[sched/hotplug] 3b808c1a40: kernel_BUG_at_kernel/sched/core.c
by kernel test robot
Greeting,
FYI, we noticed the following commit (built with gcc-9):
commit: 3b808c1a4045cc0fa0ccb328e273449dee7c548f ("sched/hotplug: Consolidate task migration on CPU unplug")
https://git.kernel.org/cgit/linux/kernel/git/peterz/queue.git sched/migrate-disable
in testcase: locktorture
version:
with following parameters:
runtime: 300s
test: cpuhotplug
test-description: This torture test consists of creating a number of kernel threads which acquire the lock and hold it for specific amount of time, thus simulating different critical region behaviors.
test-url: https://www.kernel.org/doc/Documentation/locking/locktorture.txt
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 8G

[kprobes] d002b8bc6d: will-it-scale.per_process_ops 8.4% improvement
by kernel test robot
Greeting,
FYI, we noticed a 8.4% improvement of will-it-scale.per_process_ops due to commit:
commit: d002b8bc6dbc20e9043e279196cff8795dba05fe ("kprobes: Add symbols for kprobe insn pages")
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: 50%
mode: process
test: signal1
cpufreq_governor: performance
ucode: 0x5002f01
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
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
