Subject: [driver core] f9aa460672: will-it-scale.per_process_ops 2.4%
improvement
Greeting,
FYI, we noticed a 2.4% improvement of will-it-scale.per_process_ops due to commit:
commit: f9aa460672c9c56896cdc12a521159e3e67000ba ("driver core: Refactor fw_devlink feature")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
nr_task: 16
mode: process
test: eventfd1
cpufreq_governor: performance
ucode: 0x5003003
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------------------+
