disk: 1SSD
media: ssd
test: MRPM
fstype: ext4
directio: bufferedio
cpufreq_governor: performance
ucode: 0xd000331
test-description: FxMark is a filesystem benchmark that test multicore scalability.
test-url: https://github.com/sslab-gatech/fxmark
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
