Description and Notes

The Quadro RTX 4000 is supported by both Nvidia’s proprietary driver and the open source Nouveau driver in the Linux Kernel.

You need to provide a physical x16 slot, and supplemental PCIe 6-pin power to give the card 140W of power.

There are two ways to try installing the driver:

Proprietary Nvidia driver

After flashing the 64-bit Pi OS beta to my Pi, I made sure to upgrade everything on it, and install the kernel source, so the Nvidia driver would compile:

sudo apt-get update
sudo apt-get -y dist-upgrade
sudo apt-get install -y raspberrypi-kernel-headers
sudo reboot

Now, download Nvidia’s latest AARCH64 Driver for ARM 64-bit processors, make the downloaded .run file executable, and run it with sudo:

chmod +x NVIDIA-Linux-aarch64-565.77.run
sudo ./NVIDIA-Linux-aarch64-565.77.run

Currently these cards all throw an error about ‘RmInitAdapter failed’… see the linked GitHub issue for more help.

Nouveau (open source) driver

To get the Nouveau driver loaded, you have to recompile the Linux kernel for Pi OS.

Go to Device Drivers > Graphics support on the menuconfig step, and select the Nouveau driver to install.

If you want to be able to boot the Pi all the way, make sure to blacklist the nouveau kernel module:

sudo nano /etc/modprobe.d/blacklist-nouveau.conf

# Put this inside the file and save it:
blacklist nouveau

Now, after a reboot, you can explicitly load the module and see what happens by following dmesg in another terminal session:

sudo modprobe nouveau

When I tried this, I got a kernel panic. See the linked GitHub issue for more details.
