Currently it would consider blocks for which get_refcount fails used. However, it's unlikely that get_refcount would succeed for the next cluster, so it's not really helpful. Return an error instead. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

get_refcount might need to load a refcount block from disk, so errors may happen. Return the error code instead of assuming a refcount of 1 and change the callers to respect error return values. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This changes the vpc block driver (for VHD) to read/write multiple sectors at once instead of doing a request for each single sector. Before this, running qemu-iotests for VPC took ages, now it's actually quite reasonable to run it always (down from ~1 hour to 40 seconds for me). Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Hook up any cleanup work which needs to be done here. Advantages over using atexit(3): (1) You get passed in a pointer to the notifier. If you embed that into your state struct you can use container_of() to get get your state info. (2) You can unregister, say when un-plugging a device.

Setting the ID in pci_nic_init() is a blatant violation of the DeviceState abstraction. Which even carries a comment advising against this: /* This structure should not be accessed directly. We declare it here so that it can be embedded in individual device state structures. */ What's worse, it bypasses the code ensuring unique qdev IDs: "-device virtio-net-pci,id=foo -net nic,id=foo -net nic,name=foo" happily creates three qdevs with ID "foo". That's because qdev relies on qemu_opts_create() to ensure unique IDs, but -net nic uses a different QemuOptsList, which means id is in a different namespace. And its name is not checked for uniqueness at all. -net nic and pci_add are legacy. Use -device and device_add if you want a NIC with a qdev ID. This reverts what's still left of commit eb54b6dc "qdev: add id= support for pci nics." Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

When mistakenly configuring two devices in the same PCI slot, QEMU gives a not entirely obvious message about a 'devfn' being in use: $ qemu -device rtl8139 -device virtio-balloon-pci,bus=pci.0,addr=0x3 qemu-kvm: -device virtio-balloon-pci,bus=pci.0,addr=0x3: PCI: devfn 24 not available for virtio-balloon-pci, in use by rtl8139 The user does not configure 'devfn' numbers, they use slot+function. Thus the error messages should be reported back to the user with that same terminology rather than the internal QEMU terminology. This patch makes it report: $ qemu -device rtl8139 -device virtio-balloon-pci,bus=pci.0,addr=0x3 qemu: -device virtio-balloon-pci,bus=pci.0,addr=0x3.7: PCI: slot 3 function 0 not available for virtio-balloon-pci, in use by rtl8139 Signed-off-by: NDaniel P.

Pass the MultiReqBuffer structure down all the way to the I/O submission instead of takin it apart. Also mark num_writes unsigned as it can't go negative, and take the check for any pending I/O requests into the submission function. Last but not least rename do_multiwrite to virtio_submit_multiwrite to fit the general naming scheme and make clear what it does.

To hot-unplug guest and host part of a network device, you do: device_del NIC-ID netdev_del NETDEV-ID For PCI devices, device_del merely tells ACPI to unplug the device. The device goes away for real only after the guest processed the ACPI unplug event. You have to wait until then (e.g. by polling info pci) before you can unplug the netdev. Not good. Fix by removing the "in use" check from do_netdev_del(). Deleting a netdev while it's in use is safe; packets simply get routed to the bit bucket.

Currently HPET ACPI table is created regardless of whether qemu actually created hpet device. This may confuse some guests that don't check that hpet is functional before using it. Solve this by passing info about hpets in qemu to seabios via fw config interface. Additional benefit is that seabios no longer uses hard coded hpet configuration. Proposed interface supports up to 8 hpets. This is the number defined by hpet spec. Signed-off-by: NGleb Natapov <gleb@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This command was of minimal use before, now it is useless as the hpet become a qdev device and is thus easily discoverable. We should definitely not set query-hpet in QMP's stone, and there is also no good reason to keep it for the interactive monitor.

This implements the HPET capability of routing IRQs to the front-side bus, aka MSI support. This feature can be enabled via the qdev property "msi" and is off by default. Note that switching it on can cause guests (at least Linux) to use the HPET as timer instead of the LAPIC. KVM users should recall that only the latter is currently available as fast in-kernel model.

Allow the intercept the RTC IRQ for the HPET legacy mode. Then push routing to IRQ8 completely into the HPET. This allows to turn hpet_in_legacy_mode() into a private function. Furthermore, this stops the RTC from clearing IRQ8 even if the HPET is in control. This patch comes with a side effect: The RTC timers will no longer be stoppend when there is no IRQ consumer, possibly causing a minor performance degration. But as the guest may want to redirect the RTC to the SCI in that mode, it should normally disable unused IRQ source anyway.

Register the HPET as a sysbus device and create it that way. As it can route its IRQs to any ISA IRQ, we need to connect it to all 24 of them.
