[ Test Plan ] * Clone libtracefs (oracular-devel or noble-devel), compile it and make the tests (make && make test). * Then run the tests as root (utest/trace-utest), on an s390x machine (running oracular or noble) * You can test the fix by installing the patched version of libtraceevent for the release you are testing and trying the libtracefs tests again. [ Where problems could occur ] * This is not likely to break anything, as we can make a safe assumption to set file_bigendian to the same value as host_bigendian by default. If these are different, the user can set it using event-parse-api * In any case, this change seems logical. This does not affect any other (little-endian) architecture, and I think this won't be breaking any workarounds people did around this problem. * But in case we have some regressions as a result of this change, then there surely would be some workaround to this in a patch, which can then be reverted. [ Other Info ] * This does not fix anything in libtraceevent but does fix the tests for libtracefs on s390x. But I have opened this bug against libtraceevent. * I see a workaround for this problem in the last patch in d/p/series, but this change does not affect it __________ As part of the added QA to libtracefs it was found that it triggers a segfault on s390x. This isn't just a test failing, it seems this is still deeply broken on s390x. Either way, while in the time pressure of the noble release the decision was simplified like "The tests didn't make it worse, just now we know" and continued (To not leave these platforms behind later unable to add it, albeit knowing it is still incomplete for now). It does not mean that we can ignore them for too long and certainly need to work on completing that into being fully functional in tests and real usage. Hence we create this spin off bug from the MIR work in bug 2051925 for tracking the further efforts.
