Hello,
kernel test robot noticed a 16.8% improvement of stress-ng.min-nanosleep.ops_per_sec on:
commit: b40c927345a91e687eac4c3c5ca03a99643cd0c4 ("hrtimer: Use hrtimer_start_expires_user() for hrtimer sleepers")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git timers/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: min-nanosleep
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
