2016-10-30COLO: migrate COLO related info to secondary nodezhanghailiang
We can determine whether or not VM in destination should go into COLO mode by referring to the info that was migrated. We skip this section if COLO is not enabled (i.e. migrate_set_capability colo off), so that, It doesn't break compatibility with migration no matter whether users configure the --enable-colo/disable-colo on the source/destination side or not; Signed-off-by: zhanghailiang <zhang.zhanghailiang@huawei.com> Signed-off-by: Li Zhijian <lizhijian@cn.fujitsu.com> Signed-off-by: Gonglei <arei.gonglei@huawei.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Amit Shah <amit@amitshah.net>
2016-10-30migration: Introduce capability 'x-colo' to migrationzhanghailiang
We add helper function colo_supported() to indicate whether colo is supported or not, with which we use to control whether or not showing 'x-colo' string to users, they can use qmp command 'query-migrate-capabilities' or hmp command 'info migrate_capabilities' to learn if colo is supported. The default value for COLO (COarse-Grain LOck Stepping) is disabled.

into staging ppc patch queue 2016-10-28 This pull request supersedes and extends the one from 2016-10-26 (which had a build bug). Highlights: * SLOF (pseries guest firmware) update * Enable a number of extra testcases on ppc / pseries * Added the 'powernv' machine type - Almost enough to be minimally usable - But still missing necessary interrupt controller updates * Cleanup and consolidation of NVRAM handling on several platforms with related firmware * Substantial cleanup to device tree construction * Some more POWER9 instruction emulation * Cleanup to handling of pseries option vectors and CAS reboot handling (host/guest feature negotiation mechanism) * Significant cleanups to handling of PCI devices in test cases * New hotplug event infrastructure * Memory hot unplug support for pseries * Several bug fixes The NVRAM cleanup affects some Sun sparc platforms as well as ppc ones, but have been tested by the sparc maintainer (Mark Cave-Ayland). The test additions also include substantial general changes to the test framework that aren't strictly ppc related. They don't seem to break tests on other platforms, they're for the benefit of enabling tests on ppc and there isn't a specific maintainer for them, so they're included in this tree. # gpg: Signature made Fri 28 Oct 2016 02:37:19 BST # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.8-20161028: (73 commits) ppc: allow certain HV interrupts to be delivered to guests spapr: Memory hot-unplug support spapr: use count+index for memory hotplug spapr: Add DRC count indexed hotplug identifier type spapr: add hotplug interrupt machine options spapr_events: add support for dedicated hotplug event source spapr: update spapr hotplug documentation target-ppc: Add xvcmpnesp, xvcmpnedp instructions target-ppc: add xscmp[eq,gt,ge,ne]dp instructions tests: Add pseries machine to the prom-env-test, too spapr_nvram: Pre-initialize the NVRAM to support the -prom-env parameter libqos: Change PCI accessors to take opaque BAR handle tests: Don't assume structure of PCI IO base in ahci-test tests: Use qpci_mem{read,write} in ivshmem-test libqos: Add 64-bit PCI IO accessors tests: Clean up IO handling in ide-test libqos: Implement mmio accessors in terms of mem{read,write} libqos: Add streaming accessors for PCI MMIO tests: Adjust tco-test to use qpci_legacy_iomap() libqos: Better handling of PCI legacy IO ...

Coverity points out that the comparison "fid <= ZPCI_MAX_FID" in s390_pci_generate_fid() is always true (because fid is 32 bits and ZPCI_MAX_FID is 0xffffffff). This isn't a bug because the real loop termination condition is expressed later via an "if (...) break;" inside the loop, but it is a bit odd.

The versatilepb physical address space layout only has a 256MB region for RAM before the devices. Without a guard on the amount of RAM requested by the user we would happily create a RAM area that overlapped with the devices, resulting in very confusing behaviour (typically a guest crash).

2016-10-28hw/arm/pxa2xx: Set value default values for CCCR and CKEN on PXA255Guenter Roeck

Use default values from datasheet instead.
