Sean requested I remove your Reviewed-by tags due to changes in the last round. Main change was the interface for the RNG. David: I made the default seed 1 since 0 isn't a valid input for this pRNG. Split random number generator from use in dirty_log_perf_test.c and perf_test_utils.c Colton Lewis (4): KVM: selftests: implement random number generator for guest code KVM: selftests: create -r argument to specify random seed KVM: selftests: randomize which pages are written vs read KVM: selftests: randomize page access order .../selftests/kvm/access_tracking_perf_test.c | 2 +- .../selftests/kvm/dirty_log_perf_test.c | 57 ++++++++++++++----- .../selftests/kvm/include/perf_test_util.h | 8 ++- .../testing/selftests/kvm/include/test_util.h | 7 +++ .../selftests/kvm/lib/perf_test_util.c | 32 +++++++++-- tools/testing/selftests/kvm/lib/test_util.c | 17 ++++++ 6 files changed, 99 insertions(+), 24 deletions(-) -- 2.38.1.273.g43a17bfeac-goog
