This guide uses the community-maintained fork.**\n\nWhy This Guide?\n\nThe official `gasket-driver`\n\nfrom Google is abandoned. On Debian 13/Trixie with kernel 6.13+, the `MODULE_IMPORT_NS`\n\nmacro changed and requires quotes: `MODULE_IMPORT_NS(\"DMA_BUF\")`\n\ninstead of `MODULE_IMPORT_NS(DMA_BUF)`\n\n.\n\nThis guide shows how to patch and build it yourself.\n\n## Prerequisites\n\n```\n# Install required packages\nsudo apt update\nsudo apt install -y git dkms build-essential linux-headers-$(uname -r)\n```\n\n## Method 1: Pre-built DEB (easiest)\n\nDownload the community-maintained package:\n\n```\nwget https://github.com/feranick/gasket-driver/releases/download/1.0-18.4/gasket-dkms_1.0-18.4_all.deb\nsudo dpkg -i gasket-dkms_1.0-18.4_all.deb\n```\n\n## If it fails, try Method 2.\n\n## Method 2: Build from Source (recommended for kernel 7.x)\n\n### 1. Clone the repository\n\n```\ngit clone https://github.com/google/gasket-driver.git\ncd gasket-driver/src\n```\n\n### 2. Apply patches for kernel 6.13+ / 7.x\n\n``` php\n# Fix no_llseek -> noop_llseek\nsed -i 's/no_llseek/noop_llseek/g' gasket_core.c\n# Fix MODULE_IMPORT_NS for kernel 6.13+\nsed -i 's/MODULE_IMPORT_NS(DMA_BUF)/MODULE_IMPORT_NS(\"DMA_BUF\")/g' gasket_page_table.c\n```\n\n### 3. Build the package\n\n```\ncd ..\ndpkg-buildpackage -us -uc -tc -b\ncd ..\nsudo dpkg -i gasket-dkms_1.0-*.deb\n```\n\n## Verify Installation\n\n```\n# Check modules loaded\nlsmod | grep -E 'gasket|apex'\n# Check TPU device\nls /dev/apex_0\n# Check PCI device\nlspci -nn | grep -i apex\n```\n\nExpected output:\n\n```\n04:00.0 System peripheral [0880]: Global Unichip Corp. Coral Edge TPU [1ac1:089a]\n```\n\n## Troubleshooting\n\n### \"DMA_BUF undeclared\"\n\nYou need the `MODULE_IMPORT_NS(\"DMA_BUF\")`\n\npatch. The kernel API changed in 6.13.\n\n### \"no_llseek undefined\"\n\nApply the `noop_llseek`\n\npatch or remove the `.llseek = no_llseek`\n\nline.\n\n### Clean previous failed installs\n\n```\nsudo rm -rf /var/lib/dkms/gasket\nsudo apt purge gasket-dkms\nsudo dpkg --configure -a\n```\n\n", "url": "https://wpnews.pro/news/installing-google-coral-tpu-gasket-driver-on-debian-with-kernel-linux-7-x", "canonical_source": "https://grigio.org/installing-google-coral-tpu-gasket-driver-on-debian-with-kernel-linux-7-x/", "published_at": "2026-05-11 20:15:59+00:00", "updated_at": "2026-06-03 12:05:11.333499+00:00", "lang": "en", "topics": ["ai-chips", "ai-infrastructure", "ai-tools", "machine-learning", "artificial-intelligence"], "entities": ["Google", "Coral TPU", "Debian", "Linux", "gasket-driver", "DMA_BUF", "GitHub", "feranick"], "alternates": {"html": "https://wpnews.pro/news/installing-google-coral-tpu-gasket-driver-on-debian-with-kernel-linux-7-x", "markdown": "https://wpnews.pro/news/installing-google-coral-tpu-gasket-driver-on-debian-with-kernel-linux-7-x.md", "text": "https://wpnews.pro/news/installing-google-coral-tpu-gasket-driver-on-debian-with-kernel-linux-7-x.txt", "jsonld": "https://wpnews.pro/news/installing-google-coral-tpu-gasket-driver-on-debian-with-kernel-linux-7-x.jsonld"}}
