Add support for ibm,lrdr-capacity since this is needed by the guest kernel to know about the possible hot-pluggable CPUs and Memory. With this, pseries kernels will start reporting correct maxcpus in /sys/devices/system/cpu/possible. Also define the minimum hotpluggable memory size as 256MB.

The sPAPRMachineState structure includes an entry_point field containing the initial PC value for starting the machine, even though this always has the value 0x100.

The ram_limit field was imported from sPAPREnvironment where it predates the machine's ram size being available generically from machine->ram_size. Worse, the existing code was inconsistent about where it got the ram size from. Sometimes it used spapr->ram_limit, sometimes the global 'ram_size' and sometimes a local 'ram_size' masking the global. This cleans up the code to consistently use machine->ram_size, eliminating spapr->ram_limit in the process.

The code for -machine pseries maintains a global sPAPREnvironment structure which keeps track of general state information about the guest platform. This predates the existence of the MachineState structure, but performs basically the same function. Now that we have the generic MachineState, fold sPAPREnvironment into sPAPRMachineState, the pseries specific subclass of MachineState. This is mostly a matter of search and replace, although a few places which relied on the global spapr variable are changed to find the structure via qdev_get_machine().

XICS needs to know the upper value for cpu_index as it is used to compute the number of servers: smp_cpus * kvmppc_smt_threads() / smp_threads When passing -smp cpus=1,threads=9 on a POWER8 host, we end up with: 1 * 8 / 9 = 0 ... which leads to an assertion in both emulated: Number of servers needs to be greater 0 Aborted (core dumped) ... and in-kernel XICS: xics_kvm_realize: Assertion `icp->nr_servers' failed. Aborted (core dumped) With this patch, we are sure that nr_servers > 0. Passing the same bogus -smp option then leads to: qemu-system-ppc64: Cannot support more than 8 threads on PPC with KVM ... which is a lot more explicit than the XICS errors.

Current PPC code relies on -mem-path being used in order for hugepage support to be detected. With the introduction of MemoryBackendFile we can now handle this via: -object memory-file-backend,mem-path=...,id=hugemem0 \ -numa node,id=mem0,memdev=hugemem0 Management tools like libvirt treat the 2 approaches as interchangeable in some cases, which can lead to user-visible regressions even for previously supported guest configurations. Fix these by also iterating through any configured memory backends that may be backed by hugepages. Since the old code assumed hugepages always backed the entirety of guest memory, play it safe an pick the minimum across the max pages sizes for all backends, even ones that aren't backed by hugepages.

Fix pba_offset initialization value for Chelsio T5 Virtual Function device. The T5 hardware has a bug in it where it reports a Pending Interrupt Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead of the 0x1000 that the hardware actually uses internally. As the hardware doesn't return the correct pba_offset value, add a quirk to instead return a hardcoded value of 0x1000 when a Chelsio T5 VF device is detected. This bug has been fixed in the Chelsio's next chip series T6 but there are no plans to respin the T5 ASIC for this bug. It is just documented in the T5 Errata and left it at that.

On systems with guest visible IOMMU, adding a new memory region onto PCI bus calls vfio_listener_region_add() for every DMA window. This installs a notifier for IOMMU memory regions. The notifier is supposed to be removed vfio_listener_region_del(), however in the case of mixed PHB (emulated + VFIO devices) when last VFIO device is unplugged and container gets destroyed, all existing DMA windows stay alive altogether with the notifiers which are on the linked list which head was in the destroyed container. This unregisters IOMMU memory region notifier when a container is destroyed.

Instead of handling the eventfds on user-side they are handled on kernel side using - the KVM irqfd framework, - the VFIO driver virqfd framework. the virtual IRQ completion is trapped at interrupt controller This removes the need for fast/slow path swap.

Currently the "host" page size alignment API is really aligning to both host and target page sizes. There is the qemu_real_page_size which can be used for the actual host page size but it's missing a mask and ALIGN macro as provided for qemu_page_size. Complete the API. This allows system level code that cares about the host page size to use a consistent alignment interface without having to un-needingly align to the target page size. This also reduces system level code dependency on the cpu specific TARGET_PAGE_SIZE.
