This patchset exploits the VFIO ZPCI CLP region, which provides hardware
information about passed-through s390 PCI devices that can be shared with
the guest.
The retrieval of this information is done once per function (and for a
subset of data, once per function group) and is performed at time of device
plug. Some elements provided in the CLP region must still be forced to
default values for now to reflect what QEMU actually provides support for.
The original work for this feature was done by Pierre Morel.
Note: This patchset will overlap with "s390x/pci: Accomodate vfio DMA
limiting" because they both add hw/s390x/s390-pci-vfio.* - This is
intentional as both patchsets add functionality that belongs in these new
files. Once one set is taken, I'll rebase the other on top of it.
Associated kernel patchset:
https://marc.info/?l=kvm&m=160052933112238&w=2
Matthew Rosato (4):
update-linux-headers: Add vfio_zdev.h
linux-headers: update against 5.9-rc5
s390x/pci: clean up s390 PCI groups
s390x/pci: get zPCI function info from host
Pierre Morel (3):
s390x/pci: create a header dedicated to PCI CLP
s390x/pci: use a PCI Group structure
s390x/pci: use a PCI Function structure

vfio_zdev.h is used by s390x zPCI support to pass device-specific
CLP information between host and userspace.

To have a clean separation between s390-pci-bus.h and s390-pci-inst.h
headers we export the PCI CLP instructions in a dedicated header.

We use a S390PCIGroup structure to hold the information related to a
zPCI Function group.
This allows us to be ready to support multiple groups and to retrieve
the group information from the host.

Add a step to remove all stashed PCI groups to avoid stale data between
machine resets.

We use a ClpRspQueryPci structure to hold the information related to a
zPCI Function.
This allows us to be ready to support different zPCI functions and to
retrieve the zPCI function information from the host.

We use the VFIO_REGION_SUBTYPE_ZDEV_CLP subregion of PCI_VENDOR_ID_IBM to
retrieve the CLP information the kernel exports.
To be compatible with previous kernel versions we fall back on previous
predefined values, same as the emulation values, when the region is not
found. If individual CLP feature(s) are not found in the region, we fall
back on default values for only those features missing from the region.
This patch is based on work previously done by Pierre Morel.

Looks sane; but I wonder whether we should move the stuff under

I think you made the identifiers a bit too compact :)
s390_group_create() is not that long, and I have no idea what the 'ug'
(ugh :) parameter is supposed to mean.

No objection to the patch in general.

Probably. I'd be fine with creating this file under include, but if
we're going to do that we should plan to move the other s390-pci* ones
too. For this patchset, I can change this patch to put the new header
in include/hw/s390x, easy enough.
I'll plan to do a separate cleanup patchset to move s390-pci-bus.h and
s390-pci-inst.h.
How would you like me to handle s390-pci-vfio.h (this is a new file
added by both this patch set and 's390x/pci: Accomodate vfio DMA
limiting') -- It seems likely that the latter patch set will merge
first, so my thought would be to avoid a cleanup on this one and just
re-send 's390x/pci: Accomodate vfio DMA limiting' once the kernel part
hits mainline (it's currently in linux-next via Alex) with
s390-pci-vfio.h also created in include/hw/s390x (and I guess the
MAINTAINERS hit for it too). Sound OK?
