From 191941692a3d1b6a9614502b279be062926b70f5 Mon Sep 17 00:00:00 2001 From: zhenwei pi Date: Thu, 2 Jan 2020 10:35:13 +0800 Subject: misc: pvpanic: add crash loaded event Some users prefer kdump tools to generate guest kernel dumpfile, at the same time, need a out-of-band kernel panic event. Currently if booting guest kernel with 'crash_kexec_post_notifiers', QEMU will receive PVPANIC_PANICKED event and stop VM. If booting guest kernel without 'crash_kexec_post_notifiers', guest will not call notifier chain. Add PVPANIC_CRASH_LOADED bit for pvpanic event, it means that guest kernel actually hit a kernel panic, but the guest kernel wants to handle by itself.
