Subject: [PATCH v2 02/11] x86/xen: don't indicate DCA support in pv domains
Date: Thu, 13 Apr 2017 12:11:07 +0200 [thread overview]
Message-ID: <20170413101116.723-3-jgross@suse.com> (raw)
In-Reply-To: <20170413101116.723-1-jgross@suse.com>
Xen doesn't support DCA (direct cache access) for pv domains. Clear
the corresponding capability indicator.
