Subject: [PATCH v7 43/72] x86/sev-es: Adjust #VC IST Stack on entering NMI handler
Date: Mon, 7 Sep 2020 15:15:44 +0200 [thread overview]
Message-ID: <20200907131613.12703-44-joro@8bytes.org> (raw)
In-Reply-To: <20200907131613.12703-1-joro@8bytes.org>
From: Joerg Roedel <jroedel@suse.de>
When an NMI hits in the #VC handler entry code before it switched to
another stack, any subsequent #VC exception in the NMI code-path will
overwrite the interrupted #VC handlers stack.
Make sure this doesn't happen by explicitly adjusting the #VC IST entry
in the NMI handler for the time in can cause #VC exceptions.
