Was the kernel trace events infrastructure designed with that in mind? I.e. cross analysis? I must be missing something here, still ENOCOFFEE :-\
Yes, the libparsevents library was design for this from day one. That's why trace-cmd data file can be run on an ARM and read on x86, or PPC, or whatever. I did all my development testing against 32bit, 64bit and big and little endian. This was the case from the beginning.
I need to look at the code, but how does it do this? Copy the relevant /sys/kernel/debug/events formats in the header and then instead of looking at /sys/... look at those?
Does it still copy /proc/kallsyms?
