[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

[cpuidle] 259231a045: will-it-scale.per_process_ops -12.6% regression

by kernel test robot

Greeting, FYI, we noticed a -12.6% regression of will-it-scale.per_process_ops due to commit: commit: 259231a045616c4101d023a8f4dcc8379af265a6 ("cpuidle: add poll_limit_ns to cpuidle_device structure") https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master in testcase: will-it-scale on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory with following parameters: nr_task: 100% mode: process test: mmap1 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 If you fix the issue, kindly add following tag Reported-by: kernel test robot <rong.a.chen(a)intel.com> Details are as below: --------------------------------------------------------------------------------------------------> To reproduce: git

[mm/lruvec] 3145e78472: vm-scalability.median -18.4% regression

by kernel test robot

Greeting, FYI, we noticed a -18.4% regression of vm-scalability.median due to commit: commit: 3145e78472f7ad746e15180092a9a60e34e5455b ("mm/lruvec: add irqsave flags into lruvec struct") https://github.com/alexshi/linux.git lru_lock in testcase: vm-scalability on test machine: 104 threads Skylake with 192G memory with following parameters: runtime: 300s test: lru-file-readtwice cpufreq_governor: performance test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us. test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/ In addition to that, the commit also has significant impact on the following tests:

d4f4de5e5e: aim9.dir_rtns_1.ops_per_sec -26.1% regression

by kernel test robot

Greeting, FYI, we noticed a -26.1% regression of aim9.dir_rtns_1.ops_per_sec due to commit: commit: d4f4de5e5ef8efde85febb6876cd3c8ab1631999 ("Fix the locking in dcache_readdir() and friends") https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master in testcase: aim9 on test machine: 4 threads Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz with 4G memory with following parameters:
