  • a23f96ee4   perf tools: Use 64-bit shifts with (TSC) time conversion ... Browse Code »

    Commit b9511cd761fa ("perf/x86: Fix time_shift in perf_event_mmap_page")
    altered the time conversion algorithms documented in the perf_event.h
    header file, to use 64-bit shifts. That was done to make the code more
    future-proof (i.e. some time in the future a 32-bit shift could be
    allowed). Reflect those changes in perf tools.

  • 0b4378608   perf tools: Allow TSC conversion on any arch ... Browse Code »

    It is possible to record a perf.data file on one architecture and
    process it on another.

    Consequently, TSC conversion functions need to be moved out of the arch
    directory.
