Hi Dmitry,

Yes, I know, the non-portability of perf.data is a big issue, and one of the design goals of spr-replay.

The generated program by spr-replay is perfectly portable, but due to the way perf data format is, they are not. We can't do anything about perf.data, but the spr-replay program should be trivially portable.

I'll switch on the mainline kernel tag and retry.

Regards

Oops. This should be investigated. We definitely wants the perf data to be portable (or, at least, portable with some limitations between different hardware of the same major architecture).

Could you give me an example of your perf.data?

Can you point to the pandaboard kernel that you use?

The kernel is 3.4.0-rc2+ (git 258f742635360175564e9470eb060ff4d4b984e7) cloned from Linus' tree.
