4cdc489eb9 i386/kvm: Prefault memory on page state change
A page state change is typically followed by an access of the page(s) and
results in another VMEXIT in order to map the page into the nested page
table. Depending on the size of page state change request, this can
generate a number of additional VMEXITs. For example, under SNP, when
Linux is utilizing lazy memory acceptance, memory is typically accepted in
4M chunks. A page state change request is submitted to mark the pages as
private, followed by validation of the memory. Since the guest_memfd
currently only supports 4K pages, each page validation will result in
VMEXIT to map the page, resulting in 1024 additional exits.

When performing a page state change, invoke KVM_PRE_FAULT_MEMORY for the
size of the page state change in order to pre-map the pages and avoid the
additional VMEXITs. This helps speed up boot times.

1ab3d93fd2 vfio/iommufd: Save vendor specific device info
Some device information returned by ioctl(IOMMU_GET_HW_INFO) are vendor
specific. Save them as raw data in a union supporting different vendors,
then vendor IOMMU can query the raw data with its fixed format for
capability directly.

Because IOMMU_GET_HW_INFO is only supported in linux, so declare those
capability related structures with CONFIG_LINUX.

98962d6298 vfio/iommufd: Add properties and handlers to TYPE_HOST_IOMMU_DEVICE_IOMMUFD
Enhance HostIOMMUDeviceIOMMUFD object with 3 new members, specific
to the iommufd BE + 2 new class functions.

IOMMUFD BE includes IOMMUFD handle, devid and hwpt_id. IOMMUFD handle
and devid are used to allocate/free ioas and hwpt. hwpt_id is used to
re-attach IOMMUFD backed device to its default VFIO sub-system created
hwpt, i.e., when vIOMMU is disabled by guest. These properties are
initialized in hiod::realize() after attachment.

2 new class functions are [at|de]tach_hwpt(). They are used to
attach/detach hwpt. VFIO and VDPA can have different implementions,
so implementation will be in sub-class instead of HostIOMMUDeviceIOMMUFD,
e.g., in HostIOMMUDeviceIOMMUFDVFIO.

Add two wrappers host_iommu_device_iommufd_[at|de]tach_hwpt to wrap the
two functions.

e3353d63e1 vfio: return mr from vfio_get_xlat_addr
Modify memory_get_xlat_addr and vfio_get_xlat_addr to return the memory
region that the translated address is found in.  This will be needed by
CPR in a subsequent patch to map blocks using IOMMU_IOAS_MAP_FILE.

Also return the xlat offset, so we can simplify the interface by removing
the out parameters that can be trivially derived from mr and xlat.

Lastly, rename the functions to  to memory_translate_iotlb() and
vfio_translate_iotlb().

bc85aae420 vhost-user: return failure if backend crash when live migration
Live migration should be terminated if the vhost-user backend crashes
before the migration completes.

Specifically, since the vhost device will be stopped when VM is stopped
before the end of the live migration, in current implementation if the
backend crashes, vhost-user device set_status() won't return failure,
live migration won't perceive the disconnection between QEMU and the
backend.

When the VM is migrated to the destination, the inflight IO will be
resubmitted, and if the IO was completed out of order before, it will
cause IO error.

To fix this issue:
1. Add the return value to set_status() for VirtioDeviceClass.
  a. For the vhost-user device, return failure when the backend crashes.
  b. For other virtio devices, always return 0.
2. Return failure if vhost_dev_stop() failed for vhost-user device.

If QEMU loses connection with the vhost-user backend, virtio set_status()
can return failure to the upper layer, migration_completion() can handle
the error, terminate the live migration, and restore the VM, so that
inflight IO can be completed normally.

e0f300b36d system/runstate: add VM state change cb with return value
This patch adds the new VM state change cb type `VMChangeStateHandlerWithRet`,
which has return value for `VMChangeStateEntry`.

Thus, we can register a new VM state change cb with return value for device.
Note that `VMChangeStateHandler` and `VMChangeStateHandlerWithRet` are mutually
exclusive and cannot be provided at the same time.

This patch is the pre patch for 'vhost-user: return failure if backend crashes
when live migration', which makes the live migration aware of the loss of
connection with the vhost-user backend and aborts the live migration.

Virtio device will use VMChangeStateHandlerWithRet.

a89c3c9b2c dma: use current AioContext for dma_blk_io()
In the past a single AioContext was used for block I/O and it was
fetched using blk_get_aio_context(). Nowadays the block layer supports
running I/O from any AioContext and multiple AioContexts at the same
time. Remove the dma_blk_io() AioContext argument and use the current
AioContext instead.

This makes calling the function easier and enables multiple IOThreads to
use dma_blk_io() concurrently for the same block device.

8fd2518ef2 hw: Centralize handling of -machine dumpdtb option
Currently we handle the 'dumpdtb' machine sub-option ad-hoc in every
board model that has an FDT.  It's up to the board code to make sure
it calls qemu_fdt_dumpdtb() in the right place.

This means we're inconsistent and often just ignore the user's
command line argument:
 * if the board doesn't have an FDT at all
 * if the board supports FDT, but there happens not to be one
   present (usually because of a missing -fdt option)

This isn't very helpful because it gives the user no clue why their
option was ignored.

However, in order to support the QMP/HMP dumpdtb commands we require
now that every FDT machine stores a pointer to the FDT in
MachineState::fdt.  This means we can handle -machine dumpdtb
centrally by calling the qmp_dumpdtb() function, unifying its
handling with the QMP/HMP commands.  All the board code calls to
qemu_fdt_dumpdtb() can then be removed.

For this commit we retain the existing behaviour that if there
is no FDT we silently ignore the -machine dumpdtb option.

13057e064a overcommit: introduce mem-lock=on-fault
Locking the memory without MCL_ONFAULT instantly prefaults any mmaped
anonymous memory with a write-fault, which introduces a lot of extra
overhead in terms of memory usage when all you want to do is to prevent
kcompactd from migrating and compacting QEMU pages. Add an option to
only lock pages lazily as they're faulted by the process by using
MCL_ONFAULT if asked.

31ef3c333d tests/qtest: rename qtest_send_prefix and roll-up into qtest_send
qtest_send_prefix never actually sent something over the chardev, all
it does is print the timestamp to the QTEST_LOG when enabled. So
rename the function, make it static, remove the unused CharDev and
simplify all the call sites by handling that directly with
qtest_send (and qtest_log_send).
