Subject: [PATCH v2 0/1] css: SCHIB measurement block origin must be aligned
Date: Fri, 19 Feb 2021 14:39:32 +0100 [thread overview]
Message-ID: <1613741973-3711-1-git-send-email-pmorel@linux.ibm.com> (raw)
Hi,
By testing Measurement with KVM unit tests I fall on this:
we forgot to test the alignment of the MBO for measurement format 1.
The last 6 bits of the MBO must be null, i.e. an aligned on 64 bytes
of the MBO, otherwise an operand exception is recognized when issuing
a msch instruction.
Regards,
Pierre
