The arm boot.c code includes a utility function write_bootloader()
which assists in writing a boot-code fragment into guest memory,
including handling endianness and fixing it up with entry point
addresses and similar things. This is useful not just for the boot.c
code but also in board model code, so rename it to
arm_write_bootloader() and make it globally visible.
Since we are making it public, make its API a little neater: move the
AddressSpace* argument to be next to the hwaddr argument, and allow
the fixupcontext array to be const, since we never modify it in this
function.

The 'singlestep' HMP command is confusing, because it doesn't
actually have anything to do with single-stepping the CPU. What it
does do is force TCG emulation to put one guest instruction in each
TB, which can be useful in some situations.
Create a new HMP command 'one-insn-per-tb', so we can document that
'singlestep' is just a deprecated synonym for it, and eventually
perhaps drop it.
We aren't obliged to do deprecate-and-drop for HMP commands,
but it's easy enough to do so, so we do.

The only place left that looks at the old 'singlestep' global
variable is the TCG curr_cflags() function. Replace the old global
with a new 'one_insn_per_tb' which is defined in tcg-all.c and
declared in accel/tcg/internal.h. This keeps it restricted to the
TCG code, unlike 'singlestep' which was available to every file in
the system and defined in multiple different places for softmmu vs
linux-user vs bsd-user.
While we're making this change, use qatomic_read() and qatomic_set()
on the accesses to the new global, because TCG will read it without
holding a lock.

This query copies the kernel command line into the message buffer. It
was previously stubbed out to return empty, this commit makes it reflect
the arguments specified with `-append`.
I observed the following peculiarities on my Pi 3B+:
- If the buffer is shorter than the string, the response header gives
the full length, but no data is actually copied.
- No NUL terminator is added: even if the buffer is long enough to fit
one, the buffer's original contents are preserved past the string's
end.
- The VC firmware adds the following extra parameters beside the
user-supplied ones (via /boot/cmdline.txt): `video`, `vc_mem.mem_base`
and `vc_mem.mem_size`. This is currently not implemented in qemu.

thread_pool_submit_aio() is always called on a pool taken from
qemu_get_current_aio_context(), and that is the only intended
use: each pool runs only in the same thread that is submitting
work to it, it can't run anywhere else.
Therefore simplify the thread_pool_submit* API and remove the

Previously, PXB_CXL_DEVICE, PXB_PCIE_DEVICE and PXB_DEVICE all
have PCI_DEVICE as their direct parent but share a common state
struct PXBDev. convert_to_pxb() is used to get the PXBDev
instance from which ever of these types it is called on.
This patch switches to an explicit hierarchy based on shared
functionality. To allow use of OBJECT_DECLARE_SIMPLE_TYPE()
whilst minimizing code changes, all types are renamed to have
the postfix _DEV rather than _DEVICE. The new heirarchy
has PXB_CXL_DEV with parent PXB_PCIE_DEV which in turn
has parent PXB_DEV which continues to have parent PCI_DEVICE.
This allows simple use of PXB_DEV() etc rather than a custom function
+ removal of duplicated properties and moving the CXL specific
elements out of struct PXBDev.

i440fx machine versions 2.3 and newer supports dynamic ram
resizing. See commit a1666142db ("acpi-build: make ROMs RAM blocks resizeable") .
Currently supported all q35 machine types (versions 2.4 and newer) supports
resizable RAM/ROM blocks.Therefore the warning generated when the ACPI table
size exceeds a pre-defined value does not apply to those machine versions.
Add a check limiting the warning message to only those machines that does not
support expandable ram blocks (that is, i440fx machines with version 2.2
and older).

This patch provides accessor functions as replacements for direct
access to slot_reserved_mask according to the comment at the top
of include/hw/pci/pci_bus.h which advises that data structures for
PCIBus should not be directly accessed but instead be accessed using
accessor functions in pci.h.
Three accessor functions can conveniently replace all direct accesses
of slot_reserved_mask. With this patch, the new accessor functions are
used in hw/sparc64/sun4u.c and hw/xen/xen_pt.c and pci_bus.h is removed
from the included header files of the same two files.
No functional change intended.

Optimize the virtio-balloon feature on the ARM platform by adding
a variable to keep track of the current hot-plugged pc-dimm size,
instead of traversing the virtual machine's memory modules to count
the current RAM size during the balloon inflation or deflation
process. This variable can be updated only when plugging or unplugging
the device, which will result in an increase of approximately 60%
efficiency of balloon process on the ARM platform.
We tested the total amount of time required for the balloon inflation process on ARM:
inflate the balloon to 64GB of a 128GB guest under stress.

When a virtqueue size is changed by the guest via
virtio_queue_set_num(), its region cache is not automatically updated.
If the size was increased, this could lead to accessing the cache out
of bounds. For example, in vring_get_used_event():
static inline uint16_t vring_get_used_event(VirtQueue *vq)
{
return vring_avail_ring(vq, vq->vring.num);
}
static inline uint16_t vring_avail_ring(VirtQueue *vq, int i)
{
VRingMemoryRegionCaches *caches = vring_get_region_caches(vq);
hwaddr pa = offsetof(VRingAvail, ring[i]);
if (!caches) {
return 0;
}
return virtio_lduw_phys_cached(vq->vdev, &caches->avail, pa);
}
vq->vring.num will be greater than caches->avail.len, which will
trigger a failed assertion down the call path of
virtio_lduw_phys_cached().
Fix this by calling virtio_init_region_cache() after
virtio_queue_set_num() if we are not already calling
virtio_queue_set_rings(). In the legacy path this is already done by
virtio_queue_update_rings().

Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices. I2C model only supports
TPM2 protocol.
This commit includes changes for the common code.
- Added I2C emulation model. Logic was added in the model to temporarily
cache the data as I2C interface works per byte basis.
- New tpm type "tpm-tis-i2c" added for I2C support. The user has to
provide this string on command line.
Testing:
TPM I2C device module is tested using SWTPM (software based TPM
package). Qemu uses the rainier machine and is connected to swtpm over
the socket interface.
The command to start swtpm is as follows:
$ swtpm socket --tpmstate dir=/tmp/mytpm1 \
--ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock \
--tpm2 --log level=100
The command to start qemu is as follows:

This commit includes changes for the common code.
- Added support for the new checksum registers which are required for
the I2C support. The checksum calculation is handled in the qemu

- Added wrapper function for read and write data so that I2C code can

The TPM TIS I2C spec describes in the table in section "Interface Locality
Usage per Register" that the TPM_INT_ENABLE and TPM_INT_STATUS registers
must be writable for any locality even if the locality is not the active
locality. Therefore, remove the checks whether the writing locality is the
active locality for these registers.

The SOC on i.MX6UL and i.MX7 has 2 Ethernet interfaces. The PHY on each may
be connected to separate MDIO busses, or both may be connected on the same
MDIO bus using different PHY addresses. Commit 461c51ad42 ("Add a phy-num
property to the i.MX FEC emulator") added support for specifying PHY
addresses, but it did not provide support for linking the second PHY on
a given MDIO bus to the other Ethernet interface.
To be able to support two PHY instances on a single MDIO bus, two properties
are needed: First, there needs to be a flag indicating if the MDIO bus on
a given Ethernet interface is connected. If not, attempts to read from this
bus must always return 0xffff. Implement this property as phy-connected.
Second, if the MDIO bus on an interface is active, it needs a link to the
consumer interface to be able to provide PHY access for it. Implement this
property as phy-consumer.

be done at compile-time for target specific code, while it is done at

There should be no paths from a coroutine_fn to aio_poll, however in
practice coroutine_mixed_fn will call aio_poll in the !qemu_in_coroutine()
path. By marking mixed functions, we can track accurately the call paths
that execute entirely in coroutine context, and find more missing
coroutine_fn markers. This results in more accurate checks that
coroutine code does not end up blocking.
If the marking were extended transitively to all functions that call
these ones, static analysis could be done much more efficiently.
However, this is a start and makes it possible to use vrc's path-based
searches to find potential bugs where coroutine_fns call blocking functions.

Migrate rtc_ref (which only needs to be 32-bit because it is summed to
a 32-bit register), which requires bumping the migration version.
The HPPA machine does not have versioned machine types so it is okay
to block migration to old versions of QEMU.
While at it, drop the write-only field rtc from LasiState.

The introduction of the graph lock is causing blk_get_geometry, a hot function
used in the I/O path, to create a coroutine. However, the only part that really
needs to run in coroutine context is the call to bdrv_co_refresh_total_sectors,
which in turn only happens in the rare case of host CD-ROM devices.
So, write by hand the three wrappers on the path from blk_co_get_geometry to
bdrv_co_refresh_total_sectors, so that the coroutine wrapper is only created
if bdrv_nb_sectors actually calls bdrv_refresh_total_sectors.

At the protocol level, has_variable_length only needs to be true in the
very special case of host CD-ROM drives, so that they do not need an
explicit monitor command to read the new size when a disc is loaded
in the tray.
However, at the format level has_variable_length has to be true for all
raw blockdevs and for all filters, even though in practice the length
depends on the underlying file and thus will not change except in the
case of host CD-ROM drives.
As a first step towards computing an accurate value of has_variable_length,
add the value into the BlockLimits structure and initialize the field
from the BlockDriver.

blk_get_geometry() eventually calls bdrv_nb_sectors(), which is a
co_wrapper_mixed_bdrv_rdlock. This means that when it is called from
coroutine context, it already assume to have the graph locked.
However, virtio_blk_sect_range_ok() in block/export/virtio-blk-handler.c
(used by vhost-user-blk and VDUSE exports) runs in a coroutine, but
doesn't take the graph lock - blk_*() functions are generally expected
to do that internally. This causes an assertion failure when accessing
an export for the first time if it runs in an iothread.
This is an example of the crash:
$ ./storage-daemon/qemu-storage-daemon --object iothread,id=th0 --blockdev file,filename=/home/kwolf/images/hd.img,node-name=disk --export vhost-user-blk,addr.type=unix,addr.path=/tmp/vhost.sock,node-name=disk,id=exp0,iothread=th0

Fix this by creating a new blk_co_get_geometry() that takes the lock,
and changing blk_get_geometry() to be a co_wrapper_mixed around it.
To make the resulting code cleaner, virtio-blk-handler.c can directly
call the coroutine version now (though that wouldn't be necessary for
fixing the bug, taking the lock in blk_co_get_geometry() is what fixes
it).

Manually implement a socketpair() function, using UNIX sockets and
simple peer credential checking.
QEMU doesn't make much use of socketpair, beside vhost-user which is not
available for win32 at this point. However, I intend to use it for
writing some new portable tests.

Until now, a win32 SOCKET handle is often cast to an int file
descriptor, as this is what other OS use for sockets. When necessary,
QEMU eventually queries whether it's a socket with the help of
fd_is_socket(). However, there is no guarantee of conflict between the
fd and SOCKET space. Such conflict would have surprising consequences,
we shouldn't mix them.
Also, it is often forgotten that SOCKET must be closed with
closesocket(), and not close().
Instead, let's make the win32 socket wrapper functions return and take a
file descriptor, and let util/ wrappers do the fd/SOCKET conversion as
necessary. A bit of adaptation is necessary in io/ as well.
Unfortunately, we can't drop closesocket() usage, despite
_open_osfhandle() documentation claiming transfer of ownership, testing
shows bad behaviour if you forget to call closesocket().

Open-code the socket registration where it's needed, to avoid
artificially used or unclear generic interface.
Furthermore, the following patches are going to make socket handling use
FD-only inside QEMU, but we need to handle win32 SOCKET from libslirp.

igb, a new network device emulation, will need SCTP checksum offloading.
Currently eth_get_protocols() has a bool parameter for each protocol
currently it supports, but there will be a bit too many parameters if
we add yet another protocol.
Introduce an enum type, EthL4HdrProto to represent all L4 protocols

The values returned by eth_get_protocols() are used to perform RSS,
checksumming and segmentation. Even when a packet signals the use of the
protocols which these operations can be applied to, the headers for them
may not be present because of too short packet or fragmentation, for
example. In such a case, the operations cannot be applied safely.
Report the presence of headers instead of whether the use of the
protocols are indicated with eth_get_protocols(). This also makes
corresponding changes to the callers of eth_get_protocols() to match
with its new signature and to remove redundant checks for fragmentation.

There was no proper implementation of TCP segmentation before this
change, and net_tx_pkt relied solely on IPv4 fragmentation. Not only
this is not aligned with the specification, but it also resulted in
corrupted IPv6 packets.
This is particularly problematic for the igb, a new proposed device
implementation; igb provides loopback feature for VMDq and the feature
relies on software segmentation.
Implement proper TCP segmentation in net_tx_pkt to fix such a scenario.

The CXL r3.0 specification allows for there to be no HDM decoders on CXL
Host Bridges if they have only a single root port. Instead, all accesses
directed to the host bridge (as specified in CXL Fixed Memory Windows)
are assumed to be routed to the single root port.
Linux currently assumes this implementation choice. So to simplify testing,
make QEMU emulation also default to no HDM decoders under these particular
circumstances, but provide a hdm_for_passthrough boolean option to have
HDM decoders as previously.
Technically this is breaking backwards compatibility, but given the only
known software stack used with the QEMU emulation is the Linux kernel
and this configuration did not work before this change, there are
unlikely to be any complaints that it now works. The option is retained
to allow testing of software that does allow for these HDM decoders to exist,
once someone writes it.

Back in the mists of time, before EISA came along and required per-pin
level control in the ELCR register, the i8259 had a single chip-wide
level-mode control in bit 3 of ICW1.
Even in the PIIX3 datasheet from 1996 this is documented as 'This bit is
disabled', but apparently MorphOS is using it in the version of the
i8259 which is in the Pegasos2 board as part of the VT8231 chipset.
It's easy enough to implement, and I think it's harmless enough to do so
unconditionally.

QOM objects shouldn't access each other internals fields
except using the QOM API.
mips_cps_realize() instantiates a TYPE_MIPS_ITU object, and
directly sets the 'saar' pointer:
if (saar_present) {
s->itu.saar = &env->CP0_SAAR;
}
In order to avoid that, pass the MIPS_CPU object via a QOM
link property, and set the 'saar' pointer in mips_itu_realize().

CXL uses PCI AER Internal errors to signal to the host that an error has
occurred. The host can then read more detailed status from the CXL RAS
capability.
For uncorrectable errors: support multiple injection in one operation
as this is needed to reliably test multiple header logging support in an
OS. The equivalent feature doesn't exist for correctable errors, so only
one error need be injected at a time.
Note:
- Header content needs to be manually specified in a fashion that
matches the specification for what can be in the header for each
error type.

Currently the property may flip its state
during VM bring up or just doesn't work as
the name implies.
In particular with PCIE root port that has
'hotplug={on|off}' property, and when it's
turned off, one would expect
'hotpluggable' == false
for any devices attached to it.
Which is not the case since qbus_is_hotpluggable()
used by the property just checks for presence
of any hotplug_handler set on bus.
The problem is that name BusState::hotplug_handler
from its inception is misnomer, as it handles
not only hotplug but also in many cases coldplug
as well (i.e. generic wiring interface), and
it's fine to have hotplug_handler set on bus
while it doesn't support hotplug (ex. pcie-slot
with hotplug=off).
Another case of root port flipping 'hotpluggable'
state when ACPI PCI hotplug is enabled in this
case root port with 'hotplug=off' starts as
hotpluggable and then later on, pcihp
hotplug_handler clears hotplug_handler
explicitly after checking root port's 'hotplug'
property.
So root-port hotpluggablity check sort of works
if pcihp is enabled but is broken if pcihp is
disabled.
One way to deal with the issue is to ask
hotplug_handler if bus it controls is hotpluggable
or not. To do that add is_hotpluggable_bus()
hook to HotplugHandler interface and use it in
'hotpluggable' property + teach pcie-slot to
actually look into 'hotplug' property state
before deciding if bus is hotpluggable.

Migrating with vIOMMU will require either tracking maximum
IOMMU supported address space (e.g. 39/48 address width on Intel)
or range-track current mappings and dirty track the new ones
post starting dirty tracking. This will be done as a separate
series, so add a live migration blocker until that is fixed.

Add device dirty page tracking start/stop functionality. This uses the
device DMA logging uAPI to start and stop dirty page tracking by device.
Device dirty page tracking is used only if all devices within a
container support device dirty page tracking.

This aids subsystems (like gdbstub) that want to trigger a flush
without pulling target specific headers.

Prototypes using gdb_syscall_complete_cb() or gdb_?et_reg_cb()
don't depend on "cpu.h", thus are not target-specific.

This header is now only for native Xen code, not PV backends that may be
used in Xen emulation. Since the toolstack libraries may depend on the
specific version of Xen headers that they pull in (and will set the
__XEN_TOOLS__ macro to enable internal definitions that they depend on),
the rule is that xen_native.h (and thus the toolstack library headers)
must be included *before* any of the headers in include/hw/xen/interface.
