[linus:master] [mm] 96204e1531: will-it-scale.per_thread_ops -3.9% regression
From: kernel test robot
Date: Thu Feb 08 2024 - 02:37:16 EST
Hello,
kernel test robot noticed a -3.9% regression of will-it-scale.per_thread_ops on:
commit: 96204e15310c218fd9355bdcacd02fed1d18070e ("mm: thp_get_unmapped_area must honour topdown preference")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: will-it-scale
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 512G memory
parameters:
test: page_fault1
cpufreq_governor: performance
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
