[tcp] ede61ca474: netperf.Throughput_Mbps 36.5% improvement
by kernel test robot
Greeting,
FYI, we noticed a 36.5% improvement of netperf.Throughput_Mbps due to commit:
commit: ede61ca474a0348b975d9824565b66c7595461de ("tcp: add tcp_rx_skb_cache sysctl")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: netperf
on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory
with following parameters:
ip: ipv4
runtime: 600s
nr_threads: 200%
cluster: cs-localhost
test: TCP_STREAM
cpufreq_governor: performance
test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/
In addition to that, the commit also has significant impact on the following tests:

[mm] 815744d751: will-it-scale.per_process_ops 43.3% improvement
by kernel test robot
Greeting,
FYI, we noticed a 43.3% improvement of will-it-scale.per_process_ops due to commit:
commit: 815744d75152078cde5391fc1e3c2d4424323fb6 ("mm: memcontrol: don't batch updates of local VM stats and events")
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) CPU @ 2.20GHz with 192G memory
with following parameters:
nr_task: 100%
mode: process
test: page_fault3
cpufreq_governor: performance
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:

[x86/hpet] 286b15db78: BUG:KASAN:wild-memory-access_in_t
by kernel test robot
FYI, we noticed the following commit (built with gcc-7):
commit: 286b15db78dc9741a47d082016dfc5fbcc31bd46 ("x86/hpet: Use channel for legacy clockevent storage")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git WIP.x86/hpet
in testcase: locktorture
with following parameters:
runtime: 300s
test: default
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 2G
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):

by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/hpet
commit dfd001e50c13ef71659eac2e04971ad23218fc6b
Author: Thomas Gleixner <tglx(a)linutronix.de>
AuthorDate: Mon Jun 17 16:47:17 2019 +0200

x86/hpet: Use common init for legacy clockevent
Replace the static initialization of the legacy clockevent with runtime
initialization utilizing the common init function as the last preparatory
step to switch the legacy clockevent over to the channel 0 storage in
hpet_base.
