Hi, I am testing some new armv6 drivers in head and I wanted to try using Dtrace for instrumentation. I would like to collect performance data from new sdhci/MMCCAM drivers on the BeagelBone Black and a new ahci/sata driver on IMX6.

So far the DTrace examples from Brendand Gregg have not compiled, some of the one liners I have found online cause kernel panics, and I have been unable to get the TeachBSD presentation to compile (I have contacted gnn). ugh.

Does anyone, anywhere in the world have a copy of the TeachBSD presentations pre-compiled? OR even better, can some one provide filesystem/kernel level examples that I could use to capture information about read and write speeds to various storage devices?

Thanks,

dinsdale
