* block: Add commit_active_start()Fam Zheng2013-12-201-3/+19
| | | | | | | | | | | | | | | | | | commit_active_start is implemented in block/mirror.c, It will create a job with "commit" type and designated base in block-commit command. This will be used for committing active layer of device. Sync mode is removed from MirrorBlockJob because there's no proper type for commit. The used information is is_none_mode. The common part of mirror_start and commit_active_start is moved to mirror_start_job(). Fix the comment wording for commit_start.

* device_tree: qemu_fdt_setprop: Rename val_array argPeter Crosthwaite2013-12-201-1/+1
| | | | | | | | | | | Looking at the implementation, this doesn't really have a lot to do with arrays. Its just a pointer to a buffer and is passed through to the wrapped fn (qemu_fdt_setprop) unchanged. So rename to make it consistent with libfdt, which in the wrapped function just calls it "val".

* roms: Flush icache when writing roms to guest memoryAlexander Graf2013-12-201-0/+1
| | | | | | | | | | | | | | | | | | We use the rom infrastructure to write firmware and/or initial kernel blobs into guest address space. So we're basically emulating the cache off phase on very early system bootup. That phase is usually responsible for clearing the instruction cache for anything it writes into cachable memory, to ensure that after reboot we don't happen to execute stale bits from the instruction cache. So we need to invalidate the icache every time we write a rom into guest address space. We do not need to do this for every DMA since the guest expects it has to flush the icache manually in that case. This fixes random reboot issues on e5500 (booke ppc) for me.

The first takes a VirtIODevice, the second takes a VirtioBusState - device_plugged/device_unplug callbacks in the VirtioBusClass (here it's just the naming that is inconsistent) - virtio_bus_destroy_device is not called by anyone (and since it calls qdev_free, it would be called by the proxies---but then the callback is useless since the proxies can do whatever they want before calling virtio_bus_destroy_device) And there is a k->init but no k->exit, hence virtio_device_exit is overwritten by subclasses (except virtio-9p). This cleans it up by: - renaming the device_unplug callback to device_unplugged - renaming virtio_bus_plug_device to virtio_bus_device_plugged, matching the callback name - renaming virtio_bus_destroy_device to virtio_bus_device_unplugged, removing the qdev_free, making it take a VirtIODevice and calling it from virtio_device_exit - adding a k->exit callback virtio_device_exit is still overwritten, the next patches will fix that.

So making them diverge. On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23 can be assigned to hpet as guest chooses. So we introduce intcap property to do that. Consider the compat and piix/q35, we finally have the following value for intcap: For piix, hpet's intcap is hard coded as IRQ2. For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise IRQ2, IRQ8, and IRQ16~23 are allowed. Signed-off-by: Liu Ping Fan <pingfank@linux.vnet.ibm.com> Reviewed-by: Michael S.

This however is not necessary when using -qtest as a "probe" together with a normal TCG-, KVM- or Xen-based virtual machine. Hence, split out the call to configure_icount into a new function that is called only for "-machine accel=qtest"; and disable those commands when running with an accelerator other than qtest. This also fixes an assertion failure with "qemu-system-x86_64 -machine accel=qtest" but no -qtest option. This is a valid case, albeit somewhat weird; nothing will happen in the VM but you'll still be able to interact with the monitor or the GUI. Now that qtest_init is not limited to an int(void) function, change global variables that are not used outside qtest_init to arguments. And finally, cleanup useless parts of include/sysemu/qtest.h. The file is not used at all for user-only emulation, and qtest is not available on Win32 due to its usage of sigwait. Reported-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Now it is possible to directly export an internal snapshot, which can be used to probe the snapshot's contents without qemu-img convert. Signed-off-by: Wenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
| * | snapshot: distinguish id and name in load_tmpWenchao Xia2013-12-042-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since later this function will be used so improve it. The only caller of it now is qemu-img, and it is not impacted by introduce function bdrv_snapshot_load_tmp_by_id_or_name() that call bdrv_snapshot_load_tmp() twice to keep old search logic. bdrv_snapshot_load_tmp_by_id_or_name() return int to let caller know the errno, and errno will be used later. Also fix a typo in comments of bdrv_snapshot_delete(). Signed-off-by: Wenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
