Subject: [Xen-devel] [PATCH 0/3] xen: async_exception_* cleanup
Date: Mon, 17 Feb 2020 11:17:37 +0000 [thread overview]
Message-ID: <20200217111740.7298-1-andrew.cooper3@citrix.com> (raw)
This infrastructure is only compiled for x86, very x86 specific (so of no
interest to other architectures), and very broken.
Amongst other things, MCEs have a higher priority than NMIs, and there is no
such thing as masking an MCE. In order to address these bugs (which will
completely change the infrastructure), start by moving it all out of common
code.
Andrew Cooper (3):
x86/nmi: Corrections and improvements to do_nmi_stats()
xen: Move async_exception_* infrastructure into x86
xen/x86: Rename and simplify async_event_* infrastructure
