My stack of patches is starting to lean, so lets try to put some of them upstream... The first part is just additions to the UV guest test and a library that makes checking the installed UV calls easier. Additionally we now check for the proper UV share/unshare availability when allocating IO memory instead of only relying on stfle 158. The second part adds a UV host test with a large number UV of return code checks. v2: * Added rev-bys * Added stfle 158 check to uv_os_is_host/guest * Added asserts to uv_query_test_feature() * Prevent specifying bit nr outside of range * Prevent checking for features without having queried them * Added !feature bit check to uv guest/host invalid command test * Renamed uv_query_test_feature() to uv_query_test_call() Janosch Frank (6): s390x: uv-guest: Add invalid share location test s390x: Add more Ultravisor command structure definitions s390x: uv: Add UV lib s390x: Test for share/unshare call support before using them s390x: uv-guest: Test invalid commands s390x: Add UV host test lib/s390x/asm/uv.h | 152 ++++++++++++- lib/s390x/io.c | 2 + lib/s390x/malloc_io.c | 5 +- lib/s390x/uv.c | 45 ++++ lib/s390x/uv.h | 10 + s390x/Makefile | 2 + s390x/uv-guest.c | 60 +++++- s390x/uv-host.c | 480 ++++++++++++++++++++++++++++++++++++++++++ 8 files changed, 743 insertions(+), 13 deletions(-) create mode 100644 lib/s390x/uv.c create mode 100644 lib/s390x/uv.h create mode 100644 s390x/uv-host.c -- 2.30.2
