[PATCH 0/2] selftests: pmtu.sh: improve the test result processing

by Po-Hsu Lin

The pmtu.sh test script treats all non-zero return code as a failure, thus it will be marked as FAILED when some sub-test got skipped. This patchset will: 1. Use the kselftest framework skip code $ksft_skip to replace the hardcoded SKIP return code. 2. Improve the result processing, the test will be marked as PASSED if nothing goes wrong and not all the tests were skipped.

[PATCH 0/5] Add a dirty logging performance test

by Ben Gardon

Currently KVM lacks a simple, userspace agnostic, performance benchmark for dirty logging. Such a benchmark will be beneficial for ensuring that dirty logging performance does not regress, and to give a common baseline for validating performance improvements. The dirty log perf test introduced in this series builds on aspects of the existing demand paging perf test and provides time-based performance metrics for enabling and disabling dirty logging, getting the dirty log, and dirtying memory. While the test currently only has a build target for x86, I expect it will work on, or be easily modified to support other architectures. Ben Gardon (5): KVM: selftests: Factor code out of demand_paging_test KVM: selftests: Remove address rounding in guest code KVM: selftests: Simplify demand_paging_test with timespec_diff_now KVM: selftests: Add wrfract to common guest code KVM: selftests: Introduce the dirty log perf test tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 1 + .../selftests/kvm/demand_paging_test.c | 230 ++--------- .../selftests/kvm/dirty_log_perf_test.c | 382 ++++++++++++++++++ .../selftests/kvm/include/perf_test_util.h | 192 +++++++++ .../testing/selftests/kvm/include/test_util.h | 2 + tools/testing/selftests/kvm/lib/test_util.c | 22 +- 7 files changed, 635 insertions(+), 195 deletions(-) create mode 100644 tools/testing/selftests/kvm/dirty_log_perf_test.c create mode 100644 tools/testing/selftests/kvm/include/perf_test_util.h -- 2.29.0.rc2.309.g374f81d7ae-goog
