LMBench usage
Select lmbench package in buildroot menuconfig, regenerate your rootfs and copy ROOTFS/usr/bin/lmbench dir to your NFS root export or to your MMC. lmbench need a NFS link or the MMC to work as it needs a lot of storage place. For example:
$ cp -r $HOME/armadeus/buildroot/build_arm_nofpu/root/usr/bin/lmbench /local/export/usr/bin/
On the target do:
# cd /mnt/host/usr/bin/lmbench/scripts
The first time, configure the tests
# OS=armv5tejl-linux-gnu ./config-run
When asked, use in order:
MULTIPLE COPIES [default 1] 1 Job placement selection: 1 MB [default ] 8 SUBSET (ALL|HARWARE|OS|DEVELOPMENT) [default all] HARDWARE then default value (except for result mailing, choose no) except Processor mhz [default 189 MHz, 5.2910 nanosec clock] 192 FSDIR [default /var/tmp] /mnt/host/ Mail results [default yes] no
Then launch the test
# OS=armv5tejl-linux-gnu ./results
Wait some time (1 hour ;-) ) Then parse the results file from your host (it requires Perl)
$ cd NFSROOT/usr/bin/lmbench/scripts/ $ ./getsummary ../results/armv5tejl-linux-gnu/armadeus.*
