Subject: [pve-devel] [PATCH pve-kernel] d/rules: disable CONFIG_GDS_FORCE_MITIGATION
Date: Fri, 18 Aug 2023 13:35:08 +0200	[thread overview]
Message-ID: <20230818113508.1614200-1-s.ivanov@proxmox.com> (raw)

when not having installed an intel-microcode version containing the
mitigation, this options disables AVX instructions, which breaks quite
a lot of software (e.g. firefox, electron apps)

Reported-by: Stefan Hanreich <s.hanreich@proxmox.com>

quickly build a kernel with this and Stefan tested his reproducer from
yesterday without an updated microcode.
