[Test Case] Boot a KVM guest on PowerNV and measure the differences in memory consumption with and without this patch. [Fix] commit cec26bc3c125b5dd12a02f04133cd91eae3f1622 upstream in v3.18-rc1 -- Problem Description ================== This bugzilla is opened to track the inclusion of the upstream commit mentioned below: commit cec26bc3c125b5dd12a02f04133cd91eae3f1622 Author: Aneesh Kumar K.V <aneesh.ku...@linux.vnet.ibm.com> Date: Mon Sep 29 13:32:38 2014 +0530 KVM: PPC: BOOK3S: HV: CMA: Reserve cma region only in hypervisor mode We use cma reserved area for creating guest hash page table. Don't do the reservation in non-hypervisor mode. This avoids unnecessary CMA reservation when booting with limited memory configs like fadump and kdump. ---uname output--- ubuntu14.10 Machine Type = ppc64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1400209/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
