AGL 12.1 cluster demo with 'fio' tool
-
Renesas H3
Block device write performance decreased dramatically (near 4 times worth).
Fetch and build AGL 12.1.0:
repo init -m lamprey_12.1.0.xml -b lamprey -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
repo sync -c -d
source meta-agl/scripts/aglsetup.sh -m h3ulcb agl-devel agl-demo agl-refhw-h3
bitbake agl-cluster-demo-platform
Add 'fio' tool and rebuild:
project meta-agl-demo/ diff --git a/recipes-platform/images/agl-cluster-demo-platform.bb b/recipes-platform/images/agl-cluster-demo-platform.bb index ac31ae3..9733e33 100644 --- a/recipes-platform/images/agl-cluster-demo-platform.bb +++ b/recipes-platform/images/agl-cluster-demo-platform.bb @@ -4,6 +4,10 @@ require agl-cluster-demo-platform.inc LICENSE = "MIT" +IMAGE_INSTALL += " \ + fio \ +" + IMAGE_FEATURES_append = "" # add packages for cluster demo platform (include demo apps) here
Test on both versions: 12.0.1 and 12.1.0 using a command:
fio --randrepeat=1 --direct=1 --gtod_reduce=1 --name=test --bs=4k --iodepth=64 --size=256M --rw=randwrite
