Subject: [PATCH 22/70] x86/boot/compressed/64: Setup GHCB Based VC Exception handler
Date: Thu, 19 Mar 2020 10:13:19 +0100 [thread overview]
Message-ID: <20200319091407.1481-23-joro@8bytes.org> (raw)
In-Reply-To: <20200319091407.1481-1-joro@8bytes.org>
From: Joerg Roedel <jroedel@suse.de>
Install an exception handler for #VC exception that uses a GHCB. Also
add the infrastructure for handling different exit-codes by decoding
the instruction that caused the exception and error handling.
Signed-off-by: Joerg Roedel <jroedel@suse.de>

Say yes to enable support for the encryption of system memory.
