I am trying to upgrade the Intel microcode, on Acer Chromebook 14 Edgar running ~amd64 Gentoo following this guide: https://wiki.gentoo.org/wiki/Intel_microcode

when i try to generate the microcode cpio archive using sys-apps/iucode_tool, it seems that the iucode_tool can not select valid microcodes and nothing is written to /boot
Code:
# iucode_tool -S --write-earlyfw=/boot/early_ucode.cpio /lib/firmware/intel-ucode/*
iucode_tool: system has processor(s) with signature 0x000406c4
iucode_tool: No valid microcodes were selected, nothing to do...


I think the CPU is called Intel Braswell:
Code:
$ uname -a
Linux groterdanhetis 4.14.12-gentoo #8 SMP Sat Jan 6 19:59:22 CET 2018 x86_64 Intel(R) Celeron(R) CPU N3160 @ 1.60GHz GenuineIntel GNU/Linux

here is output of lspci -k

I am not using initramfs.
At this point i can not continue upgrading the Intel microcode on the Acer Chromebook 14 Edgar.

I apologize if i did not provide enough system information, feel free to ask about the system, i will try my best to provide the information needed.

It seems that intel haven't yet released a microcode for your cpu
Code:
# iucode_tool  -l /lib/firmware/intel-ucode/* | grep 406c4
#

or try also with
Code:
# iucode_tool -S -l /lib/firmware/intel-ucode/*

fedeliallalinea, thank you.

I will just wait till there will be upgrade one day.

I can not find the microcode with:
Code:
# iucode_tool -S -l /lib/firmware/intel-ucode/*
