To update the intel-ucode package to the system:
- 1. Ensure the existence of /sys/devices/system/cpu/microcode/reload
- 2. Copy intel-ucode directory to /lib/firmware, overwrite the files in /lib/firmware/intel-ucode/
- 3. Write the reload interface to 1 to reload the microcode files, e.g. echo 1 > /sys/devices/system/cpu/microcode/reload
