The Set-Program-Parameter facility (also known as Load-Program-Parameter
facility) provides the LPP instruction used to load the program
parameter. We already implement that instruction in TCG, so add it to our

Note: Not documented in the PoP but in "The Load-Program-Parameter and

With the cssids unrestricted (commit "s390x/css: unrestrict cssids") the

pretty painless. But let's play nice and deprecate it first.

The default css 0xfe is currently restricted to virtual subchannel
devices. The hope when the decision was made was, that non-virtual
subchannel devices will come around when guest can exploit multiple
channel subsystems. Since the guests generally don't do, the pain
of the partitioned (cssid) namespace outweighs the gain.
Let us remove the corresponding restrictions (virtual devices
can be put only in 0xfe and non-virtual devices in any css except
the 0xfe -- while s390-squash-mcss then remaps everything to cssid 0).
At the same time, change our schema for generating css bus ids to put
both virtual and non-virtual devices into the default css (spilling over
into other css images, if needed). The intention is to deprecate
s390-squash-mcss. With this change devices without a specified devno
won't end up hidden to guests not supporting multiple channel subsystems,
unless this can not be avoided (default css full).
Let us also advertise the changes to the management software (so it can
tell are cssids unrestricted or restricted).
The adverse effect of getting rid of the restriction on migration should
not be too severe. Vfio-ccw devices are not live-migratable yet, and for
virtual devices using the extra freedom would only make sense with the
aforementioned guest support in place.
The auto-generated bus ids are affected by both changes. We hope to not
encounter any auto-generated bus ids in production as Libvirt is always
explicit about the bus id. Since 8ed179c937 ("s390x/css: catch section
mismatch on load", 2017-05-18) the worst that can happen because the same
device ended up having a different bus id is a cleanly failed migration.
I find it hard to reason about the impact of changed auto-generated bus
ids on migration for command line users as I don't know which rules is
such an user supposed to follow.
Another pain-point is down- or upgrade of QEMU for command line users.
The old way and the new way of doing vfio-ccw are mutually incompatible.
Libvirt is only going to support the new way, so for libvirt users, the
possible problems at QEMU downgrade are the following. If a domain
contains virtual devices placed into a css different than 0xfe the domain
will refuse to start with a QEMU not having this patch. Putting devices
into a css different that 0xfe however won't make much sense in the near
future (guest support). Libvirt will refuse to do vfio-ccw with a QEMU
not having this patch. This is business as usual.

When dispatching memory access to PCI BAR region, we must
look for possible subregions, used by the PCI device to map
different memory areas inside the same PCI BAR.
Since the data offset we received is calculated starting at the
region start address we need to adjust the offset for the subregion.
The data offset inside the subregion is calculated by substracting
the subregion's starting address from the data offset in the region.
The access to the MSIX region is now handled in a generic way,

There are two places where the same endianness conversion
is done.
Let's factor this out into a static function.
Note that the conversion must always be done for data in a register:
The S390 BE guest converted date to le before issuing the instruction.
After interception in a BE host:
ZPCI VFIO using pwrite must make the conversion back for the BE kernel.
Kernel will do BE to le translation when loading the register for the
real instruction.
After interception in a le host:
TCG stores a BE register in le, swapping bytes.
But since the data in the register was already le it is now BE
ZPCI VFIO must convert it to le before writing to the PCI memory.
In both cases ZPCI VFIO must swap the bytes from the register.

Provide HMP monitor command execution result as it would be seen
by user who established an HMP monitor session.
Currently many commands may silently fail without any sign of that.
This patch let this info to be printed once test is running in
verbose mode.
For the future it might be useful to fail the test if command has
failed, however it would require a bit of rework inside test
engine itself.
A simple example of silent failure without reporting it would to
add some non-existent HMP command into 'hmp_cmds' list. In this case
test will report it successfully passed without error.
