    Subject[PATCH 5.14 139/849] perf/x86/intel/uncore: Fix Intel ICX IIO event constraints
    Date
    From: Kan Liang <kan.liang@linux.intel.com>

    commit f42e8a603c88f72bf047a710b9fc1d3579f31e71 upstream.

    According to the latest uncore document, both NUM_OUTSTANDING_REQ_OF_CPU
    (0x88) event and COMP_BUF_OCCUPANCY(0xd5) event also have constraints. Add
    them into the event constraints table.

    Fixes: 2b3b76b5ec67 ("perf/x86/intel/uncore: Add Ice Lake server uncore support")
