block migration.
Also, ignore set and clear of VHOST_F_LOG_ALL on set_features if SVQ is

This tree is able to look for a translated address from an IOVA address.
At first glance it is similar to util/iova-tree. However, SVQ working on
devices with limited IOVA space need more capabilities, like allocating
IOVA chunks or performing reverse translations (qemu addresses to iova).
The allocation capability, as "assign a free IOVA address to this chunk
of memory in qemu's address space" allows shadow virtqueue to create a
new address space that is not restricted by guest's addressable one, so
we can allocate shadow vqs vrings outside of it.
It duplicates the tree so it can search efficiently in both directions,
and it will signal overlap if iova or the translated address is present
in any tree.

Initial version of shadow virtqueue that actually forward buffers. There
is no iommu support at the moment, and that will be addressed in future
patches of this series. Since all vhost-vdpa devices use forced IOMMU,
this means that SVQ is not usable at this point of the series on any
device.
For simplicity it only supports modern devices, that expects vring
in little endian, with split ring and no event idx or indirect
descriptors. Support for them will not be added in this series.
It reuses the VirtQueue code for the device part. The driver part is
based on Linux's virtio_ring driver, but with stripped functionality
and optimizations so it's easier to review.
However, forwarding buffers have some particular pieces: One of the most
unexpected ones is that a guest's buffer can expand through more than
one descriptor in SVQ. While this is handled gracefully by qemu's
emulated virtio devices, it may cause unexpected SVQ queue full. This
patch also solves it by checking for this condition at both guest's
kicks and device's calls. The code may be more elegant in the future if
SVQ code runs in its own iocontext.

It reports the shadow virtqueue address from qemu virtual address space.
Since this will be different from the guest's vaddr, but the device can
access it, SVQ takes special care about its alignment & lack of garbage
data. It assumes that IOMMU will work in host_page_size ranges for that.

This allows SVQ to negotiate features with the guest and the device. For
the device, SVQ is a driver. While this function bypasses all
non-transport features, it needs to disable the features that SVQ does
not support when forwarding buffers. This includes packed vq layout,
indirect descriptors or event idx.
Future changes can add support to offer more features to the guest,
since the use of VirtQueue gives this for free. This is left out at the
moment for simplicity.

Vhost shadow virtqueue (SVQ) is an intermediate jump for virtqueue
notifications and buffers, allowing qemu to track them. While qemu is
forwarding the buffers and virtqueue changes, it is able to commit the
memory it's being dirtied, the same way regular qemu's VirtIO devices
do.
This commit only exposes basic SVQ allocation and free. Next patches of
the series add functionality like notifications and buffers forwarding.

tries to fix the use after free of the sg by caching the virtqueue
elements in an array and unmap them at once after receiving the
packets, But it forgot to unmap the cached elements on error which
will lead to leaking of mapping and other unexpected results.
Fixing this by detaching the cached elements on error. This addresses
CVE-2022-26353.

On a real system with POWER{8,9,10} processors, PHBs are sub-units of
the processor, they can be deactivated by firmware but not plugged in
or out like a PCI adapter on a slot. Nevertheless, having user-created
PHBs in QEMU seemed to be a good idea for testing purposes :
1. having a limited set of PHBs speedups boot time.
2. it is useful to be able to mimic a partially broken topology you
some time have to deal with during bring-up.
PowerNV is also used for distro install tests and having libvirt
support eases these tasks. libvirt prefers to run the machine with
-nodefaults to be sure not to drag unexpected devices which would need
to be defined in the domain file without being specified on the QEMU
command line. For this reason :
3. -nodefaults should not include default PHBs
User-created PHB{3,4,5} devices satisfied all these needs but reality
proves to be a bit more complex, internally when modeling such
devices, and externally when dealing with the user interface.
Req 1. and 2. can be simply addressed differently with a machine option:
"phb-mask=<uint>", which QEMU would use to enable/disable PHB device
nodes when creating the device tree.
For Req 3., we need to make sure we are taking the right approach. It
seems that we should expose a new type of user-created PHB device, a
generic virtualized one, that libvirt would use and not one depending
on the processor revision. This needs more thinking.
For now, remove user-created PHB{3,4,5} devices. All the cleanups we
did are not lost and they will be useful for the next steps.

We already have the pnv-phb3 and pnv-phb4 devices for POWER8 and
POWER9 respectively. POWER10 uses version 5 of the PHB. It is very
close to the PHB4 from POWER9, at least in our model and we could
almost keep using the PHB4 model. However the matching root port
pnv-phb5-root-port is specific to POWER10 so to avoid confusion as
well as making it easy to introduce differences later, we create a
pnv-phb5 class, which is mostly an alias for pnv-phb4 for now.
With this patch, the command line for a user-created PHB on powernv10
becomes:
-machine powernv10 -nodefaults -device pnv-phb5 -device pnv-phb5-root-port

Since PDMA reads/writes are driven by the guest, it is possible that migration
can occur whilst a SCSIRequest is still active. Fortunately active SCSIRequests
are already included in the migration stream and restarted post migration but
this still leaves the reference in ESPState uninitialised.
Implement the SCSIBusInfo .load_request callback to obtain a reference to the
currently active SCSIRequest and use it to recreate ESPState current_req
after migration.

The mos6522 datasheet describes how the control lines IRQs are edge-triggered
according to the configuration in the PCR register. Implement the logic according
to the datasheet so that the interrupt bits in IFR are latched when the edge is
detected, and cleared when reading portA/portB or writing to IFR as necessary.
To maintain bisectibility this change also updates the SCSI, SCSI data, Nubus

The VIA2 on the Q800 machine is not a separate chip as in older Macs but instead
is integrated into the on-board logic. From analysing the SCSI routines in the
MacOS toolbox ROM (and to a lesser extent NetBSD and Linux) the expectation seems
to be that the SCSI_DATA (DRQ) bit is live on the Q800 and not latched.
Fortunately we can use the recently introduced mos6522 last_irq_levels variable
which tracks the edge-triggered state to return the SCSI_DATA (DRQ) bit live to

All isabus_dev_print() did was to print up to two IRQ numbers per
device. This is redundant if the IRQ numbers are present as QOM
properties (see e.g. the modified tests/qemu-iotests/172.out).
Now that the last devices relying on isabus_dev_print() had their IRQ
numbers QOM'ified, the contribution of this function ultimately became
redundant. Remove it.

After:

The reason the IRQ number didn's show up before is that this device does not

PIIX3State::pci_irq_levels are redundant which is already tracked by

The IRQ levels in the PCIBus layer are already preserved during
migration. By reusing them and rather than having a redundant implementation

Add the 'bletchley-bmc' machine type based on the kernel DTS[1] and
hardware schematics available to me. The i2c model is as complete as
the current QEMU models support, but in some cases I substituted devices
that are close enough for present functionality. Strap registers are
kept the same as the AST2600-EVB until I'm able to confirm correct
values with physical hardware.
This has been tested with an openbmc image built from [2] plus a kernel

The second bit of IAPC_BOOT_ARCH in FADT table indicates the presence of
keyboard controller implemented as 8042 or equivalent micro controller. This
change enables this flag for microvms if such a device exists (for example,
when added explicitly from the QEMU commandline). Change

enabled this flag for i386 q35 based machines. The reason for doing the same
for micro-vms is to make sure we provide the correct tables to the guest OS
uniformly in all cases when an i8042 device is present. When this bit is not
enabled, guest OSes has to find other indirect methods to detect the device
which we would like to avoid.

The trace_gicv3_icv_hppir_read trace event takes an integer value
which it uses to form the register name, which should be either
ICV_HPPIR0 or ICV_HPPIR1. We were passing in the 'grp' variable for
this, but that is either GICV3_G0 or GICV3_G1NS, which happen to be 0
and 2, which meant that tracing for the ICV_HPPIR1 register was
incorrectly printed as ICV_HPPIR2.
Use the same approach we do for all the other similar trace events,
and pass in 'ri->crm == 8 ? 0 : 1', deriving the index value

The GICv3 has some registers that support byte accesses, and some
that support 8-byte accesses. Our TCG implementation implements all
of this, switching on the 'size' argument and handling the registers
that must support reads of that size while logging an error for
attempted accesses to registers that do not support that size access.
However we forgot to tell the core memory subsystem about this by
specifying the .impl and .valid fields in the MemoryRegionOps struct,
so the core was happily simulating 8 byte accesses by combining two 4
byte accesses. This doesn't have much guest-visible effect, since
there aren't many 8 byte registers and they all support being written
in two 4 byte parts.
Set the .impl and .valid fields to say that all sizes from 1 to 8
bytes are both valid and implemented by the device.

Darwin does not support mknodat. However, to avoid race conditions
with later setting the permissions, we must avoid using mknod on
the full path instead. We could try to fchdir, but that would cause
problems if multiple threads try to call mknodat at the same time.
However, luckily there is a solution: Darwin includes a function
that sets the cwd for the current thread only.
This should suffice to use mknod safely.
This function (pthread_fchdir_np) is protected by a check in
meson in a patch later in this series.

When we still have an AIOCB registered for DMA operations, we try to
settle the respective operation by draining the BlockBackend associated
with the IDE device.
However, this assumes that every DMA operation is associated with an
increment of the BlockBackend’s in-flight counter (e.g. through some
ongoing I/O operation), so that draining the BB until its in-flight
counter reaches 0 will settle all DMA operations. That is not the case:
For TRIM, the guest can issue a zero-length operation that will not
result in any I/O operation forwarded to the BlockBackend, and also not
increment the in-flight counter in any other way. In such a case,
blk_drain() will be a no-op if no other operations are in flight.
It is clear that if blk_drain() is a no-op, the value of
s->bus->dma->aiocb will not change between checking it in the `if`
condition and asserting that it is NULL after blk_drain().
The particular problem is that ide_issue_trim() creates a BH
(ide_trim_bh_cb()) to settle the TRIM request: iocb->common.cb() is
ide_dma_cb(), which will either create a new request, or find the
transfer to be done and call ide_set_inactive(), which clears
s->bus->dma->aiocb. Therefore, the blk_drain() must wait for
ide_trim_bh_cb() to run, which currently it will not always do.
To fix this issue, we increment the BlockBackend's in-flight counter
when the TRIM operation begins (in ide_issue_trim(), when the
ide_trim_bh_cb() BH is created) and decrement it when ide_trim_bh_cb()
is done.

callbacks with ACPI specific ones (acpi_pcihp_device_*plug_cb) and
as result slot stays powered off. It works fine as ACPI hotplug

pxb_map_irq_fn() handled the necessary removal of the swizzle
applied to the PXB interrupts by the bus to which it was attached
but neglected to apply the normal swizzle for PCI root ports
on the expander bridge.
Result of this was on ARM virt, the PME interrupts for a second
RP on a PXB instance were miss-routed to #45 rather than #46.
Tested with a selection of different configurations with 1 to 5
RP per PXB instance. Note on my x86 test setup the PME interrupts
are not triggered so I haven't been able to test this.

Currently the virtio-iommu device must be programmed before it allows
DMA from any PCI device. This can make the VM entirely unusable when a
virtio-iommu driver isn't present, for example in a bootloader that
loads the OS from storage.
Similarly to the other vIOMMU implementations, default to DMA bypassing
the IOMMU during boot. Add a "boot-bypass" property, defaulting to true,
that lets users change this behavior.
Replace the VIRTIO_IOMMU_F_BYPASS feature, which didn't support bypass
before feature negotiation, with VIRTIO_IOMMU_F_BYPASS_CONFIG.
We add the bypass field to the migration stream without introducing
subsections, based on the assumption that this virtio-iommu device isn't
being used in production enough to require cross-version migration at
the moment (all previous version required workarounds since they didn't
support ACPI and boot-bypass).

SC is required for some kernel features like vhost-vDPA. So this patch
implements basic SC feature. The idea is pretty simple, for software
emulated DMA it would be always coherent. In this case we can simple
advertise ECAP_SC bit. For VFIO and vhost, thing will be more much
complicated, so this patch simply fail the IOMMU notifier
registration.
In the future, we may want to have a dedicated notifiers flag or
similar mechanism to demonstrate the coherency so VFIO could advertise
that if it has VFIO_DMA_CC_IOMMU, for vhost kernel backend we don't
need that since it's a software backend.

The commit 04ceb61a40 ("virtio: Fail if iommu_platform is requested, but
unsupported") claims to fail the device hotplug when iommu_platform
is requested, but not supported by the (vhost) device. On the first
glance the condition for detecting that situation looks perfect, but
because a certain peculiarity of virtio_platform it ain't.
In fact the aforementioned commit introduces a regression. It breaks
virtio-fs support for Secure Execution, and most likely also for AMD SEV
or any other confidential guest scenario that relies encrypted guest
memory. The same also applies to any other vhost device that does not
support _F_ACCESS_PLATFORM.
The peculiarity is that iommu_platform and _F_ACCESS_PLATFORM collates
"device can not access all of the guest RAM" and "iova != gpa, thus
device needs to translate iova".
Confidential guest technologies currently rely on the device/hypervisor
offering _F_ACCESS_PLATFORM, so that, after the feature has been
negotiated, the guest grants access to the portions of memory the
device needs to see. So in for confidential guests, generally,
_F_ACCESS_PLATFORM is about the restricted access to memory, but not
about the addresses used being something else than guest physical
addresses.
This is the very reason for which commit f7ef7e6e3b ("vhost: correctly
turn on VIRTIO_F_IOMMU_PLATFORM") fences _F_ACCESS_PLATFORM from the
vhost device that does not need it, because on the vhost interface it
only means "I/O address translation is needed".
This patch takes inspiration from f7ef7e6e3b ("vhost: correctly turn on
VIRTIO_F_IOMMU_PLATFORM"), and uses the same condition for detecting the
situation when _F_ACCESS_PLATFORM is requested, but no I/O translation
by the device, and thus no device capability is needed. In this
situation claiming that the device does not support iommu_plattform=on
is counter-productive. So let us stop doing that!

The current smbios table implementation splits the main memory in 16 GiB
(DIMM like) chunks. With the current smbios table assignment code, we can have
only 512 such chunks before the 16 bit handle numbers in the header for tables
17 and 19 conflict. A guest with more than 8 TiB of memory will hit this
limitation and would fail with the following assertion in isa-debugcon:
ASSERT_EFI_ERROR (Status = Already started)
ASSERT /builddir/build/BUILD/edk2-ca407c7246bf/OvmfPkg/SmbiosPlatformDxe/SmbiosPlatformDxe.c(125): !EFI_ERROR (Status)
This change adds an additional offset between tables 17 and 19 handle numbers
when configuring VMs larger than 8 TiB of memory. The value of the offset is
calculated to be equal to the additional space required to be reserved
in order to accomodate more DIMM entries without the table handles colliding.
In normal cases where the VM memory is smaller or equal to 8 TiB, this offset
value is 0. Hence in this case, no additional handle numbers are reserved and
table handle values remain as before.
Since smbios memory is not transmitted over the wire during migration,
this change can break migration for large memory vms if the guest is in the
middle of generating the tables during migration. However, in those
situations, qemu generates invalid table handles anyway with or without this
fix. Hence, we do not preserve the old bug by introducing compat knobs/machine
types.

qemu_oom_check() is a function which essentially says "if you pass me
a NULL pointer then print a message then abort()". On POSIX systems
the message includes strerror(errno); on Windows it includes the
GetLastError() error value printed as an integer.
Other than in the implementation of qemu_memalign(), we use this
function only in hw/usb/redirect.c, for three checks:
* on a call to usbredirparser_create()
* on a call to usberedirparser_serialize()
* on a call to malloc()
The usbredir library API functions make no guarantees that they will
set errno on errors, let alone that they might set the
Windows-specific GetLastError string. malloc() is documented as
setting errno, not GetLastError -- and in any case the only thing it
might set errno to is ENOMEM. So qemu_oom_check() isn't the right
thing for any of these. Replace them with straightforward
error-checking code. This will allow us to get rid of
qemu_oom_check().

returns error in that case) we don't need to remember the packet.
Avoid using the usb_packet field in OHCIState (as that can be a
waiting async packet on another endpoint) and allocate and use a local
USBPacket for the iso transfer instead. After this we don't have to
care if we're called from a completion callback or not so we can drop
that parameter as well.

xhciwmi.exe is used inside Windows 2022 SVVP tests. This tool called as
'xhciwmi.exe --verify' reports that 'The firmware loaded on this
controller has known bugs and/or compatibility issues'. This is just
a warning but there is no particular sense to ignore it.
This patch just pacifies the tool.
There is a big question whether this change should be put using
machine type mechanics, but at my opinion this would be an overkill.

This adds support for one possible new protection information format
introduced in TP4068 (and integrated in NVMe 2.0): the 64-bit CRC guard
and 48-bit reference tag. This version does not support storage tags.
Like the CRC16 support already present, this uses a software
implementation of CRC64 (so it is naturally pretty slow). But its good
enough for verification purposes.
This may go nicely hand-in-hand with the support that Keith submitted
for the Linux kernel[1].

When we're using KVM, the PSCI implementation is provided by the
kernel, but QEMU has to tell the guest about it via the device tree.
Currently we look at the KVM_CAP_ARM_PSCI_0_2 capability to determine
if the kernel is providing at least PSCI 0.2, but if the kernel
provides a newer version than that we will still only tell the guest
it has PSCI 0.2. (This is fairly harmless; it just means the guest
won't use newer parts of the PSCI API.)
The kernel exposes the specific PSCI version it is implementing via
the ONE_REG API; use this to report in the dtb that the PSCI
implementation is 1.0-compatible if appropriate. (The device tree
binding currently only distinguishes "pre-0.2", "0.2-compatible" and
"1.0-compatible".)

The tsc210x doesn't support anything other than 16-bit reads on the
SPI bus, but the guest can program the SPI controller to attempt
them anyway. If this happens, don't abort QEMU, just log this as
a guest error.
This fixes our machine_arm_n8x0.py:N8x0Machine.test_n800
acceptance test, which hits this assertion.
The reason we hit the assertion is because the guest kernel thinks
there is a TSC2005 on this SPI bus address, not a TSC210x. (The n810
*does* have a TSC2005 at this address.) The TSC2005 supports the
24-bit accesses which the guest driver makes, and the TSC210x does
not (that is, our TSC210x emulation is not missing support for a word
width the hardware can handle). It's not clear whether the problem
here is that the guest kernel incorrectly thinks the n800 has the
same device at this SPI bus address as the n810, or that QEMU's n810
board model doesn't get the SPI devices right. At this late date
there no longer appears to be any reliable information on the web
about the hardware behaviour, but I am inclined to think this is a
guest kernel bug. In any case, we prefer not to abort QEMU for
guest-triggerable conditions, so logging the error is the right thing
to do.

With these interfaces missing, TFM would delegate peripherals 0, 1,
2, 3 and 8, and qemu would ignore the delegation of interface 8, as
it thought interface 4 was eth & USB.
This patch corrects this behavior and allows TFM to delegate the
eth & USB peripheral to NS mode.
(The old QEMU behaviour was based on revision B of the AN547
appnote; revision C corrects this error in the documentation,
and this commit brings QEMU in to line with how the FPGA
image really behaves.)

We can get the job done in spapr_numa_write_assoc_lookup_arrays() a bit
cleaner:
- 'cur_index = int_buf = g_malloc0(..)' is doing a g_malloc0() in the
'int_buf' pointer and making 'cur_index' point to 'int_buf' all in a
single line. No problem with that, but splitting into 2 lines is clearer
to follow
- use g_autofree in 'int_buf' to avoid a g_free() call later on
- 'buf_len' is only being used to store the size of 'int_buf' malloc.
Remove the var and just use the value in g_malloc0() directly
- remove the 'ret' var and just return the result of fdt_setprop()

Use g_autoptr() with GArray* and GString* pointers to avoid calling
g_free() and the need for the 'out' label.
'drc_name' can also be g_autofreed to avoid a g_free() call at the end
of the while() loop.
