[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 |

[sched/fair] 070f5e860e: reaim.jobs_per_min -10.5% regression

by kernel test robot

Greeting, FYI, we noticed a -10.5% regression of reaim.jobs_per_min due to commit: commit: 070f5e860ee2bf588c99ef7b4c202451faa48236 ("sched/fair: Take into account runnable_avg to classify group") https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master in testcase: reaim on test machine: 4 threads Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz with 4G memory with following parameters:

[drm/i915/gen9] 53b9bd37af: phoronix-test-suite.clpeak.KernelLatency.us 22.5% regression

by kernel test robot

Greeting, FYI, we noticed a 22.5% regression of phoronix-test-suite.clpeak.KernelLatency.us due to commit: commit: 53b9bd37af59d1def99b20707536105857eb9bd0 ("drm/i915/gen9: Clear residual context state on context switch") https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git linux-5.4.y in testcase: phoronix-test-suite on test machine: 4 threads Intel(R) Core(TM) i7-7567U CPU @ 3.50GHz with 32G memory with following parameters: test: clpeak-1.0.1 cpufreq_governor: performance ucode: 0xca test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added. test-url: http://www.phoronix-test-suite.com/ If you fix the issue, kindly add following

[y2038] 412c53a680: will-it-scale.per_process_ops 11.7% improvement

by kernel test robot

Greeting, FYI, we noticed a 11.7% improvement of will-it-scale.per_process_ops due to commit: commit: 412c53a680a97cb1ae2c0ab60230e193bee86387 ("y2038: remove unused time32 interfaces") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: will-it-scale on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory with following parameters: nr_task: 100% mode: process test: mmap2 cpufreq_governor: performance ucode: 0x2000065 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

[btrfs] 8d47a0d8f7: fio.write_bw_MBps -28.6% regression

by kernel test robot

Greeting, FYI, we noticed a -28.6% regression of fio.write_bw_MBps due to commit: commit: 8d47a0d8f7947422dd359ac8e462687f81a7a137 ("btrfs: Do mandatory tree block check before submitting bio")
