TrueNAS 25.10 now uses the NVIDIA open GPU kernel modules with the 570.172.08 driver. This enables TrueNAS to make use of NVIDIA Blackwell GPUs - the RTX 50-series and RTX PRO Blackwell cards - which many users have requested support for.
Unfortunately, what NVIDIA giveth, NVIDIA taketh away.
The NVIDIA 50-series Blackwell cards require the use of the new open GPU kernel module, but several of NVIDIA’s older generations of GPUs - including the Maxwell, Pascal, and Volta generations - lack the GPU System Processor (GSP) module on their silicon in order to leverage the open kernel module, and thus will no longer function. This includes the GTX 700-series, 900-GTX series, GTX 10-series, the Quadro M-series and P-series, and Tesla M-series and P-series cards.
This is to modify the official build parameters to remove the use of open GPU kernel module to be compatible with unsupported graphics cards.
Warning: for testing purposes only
You’ll need to replace the nvidia.raw file on your running TrueNAS system at /usr/share/truenas/sysext-extensions/nvidia.raw with the one you just compiled.
First, you need to make the /usr dataset writable:
zfs set readonly=off boot-pool/ROOT/25.10-BETA.1/usrOverwrite it!
cp nvidia.raw /usr/share/truenas/sysext-extensions/nvidia.rawThen, set the /usr dataset back to read-only:
zfs set readonly=on boot-pool/ROOT/25.10-BETA.1/usrAfter you’ve copied the file, simply run:
systemd-sysext merge
# Don't forget to restart docker service
systemctl restart docker
