Linux firmware

Show used firmware packages

• How to know, which firmware packages do I need?
• Kernel docs: Dynamic debug

• Add dyndbg="func fw_log_firmware_info +p" to the kernel cmdline

Then after reboot list the packages with:

journalctl -b | sed -n 's;.*Loaded FW: \(.*\),.*;/usr/lib/firmware/\1.zst;p' | xargs pacman -Qoq | sort -u
