Subject: [sched/numa] 6499b1b2dd:
phoronix-test-suite.aom-av1.0.frames_per_second -25.0% regression
Greeting,
FYI, we noticed a -25.0% regression of phoronix-test-suite.aom-av1.0.frames_per_second due to commit:
commit: 6499b1b2dd1b8d404a16b9fbbf1af6b9b3c1d83d ("sched/numa: Replace runnable_load_avg by load_avg")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: phoronix-test-suite
on test machine: 16 threads Intel(R) Xeon(R) CPU X5570 @ 2.93GHz with 48G memory
with following parameters:
test: aom-av1-1.2.0
cpufreq_governor: performance
ucode: 0x1d
test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added.
