In-kernel ITS emulation on ARM64 will require to supply requester IDs. These IDs can now be retrieved from the device pointer using new pci_requester_id() function. This patch adds pci_dev pointer to KVM GSI routing functions and makes callers passing it. x86 architecture does not use requester IDs, but hw/i386/kvm/pci-assign.c also made passing PCI device pointer instead of NULL for consistency with the rest of the code.

2015-10-16util - add automated ID generation utilityJeff Cody1-0/+8
Multiple sub-systems in QEMU may find it useful to generate IDs for objects that a user may reference via QMP or HMP. This patch presents a standardized way to do it, so that automatic ID generation follows the same rules. This patch enforces the following rules when generating an ID: 1.) Guarantee no collisions with a user-specified ID 2.) Identify the sub-system the ID belongs to 3.) Guarantee of uniqueness 4.) Spoiling predictability, to avoid creating an assumption of object ordering and parsing (i.e., we don't want users to think they can guess the next ID based on prior behavior). The scheme for this is as follows (no spaces): # subsys D RR Reserved char --| | | | Subsystem String ----| | | Unique number (64-bit) --| | Two-digit random number ---| For example, a generated node-name for the block sub-system may look like this: #block076 The caller of id_generate() is responsible for freeing the generated node name string with g_free().

2015-10-16block: Add and use bdrv_replace_in_backing_chain()Kevin Wolf1-1/+3
This cleans up the mess we left behind in the mirror code after the previous patch. Instead of using bdrv_swap(), just change pointers. The interface change of the mirror job that callers must consider is that after job completion, their local BDS pointers still point to the same node now. qemu-img must change its code accordingly (which makes it easier to understand); the other callers stays unchanged because after completion they don't do anything with the BDS, but just with the job, and the job is still owned by the source BDS.

2015-10-16blockjob: Store device name at job creationKevin Wolf1-0/+8
Some block jobs change the block device graph on completion. This means that the device that owns the job and originally was addressed with its device name may no longer be what the corresponding BlockBackend points to. Previously, the effects of bdrv_swap() ensured that the job was (at least partially) transferred to the target image. Events that contain the device name could still use bdrv_get_device_name(job->bs) and get the same result. After removing bdrv_swap(), this won't work any more. Instead, save the device name at job creation and use that copy for QMP events and anything else identifying the job.

This is the final step in converting all of the BlockDriverState pointers that block drivers use to BdrvChild.

2015-10-12exec.c: Collect AddressSpace related fields into a CPUAddressSpace structPeter Maydell3-3/+7
Gather up all the fields currently in CPUState which deal with the CPU's AddressSpace into a separate CPUAddressSpace struct. This paves the way for allowing the CPU to know about more than one AddressSpace. The rearrangement also allows us to make the MemoryListener a directly embedded object in the CPUAddressSpace (it could not be embedded in CPUState because 'struct MemoryListener' isn't defined for the user-only builds). This allows us to resolve the FIXME in tcg_commit() by going directly from the MemoryListener to the CPUAddressSpace. This patch extracts the actual update of the cached dispatch pointer from cpu_reload_memory_map() (which is renamed accordingly to cpu_reloading_memory_map() as it is only responsible for breaking cpu-exec.c's RCU critical section now). This lets us keep the definition of the CPUAddressSpace struct private to exec.c.

2015-10-09qdev: Protect device-list-properties against broken devicesMarkus Armbruster1-0/+13
Several devices don't survive object_unref(object_new(T)): they crash or hang during cleanup, or they leave dangling pointers behind. This breaks at least device-list-properties, because qmp_device_list_properties() needs to create a device to find its properties. Broken in commit f4eb32b "qmp: show QOM properties in device-list-properties", v2.1. Example reproducer: $ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio {"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}} { "execute": "qmp_capabilities" } {"return": {}} { "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } } qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed. Aborted (core dumped) [Exit 134 (SIGABRT)] Unfortunately, I can't fix the problems in these devices right now. Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet to mark them: * Hang during cleanup (didn't debug, so I can't say why): "realview_pci", "versatile_pci". * Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic", "fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such CPUs * Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu", "host-powerpc64-cpu", "host-embedded-powerpc-cpu", "host-powerpc-cpu" (the powerpc ones can't currently reach the assertion, because the CPUs are only registered when KVM is enabled, but the assertion is arguably in the wrong place all the same) Make qmp_device_list_properties() fail cleanly when the device is so marked. This improves device-list-properties from "crashes, hangs or leaves dangling pointers behind" to "fails". Not a complete fix, just a better-than-nothing work-around. In the above reproducer, device-list-properties now fails with "Can't list properties of device 'pxa2xx-pcmcia'". This also protects -device FOO,help, which uses the same machinery since commit ef52358 "qdev-monitor: include QOM properties in -device FOO, help output", v2.2.

2015-10-09update-linux-headers: Rename SW_MAX to SW_MAX_Markus Armbruster1-2/+2
The next commit will compile hw/input/virtio-input.c and hw/input/virtio-input-hid.c even when CONFIG_LINUX is off. These files include both "include/standard-headers/linux/input.h" and <windows.h> then. Doesn't work, because both define SW_MAX. We don't actually use it. Patch input.h to define SW_MAX_ instead.
