This setting of the affinity leads to a performance regression
in streaming workloads which can be seen with e.g. by an
iperf streaming test between two LPARs using ConnectX-5
based nics.
In some tests the performance would

PCI Functions with UIDs >128 are currently not accounted correctly in the
s390x/pci code. Furthermore, the code allows that more than
CONFIG_PCI_NR_FUNCTIONS are created. This can lead to issues with data
structures which

Today, the enumeration of PCI functions on s390x does not reflect which
functions belongs to which physical adapter.
Layout of a PCI function address on Linux:

On s390x, each function is presented as

One of the PCI enhancements on Z15 are the enhanced PCI load/store instructions
which can be executed directly from user space code. When these instructions
are available and preexisting user space code still uses the old

With the introduction of CPU directed interrupts the kernel
parameter pci=force_floating was introduced to fall back to
the previous behavior using floating irqs.
Furthermore this fallback is used on machines lacking

Same issue here.

Status in
For older releases such as bionic we have one event:
UDEV [1304.304437] change /devices/virtual/block/bcache0 (block)
.ID_FS_TYPE_NEW=
ACTION=change
CACHED_LABEL=
CACHED_UUID=0192e0a7-9d8e-4771-9bb1-d730a2f66a9d
DEVLINKS=/dev/bcache/by-uuid/0192e0a7-9d8e-4771-9bb1-d730a2f66a9d
The good news is that the bcache events are reaching udev, however the
/usr/lib/udev/rules.d/60-persistent-storage.rules rules may need to be
modified to ignore bcache specific events.
