Subject: [PATCH 14/34] x86/pt: add HVM check to XEN_DOMCTL_unbind_pt_irq
Date: Fri, 17 Aug 2018 16:12:32 +0100 [thread overview]
Message-ID: <8dbf18b054300318c8e74dac8c43fadb5895c16c.1534518694.git-series.wei.liu2@citrix.com> (raw)
In-Reply-To: <cover.f5351150954129956fcf53a7781206b6295df78d.1534518694.git-series.wei.liu2@citrix.com>
Its counterpart is HVM only. Add the check to help dead code
elimination to figure out the call to pt_irq_destroy_bind is not
needed when HVM is not enabled.
