934676c7b7 ppc/pnv: SMT support for powernv
Set the TIR default value with the SMT thread index, and place some
standard limits on SMT configurations. Now powernv is able to boot
skiboot and Linux with a SMT topology, including booting a KVM guest.

There are several SPRs and other features (e.g., broadcast msgsnd)
that are not implemented, but not used by OPAL or Linux and can be
added incrementally.

3401ea3cfe target/ppc: Add LPAR-per-core vs per-thread mode flag
The Power ISA has the concept of sub-processors:

  Hardware is allowed to sub-divide a multi-threaded processor into
  "sub-processors" that appear to privileged programs as multi-threaded
  processors with fewer threads.

POWER9 and POWER10 have two modes, either every thread is a
sub-processor or all threads appear as one multi-threaded processor. In
the user manuals these are known as "LPAR per thread" / "Thread LPAR",
and "LPAR per core" / "1 LPAR", respectively.

The practical difference is: in thread LPAR mode, non-hypervisor SPRs
are not shared between threads and msgsndp can not be used to message
siblings. In 1 LPAR mode, some SPRs are shared and msgsndp is usable.
Thrad LPAR allows multiple partitions to run concurrently on the same
core, and is a requirement for KVM to run on POWER9/10 (which does not
gang-schedule an LPAR on all threads of a core like POWER8 KVM).

Traditionally, SMT in PAPR environments including PowerVM and the
pseries QEMU machine with KVM acceleration behaves as in 1 LPAR mode.
In OPAL systems, Thread LPAR is used. When adding SMT to the powernv
machine, it is therefore preferable to emulate Thread LPAR.

To account for this difference between pseries and powernv, an LPAR mode
flag is added such that SPRs can be implemented as per-LPAR shared, and
that becomes either per-thread or per-core depending on the flag.

ed75a12357 pnv/xive2: Always pass a presenter object when accessing the TIMA
The low-level functions to access the TIMA take a presenter object as
a first argument. When accessing the TIMA from the IC BAR,
i.e. indirect calls, we currently pass a NULL pointer for the
presenter argument. While it appears ok with the current usage, it's
dangerous. And it's pretty easy to figure out the presenter in that
context, so this patch fixes it.

694d3cb2ef pnv/xive2: Fix TIMA offset for indirect access
Direct TIMA operations can be done through 4 pages, each with a
different privilege level dictating what fields can be accessed. On
the other hand, indirect TIMA accesses on P10 are done through a
single page, which is the equivalent of the most privileged page of
direct TIMA accesses.

The offset in the IC bar of an indirect access specifies what hw
thread is targeted (page shift bits) and the offset in the
TIMA being accessed (the page offset bits). When the indirect
access is calling the underlying direct access functions, it is
therefore important to clearly separate the 2, as the direct functions
assume any page shift bits define the privilege ring level. For
indirect accesses, those bits must be 0. This patch fixes the offset
passed to direct TIMA functions.

It didn't matter for SMT1, as the 2 least significant bits of the page
shift are part of the hw thread ID and always 0, so the direct TIMA
functions were accessing the privilege ring 0 page. With SMT4/8, it is
no longer true.

The fix is specific to P10, as indirect TIMA access on P9 was handled
differently.

d73a175150 pnv/xive2: Allow indirect TIMA accesses of all sizes
Booting linux on the powernv10 machine logs a few errors like:

Invalid read at addr 0x38, size 1, region 'xive-ic-tm-indirect', reason: invalid size (min:8 max:8)
Invalid write at addr 0x38, size 1, region 'xive-ic-tm-indirect', reason: invalid size (min:8 max:8)
Invalid read at addr 0x38, size 1, region 'xive-ic-tm-indirect', reason: invalid size (min:8 max:8)

Those errors happen when linux is resetting XIVE. We're trying to
read/write the enablement bit for the hardware context and qemu
doesn't allow indirect TIMA accesses of less than 8 bytes. Direct TIMA
access can go through though, as well as indirect TIMA accesses on P9.
So even though there are some restrictions regarding the address/size
combinations for TIMA access, the example above is perfectly valid.

This patch lets indirect TIMA accesses of all sizes go through. The
special operations will be intercepted and the default "raw" handlers
will pick up all other requests and complain about invalid sizes as
appropriate.

2ad2e113de hw/ppc: Fix clock update drift
The clock update logic reads the clock twice to compute the new clock
value, with a value derived from the later time subtracted from a value
derived from the earlier time. The delta causes time to be lost.

This can ultimately result in time becoming unsynchronized between CPUs
and that can cause OS lockups, timeouts, watchdogs, etc. This can be
seen running a KVM guest (that causes lots of TB updates) on a powernv
SMP machine.

Fix this by reading the clock once.

71d72ececa 9pfs: deprecate 'proxy' backend
As recent CVE-2023-2861 (fixed by f6b0de53fb) once again showed, the 9p
'proxy' fs driver is in bad shape. Using the 'proxy' backend was already
discouraged for safety reasons before and we recommended to use the
'local' backend (preferably in conjunction with its 'mapped' security
model) instead, but now it is time to officially deprecate the 'proxy'
backend.

62c2b8760b hw/arm/sbsa-ref: use XHCI to replace EHCI
The current sbsa-ref cannot use EHCI controller which is only
able to do 32-bit DMA, since sbsa-ref doesn't have RAM below 4GB.
Hence, this uses XHCI to provide a usb controller with 64-bit
DMA capablity instead of EHCI.

We bump the platform version to 0.3 with this change.  Although the
hardware at the USB controller address changes, the firmware and
Linux can both cope with this -- on an older non-XHCI-aware
firmware/kernel setup the probe routine simply fails and the guest
proceeds without any USB.  (This isn't a loss of functionality,
because the old USB controller never worked in the first place.) So
we can call this a backwards-compatible change and only bump the
minor version.

357bd7932a vfio/pci: Fix a segfault in vfio_realize
The kvm irqchip notifier is only registered if the device supports
INTx, however it's unconditionally removed in vfio realize error
path. If the assigned device does not support INTx, this will cause
QEMU to crash when vfio realize fails. Change it to conditionally
remove the notifier only if the notify hook is setup.

Before fix:

Connection closed by foreign host.

After fix:

8bbcb64a71 vfio/migration: Make VFIO migration non-experimental
The major parts of VFIO migration are supported today in QEMU. This
includes basic VFIO migration, device dirty page tracking and precopy
support.

Thus, at this point in time, it seems appropriate to make VFIO migration
non-experimental: remove the x prefix from enable_migration property,
change it to ON_OFF_AUTO and let the default value be AUTO.

In addition, make the following adjustments:
1. When enable_migration is ON and migration is not supported, fail VFIO
   device realization.
2. When enable_migration is AUTO (i.e., not explicitly enabled), require
   device dirty tracking support. This is because device dirty tracking
   is currently the only method to do dirty page tracking, which is
   essential for migrating in a reasonable downtime. Setting
   enable_migration to ON will not require device dirty tracking.
3. Make migration error and blocker messages more elaborate.
4. Remove error prints in vfio_migration_query_flags().
5. Rename trace_vfio_migration_probe() to
   trace_vfio_migration_realize().

808642a2f6 vfio/migration: Reset bytes_transferred properly
Currently, VFIO bytes_transferred is not reset properly:
1. bytes_transferred is not reset after a VM snapshot (so a migration
   following a snapshot will report incorrect value).
2. bytes_transferred is a single counter for all VFIO devices, however
   upon migration failure it is reset multiple times, by each VFIO
   device.

Fix it by introducing a new function vfio_reset_bytes_transferred() and
calling it during migration and snapshot start.

Remove existing bytes_transferred reset in VFIO migration state
notifier, which is not needed anymore.

745c42912a vfio/migration: Add support for switchover ack capability
Loading of a VFIO device's data can take a substantial amount of time as
the device may need to allocate resources, prepare internal data
structures, etc. This can increase migration downtime, especially for
VFIO devices with a lot of resources.

To solve this, VFIO migration uAPI defines "initial bytes" as part of
its precopy data stream. Initial bytes can be used in various ways to
improve VFIO migration performance. For example, it can be used to
transfer device metadata to pre-allocate resources in the destination.
However, for this to work we need to make sure that all initial bytes
are sent and loaded in the destination before the source VM is stopped.

Use migration switchover ack capability to make sure a VFIO device's
initial bytes are sent and loaded in the destination before the source
stops the VM and attempts to complete the migration.
This can significantly reduce migration downtime for some devices.

eda7362af9 vfio/migration: Add VFIO migration pre-copy support
Pre-copy support allows the VFIO device data to be transferred while the
VM is running. This helps to accommodate VFIO devices that have a large
amount of data that needs to be transferred, and it can reduce migration
downtime.

Pre-copy support is optional in VFIO migration protocol v2.
Implement pre-copy of VFIO migration protocol v2 and use it for devices
that support it. Full description of it can be found in the following
Linux commit: 4db52602a607 ("vfio: Extend the device migration protocol

ca3fcdeeee net/vhost-net: do not assert on null pointer return from tap_get_vhost_net()
When 'vhost=off' or no vhost specific options at all are passed for the tap
net-device backend, tap_get_vhost_net() can return NULL. The function
net_init_tap_one() does not call vhost_net_init() on such cases and therefore
vhost_net pointer within the tap device state structure remains NULL. Hence,
assertion here on a NULL pointer return from tap_get_vhost_net() would not be
correct. Remove it and fix the crash generated by qemu upon initialization in
the following call chain :

qdev_realize() -> pci_qdev_realize() -> virtio_device_realize() ->
virtio_bus_device_plugged() -> virtio_net_get_features() -> get_vhost_net()

6b90a4cdc0 escc: emulate dip switch language layout settings on SUN keyboard
SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
and uses that value to select keyboard layout.  Also the SUN bios like the one
in the file ss5.bin uses this value to support at least some keyboard layouts.
However, the OpenBIOS provided with qemu is hardcoded to always use an US
keyboard layout.

Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
this patch uses a command line switch like
"-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
used to lookup values from arguments like:

-global escc.chnA-sunkbd-layout=fr
-global escc.chnA-sunkbd-layout=es

But the patch also accepts numeric dip switch values directly:

-global escc.chnA-sunkbd-layout=0x2b
-global escc.chnA-sunkbd-layout=43

Both values above are the same and select swedish keyboard as explained in
table 3-15 at
https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html

Unless you want to do a full Solaris installation but happen to have
access to a Sun bios file, the easiest way to test that the patch works
is to:

qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin

If you already happen to have a Solaris installation in a qemu disk image
file you can easily try different keyboard layouts after this patch is
applied.

ec4d71e8f2 virtio-gpu-udmabuf: create udmabuf for blob even when iov_cnt == 1
There were often cases where a scanout blob sometimes has just 1 entry
that is linked to many pages in it. So just checking whether iov_cnt is 1
is not enough for screening small, non-scanout blobs. Therefore adding
iov_len check as well to make sure it creates an udmabuf only for a scanout
blob, which is at least bigger than one page size.

ebe1504e10 intel_iommu: Fix address space unmap
During address space unmap, corresponding IOVA tree entries are
also removed. But DMAMap is set beyond notifier's scope by 1, so
in theory there is possibility to remove a continuous entry above
the notifier's scope but falling in adjacent notifier's scope.

There is no issue currently as no use cases allocate notifiers
continuously, but let's be robust.

e80c1e4c7d intel_iommu: Fix a potential issue in VFIO dirty page sync
Peter Xu found a potential issue:

"The other thing is when I am looking at the new code I found that we
actually extended the replay() to be used also in dirty tracking of vfio,
in vfio_sync_dirty_bitmap().  For that maybe it's already broken if
unmap_all() because afaiu log_sync() can be called in migration thread
anytime during DMA so I think it means the device is prone to DMA with the
IOMMU pgtable quickly erased and rebuilt here, which means the DMA could
fail unexpectedly.  Copy Alex, Kirti and Neo."

Fix it by replacing the unmap_all() to only evacuate the iova tree
(keeping all host mappings untouched, IOW, don't notify UNMAP), and
do a full resync in page walk which will notify all existing mappings
as MAP. This way we don't interrupt with any existing mapping if there
is (e.g. for the dirty sync case), meanwhile we keep sync too to latest
(for moving a vfio device into an existing iommu group).

535a3d9a32 virtio-scsi: avoid dangling host notifier in ->ioeventfd_stop()
virtio_scsi_dataplane_stop() calls blk_drain_all(), which invokes
->drained_begin()/->drained_end() after we've already detached the host
notifier. virtio_scsi_drained_end() currently attaches the host notifier
again and leaves it dangling after dataplane has stopped.

This results in the following assertion failure because
virtio_scsi_defer_to_dataplane() is called from the IOThread instead of
the main loop thread:

0b545b1e42 virtio-net: expose virtio_net_supported_guest_offloads()
To support restoring offloads state in vdpa, it is necessary to
expose the function virtio_net_supported_guest_offloads().

According to VirtIO standard, "Upon feature negotiation
corresponding offload gets enabled to preserve backward compatibility.".
Therefore, QEMU uses this function to get the device supported offloads.
This allows QEMU to know the device's defaults and skip the control
message sending if these defaults align with the driver's configuration.

Note that the device's defaults can mismatch the driver's configuration
only at live migration.

addr 0 instead. Remove the acpi_pm1_cnt_write() function which is used
only once and does not take addr into account and handle non-zero
address in acpi_pm_cnt_{read|write}. This fixes ACPI shutdown with
pegasos2 firmware.

The issue below is possibly related to the same memory core bug.

177835304b pnv/xive2: Check TIMA special ops against a dedicated array for P10
Accessing the TIMA from some specific ring/offset combination can
trigger a special operation, with or without side effects. It is
implemented in qemu with an array of special operations to compare
accesses against. Since the presenter on P10 is pretty similar to P9,
we had the full array defined for P9 and we just had a special case
for P10 to treat one access differently. With a recent change,
6f2cbd133d ("pnv/xive2: Handle TIMA access through all ports"), we
now ignore some of the bits of the TIMA address, but that patch
managed to botch the detection of the special case for P10.

To clean that up, this patch introduces a full array of special ops to
be used for P10. The code to detect a special access is common with
P9, only the array of operations differs. The presenter can pick the
correct array of special ops based on its configuration introduced in
a previous patch.

dc5e072188 spapr: TCG allow up to 8-thread SMT on POWER8 and newer CPUs
PPC TCG supports SMT CPU configurations for non-hypervisor state, so
permit POWER8-10 pseries machines to enable SMT.

This requires PIR and TIR be set, because that's how sibling thread
matching is done by TCG.

spapr's nested-HV capability does not currently coexist with SMT, so
that combination is prohibited (interestingly somewhat analogous to
LPAR-per-core mode on real hardware which also does not support KVM).

also eases code review, because here we don't care about
KVM, we really want to test for TCG.

50ba97e928 target/hppa: Fix OS reboot issues
When the OS triggers a reboot, the reset helper function sends a
qemu_system_reset_request(SHUTDOWN_CAUSE_GUEST_RESET) together with an
EXCP_HLT exception to halt the CPUs.

So, at reboot when initializing the CPUs again, make sure to set all
instruction pointers to the firmware entry point, disable any interrupts,
disable data and instruction translations, enable PSW_Q bit  and tell qemu
to unhalt (halted=0) the CPUs again.

This fixes the various reboot issues which were seen when rebooting a
Linux VM, including the case where even the monarch CPU has been virtually
halted from the OS (e.g. via "chcpu -d 0" inside the Linux VM).

8eb85fb5ac pci: ROM preallocation for incoming migration
On incoming migration we have the following sequence to load option
ROM:

1. On device realize we do normal load ROM from the file

2. Than, on incoming migration we rewrite ROM from the incoming RAM
   block. If sizes mismatch we fail, like this:

    Size mismatch: 0000:00:03.0/virtio-net-pci.rom: 0x40000 != 0x80000: Invalid argument

This is not ideal when we migrate to updated distribution: we have to
keep old ROM files in new distribution and be careful around romfile
property to load correct ROM file. Which is loaded actually just to
allocate the ROM with correct length.

Note, that romsize property doesn't really help: if we try to specify
it when default romfile is larger, it fails with something like:

    romfile "efi-virtio.rom" (160768 bytes) is too large for ROM size 65536

Let's just ignore ROM file when romsize is specified and we are in
incoming migration state. In other words, we need only to preallocate
ROM of specified size, local ROM file is unrelated.

This way:

If romsize was specified on source, we just use same commandline as on
source, and migration will work independently of local ROM files on
target.

If romsize was not specified on source (and we have mismatching local
ROM file on target host), we have to specify romsize on target to match
source romsize. romfile parameter may be kept same as on source or may
be dropped, the file is not loaded anyway.

As a bonus we avoid extra reading from ROM file on target.

Note: when we don't have romsize parameter on source command line and
need it for target, it may be calculated as aligned up to power of two
size of ROM file on source (if we know, which file is it) or,
alternatively it may be retrieved from source QEMU by QMP qom-get
command, like

  { "execute": "qom-get",
    "arguments": {
      "path": "/machine/peripheral/CARD_ID/virtio-net-pci.rom[0]",
      "property": "size" } }

Note: we have extra initialization of size variable to zero in
      pci_add_option_rom to avoid false-positive
      "error: ‘size’ may be used uninitialized"

bafe030832 hw/cxl/events: Add injection of Memory Module Events
These events include a copy of the device health information at the
time of the event. Actually using the emulated device health would
require a lot of controls to manipulate that state.  Given the aim
of this injection code is to just test the flows when events occur,
inject the contents of the device health state as well.

Future work may add more sophisticate device health emulation
including direct generation of these records when events occur
(such as a temperature threshold being crossed).  That does not
reduce the usefulness of this more basic generation of the events.

Inject poison using QMP command cxl-inject-poison to add an entry to the

For now, the poison is not returned CXL.mem reads, but only via the
mailbox command Get Poison List. So a normal memory read to an address
that is on the poison list will not yet result in a synchronous exception
(and similar for partial cacheline writes).
That is left for a future patch.

See CXL rev 3.0, sec 8.2.9.8.4.1 Get Poison list (Opcode 4300h)

Kernel patches to use this interface here:
https://lore.kernel.org/linux-cxl/cover.1665606782.git.alison.schofield@intel.com/

To inject poison using QMP (telnet to the QMP port)
{ "execute": "qmp_capabilities" }

{ "execute": "cxl-inject-poison",

    }
}

Adjusted to select a device on your machine.

Note that the poison list supported is kept short enough to avoid the

532009054b mac_via: fix rtc command decoding for the PRAM seconds registers
Analysis of the MacOS toolbox ROM code shows that on startup it attempts 2
separate reads of the seconds registers with commands 0x9d...0x91 followed by
0x8d..0x81 without resetting the command to its initial value. The PRAM seconds
value is only accepted when the values of the 2 separate reads match.

From this we conclude that bit 4 of the rtc command is not decoded or we don't
care about its value when reading the PRAM seconds registers. Implement this
decoding change so that both reads return successfully which allows the MacOS
toolbox ROM to correctly set the date/time.

f18a288632 q800: reimplement mac-io region aliasing using IO memory region
The current use of aliased memory regions causes us 2 problems: firstly the
output of "info qom-tree" is absolutely huge and difficult to read, and
secondly we have already reached the internal limit for memory regions as
adding any new memory region into the mac-io region causes QEMU to assert
with "phys_section_add: Assertion `map->sections_nb < TARGET_PAGE_SIZE'
failed".

Implement the mac-io region aliasing using a single IO memory region that
applies IO_SLICE_MASK representing the maximum size of the aliased region and
then forwarding the access to the existing mac-io memory region using the
address space API.

bd96e10071 imx_serial: set wake bit when we receive a data byte
The Linux kernel added a flood check for RX data recently in commit
496a4471b7c3 ("serial: imx: work-around for hardware RX flood"). This
check uses the wake bit in the UART status register 2. The wake bit
indicates that the receiver detected a start bit on the RX line. If the
kernel sees a number of RX interrupts without the wake bit being set, it
treats this as spurious data and resets the UART port. imx_serial does
never set the wake bit and triggers the kernel's flood check.

This patch adds support for the wake bit. wake is set when we receive a
new character (it's not set for break events). It seems that wake is
cleared by the kernel driver, the hardware does not have to clear it
automatically after data was read.

The wake bit can be configured as an interrupt source. Support this
mechanism as well.

d2f9a79a8c hw/timer/nrf51_timer: Don't lose time when timer is queried in tight loop
The nrf51_timer has a free-running counter which we implement using
the pattern of using two fields (update_counter_ns, counter) to track
the last point at which we calculated the counter value, and the
counter value at that time.  Then we can find the current counter
value by converting the difference in wall-clock time between then
and now to a tick count that we need to add to the counter value.

Unfortunately the nrf51_timer's implementation of this has a bug
which means it loses time every time update_counter() is called.
After updating s->counter it always sets s->update_counter_ns to
'now', even though the actual point when s->counter hit the new value
will be some point in the past (half a tick, say).  In the worst case
(guest code in a tight loop reading the counter, icount mode) the
counter is continually queried less than a tick after it was last
read, so s->counter never advances but s->update_counter_ns does, and
the guest never makes forward progress.

The fix for this is to only advance update_counter_ns to the
timestamp of the last tick, not all the way to 'now'.  (This is the
pattern used in hw/misc/mps2-fpgaio.c's counter.)

22c81783c9 hw/sd/allwinner-sdhost: Don't send non-boolean IRQ line levels
QEMU allows qemu_irq lines to transfer arbitrary integers.  However
the convention is that for a simple IRQ line the values transferred
are always 0 and 1.  The A10 SD controller device instead assumes a
0-vs-non-0 convention, which happens to work with the interrupt

f837b468cd hw/intc/allwinner-a10-pic: Handle IRQ levels other than 0 or 1
In commit 2c5fa0778c we fixed an endianness bug in the Allwinner
A10 PIC model; however in the process we introduced a regression.
This is because the old code was robust against the incoming 'level'
argument being something other than 0 or 1, whereas the new code was
not.

In particular, the allwinner-sdhost code treats its IRQ line
as 0-vs-non-0 rather than 0-vs-1, so when the SD controller
set its IRQ line for any reason other than transmit the
interrupt controller would ignore it. The observed effect
was a guest timeout when rebooting the guest kernel.

Handle level values other than 0 or 1, to restore the old
behaviour.

Fixes: 2c5fa0778c ("hw/intc/allwinner-a10-pic: Don't use set_bit()/clear_bit()")

733766cd37 hw/arm: introduce xenpvh machine
Add a new machine xenpvh which creates a IOREQ server to register/connect with
Xen Hypervisor.

Optional: When CONFIG_TPM is enabled, it also creates a tpm-tis-device, adds a
TPM emulator and connects to swtpm running on host machine via chardev socket
and support TPM functionalities for a guest domain.

Extra command line for aarch64 xenpvh QEMU to connect to swtpm:
    -chardev socket,id=chrtpm,path=/tmp/myvtpm2/swtpm-sock \
    -tpmdev emulator,id=tpm0,chardev=chrtpm \
    -machine tpm-base-addr=0x0c000000 \

swtpm implements a TPM software emulator(TPM 1.2 & TPM 2) built on libtpms and
provides access to TPM functionality over socket, chardev and CUSE interface.
Github repo: https://github.com/stefanberger/swtpm
Example for starting swtpm on host machine:
    mkdir /tmp/vtpm2
    swtpm socket --tpmstate dir=/tmp/vtpm2 \
    --ctrl type=unixio,path=/tmp/vtpm2/swtpm-sock &

f17068c1c7 xen-hvm: reorganize xen-hvm and move common function to xen-hvm-common
This patch does following:
1. creates arch_handle_ioreq() and arch_xen_set_memory(). This is done in
    preparation for moving most of xen-hvm code to an arch-neutral location,
    move the x86-specific portion of xen_set_memory to arch_xen_set_memory.
    Also, move handle_vmport_ioreq to arch_handle_ioreq.

2. Pure code movement: move common functions to hw/xen/xen-hvm-common.c
    Extract common functionalities from hw/i386/xen/xen-hvm.c and move them to
    hw/xen/xen-hvm-common.c. These common functions are useful for creating
    an IOREQ server.

    xen_hvm_init_pc() contains the architecture independent code for creating
    and mapping a IOREQ server, connecting memory and IO listeners, initializing
    a xen bus and registering backends. Moved this common xen code to a new
    function xen_register_ioreq() which can be used by both x86 and ARM machines.

    Following functions are moved to hw/xen/xen-hvm-common.c:
        xen_vcpu_eport(), xen_vcpu_ioreq(), xen_ram_alloc(), xen_set_memory(),
        xen_region_add(), xen_region_del(), xen_io_add(), xen_io_del(),
        xen_device_realize(), xen_device_unrealize(),
        cpu_get_ioreq_from_shared_memory(), cpu_get_ioreq(), do_inp(),
        do_outp(), rw_phys_req_item(), read_phys_req_item(),
        write_phys_req_item(), cpu_ioreq_pio(), cpu_ioreq_move(),
        cpu_ioreq_config(), handle_ioreq(), handle_buffered_iopage(),
        handle_buffered_io(), cpu_handle_ioreq(), xen_main_loop_prepare(),
        xen_hvm_change_state_handler(), xen_exit_notifier(),
        xen_map_ioreq_server(), destroy_hvm_domain() and
        xen_shutdown_fatal_error()

3. Removed static type from below functions:
    1. xen_region_add()
    2. xen_region_del()
    3. xen_io_add()
    4. xen_io_del()
    5. xen_device_realize()
    6. xen_device_unrealize()
    7. xen_hvm_change_state_handler()
    8. cpu_ioreq_pio()
    9. xen_exit_notifier()

4. Replace TARGET_PAGE_SIZE with XC_PAGE_SIZE to match the page side with Xen.

f65f6ad5a7 aspeed: Introduce a "bmc-console" machine option
Most of the Aspeed machines use the UART5 device for the boot console,
and QEMU connects the first serial Chardev to this SoC device for this
purpose. See routine connect_serial_hds_to_uarts().

Nevertheless, some machines use another boot console, such as the fuji,
and commit 5d63d0c76c ("hw/arm/aspeed: Allow machine to set UART
default") introduced a SoC class attribute 'uart_default' and property
to be able to change the boot console device. It was later changed by
commit d2b3eaefb4 ("aspeed: Refactor UART init for multi-SoC machines").

The "bmc-console" machine option goes a step further and lets the user define
the UART device from the QEMU command line without introducing a new
machine definition. For instance, to use device UART3 (mapped on
/dev/ttyS2 under Linux) instead of the default UART5, one would use :

  -M ast2500-evb,bmc-console=uart3

48143e0fd2 hw/scsi/megasas: Silent GCC duplicated-cond warning
GCC9 is confused when building with CFLAG -O3:

  hw/scsi/megasas.c: In function ‘megasas_scsi_realize’:
  hw/scsi/megasas.c:2387:26: error: duplicated ‘if’ condition [-Werror=duplicated-cond]
   2387 |     } else if (s->fw_sge >= 128 - MFI_PASS_FRAME_SIZE) {
  hw/scsi/megasas.c:2385:19: note: previously used here
   2385 |     if (s->fw_sge >= MEGASAS_MAX_SGE - MFI_PASS_FRAME_SIZE) {
  cc1: all warnings being treated as errors

When this device was introduced in commit e8f943c3bc, the author
cared about modularity, using a definition for the firmware limit.

However if the firmware limit isn't changed (MEGASAS_MAX_SGE = 128),
the code ends doing the same check twice.

Per the maintainer [*]:

> The original code assumed that one could change MFI_PASS_FRAME_SIZE,
> but it turned out not to be possible as it's being hardcoded in the
> drivers themselves (even though the interface provides mechanisms to
> query it). So we can remove the duplicate lines.

Add the 'MEGASAS_MIN_SGE' definition for the '64' magic value,
slightly rewrite the condition check to simplify a bit the logic
and remove the unnecessary / duplicated check.

13bdfb8b54 riscv/virt: Support using pflash via -blockdev option
Currently, pflash devices can be configured only via -pflash
or -drive options. This is the legacy way and the
better way is to use -blockdev as in other architectures.
libvirt also has moved to use -blockdev method.

To support -blockdev option, pflash devices need to be
created in instance_init itself. So, update the code to
move the virt_flash_create() to instance_init. Also, use
standard interfaces to detect whether pflash0 is
configured or not.

4263e270a2 hw/riscv: virt: Assume M-mode FW in pflash0 only when "-bios none"
Currently, virt machine supports two pflash instances each with
32MB size. However, the first pflash is always assumed to
contain M-mode firmware and reset vector is set to this if
enabled. Hence, for S-mode payloads like EDK2, only one pflash
instance is available for use. This means both code and NV variables
of EDK2 will need to use the same pflash.

The OS distros keep the EDK2 FW code as readonly. When non-volatile
variables also need to share the same pflash, it is not possible
to keep it as readonly since variables need write access.

To resolve this issue, the code and NV variables need to be separated.
But in that case we need an extra flash. Hence, modify the convention
for non-KVM guests such that, pflash0 will contain the M-mode FW
only when "-bios none" option is used. Otherwise, pflash0 will contain
the S-mode payload FW. This enables both pflash instances available
for EDK2 use.

When KVM is enabled, pflash0 is always assumed to contain the
S-mode payload firmware only.

Example usage:
1) pflash0 containing M-mode FW
qemu-system-riscv64 -bios none -pflash <mmode_fw> -machine virt
or
qemu-system-riscv64 -bios none \
-drive file=<mmode_fw>,if=pflash,format=raw,unit=0 -machine virt

2) pflash0 containing S-mode payload like EDK2
qemu-system-riscv64 -pflash <smode_fw_code> -pflash <smode_vars> -machine  virt
or
qemu-system-riscv64 -bios <opensbi_fw> \
-pflash <smode_fw_code> \
-pflash <smode_vars> \
-machine  virt
or
qemu-system-riscv64 -bios <opensbi_fw> \
-drive file=<smode_fw_code>,if=pflash,format=raw,unit=0,readonly=on \
-drive file=<smode_fw_vars>,if=pflash,format=raw,unit=1 \
