Subject: [PATCH v5 09/21] s390/pci: stash dtsm and maxstbl
Date: Mon, 4 Apr 2022 13:43:37 -0400 [thread overview]

In-Reply-To: <20220404174349.58530-1-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.
