[sched/fair] 3c29e651e1: hackbench.throughput -15.2% regression

by kernel test robot

Greeting, FYI, we noticed a -15.2% regression of hackbench.throughput due to commit: commit: 3c29e651e16dd3b3179cfb2d055ee9538e37515c ("sched/fair: Fall back to sched-idle CPU if idle CPU isn't found") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: hackbench on test machine: 16 threads Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory with following parameters: nr_threads: 100% mode: threads ipc: pipe cpufreq_governor: performance ucode: 0xca test-description: Hackbench is both a benchmark and a stress test for the Linux kernel scheduler. test-url: https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/sc... In addition to that, the commit also has significant impact on the following tests: +------------------+-----------------------------------------------------------------------+ | testcase: change |

[fs] b6509f6a8c: will-it-scale.per_thread_ops -12.6% regression

by kernel test robot

Greeting, FYI, we noticed a -12.6% regression of will-it-scale.per_thread_ops due to commit: commit: b6509f6a8c4313c068c69785c001451415969e44 ("Revert "fs: Do not check if there is a fsnotify watcher on pseudo inodes"") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: will-it-scale on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory with following parameters: nr_task: 100% mode: thread test: eventfd1 cpufreq_governor: performance ucode: 0x5002f01 test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two. test-url: https://github.com/antonblanchard/will-it-scale In addition to that, the commit also has significant impact on the following tests: +------------------+---------------------------------------------------------------------------+ | testcase: change | will-it-scale:

[x86/copy_mc] a0ac629ebe: fio.read_iops -43.3% regression

by kernel test robot

Greeting, FYI, we noticed a -43.3% regression of fio.read_iops due to commit: commit: a0ac629ebe7b3d248cb93807782a00d9142fdb98 ("x86/copy_mc: Introduce copy_mc_generic()") url: https://github.com/0day-ci/linux/commits/Dan-Williams/Renovate-memcpy_mcs... in testcase: fio-basic on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 256G memory with following parameters: disk: 2pmem fs: xfs mount_option: dax runtime: 200s nr_task: 50% time_based: tb rw: read bs: 2M ioengine: libaio test_size: 200G cpufreq_governor: performance ucode: 0x5002f01 test-description: Fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user. test-url: https://github.com/axboe/fio In addition to that, the commit also has significant impact on the following tests: +------------------+----------------------------------------------------------------------+ | testcase: change | fio-basic:

Another data point > is that my tests passes with siw. Hi Jason, The patch below is sufficient to unbreak blktests. I think that the deadlock while unloading rdma_rxe happens because the RDMA core waits for all ib_dev references to be dropped before dealloc_driver is called. The rdma_rxe dealloc_driver implementation drops an ib_dev reference. The dealloc_driver callback was introduced by commit d0899892edd0 ("RDMA/device: Provide APIs from the core code to help unregistration"). Do you agree that this regression has been introduced by commits d0899892edd0 and c367074b6c37 ("RDMA/rxe: Use driver_unregister and new unregistration API")?
