Subject: [PATCH v2 0/2] xen/x86: implement NMI continuation as softirq
Date: Wed, 7 Oct 2020 15:30:09 +0200 [thread overview]
Message-ID: <20201007133011.18871-1-jgross@suse.com> (raw)
Move sending of a virq event for oprofile to the local vcpu from NMI
to softirq context.
This has been tested with a small test patch using the continuation
framework of patch 1 for all NMIs and doing a print to console in
the continuation handler.
Version 1 of this small series was sent to the security list before.
