[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 80G memory with following parameters: runtime: 300s size: 8T test: anon-cow-seq-hugetlb cpufreq_governor: performance test-description: The motivation behind this suite is to exercise functions and

[xfs] fdbb8c5b80: aim7.jobs-per-min 3.9% improvement

by kernel test robot

Greeting, FYI, we noticed a 3.9% improvement of aim7.jobs-per-min due to commit: commit: fdbb8c5b805c19bc2764aa1b91952e75e4c1c086 ("xfs: devirtualize ->data_entsize") https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master in testcase: aim7 on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory with following parameters: disk: 1BRD_48G fs: xfs test: disk_wrt load: 3000 cpufreq_governor: performance ucode: 0x2000065 test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to
