Subject: [PATCH 0/4] x86/Hyper-V: Panic code path fixes
Date: Tue, 17 Mar 2020 06:25:19 -0700 [thread overview]
Message-ID: <20200317132523.1508-1-Tianyu.Lan@microsoft.com> (raw)
From: Tianyu Lan <Tianyu.Lan@microsoft.com>
This patchset fixes some issues in the Hyper-V panic code path.
Patch 1 resolves issue that panic system still responses network
packets.
Patch 2-3 resolves crash enlightenment issues.
Patch 4 is to set crash_kexec_post_notifiers to true for Hyper-V
VM in order to report crash data or kmsg to host before running
kdump kernel.
Tianyu Lan (4):
x86/Hyper-V: Unload vmbus channel in hv panic callback
x86/Hyper-V: Free hv_panic_page when fail to register kmsg dump
x86/Hyper-V: Trigger crash enlightenment only once during system
crash.
x86/Hyper-V: Report crash register data or ksmg before running crash
