When handling failover, COLO processes differently according to the different stage of failover process, here we introduce a global atomic variable to record the status of failover. We add four failover status to indicate the different stage of failover process. You should use the helpers to get and set the value.

2016-10-30COLO: Add 'x-colo-lost-heartbeat' command to trigger failoverzhanghailiang12-1/+149
We leave users to choose whatever heartbeat solution they want, if the heartbeat is lost, or other errors they detect, they can use experimental command 'x_colo_lost_heartbeat' to tell COLO to do failover, COLO will do operations accordingly. For example, if the command is sent to the Primary side, the Primary side will exit COLO mode, does cleanup work, and then, PVM will take over the service work. If sent to the Secondary side, the Secondary side will run failover work, then takes over PVM's service work.

2016-10-30COLO: Load VMState into QIOChannelBuffer before restore itzhanghailiang1-2/+65
We should not destroy the state of SVM (Secondary VM) until we receive the complete data of PVM's state, in case the primary fails in the process of sending the state, so we cache the VM's state in secondary side before load it into SVM. Besides, we should call qemu_system_reset() before load VM state, which can ensure the data is intact.

2016-10-30COLO: Send PVM state to secondary side when do checkpointzhanghailiang2-17/+105
VM checkpointing is to synchronize the state of PVM to SVM, just like migration does, we re-use save helpers to achieve migrating PVM's state to Secondary side. COLO need to cache the data of VM's state in the secondary side before synchronize it to SVM. COLO need the size of the data to determine how much data should be read in the secondary side. So here, we can get the size of the data by saving it into I/O channel before send it to the secondary side.

2016-10-30COLO: Introduce checkpointing protocolzhanghailiang3-2/+226
We need communications protocol of user-defined to control the checkpointing process. The new checkpointing request is started by Primary VM, and the interactive process like below: Checkpoint synchronizing points: Primary Secondary initial work 'checkpoint-ready' <-------------------- @ 'checkpoint-request' @ --------------------> Suspend (Only in hybrid mode) 'checkpoint-reply' <-------------------- @ Suspend&Save state 'vmstate-send' @ --------------------> Send state Receive state 'vmstate-received' <-------------------- @ Release packets Load state 'vmstate-load' <-------------------- @ Resume Resume (Only in hybrid mode) Start Comparing (Only in hybrid mode) NOTE: 1) '@' who sends the message 2) Every sync-point is synchronized by two sides with only one handshake(single direction) for low-latency. If more strict synchronization is required, a opposite direction sync-point should be added. 3) Since sync-points are single direction, the remote side may go forward a lot when this side just receives the sync-point. 4) For now, we only support 'periodic' checkpoint, for which the Secondary VM is not running, later we will support 'hybrid' mode.

2016-10-28net: split colo_compare_pkt_info into two trace eventsAlex Bennée2-11/+13
It seems there is a limit to the number of arguments a UST trace event can take and at 11 the previous trace command broke the build. Split the trace into a src pkt and dst pkt trace to fix this.

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 ...

2016-10-28scripts/clean-includes: added duplicate #include checkAnand J1-14/+42
Enhance the clean-includes script to optionally check for duplicate #include entries. Script might output false positive entries as well. Such entries should not be removed. So if it finds any duplicate entries script will terminate with an exit status 1. Then each and every file should be checked manually and corrected if necessary. In order to enable the check use --check-dup-head option with scripts/clean-includes.

2016-10-28s390: avoid always-true comparison in s390_pci_generate_fid()Peter Maydell1-8/+2
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. Rephrase the loop to avoid the unnecessary duplicate-but-never-true conditional.
