Stop fetching NPU firmware from AMD-hosted repo.radeon.com URLs and source the .sbin blobs exclusively from Ubuntu's linux-firmware package (stable, distro-mirrored URLs): - add extract_npu_firmware.sh to pull the amdnpu .sbin blobs out of the linux-firmware deb - Dockerfile: run extract_npu_firmware.sh so the firmware is baked into the image, and replace the driver's download_npufws() with an empty stub so the build never reaches repo.radeon.com (download_vtd_archives, used for the xrt-smi validate data, is left intact) - README: document installing the firmware on the host (the kernel driver loads it from the host's /lib/firmware/amdnpu) - add .gitattributes to force LF on *.sh (CRLF breaks the shebang of extract_npu_firmware.sh when COPYed into the container) Co-authored-by: Cursor <cursoragent@cursor.com>
Keep the inline comment to a short description of the line and move the rationale here. The driver's download_npufws() fetches the NPU .sbin firmware from AMD-hosted repo.radeon.com URLs, which are version-specific and prone to breakage. We replace it with an empty stub via sed so the build never reaches repo.radeon.com; the firmware instead comes exclusively from Ubuntu's linux-firmware deb (extract_npu_firmware.sh). download_vtd_archives, which fetches the data used by xrt-smi validate, is intentionally left intact.
