From mboxrd@z Thu Jan 1 00:00:00 1970 From: Konrad Rzeszutek Wilk Subject: [PATCH 5/6] xl: export 'outstanding_pages' value from xcinfo Date: Wed, 10 Apr 2013 15:59:57 -0400 Message-ID: <1365623998-13710-6-git-send-email-konrad.wilk@oracle.com> References: <1365623998-13710-1-git-send-email-konrad.wilk@oracle.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1365623998-13710-1-git-send-email-konrad.wilk@oracle.com> List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xen.org Errors-To: xen-devel-bounces@lists.xen.org To: xen-devel@lists.xensource.com, ian.campbell@citrix.com, ian.jackson@eu.citrix.com Cc: George.Dunlap@eu.citrix.com, dan.magenheimer@oracle.com, Konrad Rzeszutek Wilk List-Id: xen-devel@lists.xenproject.org This patch provides the value of the currently outstanding pages claimed for a specific domain. This is a value that influences the global outstanding claims value (See patch: "xl: 'xl info' print outstanding claims if enabled") returned via xc_domain_get_outstanding_pages hypercall. This domain value decrements as the memory is populated for the guest and eventually reaches zero. With this patch it is possible to utilize this field.
