    SubjectRe: [PATCH v4 0/6] perf arm-spe: Enable timestamp
    From
    Date
    Hi Leo,

    I was looking at testing this on N1SDP and I thought I would try the round trip with perf inject and
    then perf report but saw that perf inject with SPE always results in an error (unrelated to your change)

    -> ./perf report -i per-thread-spe-time.inject.data
    0x1328 [0x8]: failed to process type: 9 [Bad address]
    Error:
    failed to process sample


    Do you have any test suggestions other than looking at the raw data?

    Thanks
    James
