    perf mem: Trace physical address for Arm SPE events · 62e6eb8d
    Leo Yan authored
    Currently, Arm SPE events don't trace physical address, therefore, the
    field 'phys_addr' is always zero in synthesized memory samples.  This
    leads to perf c2c tool cannot locate the memory node for samples.
    
    This patch enables configuration 'pa_enable' for Arm SPE events, so the
    physical address packet can be traced, finally this can allow perf c2c
    tool to locate properly for memory node.
