[btrfs] 8d47a0d8f7: fio.write_bw_MBps -28.6% regression

by kernel test robot

Greeting, FYI, we noticed a -28.6% regression of fio.write_bw_MBps due to commit: commit: 8d47a0d8f7947422dd359ac8e462687f81a7a137 ("btrfs: Do mandatory tree block check before submitting bio")

[tcp] 8b27dae5a2: netperf.Throughput_Mbps -25.7% regression

by kernel test robot

Greeting, FYI, we noticed a -25.7% regression of netperf.Throughput_Mbps due to commit: commit: 8b27dae5a2e89a61c46c6dbc76c040c0e6d0ed4c ("tcp: add one skb cache for rx") https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master in testcase: netperf on test machine: 104 threads Skylake with 192G memory with following parameters: ip: ipv4 runtime: 900s 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: +------------------+----------------------------------------------------+

CKI hackfest @Plumbers invite

by Veronika Kabatova

Hi, as some of you have heard, CKI Project is planning hackfest CI meetings after Plumbers conference this year (Sept. 12-13). We would like to invite everyone who has interest in CI for kernel to come and join us. The early agenda with summary is at the end of the email. If you think there's something important missing let us know! Also let us know in case you'd want to lead any of the sessions, we'd be happy to delegate out some work :) Please send us an email as soon as you decide to come and feel free to invite other people who should be present. We are not planning to cap the attendance right now but need to solve the logistics based on the interest. The event is free to attend, no additional registration except letting us know is needed. Feel free to contact us if you have any questions, Veronika CKI Project ----------------------------------------------------------- Here is an early agenda we put together: - Introductions - Common place for upstream results, result publishing in general - The discussion on the mailing list is going strong so we might be able to substitute this session for a different one in case everything is solved by September. - Test result interpretation and bug detection - How to autodetect infrastructure failures, regressions/new bugs and test bugs? How to handle continuous failures due to known bugs in both tests and kernel? What's your solution? Can people always trust the results they receive? - Getting results to developers/maintainers - Aimed at kernel developers and maintainers, share your feedback and expectations. - How much data should be sent in the initial communication vs. a click away in a dashboard? Do you want incremental emails with new results as they come in? - What about adding checks to tested patches in Patchwork when patch series are being tested? - Providing enough data/script to reproduce the failure. What if special HW is needed? - Onboarding new kernel trees to test - Aimed at kernel developers and maintainers. - Which trees are most prone to bring in new problems? Which are the most critical ones? Do you want them to be tested? Which tests do you feel are most beneficial for specific trees or in general? - Security when testing untrusted patches - How do we merge, compile, and test patches that have untrusted code in them and have not yet been reviewed? How do we avoid abuse of systems, information theft, or other damage? - Check out the original patch that sparked the discussion at https://patchwork.ozlabs.org/patch/862123/ - Avoiding effort duplication - Food for thought by GregKH - X different CI systems running ${TEST} on latest stable kernel on x86_64 might look useless on the first look but is it? AMD/Intel CPUs, different network cards, different graphic drivers, compilers, kernel configuration... How do we distribute the workload to avoid doing the same thing all over again while still running in enough different environments to get the most coverage? - Common hardware pools - Is this something people are interested in? Would be helpful especially for HW that's hard to access, eg. ppc64le or s390x systems. Companies could also sing up to share their HW for testing to ensure kernel works with their products.

Or rather it's a barrier(), which is anyway implied by rcu_read_lock(). So perhaps we can get rid of the IS_ENABLED() check?

[sched/fair] cca2ae2c00: aim7.jobs-per-min -35.9% regression

by kernel test robot

Greeting, FYI, we noticed a -35.9% regression of aim7.jobs-per-min due to commit: commit: cca2ae2c00b5fc7893f1a184d822812ee3425b7e ("sched/fair: Replace source_load() & target_load() w/ weighted_cpuload()") git://linux-arm.org/linux-de.git upstream/rem_rq_load in testcase: aim7 on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory with following parameters: disk: 1BRD_48G fs: xfs test: creat-clo load: 1500 cpufreq_governor: performance test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system. test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/ Details are as below:
