[PATCH OLK-6.6 1/2] drivers/perf: hisi: Clarifying event names and fix event ID for pa_pmu
From: Junhao He <hejunhao3@huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICFG22 ---------------------------------------------------------------------- The rx_req and tx_req events were only counting the number of flit package requests for link0. Hisilicon PA supports 4 links (0-3), and the original event names could be misinterpreted as counting the total flit packages across all links. Additionally, the tx_req event ID was incorrect. Fixes this by: 1) Adding the "link0" suffix and "pa" prefix to the event names to clearly indicate that they are specific to link0 and belong to the PA PMU. 2) Updating the tx_req event ID to 0x60 to reflect the correct identifier. These changes ensure accurate event naming and counting for link0 and flit packages.
