Hi Vince, So just have user/kernel selection for aarch64 platforms and punt on 32-bit arm even if it running on aarch64 processor with a pmu that could support user/kernel selection? -Will ------------------------------------------------------------------------------ _______________________________________________ perfmon2-devel mailing list perfmon2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/perfmon2-devel
