NVIDIA GA103 Support Posted For Open-Source Nouveau Linux Driver
NVIDIA GA103 Support Posted For Open-Source Nouveau Linux Driver

Merged last year into the Linux kernel's Nouveau DRM driver was initial support for GeForce RTX 30 "Ampere" GPUs initially in the form of the GA100 and GA102 parts. That support for the moment is still limited to just mode-setting/display support with 3D still being tackled, but now a patch has been posted that rather trivially extends the support to cover the GA103 GPU too.

Open-Source NVIDIA "Nouveau" Driver Refactors Some Display Code For Linux 5.20
Open-Source NVIDIA "Nouveau" Driver Refactors Some Display Code For Linux 5.20

While AMD and Intel are busy with big graphics driver changes for each new version of the Linux kernel, the open-source NVIDIA "Novueau" kernel driver that is largely just worked on by Red Hat employees is just stumbling along. NVIDIA in May announced they are transitioning to an open-source kernel driver approach, but that current kernel driver is not in shape for upstreaming and due to the heavy use of the GPU System Processor (GSP) that source release hasn't been a huge help yet for the reverse-engineered Nouveau driver. With the upcoming Linux 5.20, Nouveau has some display patches.

Open-Source NVIDIA "Nouveau" Driver Sees Few Changes For Linux 5.20
Open-Source NVIDIA "Nouveau" Driver Sees Few Changes For Linux 5.20

There hasn't been much to report on lately for the reverse-engineered Nouveau driver providing open-source NVIDIA GPU driver support on Linux. Several recent Linux kernel series haven't even seen any Nouveau DRM/KMS driver pull requests with changes. For the upcoming Linux 5.20 cycle, a Nouveau set of changes were sent in today to DRM-Next but it's quite tiny.

Nouveau Begins Shifting Around Code For Use By New Driver - Vulkan And/Or New Driver

While the just talked about Nouveau beginning to land GeForce RTX 30 "Ampere" open-source support is exciting, as mentioned there still are hurdles to overcome for having good open-source NVIDIA driver performance on modern GPUs. So equally exciting news is that Nouveau has begun adapting some of their code into a standalone library so it can be used in the future by other new driver(s).

Nouveau Switches Over To NIR Backend By Default
Nouveau Switches Over To NIR Backend By Default

As part of Mesa preparing to drop its old GLSL to TGSI code path and routing more Mesa drivers through using the NIR intermediate representation, the Nouveau Gallium3D driver code has switched to using this modern IR by default.

Open-Source Driver Flips On OpenGL ES 3.1 For Select NVIDIA GeForce 200 Series GPUs

Sadly there isn't much to report on at this time around improved open-source "Nouveau" driver support for the recent GeForce RTX 20 and RTX 30 series while even the GTX 900 and GTX 1000 series graphics processors are in poor shape for this unofficial driver. But when it comes to the aging GeForce 200 series, select models there are finally seeing OpenGL ES 3.1 supported by this open-source driver.

Nouveau With Linux 5.12 Has ~5k L.O.C. Change In Preparing For Ampere
Nouveau With Linux 5.12 Has ~5k L.O.C. Change In Preparing For Ampere

With Linux 5.11 there is open-source Nouveau KMS support for Ampere GPUs -- just kernel mode-setting without any form of 3D acceleration. The actual hardware acceleration requires more work and also NVIDIA to release the necessary signed firmware binaries. With Linux 5.12 there still is no 3D acceleration but a big set of patches was merged as a step in that direction.

Open-Source "Nouveau" Driver Now Supports NVIDIA Ampere - But Without 3D Acceleration
Open-Source "Nouveau" Driver Now Supports NVIDIA Ampere - But Without 3D Acceleration

Patches were sent out today that provide the open-source Linux kernel "Nouveau" driver with support for NVIDIA GeForce RTX 30 series "Ampere" graphics cards. But at the moment there is no 3D acceleration and the developers are blocked still by signed firmware requirements, so it's basically just a matter of having kernel mode-setting display support.

Nouveau NVC0 Shader Disk Cache Lands For Speeding Up Game Load Times

Covered back in February was work for Nouveau's NVC0 Gallium3D driver to finalle make use of the Mesa on-disk shader cache functionality for speeding up game load times by allowing previously compiled GLSL shaders to be cached to disk. That work by Red Hat has finally been mainlined in Mesa 20.3.

Open-Source 3D/Compute Finally Materializing For NVIDIA Volta / Turing GPUs

The open-source Nouveau kernel driver has supported Volta GPUs for some time and since Linux 5.6 also supported open-source initialization of Turing GPUs for hardware acceleration. But missing for Volta and Turing has been the Mesa-side support for enabling 3D (OpenGL) and compute (OpenCL) functionality on these newer GPUs. That is finally changing with pending Mesa patches.

Open-Source NVIDIA/Nouveau Changes Submitted For Linux 5.8

There hasn't been too much to report on the open-source NVIDIA "Nouveau" kernel driver in some time since the enabling of Turing and no apparent progress on re-clocking to allow the graphics cards to hit their rated clock frequencies (the longstanding, number one limitation for this open-source driver), but some changes were sent in today for the upcoming Linux 5.8 kernel merge window.

Nouveau Display CRC Support Being Firmed Up Thanks To NVIDIA's Documentation

While waiting to see NVIDIA's new open-source play and ultimately how the re-clocking situation will get addressed for Nouveau so modern GeForce GPUs can work at their intended frequencies on this open-source Linux graphics driver stack, at least the display support has been getting into a more reliable state with CRC support on the horizon as a result of NVIDIA's already published documentation.

NVIDIA Posts Firmware Needed For Open-Source GeForce 16 Series Acceleration

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.

NVIDIA Format Modifiers Coming To Nouveau In 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.

Nouveau Finally Lands SPIR-V Support As Part Of OpenCL Push

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.

NVIDIA Bringing Up Open-Source Volta GPU Support For Their Xavier SoC
NVIDIA Bringing Up Open-Source Volta GPU Support For Their Xavier SoC

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.

The Open-Source NVIDIA "Nouveau" Driver Gets A Batch Of Fixes For Linux 5.3

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.

NVIDIA Firmware Blobs Get Updated To Help Some Pascal GPUs With Nouveau

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.

Nouveau NIR Support Lands In Mesa 19.1 Git

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.
