NVC0 and RadeonSI Gallium3D drivers were tied for a while in terms of their OpenGL 4 extension coverage, the NVC0 driver for NVIDIA Fermi GPUs and newer has advanced further with two more extensions -- one for OpenGL 4.2 and the other for OpenGL 4.3 -- now being supported by this open-source, reverse-engineered driver.
Hans de Goede of Red Hat and Pierre Moreau, an independent Nouveau contributor, are speaking at FOSDEM's graphics development room tomorrow about compute support for Nouveau.
Samuel Pitoiset sent out a set of 17 patches today that add the core of the compute shaders support to the Mesa state tracker as needed by Gallium3D drivers.
Karol Herbst, the independent open-source developer who has been focusing upon Nouveau re-clocking support in recent months, has made a new proposal and patch series concerning NVIDIA GeForce GTX 400/500 "Fermi" re-clocking on this open-source driver.
While it was looking like Nouveau might not have any big updates for Linux 4.5, a last-minute pull request was honored for DRM-Next that will provide some new/improved functionality to this open-source NVIDIA Linux kernel driver.
Ilia Mirkin has landed some more notable feature code into Mesa this evening.
With the Linux 4.2 kernel there was no feature update for Nouveau and it's looking like it might be that way too for Linux 4.5.
For the past few months a Samsung developer has been working on VA-API support for Nouveau. After a few patch revisions, that work is finally hitting mainline Mesa.
Support for altering the PCI Express speed with the Nouveau DRM driver is still being worked on for improving the open-source NVIDIA driver's performance.
The open-source Nouveau driver has hooked up support for OpenGL's relatively new ARB_shader_draw_parameters extension.
Following the latest Mesa and libdrm patches last week for allowing the Nouveau Gallium3D code to take advantage of the Nouveau DRM kernel driver's new interfaces, that work has now landed.
Prolific Nouveau contributor Ilia Mirkin has published a Gallium3D driver patch for implementing ETC2 and ASTC support on hardware supporting these texture compression methods.
Ben Skeggs has posted the latest revision of his libdrm and Mesa patch series for making use of the new "NVIF" kernel interface for the Nouveau DRM driver.
For the past few months a developer at Samsung has been working on VA-API support for the Nouveau Gallium3D driver. Those patches today are up to their fifth revision.
Ben Skeggs went ahead today and tagged version 1.0.12 of the Nouveau X.Org display driver.
Samuel Pitoiset who for years now has been working on the Nouveau driver and its performance counters support to be exact, has landed improved performance metrics handling for GeForce GTX 600/700 "Kepler" graphics cards.
Karol Herbst has sent out the latest version of his patches to further stabilize the re-clocking of GeForce 600/700 "Kepler" graphics cards.
Red Hat developer Hans de Goede was tasked earlier this year with working on the Nouveau driver for bettering the open-source NVIDIA Linux graphics driver. His latest focus has been on an LLVM TGSI back-end.
Just one week after Mesa Git received Nouveau NVC0 compute support, the NV50 Gallium3D driver for pre-Fermi GPUs has also received basic compute support.
The open-source Nouveau Gallium3D drivers have tacked on support for another OpenGL 4.4 extension.
