[PATCH OLK-5.10] sdei_watchdog: Avoid exception during sdei handler
by Zheng Zengkai 23 Sep '23

23 Sep '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I82QPR -------------------------------- On Kunpeng920 platform, when firmware triggers SDEI event too soon, A WARN_ON() will be called in sdei_watchdog_callback(), this leads to warning "sdei: unsafe: exception during handler" being reported in _sdei_handler(). As the comments for the warning mentioned, We took a synchronous exception from the SDEI handler. This could deadlock, and if you interrupt KVM it will hyp-panic instead. Remove the WARN_ON() to avoid potential issue and warning.
