[v3,0/4] s390x/pci: some small fixes

Message

Matthew Rosato Dec. 3, 2021, 2:27 p.m. UTC

A collection of small fixes for s390x PCI (not urgent).  The first 3 are
fixes related to always using the host-provided CLP value when provided
vs a hard-coded value.  The last patch adds logic for QEMU to report a
proper DTSM clp response rather than just 0s (guest linux doesn't look
at this field today).

Changes for v3:
- Actually fix patch 4 this time (Pierre)

Matthew Rosato (4):
  s390x/pci: use a reserved ID for the default PCI group
  s390x/pci: don't use hard-coded dma range in reg_ioat
  s390x/pci: use the passthrough measurement update interval
  s390x/pci: add supported DT information to clp response
