    Subject[PATCH 5.10 385/663] perf intel-pt: Fix missing CYC processing in PSB
    Date
    From: Adrian Hunter <adrian.hunter@intel.com>

    [ Upstream commit 03fb0f859b45d1eb05c984ab4bd3bef67e45ede2 ]

    Add missing CYC packet processing when walking through PSB+. This
    improves the accuracy of timestamps that follow PSB+, until the next
    MTC.

    Fixes: 3d49807870f08 ("perf tools: Add new Intel PT packet definitions")
