Overall the Nouveau DRM updates for Linux 4.10 are significant after they missed out on any feature changes for Linux 4.9. Given all the churn, there's been a last minute pull into DRM-Next of some more fixes and other minor activity.
NVIDIA developer Alexandre Courbot has sent out his latest version of Nouveau DRM patches to carry out Secure Boot refactoring of the code for dealing with NVIDIA's signed firmware requirements for Maxwell GPUs and newer. But these latest patches come with a bit of a twist.
Samuel Pitoiset, one of the few significant contributors to the open-source NVIDIA Linux graphics stack particularly when it comes to the area of performance counters, has now enabled MP performance counters in the NVC0 Gallium3D driver for NVIDIA GTX 750/900 series Maxwell hardware.
Ben Skeggs of Red Hat has added initial support for the GP102 Pascal GPU to the Nouveau DRM driver.
Last week Nouveau DRM maintainer Ben Skeggs posted the initial atomic mode-setting patches for early testing of all this new KMS code. That code is indeed going to make it for Linux 4.10 with that work being pulled in overnight to DRM-Next.
A few days ago I wrote about Nouveau atomic mode-setting and DP MST patches while now DRM subsystem maintainer Ben Skeggs is soliciting more testing from the open-source NVIDIA community for trying these big changes to the Nouveau KMS driver.
We've known Nouveau DRM maintainer Ben Skeggs of Red Hat has been working on atomic mode-setting and DisplayPort Multi-Stream Transport (DP MST) for this open-source NVIDIA Linux driver as that what led to Nouveau having no feature additions for Linux 4.9. Some of this code is now having the Nouveau kernel development tree.
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.
