From: Junhao He <hejunhao3@huawei.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC0GTV ---------------------------------------------------------------------- The supported event number range of each Uncore PMUs is provided by each driver in hisi_pmu::check_event and out of range events will be rejected. A later version with expanded event number range needs to register the PMU with updated hisi_pmu::check_event even if it's the only update, which means the expanded events cannot be used unless the driver's updated. However the unsupported events won't be counted by the hardware so we can relax the event number check to allow the use the expanded events.
