Commit 9d7bd0826f introduced a new 'use-disabled-flag' property
set to true by default.
To allow the migration, we set this property to false in the hw_compat,
but in the wrong place (hw_compat_4_1).
Since commit 9d7bd0826f was released with QEMU 5.0, we move
'use-disabled-flag' property to hw_compat_4_2, so 4.2 machine types
will have the pre-patch behavior and the migration can work.
The issue was discovered with vhost-vsock device and 4.2 machine
type without running any kernel in the VM:
$ qemu-4.2 -M pc-q35-4.2,accel=kvm \
-device vhost-vsock-pci,guest-cid=4 \

$ qemu-5.2 -M pc-q35-4.2,accel=kvm \
-device vhost-vsock-pci,guest-cid=3 \
-monitor stdio
(qemu) migrate -d tcp:0:3333
# qemu-4.2 output

This property can be useful for distros to set up known-good ROM sizes for
migration purposes. The VM will fail to start if the ROM is too large,
and migration compatibility will not be broken if the ROM is too small.
Note that even though romsize is a uint32_t, it has to be between 1
(because empty ROM files are not accepted, and romsize must be greater
than the file) and 2^31 (because values above are not powers of two and
are rejected).

Displaying rendered resources requires blocking qemu GPU to avoid extra
framebuffer copies. For an external display, via Spice currently, there
is a callback to block/unblock the rendering in the same thread.
But with the vhost-user-gpu backend, the qemu process doesn't handle
the rendering itself, and the blocking callback isn't effective.
Instead, the backend must be notified when the display code is done.
Fix this by adding a new GraphicHwOps callback to indicate the GL state
is flushed, and we are done manipulating the shared GL resources. Call
it from gtk and spice display.

For the ECSPIx_CONREG register BURST_LENGTH field, the manual says:
0x020 A SPI burst contains the 1 LSB in first word and all 32 bits in second word.
0x021 A SPI burst contains the 2 LSB in first word and all 32 bits in second word.
Current logic uses either s->burst_length or 32, whichever smaller,
to determine how many bits it should read from the tx fifo each time.
For example, for a 48 bit burst length, current logic transfers the
first 32 bit from the first word in the tx fifo, followed by a 16
bit from the second word in the tx fifo, which is wrong. The correct
logic should be: transfer the first 16 bit from the first word in
the tx fifo, followed by a 32 bit from the second word in the tx fifo.
With this change, SPI flash can be successfully probed by U-Boot on
imx6 sabrelite board.

Create and connect the Clock input for the watchdog device on the
Stellaris boards. Because the Stellaris boards model the ability to
change the clock rate by programming PLL registers, we have to create
an output Clock on the ssys_state device and wire it up to the
watchdog.
Note that the old comment on ssys_calculate_system_clock() got the
units wrong -- system_clock_scale is in nanoseconds, not
milliseconds. Improve the commentary to clarify how we are
calculating the period.

While we transition the ARMSSE code from integer properties
specifying clock frequencies to Clock objects, we want to have the
device provide both at once. We want the final name of the main
input Clock to be "MAINCLK", following the hardware name.
Unfortunately creating an input Clock with a name X creates an
under-the-hood QOM property X; for "MAINCLK" this clashes with the
existing UINT32 property of that name.
Rename the UINT32 property to MAINCLK_FRQ so it can coexist with the
MAINCLK Clock; once the transition is complete MAINCLK_FRQ will be
deleted.

The ptimer API currently provides two methods for setting the period:
ptimer_set_period(), which takes a period in nanoseconds, and
ptimer_set_freq(), which takes a frequency in Hz. Neither of these
lines up nicely with the Clock API, because although both the Clock
and the ptimer track the frequency using a representation of whole
and fractional nanoseconds, conversion via either period-in-ns or
frequency-in-Hz will introduce a rounding error.
Add a new function ptimer_set_period_from_clock() which takes the
Clock object directly to avoid the rounding issues. This includes a
facility for the user to specify that there is a frequency divider
between the Clock proper and the timer, as some timer devices like
the CMSDK APB dualtimer need this.
To avoid having to drag in clock.h from ptimer.h we add the Clock
type to typedefs.h.

Currently, blk_is_read_only() tells whether a given BlockBackend can
only be used in read-only mode because its root node is read-only. Some
callers actually try to answer a slightly different question: Is the
BlockBackend configured to be writable, by taking write permissions on
the root node?
This can differ, for example, for CD-ROM devices which don't take write
permissions, but may be backed by a writable image file. scsi-cd allows
write requests to the drive if blk_is_read_only() returns false.
However, the write request will immediately run into an assertion
failure because the write permission is missing.
This patch introduces separate functions for both questions.
blk_supports_write_perm() answers the question whether the block
node/image file can support writable devices, whereas blk_is_writable()
tells whether the BlockBackend is currently configured to be writable.
All calls of blk_is_read_only() are converted to one of the two new
functions.

In commit 2f487a3d40 we fixed a problem observed with using the
vmware-vga device and the VNC UI frontend in a belt-and-braces
manner:
* we made the VNC frontend handle non-multiple-of-16 surface widths
* we rounded up the vmware-vga display width to a multiple of 16
However this introduced a spurious dependency of a device model on a
UI frontend header. vmware-vga isn't special and should not care
about what UI frontend it is using, and the VNC frontend needs to
handle arbitrary surface widths because other display device models
could use them. Moreover, even if the maximum width in vmware-vga is
made a multiple of 16, the guest itself can always program a
different width.
Remove the dependency on the VNC header. Since we have been using
the rounded-up width value since 2014, stick with it rather than
introducing a behaviour change, but don't calculate it by rounding up
to VNC_DIRTY_BITS_PER_PIXEL any more.

such hardware behavior, introduce a 'csum_flag' parameter to the
net_checksum_calculate() API to allow fine control over what type
checksum is calculated.
Existing users of this API are updated accordingly.

Per the "Physical Layer Specification Version 8.00" chapter 7.5.2,
"Data Read", there is a minimum 8 clock cycles (Nac) after the card
response and before data block shows up on the data out line. This
applies to both single and multiple block read operations.
Current implementation of single block read already satisfies the
timing requirement as in the RESPONSE state after all responses are
transferred the state remains unchanged. In the next 8 clock cycles
it jumps to DATA_START state if data is ready.
However we need an explicit state when expanding our support to
multiple block read in the future. Let's add a new state PREP_DATA
explicitly in the ssi-sd state machine to represent Nac.
Note we don't change the single block read state machine to let it
jump from RESPONSE state to DATA_START state as that effectively
generates a 16 clock cycles Nac, which might not be safe. As the
spec says the maximum Nac shall be calculated from several fields
encoded in the CSD register, we don't want to bother updating CSD
to ensure our Nac is within range to complicate things.

commit f6fb1f9b31 ("sdcard: Correct CRC16 offset in sd_function_switch()")
changed the 16-bit CRC to be stored at offset 64. In fact, this CRC
calculation is completely wrong. From the original codes, it wants
to calculate the CRC16 of the first 64 bytes of sd->data[], however
passing 64 as the `width` to sd_crc16() actually counts 256 bytes
starting from the `message` for the CRC16 calculation, which is not
what we want.
Besides that, it seems existing sd_crc16() algorithm does not match
the SD spec, which says CRC16 is the CCITT one but the calculation
does not produce expected result. It turns out the CRC16 was never
transferred outside the sd core, as in sd_read_byte() we see:
if (sd->data_offset >= 64)
sd->state = sd_transfer_state;
Given above reasons, let's drop it.

If a fid was actually re-opened by v9fs_reopen_fid(), we re-traverse the
fid list from the head in case some other request created a fid that
needs to be marked unreclaimable as well (i.e. the client opened a new
handle on the path that is being unlinked). This is suboptimal since
most if not all fids that require it have likely been taken care of
already.
This is mostly the result of new fids being added to the head of the
list. Since the list is now a QSIMPLEQ, add new fids at the end instead
to avoid the need to rewind. Take a reference on the fid to ensure it
doesn't go away during v9fs_reopen_fid() and that it can be safely
passed to QSIMPLEQ_NEXT() afterwards. Since the associated put_fid()
can also yield, same is done with the next fid. So the logic here is
to get a reference on a fid and only put it back during the next
iteration after we could get a reference on the next fid.

Currently the next-cube board code open-codes a lot of handling of
interrupts and some miscellaneous registers. Move this into a proper
QOM device.
In the real hardware this functionality seems to be the
responsibility of the Peripheral Controller (PC) chip, so name the
device that.
There are several different things that will need to be moved into
this device:
* the mmio_iops register set
* the scr_ops register set
* the next_irq IRQ handling
To ease review, we structure the change as a sequence of commits: in
this first commit we create the skeleton of the NeXTPC device with no
content, but with a backdoor pointer to the NeXTState machine's state
struct so we can move parts of the code and still have refactored and
non-refactored code using the same struct data fields. Further
commits will move functionality into the new device piece by piece.
At the end we will be able to remove the backdoor pointer because all
the data fields will be in the NeXTPC struct and not the NeXTState
struct.
We'll add the VMState for the new device at the end of all that; this
is in theory a migration compatibility break but this machine does
not currently support migration at all anyway.

Since commit 1e8b5b1aa1 ("spapr: Allow memory unplug to always succeed")
trying to unplug memory from a guest that doesn't support it (eg. rhel6)
no longer generates an error like it used to. Instead, it leaves the
memory around : only a subsequent reboot or manual use of drmgr within
the guest can complete the hot-unplug sequence. A flag was added to
SpaprMachineClass so that this new behavior only applies to the default
machine type.
We can do better. CAS processes all pending hot-unplug requests. This
means that we don't really care about what the guest supports if
the hot-unplug request happens before CAS.
All guests that we care for, even old ones, set enough bits in OV5
that lead to a non-empty bitmap in spapr->ov5_cas. Use that as a
heuristic to decide if CAS has already occured or not.
Always accept unplug requests that happen before CAS since CAS will
process them. Restore the previous behavior of rejecting them after
CAS when we know that the guest doesn't support memory hot-unplug.
This behavior is suitable for all machine types : this allows to
drop the pre_6_0_memory_unplug flag.

Use the PCI_BUS type cast macro to convert result of qdev_get_child_bus().
Also remove the check for NULL afterwards which should not be needed
because sysbus_create_simple() uses error_abort and we create the PCI
host object here that's expected to have a PCI bus so this shouldn't
fail. Even if it would fail that would be due to a programmer error so
an error message is not necessary.

Switch the ppc405_uc boards to directly creating and configuring the
UIC, rather than doing it via the old ppcuic_init() helper function.
We retain the API feature of ppc405ep_init() where it passes back
something allowing the callers to wire up devices to the UIC if
they need to, even though neither of the callsites currently makes
use of this ability -- instead of passing back the qemu_irq array
we pass back the UIC DeviceState.
This fixes a trivial Coverity-detected memory leak where
we were leaking the array of IRQs returned by ppcuic_init().

In commit 34d0831f38 the ppc-uic device was added, with a dcr-base
property. The intention was that the default value of dcr-base should be
the one that most of our boards need, so that in the common case they
don't need to specify a property value.
All QEMU boards with a UIC use a dcr-base of 0xc0, with the exception of
sam460ex which has four UICs and so puts them at 0xc0, 0xd0, 0xe0, 0xf0.
So 0xc0 is the obvious right choice for the default dcr-base.
The board code conversions in commits 0270d74ef8 (bamboo) and
c5ac9dc64f (virtex_ml507) assumed that default was 0xc0. Unfortunately
the actual default in 34d0831f38 was 0x30, by mistake, so the
bamboo and virtex_ml507 boards were broken as they were converted
away from ppcuic_init() (which always specifies the dcr_base property
value explicitly).
Set the default dcr-base to 0xc0 as was intended, fixing bamboo and
virtex_ml507.

This makes all of the internal interfaces architecture-independent and
renames the internal functions to use the 'common_semi' prefix instead
of 'arm' or 'arm_semi'.
To do this, some new architecture-specific internal helper functions
were created:
static inline target_ulong
common_semi_arg(CPUState *cs, int argno)
Returns the argno'th semihosting argument, where argno can be
either 0 or 1.
static inline void
common_semi_set_ret(CPUState *cs, target_ulong ret)
Sets the semihosting return value.
static inline bool
common_semi_sys_exit_extended(CPUState *cs, int nr)
This detects whether the specified semihosting call, which
is either TARGET_SYS_EXIT or TARGET_SYS_EXIT_EXTENDED should
be executed using the TARGET_SYS_EXIT_EXTENDED semantics.
static inline target_ulong
common_semi_rambase(CPUState *cs)
Returns the base of RAM region used for heap and stack. This
is used to construct plausible values for the SYS_HEAPINFO
call.
In addition, several existing functions have been changed to flag
areas of code which are architecture specific:
static target_ulong
common_semi_flen_buf(CPUState *cs)
Returns the current stack pointer minus 64, which is
where a stat structure will be placed on the stack
#define GET_ARG(n)
This fetches arguments from the semihosting command's argument
block. The address of this is available implicitly through the
local 'args' variable. This is *mostly* architecture
independent, but does depend on the current ABI's notion of
the size of a 'long' parameter, which may need run-time checks
(as it does on AARCH64)
#define SET_ARG(n, val)
This mirrors GET_ARG and stores data back into the argument
block.

There may be some differences in pci resource assignment between guest os
and firmware.
Eg. A Bridge with Bus [d2]
-+-[0000:d2]---01.0-[d3]----01.0
where [d2:01.00] is a pcie-pci-bridge with BAR0 (mem, 64-bit, non-pref) [size=256]
[d3:01.00] is a PCI Device with BAR0 (mem, 64-bit, pref) [size=128K]
BAR4 (mem, 64-bit, pref) [size=64M]
In EDK2, the Resource Map would be:
PciBus: Resource Map for Bridge [D2|01|00]
Type = PMem64; Base = 0x8004000000; Length = 0x4100000; Alignment = 0x3FFFFFF
Base = 0x8004000000; Length = 0x4000000; Alignment = 0x3FFFFFF; Owner = PCI [D3|01|00:20]
Base = 0x8008000000; Length = 0x20000; Alignment = 0x1FFFF; Owner = PCI [D3|01|00:10]
Type = Mem64; Base = 0x8008100000; Length = 0x100; Alignment = 0xFFF
It would use 0x4100000 to calculate the root bus's PMem64 resource window.
While in Linux, kernel will use 0x1FFFFFF as the alignment to calculate
the PMem64 size, which would be 0x6000000. So kernel would try to
allocate 0x6000000 from the PMem64 resource window, but since the window
size is 0x4100000 as assigned by EDK2, the allocation would fail.
The diffences could result in resource assignment failure.
Using _DSM #5 method to inform guest os not to ignore the PCI configuration
that firmware has done at boot time could handle the differences.

Currently, we place the DTB at 2MB from 4GB or end of DRAM which ever is
lesser. However, Linux kernel can address only 1GB of memory for RV32.
Thus, it can not map anything beyond 3GB (assuming 2GB is the starting address).
As a result, it can not process DT and panic if opensbi dynamic firmware
is used. While at it, place the DTB further away to avoid in memory placement
issues in future.
Fix this by placing the DTB at 16MB from 3GB or end of DRAM whichever is lower.

Depending on the client activity, the server can be asked to open a huge
number of file descriptors and eventually hit RLIMIT_NOFILE. This is
currently mitigated using a reclaim logic : the server closes the file
descriptors of idle fids, based on the assumption that it will be able
to re-open them later. This assumption doesn't hold of course if the
client requests the file to be unlinked. In this case, we loop on the
entire fid list and mark all related fids as unreclaimable (the reclaim
logic will just ignore them) and, of course, we open or re-open their
file descriptors if needed since we're about to unlink the file.
This is the purpose of v9fs_mark_fids_unreclaim(). Since the actual
opening of a file can cause the coroutine to yield, another client
request could possibly add a new fid that we may want to mark as
non-reclaimable as well. The loop is thus restarted if the re-open
request was actually transmitted to the backend. This is achieved
by keeping a reference on the first fid (head) before traversing
the list.
This is wrong in several ways:
- a potential clunk request from the client could tear the first
fid down and cause the reference to be stale. This leads to a
use-after-free error that can be detected with ASAN, using a
custom 9p client
- fids are added at the head of the list : restarting from the
previous head will always miss fids added by a some other
potential request
All these problems could be avoided if fids were being added at the
end of the list. This can be achieved with a QSIMPLEQ, but this is
probably too much change for a bug fix. For now let's keep it
simple and just restart the loop from the current head.

the slot into BLINKING_ON state for 5 seconds, and discovers at the end
that no device is actually inserted:

Worse, if the real device insertion happens within 5 seconds from the
apparent completion of the previous device removal (signaled via
DEVICE_DELETED event), the new button press will be interpreted as the
cancellation of that misguided powering on:

[13456.877101] shpchp 0000:01:00.0: PCI slot #2 - action canceled due to button press
As a result, the newly inserted device isn't brought up by the guest.
Avoid this situation by not pushing the attention button when the device
in the slot is in powered-off state and is being ejected.
FWIW pcie implementation doesn't suffer from this problem.

The PWM module is part of NPCM7XX module. Each NPCM7XX module has two
identical PWM modules. Each module contains 4 PWM entries. Each PWM has
two outputs: frequency and duty_cycle. Both are computed using inputs
from software side.
This module does not model detail pulse signals since it is expensive.
It also does not model interrupts and watchdogs that are dependant on
the detail models. The interfaces for these are left in the module so
that anyone in need for these functionalities can implement on their
own.
The user can read the duty cycle and frequency using qom-get command.

This patch allows NPCM7XX CLK module to compute clocks that are used by
other NPCM7XX modules.
Add a new struct NPCM7xxClockConverterState which represents a
single converter. Each clock converter in CLK module represents one
converter in NPCM7XX CLK Module(PLL, SEL or Divider). Each converter
takes one or more input clocks and converts them into one output clock.
They form a clock hierarchy in the CLK module and are responsible for
outputing clocks for various other modules in an NPCM7XX SoC.
Each converter has a function pointer called "convert" which represents
the unique logic for that converter.
The clock contains two initialization information: ConverterInitInfo and
ConverterConnectionInfo. They represent the vertices and edges in the
clock diagram respectively.

At present, when booting U-Boot on QEMU sabrelite, we see:
Net: Board Net Initialization Failed
No ethernet found.
U-Boot scans PHY at address 4/5/6/7 (see board_eth_init() in the
U-Boot source: board/boundary/nitrogen6x/nitrogen6x.c). On the real
board, the Ethernet PHY is at address 6. Adjust this by updating the
"fec-phy-num" property of the fsl_imx6 SoC object.
With this change, U-Boot sees the PHY but complains MAC address:
Net: using phy at 6
FEC [PRIME]
Error: FEC address not set.
This is due to U-Boot tries to read the MAC address from the fuse,
which QEMU does not have any valid content filled in. However this
does not prevent the Ethernet from working in QEMU. We just need to
set up the MAC address later in the U-Boot command shell, by:
=> setenv ethaddr 00:11:22:33:44:55

Support for running KVM on 32-bit Arm hosts was removed in commit
82bf7ae84c. You can still run a 32-bit guest on a 64-bit Arm
host CPU, but because Arm KVM requires the host and guest CPU types
to match, it is not possible to run a guest that requires a Cortex-A9
or Cortex-A15 CPU there. That means that the code in the
highbank/midway board models to support KVM is no longer used, and we
can delete it.

state. So let's remove the redundancy. Also, to make it easier to see
that machine->smp is the true source for "smp_cpus" and "max_cpus",
avoid passing them in function parameters, preferring instead to get
them from the state.

The sun4m board code connects both of the IRQ outputs of each ESCC to the
same slavio input qemu_irq. Connecting two qemu_irqs outputs directly to the
same input is not valid as it produces subtly wrong behaviour (for instance
if both the IRQ lines are high, and then one goes low, the PIC input will see
this as a high-to-low transition even though the second IRQ line should still
be holding it high).
This kind of wiring needs an explicitly created OR gate; add one.

Currently the GRLIB_IRQMP device is used in one place (the leon3 board),
but instead of the device providing inbound gpio lines for the board
to wire up, the board code itself calls qemu_allocate_irqs() with
the handler function being a set_irq function defined in the code
for the device.
Refactor this into the standard setup of a device having input
gpio lines.
This fixes a trivial Coverity memory leak report (the leon3
board code leaks the IRQ array returned from qemu_allocate_irqs()).

Per the "NCR89C105 Chip Specification" referenced in the header:
Chip-level Address Map
------------------------------------------------------------------
| 1D0 0000 -> | Counter/Timers | W,D |
| 1DF FFFF | | |
...
The address map indicated the allowed accesses at each address.
[...] W indicates a word access, and D indicates a double-word
access.
The SLAVIO timer controller is implemented expecting 32-bit accesses.
Commit a3d12d073e restricted the memory accesses to 32-bit, while
the device allows 64-bit accesses.
This was not an issue until commit 5d971f9e67 which reverted
("memory: accept mismatching sizes in memory_region_access_valid").
Fix by renaming .valid MemoryRegionOps as .impl, and add the valid
access range (W -> 4, D -> 8).
Since commit 21786c7e59 ("memory: Log invalid memory accesses")
this class of bug can be quickly debugged displaying 'guest_errors'
accesses, as:

It turns out that OPENPIC_KVM, XICS_KVM and XIVE_KVM are marked
to depend on KVM but this has no effect when minikconf runs in
allnoconfig mode. Such reverse dependencies should rather be
handled with a 'select' statement, eg.
config OPENPIC
select OPENPIC_KVM if KVM
or even better by getting rid of the intermediate _KVM config
and directly checking CONFIG_KVM in the meson.build file:
specific_ss.add(when: ['CONFIG_KVM', 'CONFIG_OPENPIC'],
if_true: files('openpic_kvm.c'))
Go for the latter with OPENPIC, XICS and XIVE.
This went unnoticed so far because CI doesn't test the build with

Documentation of object_child_foreach_recursive() clearly stipulates
that "it is forbidden to add or remove children from @obj from the @fn
callback". But this is exactly what we do during machine reset. The call
to spapr_drc_reset() can finalize the hot-unplug sequence of a PHB or a
PCI bridge, both of which will then in turn destroy their PCI DRCs. This
could potentially invalidate the iterator used by do_object_child_foreach().
It is pure luck that this haven't caused any issues so far.

Documentation of object_property_iter_init() clearly stipulates that

Change spapr_drc_reset() to return true if it caused a device to be
removed. Restart from scratch in this case. This can potentially

which generates a lot of LMB DRCs. But this kind of setup is rare,
and so is the use case of rebooting a guest while doing hot-unplug.

Non-transient DRCs are either in the empty or the ready state,
which means spapr_drc_reset() doesn't change their state. It
is thus not needed to do any checking. Call spapr_drc_reset()
unconditionally and squash spapr_drc_transient() into its
only user, spapr_drc_needed().

It is currently impossible to hot-unplug a memory device between
machine reset and CAS.
(qemu) device_del dimm1
Error: Memory hot unplug not supported for this guest
This limitation was introduced in order to provide an explicit
error path for older guests that didn't support hot-plug event
sources (and thus memory hot-unplug).
The linux kernel has been supporting these since 4.11. All recent
enough guests are thus capable of handling the removal of a memory
device at all time, including during early boot.
Lift the limitation for the latest machine type. This means that
trying to unplug memory from a guest that doesn't support it will
likely just do nothing and the memory will only get removed at
next reboot. Such older guests can still get the existing behavior
by using an older machine type.

Section 13.5.2 of LoPAPR mandates various DR related indentifiers
for all hot-pluggable entities to be exposed in the "ibm,drc-indexes",
"ibm,drc-power-domains", "ibm,drc-names" and "ibm,drc-types" properties
of their parent node. These properties are created with spapr_dt_drc().
PHBs and LMBs are both children of the machine. Their DR identifiers
are thus supposed to be exposed in the afore mentioned properties of
the root node.
When PHB hot-plug support was added, an extra call to spapr_dt_drc()
was introduced: this overwrites the existing properties, previously
populated with the LMB identifiers, and they end up containing only
PHB identifiers. This went unseen so far because linux doesn't care,
but this is still not conformant with LoPAPR.
Fortunately spapr_dt_drc() is able to handle multiple DR entity types
at the same time. Use that to handle DR indentifiers for PHBs and LMBs
with a single call to spapr_dt_drc(). While here also account for PMEM
DR identifiers, which were forgotten when NVDIMM hot-plug support was
added. Also add an assert to prevent further misuse of spapr_dt_drc().
With -m 1G,maxmem=2G,slots=8 passed on the QEMU command line we get:

Currently the PPC UIC ("Universal Interrupt Controller") is implemented
as a non-QOM device in ppc4xx_devs.c. Convert it to a proper QOM device
in hw/intc.
The ppcuic_init() function is retained for the moment with its current
interface; in subsequent commits this will be tidied up to avoid the
allocation of an irq array.
This conversion adds VMState support.
It leaves the LOG_UIC() macro as-is to maximise the extent to which
this is simply code-movement rather than a rewrite (in new code it
would be better to use tracepoints).
The default property values for dcr-base and use-vectors are set to
match those use by most of our boards with a UIC.

Add Loongson-3 based machine support, it use liointc as the interrupt
controler and use GPEX as the pci controller. Currently it can work with
both TCG and KVM.
As the machine model is not based on any exiting physical hardware, the
name of the machine is "loongson3-virt". It may be superseded in future
by a real machine model. If this happens, then a regular deprecation
procedure shall occur for "loongson3-virt" machine.
We now already have a full functional Linux kernel (based on Linux-5.4.x
LTS) here:
https://github.com/chenhuacai/linux
Of course the upstream kernel is also usable (the kvm host side and
guest side have both been upstream in Linux-5.9):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
How to use QEMU/Loongson-3?
1, Download kernel source from the above URL;
2, Build a kernel with arch/mips/configs/loongson3_defconfig;
3, Boot a Loongson-3A4000 host with this kernel (for KVM mode);
4, Build QEMU-master with this patchset;
5, modprobe kvm (only necessary for KVM mode);
6, Use QEMU with TCG:
qemu-system-mips64el -M loongson3-virt,accel=tcg -cpu Loongson-3A1000 -kernel <path_to_kernel> -append ...
Use QEMU with KVM:
qemu-system-mips64el -M loongson3-virt,accel=kvm -cpu Loongson-3A4000 -kernel <path_to_kernel> -append ...
The "-cpu" parameter is optional here and QEMU will use the correct type for TCG/KVM automatically.
