Subject: [linus:master] [x86/mm/tlb] 7e33001b8b:
will-it-scale.per_thread_ops 20.7% improvement
Hello,
in this test, we don't have CONFIG_DEBUG_VM.
# CONFIG_DEBUG_VM is not set
below report is just FYI.
kernel test robot noticed a 20.7% improvement of will-it-scale.per_thread_ops on:
commit: 7e33001b8b9a78062679e0fdf5b0842a49063135 ("x86/mm/tlb: Put cpumask_test_cpu() check in switch_mm_irqs_off() under CONFIG_DEBUG_VM")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: will-it-scale
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 104 threads 2 sockets (Skylake) with 192G memory
parameters:
nr_task: 100%
mode: thread
test: context_switch1
cpufreq_governor: performance
Details are as below:
