Subject: [RFC PATCH v6 78/92] kvm: x86: add tracepoints for interrupt and exception injections
Date: Fri,  9 Aug 2019 19:00:33 +0300
Message-ID: <20190809160047.8319-79-alazar@bitdefender.com> (raw)
In-Reply-To: <20190809160047.8319-1-alazar@bitdefender.com>

From: Nicușor Cîțu <ncitu@bitdefender.com>

This patch introduces additional tracepoints that are meant to help
in following the flow of interrupts and exceptions queued to a guest
VM. At the same time the kvm_exit tracepoint is enhanced with the
vCPU ID.

One scenario in which these help is debugging lost interrupts due to
a buggy VMEXIT handler.
