v3->v4: --- * avoid backslash at line end in scripts wherever possible (thanks Claudio) * remove selfmade interrupt handlers and use kvm-unit-test default handers. This simplifies the code quite a bit. * fix cpu timer and clock comparator confusion v2->v3: --- * rename TIMING_S390_SHIFT_US->S390_CLOCK_SHIFT_US (thanks Claudio) * rename cpu_timer_set -> cpu_timer_set_ms (thanks Claudio) v1->v2: --- * fix spelling mistakes/long lines (thanks Thomas) * quoting improvments (thanks Thomas) * smaller timeout for tests (thanks Thomas and Janis) * move function and defines for cpu timer to time.h (thanks Janosch) * fence tests for non-QEMU/KVM (thanks Janosch) QEMU suports a guest state "guest-panicked" which indicates something in the guest went wrong, for example on s390x, when an external interrupt loop was triggered. Since the guest does not continue to run when it is in the guest-panicked state, it is currently impossible to write panicking tests in kvm-unit-tests. Support from the runtime is needed to check that the guest enters the guest-panicked state. This series adds the required support to the runtime together with two tests for s390x which cause guest panics. Nico Boehr (4): runtime: add support for panic tests s390x: add CPU timer related defines and functions s390x: add extint loop test s390x: add pgm spec interrupt loop test lib/s390x/asm/arch_def.h | 1 + lib/s390x/asm/time.h | 17 ++++++++++- s390x/Makefile | 2 ++ s390x/panic-loop-extint.c | 59 +++++++++++++++++++++++++++++++++++++++ s390x/panic-loop-pgm.c | 39 ++++++++++++++++++++++++++ s390x/run | 2 +- s390x/unittests.cfg | 12 ++++++++ scripts/arch-run.bash | 49 ++++++++++++++++++++++++++++++++ scripts/runtime.bash | 3 ++ 9 files changed, 182 insertions(+), 2 deletions(-) create mode 100644 s390x/panic-loop-extint.c create mode 100644 s390x/panic-loop-pgm.c -- 2.36.1
