Hello,
this report is just FYI.
in the config for this test:
https://download.01.org/0day-ci/archive/20260529/202605291602.aff7d092-lkp@intel.com/config-7.1.0-rc2+
there is:
# CONFIG_PREEMPT_RT is not set
below is full report.
kernel test robot noticed a 50.7% regression of stress-ng.mutex.ops_per_sec on:
commit: dd29c017aed628076e915fe4cdfb5392fd4c5cab ("sched/rt: Have RT_PUSH_IPI be default off for non PREEMPT_RT")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git sched/core
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 192 threads 2 sockets Intel(R) Xeon(R) 6740E CPU @ 2.4GHz (Sierra Forest) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: mutex
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+-----------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.cyclic.ops_per_sec 24.5% regression |
| test parameters | cpufreq_governor=performance |
| | method=itimer |
| | nr_threads=100% |
| | test=cyclic |
| | testtime=60s |
+------------------+-----------------------------------------------------------+
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@intel.com>
| Closes: https://lore.kernel.org/oe-lkp/202605291602.aff7d092-lkp@intel.com
