Register an ISA-side hfstsfd probe for supportedRCBA/FD2 generations so firmware-hidden HECI functions can be diagnosed.Reviewed by: kbowling, adrianDifferential Revision: https://reviews.freebsd.org/D58863 List of files: /freebsd/sys/dev/intel/hfsts.c Mon, 14 Sep 2026 00:05:01 +0200 Abdelkader Boudih <seuros@FreeBSD.org>
