    Subject[PATCH 7/8] perf script: support physical addresses in script
    Date
    From: Kan Liang <kan.liang@intel.com>

    perf script print out physical addresses by applying phys_addr.
    Only display physical address when virtual address is selected. The
    physical address will be printed out right after virtual address.
