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.

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.

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.

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

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.
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
common code.
- Added wrapper function for read and write data so that I2C code can
call it without MMIO interface.
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.

Both sun4i and sun6i variants are supported.
However, interrupt generation is not supported, so WDT can be used only to trigger system reset.

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.

CPU watchpoints can be use by non-TCG accelerators.
KVM uses them:
$ git grep CPUWatchpoint|fgrep kvm
target/arm/kvm64.c:1558: CPUWatchpoint *wp = find_hw_watchpoint(cs, debug_exit->far);
target/i386/kvm/kvm.c:5216:static CPUWatchpoint hw_watchpoint;
target/ppc/kvm.c:443:static CPUWatchpoint hw_watchpoint;
target/s390x/kvm/kvm.c:139:static CPUWatchpoint hw_watchpoint;
See for example commit e4482ab7e3 ("target-arm: kvm - add support
for HW assisted debug"):
This adds basic support for HW assisted debug. The ioctl interface
to KVM allows us to pass an implementation defined number of break
and watch point registers. [...]

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.

These two helpers enable host bridges to operate differently depending on
the number of downstream ports, in particular if there is only a single

Useful for CXL where HDM address decoders are allowed to be implicit in

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

mips_cps_realize() instantiates a TYPE_MIPS_ITU object, and
directly sets the 'saar' pointer:
if (saar_present) {

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.

The previous commit introduced redirectable gnttab operations fairly
much like-for-like, with the exception of the extra arguments to the
->open() call which were always NULL/0 anyway.
This *changes* the arguments to the ->unmap() operation to include the
original ref# that was mapped. Under real Xen it isn't necessary; all we
need to do from QEMU is munmap(), then the kernel will release the grant,
and Xen does the tracking/refcounting for the guest.
When we have emulated grant tables though, we need to do all that for
ourselves. So let's have the back ends keep track of what they mapped
and pass it in to the ->unmap() method for us.

Move the existing code using libxengnttab to xen-operations.c and allow
the operations to be redirected so that we can add emulation of grant
table mapping for backend drivers.
In emulation, mapping more than one grant ref to be virtually contiguous
would be fairly difficult. The best way to do it might be to make the
ram_block mappings actually backed by a file (shmem or a deleted file,
perhaps) so that we can have multiple *shared* mappings of it. But that
would be fairly intrusive.
Making the backend drivers cope with page *lists* instead of expecting
the mapping to be contiguous is also non-trivial, since some structures
would actually *cross* page boundaries (e.g. the 32-bit blkif responses
which are 12 bytes).
So for now, we'll support only single-page mappings in emulation. Add a
XEN_GNTTAB_OP_FEATURE_MAP_MULTIPLE flag to indicate that the native Xen
implementation *does* support multi-page maps, and a helper function to
query it.

Fedora 39 will ship its arm64 kernels in the new generic EFI zboot
format, using gzip compression for the payload.
For doing EFI boot in QEMU, this is completely transparent, as the
firmware or bootloader will take care of this. However, for direct
kernel boot without firmware, we will lose the ability to boot such
distro kernels unless we deal with the new format directly.
EFI zboot images contain metadata in the header regarding the placement
of the compressed payload inside the image, and the type of compression
used. This means we can wire up the existing gzip support without too
much hassle, by parsing the header and grabbing the payload from inside
the loaded zboot image.

pnv_phb4_pec: Simplify/align code to parent user-created PHBs
pnv_phb4_pec: Move pnv_phb4_get_pec() to rightful file
pnv_phb4_pec: Only export existing PHBs to the device tree

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
When instantiating a user-created PHB on P9/P10, we don't really have
a reason any more to go through an indirection in pnv_chip_add_phb()
in pnv.c, we can go straight to the right function in
pnv_phb4_pec.c. That way, default PHBs and user-created PHBs are all
handled in the same file. This patch also renames pnv_phb4_get_pec()
to pnv_pec_add_phb() to better reflect that it "hooks" a PHB to a PEC.
For P8, the PHBs are parented to the chip directly, so it makes sense
to keep calling pnv_chip_add_phb() in pnv.c, to also be consistent
with where default PHBs are handled. The only change here is that,
since that function is now only used for P8, we can refine the return
type.
So overall, the PnvPHB front-end now has a pnv_phb_user_get_parent()
function which handles the parenting of the user-created PHBs by
calling the right function in the right file based on the processor
version. It's also easily extensible if we ever need to support a
different parent object.

The function pnv_phb4_get_pec() exposes some internals of the PEC and
PHB logic, yet it was in the higher level hw/ppc/pnv.c file for
historical reasons: P8 implements the PHBs from pnv.c directly, but on
P9/P10, it's done through the CEC model, which has its own file. So
move pnv_phb4_get_pec() to hw/pci-host/pnv_phb4_pec.c, where it fits
naturally.
While at it, replace the PnvPHB4 parameter by the PnvPHB front-end,
since it has all the information needed and simplify it a bit.
No functional changes.

Add an array on the PEC object to keep track of the PHBs which are
instantiated. The array can be sparsely populated when using
user-created PHBs. It will be useful for the next patch to only export
instantiated PHBs in the device tree.

In theory gsi base can start from 0 on loongarch virt machine,
however gsi base is hard-coded in linux kernel loongarch system,
else system fails to boot.
This patch renames macro PCH_PIC_IRQ_OFFSET with VIRT_GSI_BASE,
keeps value unchanged. GSI base is common concept in acpi spec
and easy to understand.

Use the new network order initializer for cel_uuid. Adjust
cxl_initialize_mailbox() because it can't fail now.

The default boot address of the Aspeed SoCs is 0x0. For this reason,
the FMC flash device contents are remapped by HW on the first 256MB of
the address space. In QEMU, this is currently done in the machine init
with the setup of a region alias.
Move this code to the SoC and introduce an extra container to prepare
ground for the boot ROM region which will overlap the FMC flash
remapping.

vhost_dev_cleanup(), called from vu_gpio_disconnect(), clears vhost_dev
so vhost-user-gpio must set the members of vhost_dev each time
connecting.
do_vhost_user_cleanup() should also acquire the pointer to vqs directly
from VHostUserGPIO instead of referring to vhost_dev as it can be called
after vhost_dev_cleanup().

The way that Xen handles MSI PIRQs is kind of awful.
There is a special MSI message which targets a PIRQ. The vector in the
low bits of data must be zero. The low 8 bits of the PIRQ# are in the
destination ID field, the extended destination ID field is unused, and
instead the high bits of the PIRQ# are in the high 32 bits of the address.
Using the high bits of the address means that we can't intercept and
translate these messages in kvm_send_msi(), because they won't be caught
by the APIC — addresses like 0x1000fee46000 aren't in the APIC's range.
So we catch them in pci_msi_trigger() instead, and deliver the event
channel directly.
That isn't even the worst part. The worst part is that Xen snoops on
writes to devices' MSI vectors while they are *masked*. When a MSI
message is written which looks like it targets a PIRQ, it remembers
the device and vector for later.
When the guest makes a hypercall to bind that PIRQ# (snooped from a
marked MSI vector) to an event channel port, Xen *unmasks* that MSI
vector on the device. Xen guests using PIRQ delivery of MSI don't
ever actually unmask the MSI for themselves.
Now that this is working we can finally enable XENFEAT_hvm_pirqs and
let the guest use it all.
Tested with passthrough igb and emulated e1000e + AHCI.

There's already a partial set here; update them and pull in a more
complete set.
To start with, define __XEN_TOOLS__ in hw/xen/xen.h to ensure that any
internal definitions needed by Xen toolstack libraries are present
regardless of the order in which the headers are included. A reckoning
will come later, once we make the PV backends work in emulation and
untangle the headers for Xen-native vs. generic parts.
