A guest started with qemu-system-s390x -M s390-ccw-virtio,accel=tcg -cpu qemu,zpci=on -device virtio-net-pci (...) and a 4.15 kernel in the guest (needed because the requirement for ais was dropped with commit 48070c73058be6de9c0d754d441ed7092dfc8f12 Author: Christian Borntraeger Date: Mon Oct 30 14:38:58 2017 +0100 s390/pci: do not require AIS facility and we don't have a working ais with tcg yet), I get sensible output out of lspci. Looks much nicer now after implementing feedback from David (thanks!) Changes RFC->v2: - no need to check for the zpci feature in the helpers - SIC does not set a condition code - SIC also should not depend on zpci - use tcg magic to improve the code in translate.c - clear zpci feature from supported set for !CONFIG_PCI Cornelia Huck (2): s390x/tcg: wire up pci instructions s390x/cpumodel: allow zpci features in qemu model target/s390x/cpu_models.c | 6 +++ target/s390x/gen-features.c | 3 ++ target/s390x/helper.h | 9 ++++ target/s390x/insn-data.def | 15 ++++++ target/s390x/misc_helper.c | 109 ++++++++++++++++++++++++++++++++++++++++++++ target/s390x/translate.c | 101 ++++++++++++++++++++++++++++++++++++++++ 6 files changed, 243 insertions(+) -- 2.13.6
