Subject: [PATCH v4 10/32] s390/pci: stash dtsm and maxstbl
Date: Mon, 14 Mar 2022 15:44:29 -0400 [thread overview]
Message-ID: <20220314194451.58266-11-mjrosato@linux.ibm.com> (raw)
In-Reply-To: <20220314194451.58266-1-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.
