Installing Google Coral TPU Gasket Driver on Debian with Kernel Linux 7.x

Google's official gasket-driver repository for Coral TPU support has been abandoned as of April 2026, breaking compatibility with Debian 13/Trixie running kernel 6.13+. A community-maintained fork now provides a pre-built DEB package and patched source code to fix the `MODULE_IMPORT_NS` macro change and `no_llseek` deprecation required for kernel 7.x compatibility.

Installing Google Coral TPU Gasket Driver on Debian with Kernel Linux 7.x Note: Google's official gasket-driver repo is now archived/abandoned as of April 2026. This guide uses the community-maintained fork. Why This Guide? The official gasket-driver from Google is abandoned. On Debian 13/Trixie with kernel 6.13+, the MODULE IMPORT NS macro changed and requires quotes: MODULE IMPORT NS "DMA BUF" instead of MODULE IMPORT NS DMA BUF . This guide shows how to patch and build it yourself. Prerequisites Install required packages sudo apt update sudo apt install -y git dkms build-essential linux-headers-$ uname -r Method 1: Pre-built DEB easiest Download the community-maintained package: wget https://github.com/feranick/gasket-driver/releases/download/1.0-18.4/gasket-dkms 1.0-18.4 all.deb sudo dpkg -i gasket-dkms 1.0-18.4 all.deb If it fails, try Method 2. Method 2: Build from Source recommended for kernel 7.x 1. Clone the repository git clone https://github.com/google/gasket-driver.git cd gasket-driver/src 2. Apply patches for kernel 6.13+ / 7.x php Fix no llseek - noop llseek sed -i 's/no llseek/noop llseek/g' gasket core.c Fix MODULE IMPORT NS for kernel 6.13+ sed -i 's/MODULE IMPORT NS DMA BUF /MODULE IMPORT NS "DMA BUF" /g' gasket page table.c 3. Build the package cd .. dpkg-buildpackage -us -uc -tc -b cd .. sudo dpkg -i gasket-dkms 1.0- .deb Verify Installation Check modules loaded lsmod | grep -E 'gasket|apex' Check TPU device ls /dev/apex 0 Check PCI device lspci -nn | grep -i apex Expected output: 04:00.0 System peripheral 0880 : Global Unichip Corp. Coral Edge TPU 1ac1:089a Troubleshooting "DMA BUF undeclared" You need the MODULE IMPORT NS "DMA BUF" patch. The kernel API changed in 6.13. "no llseek undefined" Apply the noop llseek patch or remove the .llseek = no llseek line. Clean previous failed installs sudo rm -rf /var/lib/dkms/gasket sudo apt purge gasket-dkms sudo dpkg --configure -a
