Title:
[22.04 FEAT] Enhanced Interpretation for PCI Functions on s390x -
kernel part
Status in Ubuntu on IBM z Systems:
Fix Committed
Status in linux package in Ubuntu:
Fix Committed
Bug description:
The PCI Passthrough implementation is based on intercepting PCI I/O
instructions which leads to a reduced I/O performance compared to execution of
PCI instructions in LPAR.
For improved performance the interpretive execution of the PCI store and PCI
load instructions get enabled.
Further improvement is achieved by enabling the Adapter-Event-Notification
