Subject: [linus:master] [cpuidle] 85975daeaa: stress-ng.sem-sysv.ops_per_sec
15.2% regression
Hello,
we reported
"[linux-next:master] [cpuidle] 85975daeaa: filebench.sum_operations/s 67.2% improvement"
in
https://lore.kernel.org/all/202503102146.28d80a16-lkp@intel.com/
now we got more bisect results for this commit. FYI.
kernel test robot noticed a 15.2% regression of stress-ng.sem-sysv.ops_per_sec on:
commit: 85975daeaa4d6ec560bfcd354fc9c08ad7f38888 ("cpuidle: menu: Avoid discarding useful information")
