From df3084ed5f95873e918d1ba96aef56735014588f Mon Sep 17 00:00:00 2001 From: David Gibson Date: Fri, 24 Jul 2015 05:26:18 +0200 Subject: [PATCH 56/58] spapr: Make hash table size a factor of maxram_size Message-id: <1437715580-14817-27-git-send-email-dgibson@redhat.com> Patchwork-id: 67143 O-Subject: [RHEL7.2 qemu-kvm-rhev PATCHv3 26/28] spapr: Make hash table size a factor of maxram_size Bugzilla: 1211117 RH-Acked-by: Laurent Vivier RH-Acked-by: Igor Mammedov RH-Acked-by: Laszlo Ersek The hash table size is dependent on ram_size, but since with hotplug the memory can grow till maxram_size. Hence make hash table size dependent on maxram_size. This allows to hotplug huge amounts of memory to the guest.
