So which of the 95 files under /lib/firmware/intel-ucode do I > specify? That's in addition to the 14 files I have for my amdgpu.
There may be a cleverer way, but this is how I have been doing it. Install sys-apps/iucode_tool. Run: # iucode_tool -S It will report the microcode signature for your CPU. For example, one of mine: iucode_tool: system has processor(s) with signature 0x000106e5 (Re)emerge sys-firmware/intel-microcode and capture all its output. Then search for the above signature, again from the same CPU, as an example, this matches: intel-ucode/06-1e-05 signature: 0x106e5 <== flags: 0x13 revision: 0x07 date: 2013-08-20 size: 7168 Add the first line above in your CONFIG_EXTRA_FIRMWARE and rebuild your kernel. -- Regards, Mick
