When the DSM operation is cancelled asynchronously, we set iocb->ret to
-ECANCELED. However, the callback function only checks the return value
of the completed aio, which may have completed succesfully prior to the
cancellation and thus the callback ends up continuing the dsm operation
instead of bailing out. Fix this.

If the zone reset operation is cancelled but the block unmap operation
completes normally, the callback will continue resetting the next zone
since it neglects to check iocb->ret which will have been set to
-ECANCELED. Make sure that this is checked and bail out if an error is
present.

There are several bugs in the async cancel code for the Format command.
Firstly, cancelling a format operation neglects to set iocb->ret as well
as clearing the iocb->aiocb after cancelling the underlying aiocb which
causes the aio callback to ignore the cancellation. Trivial fix.
Secondly, and worse, because the request is queued up for posting to the
CQ in a bottom half, if the cancellation is due to the submission queue
being deleted (which calls blk_aio_cancel), the req structure is
deallocated in nvme_del_sq prior to the bottom half being schedulued.
Fix this by simply removing the bottom half, there is no reason to defer
it anyway.

..and use for both virtio-user-blk and virtio-user-gpio. This avoids
the circular close by deferring shutdown due to disconnection until a
later point. virtio-user-blk already had this mechanism in place so
generalise it as a vhost-user helper function and use for both blk and
gpio devices.
While we are at it we also fix up vhost-user-gpio to re-establish the
event handler after close down so we can reconnect later.

Commit 02b61f38d3 ("hw/virtio: incorporate backend features in features")
properly negotiates VHOST_USER_F_PROTOCOL_FEATURES with the vhost-user
backend, but we forgot to enable vrings as specified in
docs/interop/vhost-user.rst:
If ``VHOST_USER_F_PROTOCOL_FEATURES`` has not been negotiated, the
ring starts directly in the enabled state.
If ``VHOST_USER_F_PROTOCOL_FEATURES`` has been negotiated, the ring is
initialized in a disabled state and is enabled by
``VHOST_USER_SET_VRING_ENABLE`` with parameter 1.
Some vhost-user front-ends already did this by calling
vhost_ops.vhost_set_vring_enable() directly:
- backends/cryptodev-vhost.c
- hw/net/virtio-net.c
- hw/virtio/vhost-user-gpio.c
But most didn't do that, so we would leave the vrings disabled and some
backends would not work. We observed this issue with the rust version of
virtiofsd [1], which uses the event loop [2] provided by the
vhost-user-backend crate where requests are not processed if vring is
not enabled.
Let's fix this issue by enabling the vrings in vhost_dev_start() for
vhost-user front-ends that don't already do this directly. Same thing
also in vhost_dev_stop() where we disable vrings.

In order to do so in the next commit, pass the buffer size

For QXLCursor in qxl_render_cursor() -> qxl_cursor() we
verify the size of the chunked data ahead, checking we can
access 'sizeof(QXLCursor) + chunk->data_size' bytes.
Since in the SPICE_CURSOR_TYPE_MONO case the cursor is
assumed to fit in one chunk, no change are required.
In SPICE_CURSOR_TYPE_ALPHA the ahead read is handled in
qxl_unpack_chunks().

Currently the intel-hda device has a reset method which manually
resets all the codecs by calling device_legacy_reset() on them. This
means they get reset twice, once because child devices on a qbus get
reset before the parent device's reset method is called, and then
again because we're manually resetting them.
Drop the manual reset call, and ensure that codecs are still reset
when the guest does a reset via ICH6_GCTL_RESET by using
device_cold_reset() (which resets all the devices on the qbus as well
as the device itself) instead of a direct call to the reset function.
This is a slight ordering change because the (only) codec reset now
happens before the controller registers etc are reset, rather than
once before and then once after, but the codec reset function
hda_audio_reset() doesn't care.
This lets us drop a use of device_legacy_reset(), which is
deprecated.

Currently the hcd-xhci-pci and hcd-xhci-sysbus devices, which are
mostly wrappers around the TYPE_XHCI device, which is a direct
subclass of TYPE_DEVICE. Since TYPE_DEVICE devices are not on any
qbus and do not get automatically reset, the wrapper devices both
reset the TYPE_XHCI device in their own reset functions. However,
they do this using device_legacy_reset(), which will reset the device
itself but not any bus it has.
Switch to device_cold_reset(), which avoids using a deprecated
function and also propagates reset along any child buses.

Commit 47a373faa6 (acpi: pc/q35: drop ad-hoc PCI-ISA bridge AML routines and let bus ennumeration generate AML)
moved ISA bridge AML generation to respective devices and was using
aml_alias() to provide PRQx fields in _SB. scope. However, it turned
out that SeaBIOS was not able to process Alias opcode when parsing DSDT,
resulting in lack of keyboard during boot (SeaBIOS console, grub, FreeDOS).
While fix for SeaBIOS is posted
https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/RGPL7HESH5U5JRLEO6FP77CZVHZK5J65/
fixed SeaBIOS might not make into QEMU-7.2 in time.
Hence this workaround that puts PRQx back into _SB scope
and gets rid of aliases in ISA bridge description, so
DSDT will be parsable by broken SeaBIOS.
That brings back hardcoded references to ISA bridge
PCI0.S08.P40C/PCI0.SF8.PIRQ
where middle part now is auto generated based on slot it's
plugged in, but it should be fine as bridge initialization
also hardcodes PCI address of the bridge so it can't ever
move. Once QEMU tree has fixed SeaBIOS blob, we should be able
to drop this part and revert back to alias based approach

Commit 69e1c14aa2 ("virtio: core: vq reset feature negotation support")
enabled VIRTIO_F_RING_RESET by default for all virtio devices.
This feature is not currently emulated by QEMU, so for vhost and
vhost-user devices we need to make sure it is supported by the offloaded
device emulation (in-kernel or in another process).
To do this we need to add VIRTIO_F_RING_RESET to the features bitmap
passed to vhost_get_features(). This way it will be masked if the device
does not support it.
This issue was initially discovered with vhost-vsock and vhost-user-vsock,
and then also tested with vhost-user-rng which confirmed the same issue.
They fail when sending features through VHOST_SET_FEATURES ioctl or
VHOST_USER_SET_FEATURES message, since VIRTIO_F_RING_RESET is negotiated
by the guest (Linux >= v6.0), but not supported by the device.

The Large-Send Task Offload Tx Descriptor (9.2.1 Transmit) has a
Large-Send MSS value where the driver specifies the MSS. See the
datasheet here:
http://realtek.info/pdf/rtl8139cp.pdf
The code ignores this value and uses a hardcoded MSS of 1500 bytes
instead. When the MTU is less than 1500 bytes the hardcoded value
results in IP fragmentation and poor performance.
Use the Large-Send MSS value to correctly size Large-Send packets.
Jason Wang <jasowang@redhat.com> noticed that the Large-Send MSS value
mask was incorrect so it is adjusted to match the datasheet and Linux
8139cp driver.

There are two Tx Descriptor formats called mode 0 and mode 1. The mode
is determined by the Large Send bit.
CP_TX_IPCS (bit 18) is defined in mode 1 but the code checks the bit
unconditionally. In mode 0 bit 18 is part of the Large Send MSS value.
Explicitly check the Large Send bit to distinguish Tx command modes.
This avoids bugs where modes are confused. Note that I didn't find any
actual bugs aside from needlessly computing the IP checksum when the
Large Send bit is enabled.

The device turns the Tx Descriptor into a Tx Status descriptor after
fully reading the descriptor. This involves clearing Tx Own (bit 31) to
indicate that the driver has ownership of the descriptor again as well
as several other bits.
The code keeps the first dword of the Tx Descriptor in the txdw0 local
variable. txdw0 is reused to build the first word of the Tx Status
descriptor. Later on the code uses txdw0 again, incorrectly assuming
that it still contains the first dword of the Tx Descriptor. The tx
offloading code misbehaves because it sees bogus bits in txdw0.
Use a separate local variable for Tx Status and preserve Tx Descriptor
in txdw0.

Trying to run U-Boot for Cubieboard (Allwinner A10) fails because it cannot
access SD card. The problem is that FIFO register in current
allwinner-sdhost implementation is at the address corresponding to
Allwinner H3, but not A10.
Linux kernel is not affected since Linux driver uses DMA access and does
not use FIFO register for reading/writing.
This patch adds new class parameter `is_sun4i` and based on that
parameter uses register at offset 0x100 either as FIFO register (if
sun4i) or as threshold register (if not sun4i; in this case register at
0x200 is FIFO register).
Tested with U-Boot and Linux kernel image built for Cubieboard and
OrangePi PC.

With commit 39f29e5993 ("hw/intc/arm_gicv3: Use correct number of
priority bits for the CPU") the number of priority bits was changed from
the maximum value 8 to typically 5. As a consequence a few of the lowest
bits in ICC_PMR_EL1 becomes RAZ/WI. However prior to this patch one of
these bits was still used since the supplied priority value is masked
before it's eventually right shifted with one bit. So the bit is not
lost as one might expect when the register is read again.
The Linux kernel depends on lowest valid bit to be reset to zero, see
commit 33625282adaa ("irqchip/gic-v3: Probe for SCR_EL3 being clear
before resetting AP0Rn") for details.
So fix this by masking the priority value after it may have been right
shifted by one bit.

The previous fix to virtio_device_started revealed a problem in its
use by both the core and the device code. The core code should be able
to handle the device "starting" while the VM isn't running to handle
the restoration of migration state. To solve this duel use introduce a
new helper for use by the vhost-user backends who all use it to feed a
should_start variable.
We can also pick up a change vhost_user_blk_set_status while we are at
it which follows the same pattern.

In order to use the increased number of cpus, we need to bring smbios
tables in line with the SMBIOS 3.0 specification. This allows us to
introduce core_count2 which acts as a duplicate of core_count if we have
fewer cores than 256, and contains the actual core number per socket if
we have more.
core_enabled2 and thread_count2 fields work the same way.

The motivation of adding vhost-user vhost_dev_start support is to
improve backend configuration speed and reduce live migration VM
downtime.
Today VQ configuration is issued one by one. For virtio net with
multi-queue support, backend needs to update RSS (Receive side
scaling) on every rx queue enable. Updating RSS is time-consuming
(typical time like 7ms).
Implement already defined vhost status and message in the vhost
specification [1].
(a) VHOST_USER_PROTOCOL_F_STATUS
(b) VHOST_USER_SET_STATUS
(c) VHOST_USER_GET_STATUS
Send message VHOST_USER_SET_STATUS with VIRTIO_CONFIG_S_DRIVER_OK for
device start and reset(0) for device stop.
On reception of the DRIVER_OK message, backend can apply the needed setting
only once (instead of incremental) and also utilize parallelism on enabling
queues.
This improves QEMU's live migration downtime with vhost user backend
implementation by great margin, specially for the large number of VQs of 64
from 800 msec to 250 msec.

This patch introduce ECAP_PASID via "x-pasid-mode". Based on the
existing support for scalable mode, we need to implement the following
missing parts:
1) tag VTDAddressSpace with PASID and support IOMMU/DMA translation
with PASID
2) tag IOTLB with PASID
3) PASID cache and its flush
4) PASID based IOTLB invalidation
For simplicity PASID cache is not implemented so we can simply
implement the PASID cache flush as a no and leave it to be implemented
in the future. For PASID based IOTLB invalidation, since we haven't
had L1 stage support, the PASID based IOTLB invalidation is not
implemented yet. For PASID based device IOTLB invalidation, it
requires the support for vhost so we forbid enabling device IOTLB when
PASID is enabled now. Those work could be done in the future.
Note that though PASID based IOMMU translation is ready but no device
can issue PASID DMA right now. In this case, PCI_NO_PASID is used as
PASID to identify the address without PASID. vtd_find_add_as() has
been extended to provision address space with PASID which could be
utilized by the future extension of PCI core to allow device model to
use PASID based DMA translation.
This feature would be useful for:
1) prototyping PASID support for devices like virtio
2) future vPASID work
3) future PRS and vSVA work

We introduce VTDBus structure as an intermediate step for searching
the address space. This works well with SID based matching/lookup. But
when we want to support SID plus PASID based address space lookup,
this intermediate steps turns out to be a burden. So the patch simply
drops the VTDBus structure and use the PCIBus and devfn as the key for
the g_hash_table(). This simplifies the codes and the future PASID
extension.
To prevent being slower for past vtd_find_as_from_bus_num() callers, a
vtd_as cache indexed by the bus number is introduced to store the last
recent search result of a vtd_as belongs to a specific bus.

Early-boot e820 records will be inserted by the bios/efi/early boot
software and be reported to the kernel via insert_resource. Later, when
CXL drivers iterate through the regions again, they will insert another
resource and make the RESERVED memory area a child.
This RESERVED memory area causes the memory region to become unusable,
and as a result attempting to create memory regions with
`cxl create-region ...`
Will fail due to the RESERVED area intersecting with the CXL window.
During boot the following traceback is observed:
0xffffffff81101650 in insert_resource_expand_to_fit ()
0xffffffff83d964c5 in e820__reserve_resources_late ()
0xffffffff83e03210 in pcibios_resource_survey ()
0xffffffff83e04f4a in pcibios_init ()
Which produces a call to reserve the CFMWS area:
(gdb) p *new
$54 = {start = 0x290000000, end = 0x2cfffffff, name = "Reserved",
flags = 0x200, desc = 0x7, parent = 0x0, sibling = 0x0,
child = 0x0}
Later the Kernel parses ACPI tables and reserves the exact same area as
the CXL Fixed Memory Window:
0xffffffff811016a4 in insert_resource_conflict ()
insert_resource ()
0xffffffff81a81389 in cxl_parse_cfmws ()
0xffffffff818c4a81 in call_handler ()
acpi_parse_entries_array ()
(gdb) p/x *new
$59 = {start = 0x290000000, end = 0x2cfffffff, name = "CXL Window 0",
flags = 0x200, desc = 0x0, parent = 0x0, sibling = 0x0,
child = 0x0}
This produces the following output in /proc/iomem:
590000000-68fffffff : CXL Window 0
590000000-68fffffff : Reserved
This reserved area causes `get_free_mem_region()` to fail due to a check
against `__region_intersects()`. Due to this reserved area, the
intersect check will only ever return REGION_INTERSECTS, which causes
`cxl create-region` to always fail.

There were several different ways to deal with the situation where the
vector specified for a msix function is out of bound:
- early return a function and keep progresssing
- propagate the error to the caller
- mark msix unusable
- assert it is in bound
- just ignore
An out-of-bound vector should not be specified if the device
implementation is correct so let msix functions always assert that the
specified vector is in range.
An exceptional case is virtio-pci, which allows the guest to configure
vectors. For virtio-pci, it is more appropriate to introduce its own
checks because it is sometimes too late to check the vector range in
msix functions.

PS:
Forward 'usage' usualy is fine as long as it's hidden within

PCI-ISA bridges that are built in PIIX/Q35 are building its own AML
using AcpiDevAmlIf interface. Now build_append_pci_bus_devices()
gained AcpiDevAmlIf interface support to get AML of devices atached
to PCI slots.
So drop ad-hoc build_q35_isa_bridge()/build_piix4_isa_bridge()
and let PCI bus enumeration to include PCI-ISA bridge AML
when it's enumerated by build_append_pci_bus_devices().
AML change is mostly contextual, which moves whole ISA hierarchy
directly under PCI host bridge instead of it being described
as separate \SB.PCI0.ISA block.
Note:
If bus/slot that hosts ISA bridge has BSEL set, it will gain new
ASUN and _DMS entries (i.e. acpi-index support, but it should not
cause any functional change and that is fine from PCI Firmware
spec point of view), potentially it's possible to suppress that
by adding a flag to PCIDevice but I don't see a reason to do that
yet, I'd rather treat bridge just as any other PCI device if it's

NB2:
Some targets (or1k) do not support acpi and CONFIG_ACPI is off for them.
However, modules are reused between all architectures so CONFIG_ACPI is
on. For those architectures, dummy stub function definitions help to
resolve symbols. This change uses more of these and so it adds a couple
of dummy stub definitions so that symbols for those can be resolved.

vhost backend sends host notification for every VQ. If backend creates
VQs in parallel, the VHOST_USER_SLAVE_VRING_HOST_NOTIFIER_MSG may
arrive to QEMU in different order than incremental queue index order.
For example VQ 1's message arrive earlier than VQ 0's:
After alloc VhostUserHostNotifier for VQ 1. GPtrArray becomes
[ nil, VQ1 pointer ]
After alloc VhostUserHostNotifier for VQ 0. GPtrArray becomes
[ VQ0 pointer, nil, VQ1 pointer ]
This is wrong. fetch_notifier will return NULL for VQ 1 in
vhost_user_get_vring_base, causes host notifier miss removal(leak).
The fix is to remove current element from GPtrArray, make the right
position for element to insert.

Support queue_enable in vhost-kernel scenario. It can be called when
a vq reset operation has been performed and the vq is restared.
It should be noted that we can restart the vq when the vhost has
already started. When launching a new vhost device, the vhost is not
started and all vqs are not initalized until VIRTIO_PCI_COMMON_STATUS
is written. Thus, we should use vhost_started to differentiate the
two cases: vq reset and device start.
Currently it only supports vhost-kernel.

In theory the virtio-iommu-pci could be plugged anywhere in the PCIe
topology and as long as the dt/acpi info are properly built this should
work. However at the moment we fail to do that because the
virtio-iommu-pci BDF is not computed at plug time and in that case
vms->virtio_iommu_bdf gets an incorrect value.
For instance if the virtio-iommu-pci is plugged onto a pcie root port
and the virtio-iommu protects a virtio-block-pci device the guest does
not boot.
So let's do not pretend we do support this case and fail the initialize()
if we detect the virtio-iommu-pci is plugged anywhere else than on the
root bus. Anyway this ability is not needed.

PCIE Base Specification r6.0 6.3 Data Object Exchange
Supports multiple DOE PCIe Extended Capabilities for a single PCIe

to pcie_doe_init(). The protocols in that array will be registered under
the DOE capability structure. For each protocol, vendor ID, type, and
corresponding callback function (handle_request()) should be implemented.
This callback function represents how the DOE request for corresponding
protocol will be handled.
pcie_doe_{read/write}_config() must be appended to corresponding PCI
device's config_read/write() handler to enable DOE access. In
pcie_doe_read_config(), false will be returned if pci_config_read()
offset is not within DOE capability range. In pcie_doe_write_config(),

If we encounter a new mapping while the number of available DMA entries
in vfio is 0, we are currently skipping that mapping which is a problem
if we manage to free up DMA space after that within the same RPCIT --
we will return to the guest with CC0 and have not mapped everything
within the specified range. This issue was uncovered while testing
changes to the s390 linux kernel iommu/dma code, where a different
usage pattern was employed (new mappings start at the end of the
aperture and work back towards the front, making us far more likely
to encounter new mappings before invalidated mappings during a
global refresh).
Fix this by tracking whether any mappings were skipped due to vfio
DMA limit hitting 0; when this occurs, we still continue the range
and unmap/map anything we can - then we must re-run the range again
to pickup anything that was missed. This must occur in a loop until
all requests are satisfied (success) or we detect that we are still
unable to complete all mappings (return ZPCI_RPCIT_ST_INSUFF_RES).

Revert the control and flag bits in the subchannel status word in case
the SSCH operation fails with non-zero CC (ditto for CSCH and HSCH).
According to POPS, the control and flag bits are only changed if SSCH,
CSCH, and HSCH return CC 0, and no other action should be taken otherwise.
In order to simulate that after the fact, the bits need to be reverted on
non-zero CC.
While the do_subchannel_work logic for virtual (virtio) devices will
return condition code 0, passthrough (vfio) devices may encounter
errors from either the host kernel or real hardware that need to be
accounted for after this point. This includes restoring the state of
the Subchannel Status Word to reflect the subchannel, as these bits

affected instructions.
Experimentation has shown that a failure on a START SUBCHANNEL (SSCH)
to a passthrough device would leave the subchannel with the START
PENDING activity control bit set, thus blocking subsequent SSCH
operations in css_do_ssch() until some form of error recovery was
undertaken since no interrupt would be expected.

improve error handling during module load, by changing:
bool module_load(const char *prefix, const char *lib_name);
void module_load_qom(const char *type);
to:
int module_load(const char *prefix, const char *name, Error **errp);
int module_load_qom(const char *type, Error **errp);
where the return value is:
-1 on module load error, and errp is set with the error
0 on module or one of its dependencies are not installed
1 on module load success
2 on module load success (module already loaded or built-in)
module_load_qom_one has been introduced in:
commit 28457744c3 ("module: qom module support"), which built on top of
module_load_one, but discarded the bool return value. Restore it.
Adapt all callers to emit errors, or ignore them, or fail hard,
as appropriate in each context.
Replace the previous emission of errors via fprintf in _some_ error
conditions with Error and error_report, so as to emit to the appropriate
target.
A memory leak is also fixed as part of the module_load changes.
audio: when attempting to load an audio module, report module load errors.
Note that still for some callers, a single issue may generate multiple
error reports, and this could be improved further.
Regarding the audio code itself, audio_add() seems to ignore errors,
and this should probably be improved.
block: when attempting to load a block module, report module load errors.
For the code paths that already use the Error API, take advantage of those
to report module load errors into the Error parameter.
For the other code paths, we currently emit the error, but this could be
improved further by adding Error parameters to all possible code paths.
console: when attempting to load a display module, report module load errors.
qdev: when creating a new qdev Device object (DeviceState), report load errors.
If a module cannot be loaded to create that device, now abort execution
(if no CONFIG_MODULE) or exit (if CONFIG_MODULE).
qom/object.c: when initializing a QOM object, or looking up class_by_name,
report module load errors.
qtest: when processing the "module_load" qtest command, report errors
in the load of the module.

When we direct boot a kernel on a CPU which emulates EL3, we need to
set up the EL3 system registers as the Linux kernel documentation
specifies:
https://www.kernel.org/doc/Documentation/arm64/booting.rst
For CPUs with FEAT_HCX support this includes:
- SCR_EL3.HXEn (bit 38) must be initialised to 0b1.
but we forgot to do this when implementing FEAT_HCX, which would mean
that a guest trying to access the HCRX_EL2 register would crash.

When we direct boot a kernel on a CPU which emulates EL3, we need
to set up the EL3 system registers as the Linux kernel documentation
specifies:
https://www.kernel.org/doc/Documentation/arm64/booting.rst
For SVE and SME this includes:
- ZCR_EL3.LEN must be initialised to the same value for all CPUs the
kernel is executed on.
- SMCR_EL3.LEN must be initialised to the same value for all CPUs the
kernel will execute on.
Although we are technically compliant with this, the "same value" we
currently use by default is the reset value of 0. This will end up
forcing the guest kernel's SVE and SME vector length to be only the
smallest supported length.
Initialize the vector length fields to their maximum possible value,
which is 0xf. If the implementation doesn't actually support that
vector length then the effective vector length will be constrained
down to the maximum supported value at point of use.
This allows the guest to use all the vector lengths the emulated CPU
supports (by programming the _EL2 and _EL1 versions of these
registers.)

e820 reserved entries were used before the dynamic entries with fw config files
were intoduced. Please see the following change:
7d67110f2d9a6("pc: add etc/e820 fw_cfg file")
Identical support was introduced into seabios as well with the following commit:
ce39bd4031820 ("Add support for etc/e820 fw_cfg file")
Both the above commits are now quite old. QEMU machines 1.7 and newer no longer
use the reserved entries. Seabios uses fw config files and
dynamic e820 entries by default and only falls back to using reserved entries
when it has to work with old qemu (versions earlier than 1.7). Please see
functions qemu_cfg_e820() and qemu_early_e820(). It is safe to remove legacy
FW_CFG_E820_TABLE and associated code now as QEMU 7.0 has deprecated i440fx
machines 1.7 and older. It would be incredibly rare to run the latest qemu
version with a very old version of seabios that did not support fw config files
for e820.
As far as I could see, edk2/ovfm never supported reserved entries and uses fw
config files from the beginning. So there should be no incompatibilities with
ovfm as well.

By storing the device pointers in a variable with the right type the
number of QOM casts can be reduced which also makes the code more
readable.

Several variables are set in if-else branches where the else branch
can be removed by setting a default value at the variable declaration
which leads to simlpler code that is easier to follow.

Values not used frequently enough may not worth putting in a local
variable, especially with names almost as long as the original value
because that does not improve readability, to the contrary it makes it
harder to see what value is used. Drop a few such variables. This is
the same clean up that was done for mac_oldworld in commit b8df32555c.
