Last week there were a bunch of new improvements and features for the open-source kernel graphics/display drivers merged for Linux 5.7. There were not any feature changes on the open-source NVIDIA "Nouveau" driver front while this week at least are some fixes/workarounds so it's less buggy for some hardware.

As written about last week, in the works for the Linux 5.7 kernel this spring is open-source NVIDIA "Nouveau" acceleration for the GeForce 16 series. That code is currently sitting in the Nouveau development tree until landing in DRM-Next for Linux 5.7, but NVIDIA has now posted the necessary firmware binaries needed for enabling the hardware acceleration on these Turing GPUs.

While the open-source Intel and Radeon OpenGL drivers within Mesa have long employed an on-disk shader cache to help with game load times by being able to load previously compiled shaders from disk, the Nouveau "NVC0" Gallium3D driver is on the heels of finally seeing similar support.

With the big Linux 5.6 kernel on the open-source NVIDIA "Nouveau" driver side there is finally accelerated support for the GeForce RTX 2000 "Turing" graphics cards (when paired with binary-only microcode). With that initial cut support is no GeForce 16 series Turing support, but that is now on-deck for Linux 5.7.

Now that the merge window is over for Linux 5.6, where the Nouveau open-source NVIDIA driver managed GeForce RTX 2000 "Turing" series accelerated support, a new feature addition landed Monday in the Nouveau kernel development tree for the next cycle.

Red Hat's Karol Herbst spoke at the FOSDEM 2020 conference in Brussels on the state of the open-source NVIDIA "Nouveau" Linux graphics driver stack.

Here is another big feature coming for Linux 5.6: the Nouveau driver will have initial accelerated support for NVIDIA "Turing" GPUs! This is coming at long-last with NVIDIA set to release publicly the Turing firmware images needed for hardware initialization.

Shortly before Christmas were a couple open-source Nouveau driver patches volleyed by NVIDIA. Some of that work is now queuing in the Nouveau DRM tree ahead of the Linux 5.6 merge window.

For the imminent Linux 5.5 kernel cycle we have talked about exciting AMD Radeon and Intel graphics driver changes on deck from Navi OverDrive overclocking to more Intel Tiger Lake and Jasper Lake bits, AMDGPU HDCP support, and other features queued. But what about the open-source NVIDIA "Nouveau" Linux driver?

Going back to December 2017 we've been tracking the Red Hat led effort on improving Nouveau's OpenCL compute support that involves adding NIR/SPIR-V support and improvements to the Clover Gallium3D state tracker. To much surprise, this morning the SPIR-V support for this open-source NVIDIA driver was merged for Mesa 19.3.

While NVIDIA doesn't contribute much open-source Linux driver code as it concerns their desktop GPUs (though they have been ramping up documentation), when it comes to Tegra/embedded is where they have contributed improvements and new hardware support to Nouveau and associated driver code in the past several years. NVIDIA's open-source Tegra/embedded contributions come as a result of customer demand/requirements. Their latest work is preparing to finally bring-up the "GV11B" Volta graphics found within last year's Tegra Xavier SoC.

While NVIDIA recently began publishing more hardware documentation, don't expect it to make an immediate difference in the quality of the open-source NVIDIA "Nouveau" driver. Today the pull request was sent to DRM-Next of the Nouveau kernel driver changes for the upcoming Linux 5.4 cycle and there isn't much to get excited about.

With last week's big DRM pull request for Linux 5.3 that brought Navi support most notably on the AMD side while Intel received HDR display support, continued Icelake/Gen11 work, and more, there weren't any changes to the open-source NVIDIA "Nouveau" driver. It was another unfortunate cycle of no major improvements for the Nouveau driver but at least sent out today were a set of new "fixes" for this driver that remains crippled on Maxwell GPUs and newer.

Building off the initial Turing mode-setting bits that were in place since Linux 5.0 and have continued stepping along to support newer variants on successive kernel releases, the Linux 5.3 kernel is slated to add support for the TU116 graphics processor.

If you are a user of the open-source NVIDIA "Nouveau" Linux graphics driver on laptops and have found no audio support, that is likely to be fixed by an upcoming kernel patch that should make its way to the Linux 5.3 kernel.

An updated firmware configuration should help some GeForce GTX 1000 "Pascal" users with their limited open-source driver support, but the situation remains a mess. Besides the fact of being binary blobs, it's more complicated this time around with the interfaces changing for what is expected by the Nouveau DRM kernel driver.

Following last week's big feature update to the DRM graphics drivers, an initial batch of "fixes" has now been merged to the early Linux 5.2 development code for these Direct Rendering Manager drivers.

While it missed the main DRM pull request for Linux 5.2, the Nouveau DRM driver now has initial support for NVIDIA's Turing TU117, the GPU powering the new GeForce GTX 1650 series.

Nouveau DRM maintainer Ben Skeggs at Red Hat has sent in the changes targeting the upcoming Linux 5.2 kernel.

It shouldn't come as any surprise, but landing today in Mesa 19.1 Git is the initial support for the Nouveau Gallium3D code to make use of the NIR intermediate representation as an alternative to Gallium's TGSI.

The work done by Red Hat's Karol Herbst over the past year for plumbing in NIR intermediate representation support within the open-source NVIDIA "Nouveau" Gallium3D driver will finally be landing.

Ben Skeggs, the Nouveau DRM maintainer employed by Red Hat, has sent in the big batch of open-source NVIDIA driver changes slates for the upcoming Linux 5.1 kernel.

The Nouveau kernel driver has queued patches for introducing Shared Virtual Memory (SVM) support for this open-source NVIDIA driver as a step forward to its OpenCL/compute opportunities.

The Nouveau kernel driver tree where development happens on this open-source NVIDIA DRM driver saw a fresh batch of changes on Tuesday in aiming for new material with Linux 5.1.

Longtime open-source NVIDIA "Nouveau" developer Ilia Mirkin has released xf86-video-nouveau 1.0.16 as the latest version of this X.Org DDX driver.

Among the many Linux 5.0 kernel features is initial open-source NVIDIA driver support for the latest-generation Turing graphics processors. Missed out on during the Linux 5.0 merge window was "TU102" support but now that is coming down as a fix for the 5.0 kernel.

Google developers working on the Chrome/Chromium web-browser have decided to blacklist the Nouveau driver from having GPU acceleration by default within their web-browser.

Longtime Nouveau contributor Ilia Mirkin has done some holiday hacking on this open-source NVIDIA driver and enabled support for another OpenGL extension in NVC0 Gallium3D.

Just in time for the upcoming Linux 4.21 kernel, the developers working on the reverse-engineered, open-source support for NVIDIA GeForce RTX "Turing" GPUs have published their preliminary code. But before getting too excited, there isn't GPU hardware acceleration working yet.

While at the start of the year Nouveau developers expressed their hope to create a basic open-source NVIDIA Vulkan driver this calendar year, it doesn't look like it's panning out.
