Userspace should *NEVER* rely on the content of debugfs, it will change with time, it is not a guaranteed ABI, it's purely for people to look at... for debugging. Unfortunately we don't expose ISEL support via features (maybe we should, this is reasonably easy to fix, except that we are running short on feature bits and adding a new set of bits isn't totally trivial). At this stage I would recommend using arch 2.06 as your key/trigger and either add a handful of known PVR values (mfpvr is emulated) for other CPUs you know support it (there shouldn't be that many), or just do the heuristic :-( Cheers, Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
