The timeout is set to 10 seconds because the test should complete in a fraction of a second even on busy machines. If the test is run in VSIE and the host of the host is not handling MVPG properly, the test will probably hang. Testing MVPG behaviour in VSIE is the main motivation for this test. Anything related to storage keys is not tested. v3->v4 * add memset after the first successful mvpg to make sure memory is really copied successfully * add a comment and an additional prefix to the tests skipped when running in TCG v2->v3 * fix copyright (2020 is over!) * add the third patch to skip some known issues when running in TCG v1->v2 * droppped patch 2 which introduced is_pgm(); * patch 1: replace a hardcoded value with the new macro SVC_LEAVE_PSTATE * patch 2: clear_pgm_int() returns the old value, use that instad of is_pgm() Claudio Imbrenda (3): s390x: introduce leave_pstate to leave userspace s390x: mvpg: simple test s390x: mvpg: skip some tests when using TCG s390x/Makefile | 1 + lib/s390x/asm/arch_def.h | 7 + lib/s390x/interrupt.c | 12 +- s390x/mvpg.c | 277 +++++++++++++++++++++++++++++++++++++++ s390x/unittests.cfg | 4 + 5 files changed, 299 insertions(+), 2 deletions(-) create mode 100644 s390x/mvpg.c
