memory: remove IOMMU MR iommu_set_page_size_mask() callback

Everything is now in place to use the Host IOMMU Device callbacks
to retrieve the page size mask usable with a given assigned device.
This new method brings the advantage to pass the info much earlier
to the virtual IOMMU and before the IOMMU MR gets enabled. So let's
remove the call to memory_region_iommu_set_page_size_mask in
vfio common.c and remove the single implementation of the IOMMU MR
callback in the virtio-iommu.c

Retrieve the Host IOMMU Device page size mask when this latter is set.
This allows to get the information much sooner than when relying on
IOMMU MR set_page_size_mask() call, whcih happens when the IOMMU MR
gets enabled. We introduce check_page_size_mask() helper whose code
is inherited from current virtio_iommu_set_page_size_mask()
implementation. This callback will be removed in a subsequent patch.

vdpa-dev: Fix initialisation order to restore VDUSE compatibility

VDUSE requires that virtqueues are first enabled before the DRIVER_OK
status flag is set; with the current API of the kernel module, it is
impossible to enable the opposite order in our block export code because
userspace is not notified when a virtqueue is enabled.

This requirement also mathces the normal initialisation order as done by
the generic vhost code in QEMU. However, commit 6c482547 accidentally
changed the order for vdpa-dev and broke access to VDUSE devices with
this.

This changes vdpa-dev to use the normal order again and use the standard
vhost callback .vhost_set_vring_enable for this. VDUSE devices can be
used with vdpa-dev again after this fix.

vhost_net intentionally avoided enabling the vrings for vdpa and does
this manually later while it does enable them for other vhost backends.
Reflect this in the vhost_net code and return early for vdpa, so that
the behaviour doesn't change for this device.

vdpa: trace skipped memory sections

Sometimes, certain parts are not being skipped in
vhost_vdpa_listener_region_del, but they are skipped in
vhost_vdpa_listener_region_add, or vice versa. The vhost-vdpa code
expects all parts to maintain their properties, so we're adding a trace
to help with debugging when any part is skipped.

virtio: use defer_call() in virtio_irqfd_notify()

virtio-blk and virtio-scsi invoke virtio_irqfd_notify() to send Used
Buffer Notifications from an IOThread. This involves an eventfd
write(2) syscall. Calling this repeatedly when completing multiple I/O
requests in a row is wasteful.

Use the defer_call() API to batch together virtio_irqfd_notify() calls
made during thread pool (aio=threads), Linux AIO (aio=native), and
io_uring (aio=io_uring) completion processing.

Behavior is unchanged for emulated devices that do not use
defer_call_begin()/defer_call_end() since defer_call() immediately
invokes the callback when called outside a
defer_call_begin()/defer_call_end() region.

fio rw=randread bs=4k iodepth=64 numjobs=8 IOPS increases by ~9% with a
single IOThread and 8 vCPUs. iodepth=1 decreases by ~1% but this could
be noise. Detailed performance data and configuration specifics are
available here:
https://gitlab.com/stefanha/virt-playbooks/-/tree/blk_io_plug-irqfd

This duplicates the BH that virtio-blk uses for batching. The next
commit will remove it.

No functional change intended except for tracing, that now includes the

virtio-iommu: Fix 64kB host page size VFIO device assignment

When running on a 64kB page size host and protecting a VFIO device
with the virtio-iommu, qemu crashes with this kind of message:

qemu-k

virtio-iommu: Fix 64kB host page size VFIO device assignment

When running on a 64kB page size host and protecting a VFIO device
with the virtio-iommu, qemu crashes with this kind of message:

qemu-kvm: virtio-iommu page mask 0xfffffffffffff000 is incompatible
with mask 0x20010000
qemu: hardware error: vfio: DMA mapping failed, unable to continue

This is due to the fact the IOMMU MR corresponding to the VFIO device
is enabled very late on domain attach, after the machine init.
The device reports a minimal 64kB page size but it is too late to be
applied. virtio_iommu_set_page_size_mask() fails and this causes
vfio_listener_region_add() to end up with hw_error();

To work around this issue, we transiently enable the IOMMU MR on
machine init to collect the page size requirements and then restore
the bypass state.

# 77812aa7 04-Jul-2023 Laurent Vivier <lvivier@redhat.com>

vhost-vdpa: mute unaligned memory error report

With TPM CRM device, vhost-vdpa reports an error when it tries
to register a listener for a non aligned memory region:

qemu-system-x86_64: vhost_vdp

vhost-vdpa: mute unaligned memory error report

With TPM CRM device, vhost-vdpa reports an error when it tries
to register a listener for a non aligned memory region:

qemu-system-x86_64: vhost_vdpa_listener_region_add received unaligned region
qemu-system-x86_64: vhost_vdpa_listener_region_del received unaligned region

This error can be confusing for the user whereas we only need to skip
the region (as it's already done after the error_report())

Rather than introducing a special case for TPM CRB memory section
to not display the message in this case, simply replace the
error_report() by a trace function (with more information, like the
memory region name).
