</div>Thanks for the patch. Disk throughput/utilization is still not showing<br>
up though. AFAIK mtd devices do not write anything to /proc/diskstats so<br>
support for that would need to be added to the kernel in order to have<br>
such statistics.</blockquote><div><br>Hi all!<br>Yes, the thing that I noticed was that /proc/diskstats has no value for the mtd devices<br>and thus bootchart cannot show anything at all. I asked mtd developers for instruction on<br>
how to implement that to try to do it myself but couldn't as my knowledge of linux kernel is <br>very limited and did not have enough time to learn. But I think that adding those stats could<br>be easily done by an experienced kernel developer.<br>
