Sometimes a test needs to send a command to a console without waiting for a pattern as a result, or the command issued do not produce any kind of output, like, for example, a `mount` command. This introduces the `exec_command` function to the avocado_qemu, allowing the test to send a command to the console without the need to match a pattern produced as a result.

when execute the following test command: "guestperf-batch.py --dst-host localhost --transport unix ..." test aborts and error message as the following be throwed: "launching VM Failed: [Errno 98] Address already in use". The reason is that batch script use the same monitor socket in all test cases and do not remove the socket file.

2021-03-16mac_via: remove VIA1 timer optimisationsMark Cave-Ayland
The original implementation of the Macintosh VIA devices in commit 6dca62a000 "hw/m68k: add VIA support" used timer optimisations to reduce high CPU usage on the host when booting Linux. These optimisations worked by waiting until VIA1 port B was accessed before re-arming the timers. The MacOS toolbox ROM constantly writes to VIA1 port B which calls via1_one_second_update() and via1_sixty_hz_update() to calculate the new expiry time, causing the timers to constantly reset and never fire. The effect of this is that the Ticks (0x16a) global variable holding the number of 60Hz timer ticks since reset is never incremented by the interrupt causing time to stand still. Whilst the code was introduced as a performance optimisation, it is likely that the high CPU usage was actually caused by the incorrect 60Hz timer interval fixed in the previous patch. Remove the optimisation to keep everything simple and enable the MacOS toolbox ROM to start keeping time.

2021-03-16mac_via: don't re-inject ADB response when switching to IDLE stateMark Cave-Ayland
The current workaround for the Linux ADB state machine in kernels < 5.6 switching the VIA back to IDLE state between send and receive modes is to re-inject the first byte of the response in the IDLE state, and then force the state machine into generating an autopoll reply. In fact what is happening is much simpler: analysis of traces from a real Quadra suggest that the existing data is returned as the first autopoll response rather than generating an immediate response starting whilst still in IDLE state. Update the ADB receive code to work in the same way, which allows the re-injection code to be completely removed from adb_via_receive() and for adb_via_poll() to be simplified accordingly.

2021-03-16fuzz: move some DMA hooksAlexander Bulekov
For the sparse-mem device, we want the fuzzer to populate entire DMA reads from sparse-mem, rather than hooking into the individual MMIO memory_region_dispatch_read operations. Otherwise, the fuzzer will treat each sequential read separately (and populate it with a separate pattern). Work around this by rearranging some DMA hooks. Since the fuzzer has it's own logic to skip accidentally writing to MMIO regions, we can call the DMA cb, outside the flatview_translate loop.

Even though the fuzzer's instrumentation eventually finds valid addresses, this can take some-time, and slows-down fuzzing progress (especially, when multiple DMA buffers are involved).

For testing, it can be useful to simulate an enormous amount of memory (e.g. 2^64 RAM). This adds an MMIO device that acts as sparse memory. When something writes a nonzero value to a sparse-mem address, we allocate a block of memory. For now, since the only user of this device is the fuzzer, we do not track and free zeroed blocks. The device has a very low priority (so it can be mapped beneath actual RAM, and virtual device MMIO regions).

2021-03-16vfio/migrate: Move switch of dirty tracking into vfio_memory_listenerKeqian Zhu
For now the switch of vfio dirty page tracking is integrated into @vfio_save_handler. The reason is that some PCI vendor driver may start to track dirty base on _SAVING state of device, so if dirty tracking is started before setting device state, vfio will report full-dirty to QEMU. However, the dirty bmap of all ramblocks are fully set when setup ram saving, so it's not matter whether the device is in _SAVING state when start vfio dirty tracking. Moreover, this logic causes some problems [1]. The object of dirty tracking is guest memory, but the object of @vfio_save_handler is device state, which produces unnecessary coupling and conflicts: 1. Coupling: Their saving granule is different (perVM vs perDevice). vfio will enable dirty_page_tracking for each devices, actually once is enough. 2. Conflicts: The ram_save_setup() traverses all memory_listeners to execute their log_start() and log_sync() hooks to get the first round dirty bitmap, which is used by the bulk stage of ram saving. However, as vfio dirty tracking is not yet started, it can't get dirty bitmap from vfio. Then we give up the chance to handle vfio dirty page at bulk stage. Move the switch of vfio dirty_page_tracking into vfio_memory_listener can solve above problems. Besides, Do not require devices in SAVING state for vfio_sync_dirty_bitmap().

2021-03-16vfio: Support host translation granule sizeKunkun Jiang
The cpu_physical_memory_set_dirty_lebitmap() can quickly deal with the dirty pages of memory by bitmap-traveling, regardless of whether the bitmap is aligned correctly or not. cpu_physical_memory_set_dirty_lebitmap() supports pages in bitmap of host page size. So it'd better to set bitmap_pgsize to host page size to support more translation granule sizes. [aw: The Fixes commit below introduced code to restrict migration support to configurations where the target page size intersects the host dirty page support. For example, a 4K guest on a 4K host. Due to the above flexibility in bitmap handling, this restriction unnecessarily prevents mixed target/host pages size that could otherwise be supported.

2021-03-16vfio: Set the priority of the VFIO VM state change handler explicitlyShenming Lu
In the VFIO VM state change handler when stopping the VM, the _RUNNING bit in device_state is cleared which makes the VFIO device stop, including no longer generating interrupts. Then we can save the pending states of all interrupts in the GIC VM state change handler (on ARM). So we have to set the priority of the VFIO VM state change handler explicitly (like virtio devices) to ensure it is called before the GIC's in saving.

2021-03-16vfio: Move the saving of the config space to the right place in VFIO migrationShenming Lu
On ARM64 the VFIO SET_IRQS ioctl is dependent on the VM interrupt setup, if the restoring of the VFIO PCI device config space is before the VGIC, an error might occur in the kernel. So we move the saving of the config space to the non-iterable process, thus it will be called after the VGIC according to their priorities. As for the possible dependence of the device specific migration data on it's config space, we can let the vendor driver to include any config info it needs in its own data stream.

2021-03-16spapr_iommu: Fix vhost integration regressionEric Auger
Previous work on dev-iotlb message broke spapr_iommu/vhost integration as it did for SMMU and virtio-iommu. The spapr_iommu currently only sends IOMMU_NOTIFIER_UNMAP notifications. Since commit 958ec334bca3 ("vhost: Unbreak SMMU and virtio-iommu on dev-iotlb support"), VHOST first tries to register IOMMU_NOTIFIER_DEVIOTLB_UNMAP notifier and if it fails, falls back to legacy IOMMU_NOTIFIER_UNMAP. So spapr_iommu must fail on the IOMMU_NOTIFIER_DEVIOTLB_UNMAP registration.

2021-03-16vfio: Do not register any IOMMU_NOTIFIER_DEVIOTLB_UNMAP notifierEric Auger
In an attempt to fix smmu/virtio-iommu - vhost regression, commit 958ec334bca3 ("vhost: Unbreak SMMU and virtio-iommu on dev-iotlb support") broke virtio-iommu integration. This is due to the fact VFIO registers IOMMU_NOTIFIER_ALL notifiers, which includes IOMMU_NOTIFIER_DEVIOTLB_UNMAP and this latter now is rejected by the virtio-iommu. As a consequence, the registration fails. VHOST behaves like a device with an ATC cache. The VFIO device does not support this scheme yet. Let's register only legacy MAP and UNMAP notifiers.
