New options, maxmem and slots, are added to the QEMU command line memory parameter to specify the total amount of memory available to the guest as well as the number of memory slots available. As part of this work, additional results are provided for the Read SCP Information SCLP, and new implentation is added for the Read Storage Element Information, Attach Storage Element, Assign Storage and Unassign Storage SCLPs, which enables the s390 guest to manipulate the standby memory pool. This patchset is based on work originally done by Jeng-Fang (Nick) Wang. This patchset has been built to apply on the s390-next tree at: git://github.com/borntraeger/qemu.git s390-next Changes for v2: * Removed the patch that introduced the standby-mem operand and instead included Igor Mammedov's patches that add the mem-opts 'maxmem' and 'slots', with a slight modification due to the removal of qemu_opts_create_nofail. * Patch 3 was inserted to add a new qom object that encapsulate variables used by s390 memory hotplug. Patches 4 and 5 adjusted to use this object. * Added additional code comments and other minor changes per Alexander Graf's comments Igor Mammedov (2): vl: convert -m to QemuOpts vl.c: extend -m option to support options for memory hotplug Matthew Rosato (3): sclp-s390: Add device to manage s390 memory hotplug virtio-ccw: Include standby memory when calculating storage increment sclp-s390: Add memory hotplug SCLPs hw/s390x/s390-virtio-ccw.c | 42 +++++-- hw/s390x/sclp.c | 276 ++++++++++++++++++++++++++++++++++++++++++-- include/hw/s390x/sclp.h | 19 +++ qemu-options.hx | 10 +- target-s390x/cpu.h | 18 +++ target-s390x/kvm.c | 5 + vl.c | 98 ++++++++++++++-- 7 files changed, 440 insertions(+), 28 deletions(-) -- 1.7.9.5
