With Linux 4.9 there is unfortunately no new feature code for Nouveau due to being late to merge the new functionality, but that work that missed 4.9 is now staged in DRM-Next for merging to mainline when the Linux 4.10 merge window rolls along.
The Nouveau DDX X.Org driver, xf86-video-nouveau, hasn't supported NVIDIA's GTX 750/900 Maxwell graphics processors even though there's been the reverse-engineered, open-source support within the Nouveau DRM kernel driver and NVC0 Gallium3D Mesa driver. Patches revised today implement Maxwell support for the X.Org driver.
It's not as important as NVIDIA publishing new signed firmware images, but then again it's not every day we see NVIDIA developers contribute to the open-source Nouveau driver stack. Nevertheless, today a new set of patches were published for the Nouveau DRM driver.
Thanks to the ongoing compute-focused work by independent Nouveau contributor Samuel Pitoiset, the NVC0 Gallium3D driver is the first driver in Mesa supporting the ARB_compute_variable_group_size extension.
In addition to the Nouveau status update talk at XDC2016, Nouveau contributor Karol Herbst had carried out an additional presentation on Friday dedicated to this open-source NVIDIA driver's work on power management and re-clocking.
Besides Nouveau developers being frustrated by NVIDIA's signed firmware blobs, at XDC2016 they also made other remarks about their focus on OpenGL and performance while Vulkan support isn't expected anytime soon.
The latest stable release of the Nouveau X.Org driver is now available for users of this open-source NVIDIA DDX component in conjunction with the Nouveau DRM kernel driver.
Nouveau developers Samuel Pitoiset, Karol Herbst, Pierre Moreau, and Martin Peres presented their status update on this open-source, reverse-engineered NVIDIA Linux graphics driver during the second day of the XDC2016 conference. Nouveau developers had a few words for the NVIDIA developers in the room.
Great news for users of the open-source NVIDIA "Nouveau" graphics driver: the long-awaited boost patches are now queued up to land with Linux 4.9.
For those with a TITAN X or other high-end GPUs that have a configurable light-up "GeForce" LED sign along the edge of the graphics card, a new Nouveau driver allows manipulating those LEDs.
Independent Nouveau developer Karol Herbst continues to be hard at work on improving the re-clocking state of the open-source NVIDIA Linux driver stack.
Samuel Pitoiset continues being one of the most prolific Nouveau driver developers in recent times and today posted support for OpenGL tessellation on NVIDIA Maxwell GPUs and newer.
In addition to the GeForce GTX 900 "Maxwell" open-source driver support on Nouveau being in rough shape due to lack of re-clocking / power management for allowing sufficient performance, the NVC0 Gallium3D driver for Maxwell has also lagged behind with some OpenGL 4.x features on the GTX 900 GPUs.
The Nouveau open-source NVIDIA DRM driver changes have been queued in DRM-Next for the Linux 4.8 kernel.
While there isn't yet any 3D/hardware acceleration support, the first milestone of open-source bring-up for the latest-generation NVIDIA GeForce GTX 1000 "Pascal" graphics processors is now available for Nouveau.
For users of Nouveau's NVC0 Gallium3D driver with a GeForce 400/500 "Fermi" graphics card, there is now OpenGL 4.2 compliance.
We've already covered at length the many AMDGPU/Radeon changes, the usual Intel DRM churn, and the multiple new DRM drivers coming for Linux 4.7. Missing from our coverage has been the Nouveau driver, but that work is finally getting queued up for this next kernel version.
Samuel Pitoiset's patches take the Nouveau NVC0 Gallium3D driver's support up to OpenGL 4.2 for GeForce 400/500 "Fermi" graphics cards.
Prolific Nouveau contributor Samuel Pitoiset has now enabled compute support by default for NVIDIA GK110 GPUs and newer.
It's an exciting day for users of Nouveau, the open-source NVIDIA Linux graphics stack, assuming you have a GK104 or GK110 GPU.
Karol Herbst has sent out his latest set of 37 patches for trying to improve volting and clocking on NVIDIA GeForce 400 "Fermi" GPUs and newer.
If you have a NVIDIA GeForce 600/700 "Kepler" graphics card and wish to help out the Nouveau driver developers by testing out the experimental "boost" re-clocking patches covered yesterday on Phoronix thanks to the work by Karol Herbst, here's a 4.5-based Ubuntu kernel build to try out this weekend.
As a result of comments made on the recent Intel's Unreleased 3.0 X.Org Driver Gets More Fixes For DRI3/Present article, a reader inquired to the Nouveau developers about the X.Org DDX driver options for open-source NVIDIA users on Linux.
With the exception of the GK110 graphics processor, NVIDIA's Kepler and Maxwell GPUs now support OpenGL compute shaders (GL_ARB_compute_shader) with the latest Nouveau driver code in Mesa.
With yesterday's Nouveau Kepler vs. Maxwell Performance On Linux 4.6 + Mesa 11.3-dev benchmarks, a number of Phoronix readers expressed their surprise how well the GeForce 600/700 "Kepler" series hardware was performing on the open-source Nouveau driver once manually re-clocking these graphics cards. It's certainly much better than the GTX 900 series performance on Nouveau as the Maxwell GPUs don't have any re-clocking support on Nouveau at all. I'm working on some fresh Nouveau vs. NVIDIA Kepler tests and for one Steam Linux game, this reverse-engineered NVIDIA open-source driver is able to beat out the "binary blob" from NVIDIA.
While it won't help the current GTX 900 Maxwell performance situation on Nouveau due to being blocked on the PMU firmware in order to be able to re-clock these latest-generation GPUs, there's a fresh kernel source tree that's easy to build with experimental Nouveau patches for improving the NVIDIA re-clocking support on this open-source driver.
Now that everything has been mainlined concerning the GeForce GTX 900 "Maxwell" support in the open-source Nouveau driver, it's relatively easy getting the hardware acceleration with OpenGL support running on this community-based, reverse-engineered Linux graphics driver.
The Nouveau driver updates for the Linux 4.6 merge window were staged on Sunday into the DRM-Next tree.
Samuel Pitoiset has been continuing in his performance counters / compute support quest for the Nouveau open-source NVIDIA driver. Samuel's latest accomplishment is landing MP performance counters for the GK110 GPUs.
Samuel Pitoiset continues carrying out compute miracles for the open-source Nouveau NVIDIA Linux graphics driver stack.
