We neglected to update the the channel-program-address field of the scsw after completion of the start or the halt function: Fortunately, Linux didn't miss it so far. Let's update it for the cases where the cpa is expected to be valid; in some cases, the cpa is 'unpredictable', so we leave it untouched.

Implement kvm_arm_vcpu_init() as a simple call to arm_arm_vcpu_init() (which uses the KVM_ARM_VCPU_INIT vcpu ioctl to tell the kernel to re-initialize the vCPU), rather than via the complicated code which saves a copy of the register state on first init and then writes it back to the kernel. This is much simpler and brings the 32-bit KVM code into line with the 64-bit code.

Currently the Makefile of disas/libvixl appends -I$(SRC_PATH)/disas/libvixl to QEMU_CFLAGS. As a consequence C++ files that #include "utils.h", such as disas/libvixl/a64/instructions-a64.cc, are going to look for utils.h on all the other include paths first. When building QEMU as part of the Xen make system, another unrelated utils.h file is going to be chosen for inclusion, causing a build failure: In file included from disas/libvixl/a64/instructions-a64.cc:27:0: /qemu/disas/libvixl/a64/instructions-a64.h:88:64: error: 'rawbits_to_float' was not declared in this scope const float kFP32PositiveInfinity = rawbits_to_float(0x7f800000); Fix the problem by prepending (rather than appending) the libvixl include path to QEMU_CFLAGS.

POWER8E is architecturally equal to POWER8 and POWER7+ is equal to POWER7. Also no user space tool makes any difference for CPU node name in the device tree (such as PowerPC,POWER7@0 vs. PowerPC,POWER7+@0). So there is no point in emulating POWER7+ and POWER8E apart from POWER7 and POWER8. Also, the previos patch implemented multiple PVR mask support per CPU class so POWER7 class now covers both POWER7 and POWER7+ CPUs, same is valid for POWER8/8E. This removes POWER7+ and POWER8E classes. This replaces references to POWER7P/POWER8E families with POWER7/POWER8 families.

So far it was enough to have a base PVR value and mask per CPU family such as POWER7 or POWER8. However there CPUs which are completely architecturally compatible but have different PVRs such as POWER7/POWER7+ and POWER8/POWER8E. For these CPUs, top 16 bits are CPU family and low 16 bits are the version. The families have PVR base values different enough so defining a mask which would cover both (or potentially more) CPUs within the family is not possible. This adds a pvr_match() callback to PowerPCCPUClass. The default handler simply compares PVR defined in the class. This implements ppc_pvr_match_power7/ppc_pvr_match_power8 callbacks for POWER7/8 families. These check for POWER7/POWER7+ and POWER8/POWER8E. This changes ppc_cpu_compare_class_pvr_mask() not to check masks but use the pvr_match() callback. Since all server CPUs use the same mask, this defines one mask value - CPU_POWERPC_POWER_SERVER_MASK - which is used everywhere now. This removes other mask definitions. This removes pvr_mask from PowerPCCPUClass as it is not used anymore. This removes pvr initialization for POWER7/8 families as it is not used to find the class, the pvr_match() callback is used instead.

There's a non bugfix here: re-enabling the vhost-user test, though the patch just brings back functionality that I disabled earlier to fix mingw build failures.

Devices can use a mix of qdev and QOM properties. Currently only the qdev properties are displayed by device-list-properties. This patch extends the property enumeration algorithm to also display QOM properties (excluding the implicit "type", "realized", "hotpluggable", and "parent_bus" properties). When a qdev property exists, use the qdev type name to preserve backwards compatibility. QOM type names can be different for bool (qdev on/off) and str (used by qdev pointers).

Before commit 580b6b2a(dataplane: use the QEMU block layer for I/O), dataplane for virtio-blk submits block I/O as a batch. This commit 580b6b2a replaces the custom linux AIO implementation(including submit I/O as a batch) with QEMU block layer, but this commit causes ~40% throughput regression on virtio-blk performance, and removing submitting I/O as a batch is one of the causes. This patch applies the newly introduced bdrv_io_plug() and bdrv_io_unplug() interfaces to support submitting I/O at batch for Qemu block layer, and in my test, the change can improve throughput by ~30% with 'aio=native'.
