Re: [Xen-devel] adding traces in xentrace and xenalyze?

[Sisu Xi <xisisu@xxxxxxxxx>]

Hi, George:

oh, I did not modify xenalyze. I do notice that xenalyze has an option to dump all, but seems it will skip the user added traces. I'll look into the code to understand it.

Thanks.

Are you saying that you added code to xenalyze to pretty-print the
record, but still didn't see anything? ÂOr that you haven't tried to
add trace records to xenalyze yet?
