Subject: [PATCH v3 09/30] s390/pci: export some routines related to RPCIT processing
Date: Fri, 4 Feb 2022 16:15:15 -0500 [thread overview]
Message-ID: <20220204211536.321475-10-mjrosato@linux.ibm.com> (raw)
In-Reply-To: <20220204211536.321475-1-mjrosato@linux.ibm.com>
KVM will re-use dma_walk_cpu_trans to walk the host shadow table and
will also need to be able to call zpci_refresh_trans to re-issue a RPCIT.
