Hi all,
Is 'bootchart' a good tool to find the boot time
measurement from user space ? Could some one help me in using the same?
Is there any doc which supports how to incorporate bootchart in to Yocto
daisy build system and add the same in kernel boot command?
Regards,
Daniel C A

I have never used bootchart before. However, maybe a good starting point:
http://layers.openembedded.org/layerindex/branch/master/recipes/?q=bootchart
And this is something I'm interested. Would you mind to share your progress?

IIRC the kernel change needed is the boot timing printing. Aside it,
everything is userspace related.
