[bpf, x86_64] 1022a5498f: stress-ng.opcode.ops_per_sec 73.7% improvement

by kernel test robot

Greeting, FYI, we noticed a 73.7% improvement of stress-ng.opcode.ops_per_sec due to commit: commit: 1022a5498f6f745c3b5fd3f050a5e11e7ca354f0 ("bpf, x86_64: Use bpf_jit_binary_pack_alloc") url: https://github.com/0day-ci/linux/commits/Mauricio-V-squez/bpftool-Remove-... in testcase: stress-ng on test machine: 48 threads 2 sockets Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz with 112G memory with following parameters: nr_threads: 100% testtime: 60s class: cpu test: opcode cpufreq_governor: performance ucode: 0x42e Details are as below:

[random] f73c522c4c: stress-ng.getrandom.ops_per_sec 8450.8% improvement

by kernel test robot

Greeting, FYI, we noticed a 8450.8% improvement of stress-ng.getrandom.ops_per_sec due to commit: commit: f73c522c4c2094d1c434083ae362bbd4a2ed7348 ("random: use simpler fast key erasure flow on per-cpu keys") url: https://github.com/0day-ci/linux/commits/Yusuf-Khan/pga-dfl-pci-Make-sure... in testcase: stress-ng on test machine: 48 threads 2 sockets Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz with 112G memory with following parameters: nr_threads: 100% testtime: 60s class: cpu test: getrandom cpufreq_governor: performance ucode: 0x42e Details are as below: --------------------------------------------------------------------------------------------------> To reproduce: git clone https://github.com/intel/lkp-tests.git cd lkp-tests sudo bin/lkp install

the test, # please remove ~/.lkp and /lkp dir to run from a clean state. =========================================================================================
