Subject: [GIT PULL 09/42] s390/pci: stash dtsm and maxstbl
Date: Thu, 21 Jul 2022 18:12:29 +0200 [thread overview]
Message-ID: <20220721161302.156182-10-imbrenda@linux.ibm.com> (raw)
In-Reply-To: <20220721161302.156182-1-imbrenda@linux.ibm.com>
From: Matthew Rosato <mjrosato@linux.ibm.com>
Store information about what IOAT designation types are supported by
underlying hardware as well as the largest store block size allowed.
These values will be needed by passthrough.
