Subject: [drm/mgag200] 90f479ae51: vm-scalability.median -18.8% regression
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 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/
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
