Subject: [PATCH v9 81/84] KVM: introspection: add KVMI_EVENT_SINGLESTEP
Date: Wed, 22 Jul 2020 00:09:19 +0300
Message-ID: <20200721210922.7646-82-alazar@bitdefender.com> (raw)
In-Reply-To: <20200721210922.7646-1-alazar@bitdefender.com>

From: Nicușor Cîțu <ncitu@bitdefender.com>

This event is sent after each instruction when the singlestep has been
enabled for a vCPU.
