[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")

[drm/mgag200] 90f479ae51: vm-scalability.median -18.8% regression

by kernel test robot

Greeting, FYI, we noticed a -18.8% regression of vm-scalability.median due to commit: commit: 90f479ae51afa45efab97afdde9b94b9660dd3e4 ("drm/mgag200: Replace struct mga_fbdev with generic framebuffer emulation") https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master in testcase: vm-scalability on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with

Re: [LKP] [SUNRPC] 0472e47660: fsmark.app_overhead 16.0% regression

I used the same hardware and the same test parameters to test the two commits: e791f8e938 ("SUNRPC: Convert xs_send_kvec() to use iov_iter_kvec()") 0472e47660 ("SUNRPC: Convert socket page send code to use iov_iter()") If it is caused by NUMA, why only commit 0472e47660 throughput is decreased? The filesystem we test is NFS, commit 0472e47660 is related with the network, could you help to check if have any other clues for the regression. Thanks. -- Zhengjun Xing

Some questions on 0-day

by Dmitry Vyukov

Hello 0-day devs, [Hope I figures correct email addresses] I have some questions regarding state of 0-day project to better understand state of upstream kernel testing. 1. What kernel configs does 0-day bot use? In particular I am interested in various runtime debugging features. Is there a list of all configs? I've found one in a recent "[bpf] 9fe4f05d33: kernel_selftests.bpf.test_verifier.fail" report, but it does not include CONFIG_KASAN, though I am sure 0-day uses KASAN. So is it a different config? Or the config was "minimized" to exclude KASAN since it was not relevant for the failure? I am interested in the following debug features: KASAN, LOCKDEP, KMEMLEAK, FAULT_INJECTION, DEBUG_OBJECTS, DEBUG_VM. Are these used? Any other notable debug features that are used? 2. What tests are being run? Is there a list somewhere? I know that 0-day now runs a pretty extensive set of tests. But is there any quantitative qualification? Are you done with onboarding more test suites? Or you want to onboard more? How would you estimate your progress on test onboarding? Is it 10%, 50% or 90%? 3. On a related note, do you know test code coverage? Are there reports available? 4. As far as I understand there is no automated reporting and a human is involved in sending of each report. Is it correct? What is the reason? You want to double-check? It's not automated? Something else? 5. Do you intercept all incoming upstream patches or you know that some are missing? If you don't intercept all, what are the main sources? I know some people send pull requests to Linus from their github trees and these may skip most of the common process. 6. Does it happen that 0-day fails to parse/apply a patch? I mean things like parsing problems when 0-day just can't make sense out of the email text, or when you can't figure out base tree/branch. 7. As far as I understand 0-day has some heuristics to figure out base git repo/branch. How frequently do they fail? How much tuning and maintenance does this require? 8. What are your major pain points? Or where time is going to? Major TODO items? 9. How many people are working on 0-day? Or taking into account the project started long time ago, more relevant question is probably: what is the estimation of engineer-years spent on 0-day? Are there any major areas where the human time goes? Thanks in advance

[locking/rwsem] 91d2a812df: will-it-scale.per_thread_ops 871.4% improvement

by kernel test robot

Greeting, FYI, we noticed a 871.4% improvement of will-it-scale.per_thread_ops due to commit: commit: 91d2a812dfb98b3b4dad661529c33bc38d303461 ("locking/rwsem: Make handoff writer optimistically spin on owner") https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master in testcase: will-it-scale on test machine: 104 threads Skylake with 192G memory with following parameters: nr_task: 100% mode: thread test: malloc1 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 In addition to that, the commit also has significant impact on the following tests: +------------------+----------------------------------------------------------------------+ | testcase: change | reaim: | | test machine | 48 threads
