From 04d2601426b0633bc817e57f44e087098bab2f84 Mon Sep 17 00:00:00 2001 From: Nicola Corna Date: Thu, 21 Jun 2018 14:57:26 +0200 Subject: sb/intel/common/firmware: Enable me_cleaner for Nehalem Recent patches in coreboot have fixed the freeze issues related to the use of me_cleaner on Nehalem. However, at least on the Lenovo X201, with me_cleaner some PCIe devices (like the SATA and USB controllers) disappear. In particular, setting the AltMeDisable bit ("-S" or "-s" flag) makes them disappear completely, while unsetting it makes them disappear only during cold boots. This kind of behaviour was already observed by Youness Alaoui on the Purism Librem laptops ([1]), and it seems related to some required board-specific PCIe configuration in the ME's MFS partition. For this reason, on the Lenovo X201, "-w EFFS" has been added to the me_cleaner arguments, which whitelists the MFS-equivalent partition for ME generation 2. This fixes all the issues, and the PCIe devices work as expected.
