Note that we can only boot into secure mode from normal mode, i.e. stfle 161 is not active in secure mode. The other changes related to data gathering for emulation and disabling addressing checks in secure mode, as well as CPU resets. v5: * Added balloon inhibition * Moved docs into docs/system * Some more enable/disable changes * Moved enablement/disablement of pv in separate functions * Some review fixes v4: * Sync with KVM changes * Review changes V3: * Use dedicated functions to access SIDA * Smaller cleanups and segfault fixes * Error reporting for Ultravisor calls * Inject of RC of diag308 subcode 10 fails V2: * Split out cleanups * Internal PV state tracking * Review feedback Christian Borntraeger (1): s390x: Add unpack facility feature to GA1 Janosch Frank (17): s390x: Use constant for ESA PSW address Sync pv s390x: protvirt: Add diag308 subcodes 8 - 10 s390x: protvirt: Support unpack facility s390x: protvirt: Add migration blocker s390x: protvirt: Handle diag 308 subcodes 0,1,3,4 s390x: protvirt: Inhibit balloon when switching to protected mode s390x: protvirt: KVM intercept changes s390x: Add SIDA memory ops s390x: protvirt: Move STSI data over SIDAD s390x: protvirt: SCLP interpretation s390x: protvirt: Set guest IPL PSW s390x: protvirt: Move diag 308 data over SIDAD s390x: protvirt: Disable address checks for PV guest IO emulation s390x: protvirt: Move IO control structures over SIDA s390x: protvirt: Handle SIGP store status correctly docs: Add protvirt docs docs/system/index.rst | 1 + docs/system/protvirt.rst | 57 +++++++++++ hw/s390x/Makefile.objs | 1 + hw/s390x/ipl.c | 82 +++++++++++++++- hw/s390x/ipl.h | 33 +++++++ hw/s390x/pv.c | 106 +++++++++++++++++++++ hw/s390x/pv.h | 34 +++++++ hw/s390x/s390-virtio-ccw.c | 143 +++++++++++++++++++++++++++- hw/s390x/sclp.c | 17 ++++ include/hw/s390x/s390-virtio-ccw.h | 1 + include/hw/s390x/sclp.h | 2 + linux-headers/linux/kvm.h | 45 ++++++++- target/s390x/cpu.c | 27 ++++-- target/s390x/cpu.h | 9 +- target/s390x/cpu_features_def.inc.h | 1 + target/s390x/diag.c | 61 ++++++++++-- target/s390x/gen-features.c | 1 + target/s390x/helper.c | 4 + target/s390x/ioinst.c | 113 +++++++++++++++------- target/s390x/kvm.c | 54 ++++++++++- target/s390x/kvm_s390x.h | 2 + target/s390x/mmu_helper.c | 14 +++ target/s390x/sigp.c | 1 + 23 files changed, 744 insertions(+), 65 deletions(-) create mode 100644 docs/system/protvirt.rst create mode 100644 hw/s390x/pv.c create mode 100644 hw/s390x/pv.h
