## GDDR6/GDDR6X GPU Memory Temperature Reader for Linux

Reads GDDR6/GDDR6X VRAM memory temperatures from multiple supported NVIDIA GPUs found in a host Linux system.
These findings are based on reverse engineering of the NVIDIA GPU Linux driver.

## Dependencies
- libpci-dev 
```
sudo apt install libpci-dev -y
```

- Kernel boot parameter: iomem=relaxed
```
sudo vim /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iomem=relaxed"
sudo update-grub
sudo reboot
```

## Clone & Run
