linux-firmware and microcode

to find what drivers are needed boot live iso with gui and dmesg to see firmware loaded


for i915 driver intel ice lake

see required latest drivers from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915

mine is icelake ( icl ) so  i select icl

mkdir /lib/firmware/i915
nano fw-i915

curl -O https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/i915/icl_dmc_ver1_09.bin
curl -O https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/i915/icl_guc_70.1.1.bin
curl -O https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/i915/icl_huc_9.0.0.bin

chmod +x fw-i915

./fw-i915

 

or manually download and move it to /lib/firmware/i915 filder

dmesg | grep microcode

cat /proc/cpuinfo | grep microcode | sort | uniq

printf "%x" 126

    The corresponding microcode file is 06-7e-05 located in /lib/firmware/intel-ucode/ (values in hexadecimal).

you can also get it using

lscpu | grep -e CPU.family: -e Model: -e Stepping: |               awk '{printf("%02x\n", $NF)}' | sed ':a;N;s/\n/-/;ta'
06-7e-05

find corresponding microcode file in
