So far I've only ran into positive side effects. No noticeable load, pass normal functional tests, and still able to hit all low power states. In that variant I just added a load_start() function in addition to the load function and converted all the in tree callers to use this as they all called load() then start() in order anyway. This left the API behavior the same but optimized all current users. Regards, Richard W. I did get my ETM adaptor board back so I have been able to verify directly. ETM is cool in that you can get (depending on filtering) almost a 60 second complete capture of instruction execution during some use case. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
