From: l00797255 <l00797255@huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I71UGQ CVE: NA Reference: N/A ---------------------------------------------------------------- MPAM interrupts are used to report error information and are non-functional interrupts. The current interrupt number is set to the default value 0. As a result, the device startup log contains the error indicating that the MPAM interrupt registration fails, which is sensitive. Therefore, the log level is changed to alarm.
