2016-05-23xen: add pvUSB backendJuergen Gross
Add a backend for para-virtualized USB devices for xen domains. The backend is using host-libusb to forward USB requests from a domain via libusb to the real device(s) passed through.

2016-05-23xen: write information about supported backendsJuergen Gross
Add a Xenstore directory for each supported pv backend. This will allow Xen tools to decide which backend type to use in case there are multiple possibilities. The information is added under /local/domain/<backend-domid>/device-model/<domid>/backends before the "running" state is written to Xenstore. Using a directory for each backend enables us to add parameters for specific backends in the future. This interface is documented in the Xen source repository in the file docs/misc/qemu-backends.txt In order to reuse the Xenstore directory creation already present in hw/xen/xen_devconfig.c move the related functions to hw/xen/xen_backend.c where they fit better.

2016-05-23xen: introduce dummy system deviceJuergen Gross
Introduce a new dummy system device serving as parent for virtual buses. This will enable new pv backends to introduce virtual buses which are removable again opposed to system buses which are meant to stay once added.

2016-05-20machine: add properties to compat_props incrementalyIgor Mammedov
Switch to adding compat properties incrementaly instead of completly overwriting compat_props per machine type. That removes data duplication which we have due to nested [PC|SPAPR]_COMPAT_* macros. It also allows to set default device properties from default foo_machine_options() hook, which will be used in following patch for putting VMGENID device as a function if ISA bridge on pc/q35 machines.

2016-05-20vl: Replace DT_NOGRAPHIC with machine optionEduardo Habkost
All DisplayType values are just UI options that don't affect any hardware emulation code, except for DT_NOGRAPHIC. Replace DT_NOGRAPHIC with DT_NONE plus a new "-machine graphics=on|off" option, so hardware emulation code don't need to use the display_type variable.

2016-05-20aspeed: include qemu/log.hPaolo Bonzini
This is not visible with the default "log" trace backend. With other backends however trace.h does not include qemu/log.h, resulting in build failures.

2016-05-19hw: clean up hw/hw.h includesPaolo Bonzini
Include qom/object.h and exec/memory.h instead of exec/ioport.h; exec/ioport.h was almost everywhere required only for those two includes, not for the content of the header itself. Remove block/aio.h, everybody is already including it through another path. With this change, include/hw/hw.h is freed from qemu-common.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19hw: remove pio_addr_tPaolo Bonzini
pio_addr_t is almost unused, because these days I/O ports are simply accessed through the address space. cpu_{in,out}[bwl] themselves are almost unused; monitor.c and xen-hvm.c could use address_space_read/write directly, since they have an integer size at hand. This leaves qtest as the only user of those functions. On the other hand even portio_* functions use this type; the only interesting use of pio_addr_t thus is include/hw/sysbus.h. I guess I could move it there, but I don't see much benefit in that either. Using uint32_t is enough and avoids the need to include ioport.h everywhere. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19cpu: move exec-all.h inclusion out of cpu.hPaolo Bonzini
exec-all.h contains TCG-specific definitions. It is not needed outside TCG-specific files such as translate.c, exec.c or *helper.c. One generic function had snuck into include/exec/exec-all.h; move it to include/qom/cpu.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-05-19s390x: reorganize CSS bits between cpu.h and other headersPaolo Bonzini
Move cpu_inject_* to the only C file where they are used. Move ioinst.h declarations that need S390CPU to cpu.h, to make ioinst.h independent of cpu.h. Move channel declarations that only need SubchDev from cpu.h to css.h, to make more channel users independent of cpu.h.

2016-05-19dma: do not depend on kvm_enabled()Paolo Bonzini
Memory barriers are needed also by Xen and, when the ioeventfd bugs are fixed, by TCG as well. sysemu/kvm.h is not anymore needed in sysemu/dma.h, move it to the actual users. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19qemu-common: stop including qemu/host-utils.h from qemu-common.hPaolo Bonzini

2016-05-19hw: do not use VMSTATE_*TLPaolo Bonzini
