Starting with Mesa 25.2, NVK will now advertise support for Blackwell (RTX 50xx series) and Kepler (most GT and GTX 600 series, most GTX 700 series, and some GTX 800 series) GPUs. On Blackwell, NVK supports Vulkan 1.4 while Kepler is stuck at Vulkan 1.2 due to hardware limitations. With this, NVK should support the same set of desktop GPUs as NVIDIA's proprietary driver ever has.
In theory, we've also mostly enabled Hopper since it sits between Ada and Blackwell in NVIDIA's GPU progression. However, since most NVK developers don't have access to any Hopper hardware, we haven't been able to test it, and there may be Hopper-specific issues. Since there are no Hopper-based consumer GPUs, this is unlikely to affect Linux users.
Blackwell users will also be getting OpenGL 4.6 support through Zink, just like the other Turing (GTX 16xx and RTX20xx series) and later GPUs do today. The old Nouveau GL driver does not have any support for Blackwell. Kepler users will still get the old Nouveau GL driver by default for now. We may still move pre-Turing GPUs to Zink eventually but that won't happen in this release.

In Nouveau some Tesla GPU could change clock settings as this project:

But with NVK, i cant read /sys/kernel/debug/dri/0/pstate.
