Hello,
kernel test robot noticed a -4.4% regression of stress-ng.pagemove.page_remaps_per_sec on:
commit: 8be7258aad44b5e25977a98db136f677fa6f4370 ("mseal: add mseal syscall")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: pagemove
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.pkey.ops_per_sec -3.6% regression |
| test machine | 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory |
| test parameters | cpufreq_governor=performance |
| | nr_threads=100% |
| | test=pkey |
| | 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
