This is the absolute minimum needed to run VMs inside the KVM Unit Tests. It's more of a base for other tests that I can't (yet) publish than an addition of tests that check KVM functionality. However, I wanted to decrease the number of WIP patches in my private branch. Once the library is available maybe others will come and extend the SIE test itself. Yes, I have added VM management functionality like VM create/destroy, etc but as it is not needed right now, I'd like to exclude it from this patch set for now. v3: * Rebased on re-license patches * Split assembly * Now using ICPT_* constants * Added read_info asserts * Fixed missing spin_lock() in smp.c lib * Replaced duplicated code in sie test with generic intercept test * Replaced uv-guest.x bit testing with test_bit_inv() * Some other minor cleanups Gitlab: https://gitlab.com/frankja/kvm-unit-tests/-/tree/sie CI: https://gitlab.com/frankja/kvm-unit-tests/-/pipelines/228396011 Janosch Frank (8): s390x: Add test_bit to library s390x: Consolidate sclp read info s390x: SCLP feature checking s390x: Split assembly and move to s390x/asm/ s390x: sie: Add SIE to lib s390x: sie: Add first SIE test s390x: Add diag318 intercept test s390x: Fix sclp.h style issues lib/s390x/asm-offsets.c | 13 +++ lib/s390x/asm/arch_def.h | 7 ++ lib/s390x/asm/bitops.h | 26 +++++ lib/s390x/asm/facility.h | 3 +- lib/s390x/interrupt.c | 7 ++ lib/s390x/io.c | 2 + lib/s390x/sclp.c | 52 ++++++++-- lib/s390x/sclp.h | 178 ++++++++++++++++++--------------- lib/s390x/sie.h | 197 +++++++++++++++++++++++++++++++++++++ lib/s390x/smp.c | 27 +++-- s390x/Makefile | 9 +- s390x/{ => asm}/cstart64.S | 119 +--------------------- s390x/asm/lib.S | 121 +++++++++++++++++++++++ s390x/asm/macros.S | 77 +++++++++++++++ s390x/intercept.c | 19 ++++ s390x/sie.c | 113 +++++++++++++++++++++ s390x/unittests.cfg | 3 + s390x/uv-guest.c | 6 +- 18 files changed, 754 insertions(+), 225 deletions(-) create mode 100644 lib/s390x/sie.h rename s390x/{ => asm}/cstart64.S (50%) create mode 100644 s390x/asm/lib.S create mode 100644 s390x/asm/macros.S create mode 100644 s390x/sie.c -- 2.25.1
