Firmware for NVIDIA graphics card support is included in the 6.7 branch of the Linux kernel. This solution will allow nouveau developers to not worry about reclocking for new graphics cards (starting with the 20xx (NV160 family (Turing) series of graphics cards up to the latest 40xx (Ada Lovelace))). By default, this feature will only be enabled for 40xx series graphics cards. However, if you want to try it for other generations of NVIDIA devices, you need to specify the parameter nouveau.config=NvGspRm=1 in the kernel boot parameters.
Quote from Nouveau developers:
Since the NVIDIA GSP firmware takes over the initialization and power management of the GPU, this should simplify the booting of future generations of NVIDIA graphics processors. It’s crucial that this should help improve power management / reclocking support for Nouveau drivers, which has not had good support since the GeForce GTX 700… However, do not expect Nouveau to suddenly become more performant compared to the proprietary driver.
There is a downside: this firmware contains even more closed-source blocks from NVIDIA that are necessary for our open driver. Worse yet, the firmware ABI is unstable; for example, the current NVIDIA driver code presented for Linux 6.7 is compatible with the firmware distributed as part of the NVIDIA R535 driver package.
Another piece of news from Nouveau: the NVK driver is now compatible with the Vulkan 1.0 specification. To work, it requires a recent kernel (no lower than 6.6) and mesa-git. It will work on graphics cards from the Turing generation up to Ada Lovelace. If you have a graphics card from earlier generations, you can try to run Vulkan in a test mode. There are no guarantees it will work; there may be artifacts and so on.
Example:
NVK_I_WANT_A_BROKEN_VULKAN_DRIVER=1 binary
Quote:
This means it passes all Vulkan 1.0 tests, but does not imply it's ready for Linux gamers/enthusiasts or that it’s a fast implementation. Not to mention that VKD3D-Proton requires support for at least Vulkan 1.3. Back in August, I published some initial tests of NVK. It has improved since then but is still not suitable for Linux gamers with modern games. Recently, the new NAK compiler has become another important step towards improved performance.
