2017-06-13hw/intc/arm_gicv3_its: Implement state save/restoreEric Auger
We need to handle both registers and ITS tables. While register handling is standard, ITS table handling is more challenging since the kernel API is devised so that the tables are flushed into guest RAM and not in vmstate buffers. Flushing the ITS tables on device pre_save() is too late since the guest RAM is already saved at this point. Table flushing needs to happen when we are sure the vcpus are stopped and before the last dirty page saving. The right point is RUN_STATE_FINISH_MIGRATE but sometimes the VM gets stopped before migration launch so let's simply flush the tables each time the VM gets stopped. For regular ITS registers we just can use vmstate pre_save() and post_load() callbacks.

2017-06-13kvm-all: Pass an error object to kvm_device_accessEric Auger
In some circumstances, we don't want to abort if the kvm_device_access fails. This will be the case during ITS migration, in case the ITS table save/restore fails because the guest did not program the vITS correctly. So let's pass an error object to the function and return the ioctl value. New callers will be able to make a decision upon this returned value. Existing callers pass &error_abort which will cause the function to abort on failure.

This reverts commit fe6824d12642b005c69123ecf8631f9b13553f8b. Conflicts hw/ppc/spapr_drc.c, because get_index() has been renamed spapr_get_index(). This didn't fix the problem. Once the hotplug has been started some memory is allocated and some structures are allocated. We don't free it when we ignore the unplug, and we can't because they can be in use by the kernel.

The cpu_setup() handler is only implemented by xics_kvm, where it really does a typical "realize" job. Moreover, the realize() handler is called shortly after cpu_setup(), on the same path. This patch converts xics_kvm to implement realize() instead of cpu_setup().

2017-06-09xics: setup cpu at realize timeGreg Kurz
Until recently, spapr used to allocate ICPState objects for the lifetime of the machine. They would only be associated to vCPUs in xics_cpu_setup() when plugging a CPU core. Now that ICPState objects have the same lifecycle as vCPUs, it is possible to associate them during realization. This patch hence open-codes xics_cpu_setup() in icp_realize(). The vCPU is passed as a property. Note that vCPU now needs to be realized first for the IRQs to be allocated. It also needs to resetted before ICPState realization in order to synchronize with KVM. Since ICPState objects are freed when unrealized, xics_cpu_destroy() isn't needed anymore and can be safely dropped.

Replace that with a fixed spapr_drc_name() function which generates the name on the fly from other information. This means: * We get rid of a method with only one implementation, and only local callers * We don't have to carry the name string around for the lifetime of the DRC * We use information added to the class structure to generate the name in standard format, so we don't need an explicit switch on drc type any more We also eliminate the 'name' property; it's basically useless since the only information in it can easily be deduced from other things.

2017-06-08spapr: Clean up handling of DR-indicatorDavid Gibson
There are 3 types of "indicator" associated with hotplug in the PAPR spec the "allocation state", "isolation state" and "DR-indicator". The first two are intimately tied to the various state transitions associated with hotplug. The DR-indicator, however, is different and simpler. It's basically just a guest controlled variable which can be used by the guest to flag state or problems associated with a device. The idea is that the hypervisor can use it to present information back on management consoles (on some machines with PowerVM it may even control physical LEDs on the machine case associated with the relevant device). For that reason, there's only ever likely to be a single update implementation so the set_indicator_state method isn't useful. Replace it with a direct function call. While we're there, make some small associated cleanups: * PAPR doesn't use the term "indicator state", just "DR-indicator" and the allocation state and isolation state are also considered "indicators". Rename things to be less confusing * Fold set_indicator_state() and rtas_set_indicator_state() into a single rtas_set_dr_indicator() function.

DRC classes have an entity_sense method to determine (in a specific PAPR sense) the presence or absence of a device plugged into a DRC. However, we only have one implementation of the method, which explicitly tests for different DRC types. This changes it to instead have different method implementations for the two cases: "logical" and "physical" DRCs. While we're at it, the entity sense method always returns RTAS_OUT_SUCCESS, and the interesting value is returned via pass-by-reference.

2017-06-06s390x/css: fence off MIDACornelia Huck
MIDA (modified indirect data addressing) is an optional facility, and we (currently) don't support it. Let's post an operand exception if the guest tries to set it in the orb and a channel program check if it is set in a ccw, as specified in the Principles of Operation.

2017-06-06spapr: Eliminate spapr_drc_get_type_str()David Gibson
This function was used in generating the device tree. However, now that we have different QOM types for different DRC types we can easily store the information we need in the class structure and avoid this specialized lookup function.

2017-06-06spapr: Move configure-connector state into DRCDavid Gibson
Currently the sPAPRMachineState contains a list of sPAPRConfigureConnector structures which store intermediate state for the ibm,configure-connector RTAS call. This was an attempt to separate this state from the core of the DRC state. However the configure connector process is intimately tied to the DRC model, so there's really no point trying to have two levels of interface here. Moving the configure-connector state into its corresponding DRC allows removal of a number of helpers for maintaining the anciliary list.

2017-06-06spapr: Clean up spapr_dr_connector_by_*()David Gibson
* Change names to something less ludicrously verbose * Now that we have QOM subclasses for the different DRC types, use a QOM typename instead of a PAPR type value parameter The latter allows removal of the get_type_shift() helper.

2017-06-06spapr: Introduce DRC subclassesDavid Gibson
Currently we only have a single QOM type for all DRCs, but lots of places where we switch behaviour based on the DRC's PAPR defined type. This is a poor use of our existing type system. So, instead create QOM subclasses for each PAPR defined DRC type. We also introduce intermediate subclasses for physical and logical DRCs, a division which will be useful later on. Instead of being stored in the DRC object itself, the PAPR type is now stored in the class structure. There are still many places where we switch directly on the PAPR type value, but this at least provides the basis to start to remove those.

2017-06-06spapr: Make DRC get_index and get_type methods into plain functionsDavid Gibson
These two methods only have one implementation, and the spec they're implementing means any other implementation is unlikely, verging on impossible. So replace them with simple functions.
