Can you tell how did you managed to know which microcode file kernel is searching for?

Yesterday OpenBSD-current had previous Intel firmware from November. Today it has firmware released in march. It should contain Spectre fixes for Sandy and Ivy Bridge, Haswell and so on, but probably mitigations need also OS kernel counterparts to be effective, which at the moment OpenBSD does not have.

Meltdown and Spectre PoC for OpenBSD. This is not mine. Use at your own risk.

Had you asked me two months ago, I might have remembered. I will have to guess: keyword searching, probably in /sys/arch/amd64.
