There is currently a check in esp_select() to cancel any in-flight SCSI requests
to ensure that issuing multiple select commands without continuing through the
rest of the ESP state machine ignores all but the last SCSI request. This is
also enforced through the addition of assert()s in esp_transfer_data() and
scsi_read_data().
The get_cmd() function does not call esp_select() when TC == 0 which means it is
possible for a fuzzer to trigger these assert()s by sending a select command when
TC == 0 immediately after a valid SCSI CDB has been submitted.
Since esp_select() is only called from get_cmd(), hoist the check to cancel
in-flight SCSI requests from esp_select() into get_cmd() to ensure it is always
called when executing a select command to initiate a new SCSI request.

Since commit d8fb7d0969 ("vl: switch -M parsing to keyval"), machine
parameter definitions cannot use underscores, because keyval_dashify()
transforms them to dashes and the parser doesn't find the parameter.
This affects option default_bus_bypass_iommu which was introduced in the
same release:
$ qemu-system-x86_64 -M q35,default_bus_bypass_iommu=on
qemu-system-x86_64: Property 'pc-q35-6.1-machine.default-bus-bypass-iommu' not found
Rename the parameter to "default-bus-bypass-iommu". Passing
"default_bus_bypass_iommu" is still valid since the underscore are
transformed automatically.

The LBA28 capacity (at offsets 60/61 of identification) is supposed to
express the maximum size supported by LBA28 commands. If the device is
larger than this, we have to cap it to 2^28-1.
At least NetBSD happens to be using this value to determine whether to use
LBA28 or LBA48 for its commands, using LBA28 for sectors that don't need
LBA48. This commit thus fixes NetBSD access to disks larger than 128GiB.

Allow instantiating a virtio-iommu device by adding an ACPI Virtual I/O
Translation table (VIOT), which describes the relation between the
virtio-iommu and the endpoints it manages.
Add a hotplug handler for virtio-iommu on x86 and set the necessary
reserved region property. On x86, the [0xfee00000, 0xfeefffff] DMA
region is reserved for MSIs. DMA transactions to this range either
trigger IRQ remapping in the IOMMU or bypasses IOMMU translation.
Although virtio-iommu does not support IRQ remapping it must be informed
of the reserved region so that it can forward DMA transactions targeting
this region.

PCMachineState, so it can be shared between all three vIOMMUs.
The x86_iommu_get_default() helper is still needed by KVM and IOAPIC to
fetch the default IRQ-remapping IOMMU. Since virtio-iommu doesn't
support IRQ remapping, this interface doesn't need to change for the
moment. We could later replace X86IOMMUState with an "IRQ remapping

that used to be discarded will get re-populated and if we
discard+re-access memory after mapping+pinning, the pages mapped into the

space page tables.
Set discarding of RAM broken such that:
- virtio-mem and vhost-vdpa run mutually exclusive
- virtio-balloon is inhibited and no memory discards will get issued
In the future, we might be able to support coordinated discarding of RAM
as used by virtio-mem and already supported by vfio via the

Now that we check sysbus device types during device creation, we

This was the only thing done by this notifier, so we remove the
whole sysbus_notifier structure of the MachineState.
Note: This notifier was checking all /peripheral and /peripheral-anon
sysbus devices. Now we only check those added by -device cli option or
device_add qmp command when handling the command/option. So if there
are some devices added in one of these containers manually (eg in
machine C code), these will not be checked anymore.
This use case does not seem to appear apart from

not for a sysbus device, so it's ok).

The MSI-X structures of some devices and other non-MSI-X structures
may be in the same BAR. They may share one host page, especially in
the case of large page granularity, such as 64K.
For example, MSIX-Table size of 82599 NIC is 0x30 and the offset in
Bar 3(size 64KB) is 0x0. vfio_listener_region_add() will be called
to map the remaining range (0x30-0xffff). If host page size is 64KB,
it will return early at 'int128_ge((int128_make64(iova), llend))'
without any message. Let's add a trace point to inform users like commit
5c08600547 ("vfio: Use a trace point when a RAM section cannot be DMA mapped")
did.

We can expand MemoryRegions of sub-page MMIO BARs in
vfio_pci_write_config() to improve IO performance for some
devices. However, the MemoryRegions of destination VM are
not expanded any more after live migration. Because their
addresses have been updated in vmstate_load_state()
(vfio_pci_load_config) and vfio_sub_page_bar_update_mapping()
will not be called.
This may result in poor performance after live migration.
So iterate BARs in vfio_pci_load_config() and try to update
sub-page BARs.

Replace fprintf with qemu_log_mask LOG_GUEST_ERROR as the intention is
to handle valid accesses in these functions so if we get to these
errors then it's an invalid access. Do not abort as that would allow
the guest to crash QEMU and the practice in other devices is to not do
that just log and ignore the invalid access. While at it also simplify
the complex bit ops to check if a return value was set which can be

When client sent a 9p Tgetattr request then the wrong I/O block
size value was returned by 9p server; instead of host file
system's I/O block size it should rather return an I/O block
size according to 9p session's 'msize' value, because the value
returned to client should be an "optimum" block size for I/O
(i.e. to maximize performance), it should not reflect the actual
physical block size of the underlying storage media.
The I/O block size of a host filesystem is typically 4k, so the
value returned was far too low for good 9p I/O performance.
This patch adds stat_to_iounit() with a similar approach as the
existing get_iounit() function.

Add the Processor Properties Topology Table (PPTT) used to
describe CPU topology information to ACPI guests.
Note, a DT-boot Linux guest with a non-flat CPU topology will
see socket and core IDs being sequential integers starting
from zero, which is different from ACPI-boot Linux guest,
e.g. with -smp 4,sockets=2,cores=2,threads=1
a DT boot produces:
cpu: 0 package_id: 0 core_id: 0
cpu: 1 package_id: 0 core_id: 1
cpu: 2 package_id: 1 core_id: 0
cpu: 3 package_id: 1 core_id: 1
an ACPI boot produces:
cpu: 0 package_id: 36 core_id: 0
cpu: 1 package_id: 36 core_id: 1
cpu: 2 package_id: 96 core_id: 2
cpu: 3 package_id: 96 core_id: 3
This is due to several reasons:
1) DT cpu nodes do not have an equivalent field to what the PPTT
ACPI Processor ID must be, i.e. something equal to the MADT CPU
UID or equal to the UID of an ACPI processor container. In both
ACPI cases those are platform dependant IDs assigned by the
vendor.
2) While QEMU is the vendor for a guest, if the topology specifies
SMT (> 1 thread), then, with ACPI, it is impossible to assign a
core-id the same value as a package-id, thus it is not possible
to have package-id=0 and core-id=0. This is because package and
core containers must be in the same ACPI namespace and therefore
must have unique UIDs.
3) ACPI processor containers are not mandatorily required for PPTT
tables to be used and, due to the limitations of which IDs are
selected described above in (2), they are not helpful for QEMU,
so we don't build them with this patch. In the absence of them,
Linux assigns its own unique IDs. The maintainers have chosen not
to use counters from zero, but rather ACPI table offsets, which
explains why the numbers are so much larger than with DT.
4) When there is no SMT (threads=1) the core IDs for ACPI boot guests
match the logical CPU IDs, because these IDs must be equal to the
MADT CPU UID (as no processor containers are present), and QEMU
uses the logical CPU ID for these MADT IDs.
So in summary, with QEMU as the vendor for the guests, we simply
use sequential integers starting from zero for the non-leaf nodes
but with ID-valid flag unset, so that guest will ignore them and
use table offsets as unique container IDs. And we use logical CPU
IDs for the leaf nodes with the ID-valid flag set, which will be
consistent with MADT.
Currently the implementation of PPTT generation complies with ACPI
specification 5.2.29 (Revision 6.3). The 6.3 spec can be found at:

Support device tree CPU topology descriptions.
In accordance with the Devicetree Specification, the Linux Doc
"arm/cpus.yaml" requires that cpus and cpu nodes in the DT are
present. And we have already met the requirement by generating
/cpus/cpu@* nodes for members within ms->smp.cpus. Accordingly,
we should also create subnodes in cpu-map for the present cpus,
each of which relates to an unique cpu node.
The Linux Doc "cpu/cpu-topology.txt" states that the hierarchy
of CPUs in a SMP system is defined through four entities and
they are socket/cluster/core/thread. It is also required that
a socket node's child nodes must be one or more cluster nodes.
Given that currently we are only provided with information of
socket/core/thread, we assume there is one cluster child node
in each socket node when creating cpu-map.

On existing older machine types, without cpu topology described
in ACPI or DT, the guest will populate one by default. With the
topology described, it will read the information and set up its
topology as instructed, but that may not be the same as what was
getting used by default. It's possible that an user application
has a dependency on the default topology and if the default one
gets changed it will probably behave differently.
Based on above consideration we'd better only describe topology
information to the guest on 6.2 and later machine types.

Recent Linux kernels are accessing the PCI device in slot 0 that
represents the PCI host bridge. This causes ppc4xx_pci_map_irq()
to return -1 which causes an assert() later:
hw/pci/pci.c:262: pci_bus_change_irq_level: Assertion `irq_num >= 0' failed.
Thus we should allocate an IRQ line for the device in slot 0, too.
To avoid changes to the outside of ppc4xx_pci.c, we map it to
the internal IRQ number 4 which will then happily be ignored since
ppc440_bamboo.c does not wire it up.
With these changes it is now possible again to use recent Linux
kernels for the bamboo board.

access them via their memory region. This is not a problem at reset

qemu-system-aarch64: FDT: Failed to create subnode /memory@80000000: FDT_ERR_EXISTS
As specified by linux device-tree binding document, the device-tree
nodes for these empty NUMA nodes shouldn't be generated. However,
the corresponding NUMA node IDs should be included in the distance
map. The memory hotplug through device-tree on ARM64 isn't existing
so far and it's not necessary to require the user to provide a distance
map. Furthermore, the default distance map Linux generates may even be
sufficient. So this simply skips populating the device-tree nodes for
these empty NUMA nodes to avoid the error, so that QEMU can be started
successfully.

"failover_pair_id", before calling the generic mechanism.
It's not needed (and not generic) to do that in qdev_device_add() because
this is also checked by the failover_hide_primary_device() function that

The hide_device helper can be called several times for the same
devices as it shouldn't change any state and should only return an
information.
But not to rely anymore on QemuOpts we have introduced a new field
to store the parameters of the device and don't allow to update it
once it is done.
And as the function is called several times, we ends with:
warning: Cannot attach more than one primary device to 'virtio0'
That is not only a warning as it prevents to hide the device and breaks
failover.
Fix that by checking the device id.
Now, we fail only if the virtio-net device is really used by two different
devices, for instance:
-device virtio-net-pci,id=virtio0,failover=on,... \
-device vfio-pci,id=hostdev0,failover_pair_id=virtio0,... \
-device e1000e,id=e1000e0,failover_pair_id=virtio0,... \
will exit with:
Cannot attach more than one primary device to 'virtio0': 'hostdev0' and 'e1000e0'

Don't go through the global QemuOptsList, it is state of the legacy
command line parser and we will create devices that are not contained
in it. It is also just the command line configuration and not
necessarily the current runtime state.
Instead, look at the qdev device tree which has the current state of all
existing devices.

Instead of accessing the global QemuOptsList, which really belong to the
command line parser and shouldn't be accessed from devices, store a
pointer to the QemuOpts in a new VirtIONet field.
This is not the final state, but just an intermediate step to get rid of
QemuOpts in devices. It will later be replaced with an options QDict.
Before this patch, two "primary" devices could be hidden for the same
standby device, but only one of them would actually be enabled and the
other one would be kept hidden forever, so this doesn't make sense.
After this patch, configuring a second primary device is an error.

hide_device() is used for virtio-net failover, where the standby virtio
device delays creation of the primary device. It only makes sense to
have a single primary device for each standby device. Adding a second
one should result in an error instead of hiding it and never using it
afterwards.
Prepare for this by adding an Error parameter to the hide_device()
callback where virtio-net is informed about adding a primary device.

qdev_set_id() is mostly used when the user adds a device (using
-device cli option or device_add qmp command). This commit adds
an error parameter to handle the case where the given id is
already taken.
Also document the function and add a return value in order to
be able to capture success/failure: the function now returns the
id in case of success, or NULL in case of failure.
The commit modifies the 2 calling places (qdev-monitor and
xen-legacy-backend) to add the error object parameter.
Note that the id is, right now, guaranteed to be unique because
all ids came from the "device" QemuOptsList where the id is used
as key. This addition is a preparation for a future commit which
will relax the uniqueness.

Some network backends (vhost-user and vhost-vdpa) work only with
specific devices. At startup, they second guess what the command line
option handling will do and error out if they think a non-virtio device
will attach to them.
This second guessing is not only ugly, it can lead to wrong error
messages ('-device floppy,netdev=foo' should complain about an unknown
property, not about the wrong kind of network device being attached) and
completely ignores hotplugging.
Add a callback where backends can check compatibility with a device when
it actually tries to attach, even on hotplug.

The gpio array is declared as a dense array:
qemu_irq gpios[ASPEED_GPIO_NR_PINS];
(AST2500 has 228, AST2400 has 216, AST2600 has 208)
However, this array is used like a matrix of GPIO sets
(e.g. gpio[NR_SETS][NR_PINS_PER_SET] = gpio[8][32])
size_t offset = set * GPIOS_PER_SET + gpio;
qemu_set_irq(s->gpios[offset], !!(new & mask));
This can result in an out-of-bounds access to "s->gpios" because the
gpio sets do _not_ have the same length. Some of the groups (e.g.
GPIOAB) only have 4 pins. 228 != 8 * 32 == 256.
To fix this, I converted the gpio array from dense to sparse, to that
match both the hardware layout and this existing indexing code.

Some of the pin declarations in the Aspeed GPIO module were incorrect,
probably because of confusion over which bits in the input and output
uint32_t's correspond to which groups in the label array. Since the
uint32_t literals are in big endian, it's sort of the opposite of what
would be intuitive. The least significant bit in ast2500_set_props[6]
corresponds to GPIOY0, not GPIOAB7.
GPIOxx indicates input and output capabilities, GPIxx indicates only
input, GPOxx indicates only output.
AST2500:
- Previously had GPIW0..GPIW7 and GPIX0..GPIX7, that's correct.
- Previously had GPIOY0..GPIOY3, should have been GPIOY0..GPIOY7.
- Previously had GPIOAB0..GPIOAB3 and GPIAB4..GPIAB7, should only have
been GPIOAB0..GPIOAB3.
AST2600:
- GPIOT0..GPIOT7 should have been GPIT0..GPIT7.
- GPIOU0..GPIOU7 should have been GPIU0..GPIU7.
- GPIW0..GPIW7 should have been GPIOW0..GPIOW7.
- GPIOY0..GPIOY7 and GPIOZ0...GPIOZ7 were disabled.

The Aspeed SoCs have a dual boot function for firmware fail-over
recovery. The system auto-reboots from the second flash if the main
flash does not boot successfully within a certain amount of time. This
function is called alternate boot (ABR) in the FMC controllers.
On AST2400/AST2500, ABR is enabled by hardware strapping in SCU70 to
enable the 2nd watchdog timer, on AST2600, through register SCU510.
If the boot on the the main flash succeeds, the firmware should
disable the 2nd watchdog timer. If not, the BMC is reset and the CE0
and CE1 mappings are swapped to restart the BMC from the 2nd flash.
On the AST2600, the ABR registers controlling the 2nd watchdog timer
were moved from the watchdog register to the FMC controller and the
FMC model should be able to control WDT2 through its own register set.
This requires more work. For now, add dummy read/write handlers to let
the FW disable the 2nd watchdog without error.

As ! has higher precedence over & (bitwise and), this is essentially

- Embed SerialMM in MchpPfSoCMMUartState and QOM-initialize it
- Alias SERIAL_MM 'chardev' property on MCHP_PFSOC_UART
- Forward SerialMM sysbus IRQ in mchp_pfsoc_mmuart_realize()
- Add DeviceReset() method
- Add vmstate structure for migration
- Register device in 'input' category
- Keep mchp_pfsoc_mmuart_create() behavior
Note, serial_mm_init() calls qdev_set_legacy_instance_id().
This call is only needed for backwards-compatibility of incoming
migration data with old versions of QEMU which implemented migration
of devices with hand-rolled code. Since this device didn't previously
handle migration at all, then it doesn't need to set the legacy
instance ID.

Our device have 2 different I/O regions:
- a 16550 UART mapped for 32-bit accesses
- 13 extra registers
Instead of mapping each region on the main bus, introduce
a container, map the 2 devices regions on the container,
and map the container on the main bus.

The current MCHP_PFSOC_MMUART_REG_SIZE definition represent the
size occupied by all the registers. However all registers are
32-bit wide, and the MemoryRegionOps handlers are restricted to
32-bit:
static const MemoryRegionOps mchp_pfsoc_mmuart_ops = {
.read = mchp_pfsoc_mmuart_read,
.write = mchp_pfsoc_mmuart_write,
.impl = {
.min_access_size = 4,
.max_access_size = 4,
},
Avoid being triskaidekaphobic, simplify by using the number of
registers.

Linux limits the size of iovecs to 1024 (UIO_MAXIOV in the kernel
sources, IOV_MAX in POSIX). Because of this, on some host adapters
requests with many iovecs are rejected with -EINVAL by the
io_submit() or readv()/writev() system calls.
In fact, the same limit applies to SG_IO as well. To fix both the
EINVAL and the possible performance issues from using fewer iovecs
than allowed by Linux (some HBAs have max_segments as low as 128),
introduce a separate entry in BlockLimits to hold the max_segments
value from sysfs. This new limit is used only for SG_IO and clamped
to bs->bl.max_iov anyway, just like max_hw_transfer is clamped to
bs->bl.max_transfer.

The subsection name for page-poison was typo'd as:
vitio-balloon-device/page-poison
Note the missing 'r' in virtio.
When we have a machine type that enables page poison, and the guest
enables it (which needs a new kernel), things fail rather unpredictably.
The fallout from this is that most of the other subsections fail to
load, including things like the feature bits in the device, one
possible fallout is that the physical addresses of the queues
then get aligned differently and we fail with an error about
last_avail_idx being wrong.
It's not obvious to me why this doesn't produce a more obvious failure,
but virtio's vmstate loading is a bit open-coded.
