We add the ability to build legacy or current RSDP tables, based on the
AcpiRsdpData revision field passed to build_rsdp().
Although arm/virt only uses RSDP v2, adding that capability to
build_rsdp will allow us to share the RSDP build code between ARM and x86.

Instead of filling a mapped and packed C structure field in random order
and being careful about endianness and sizes, build_rsdp() now uses
build_append_int_noprefix() to compose RSDP table.

When RSDP table was introduced (d4bec5d87), we calculated only legacy
checksum, and that was incorrect as it
- specified rev=2 and forgot about extended checksum.
- legacy checksum calculated on full table instead of the 1st 20 bytes
Fix it by adding extended checksum calculation and using correct
size for legacy checksum.
While at it use explicit constants to specify sub/full tables
sizes instead of relying on AcpiRsdpDescriptor size and fields offsets.
The follow up commits will convert this table to build_append_int_noprefix() API,
will use constants anyway and remove unused AcpiRsdpDescriptor structure.

Commit af7d64ede0 (hw/arm/sysbus-fdt: Allow device matching with DT
compatible value) introduced a match_fn callback which gets called
for each registered combo to check whether a sysbus device can be
dynamically instantiated. However the callback gets called even if
the device type does not match the binding combo typename field.
This causes an assert when passing "-device ramfb" to the qemu
command line as vfio_platform_match() gets called on a non
vfio-platform device.
To fix this regression, let's change the add_fdt_node() logic so
that we first check the type and if the match_fn callback is defined,
then we also call it.
Binding combos only requesting a type check do not define the
match_fn callback.

In exynos4210_init() we allocate memory for an Exynos4210State
struct. Generally devices can assume that the memory allocated
for their state struct is zero-initialized; we broke that
assumption here by using g_new(). Use g_new0() instead.
(In particular, some code assumes that the various irq arrays
in the Exynos4210Irq sub-struct are zero-initialized.)
In the longer term, this code should be QOMified, and then
the struct memory will be allocated elsewhere and by functions
which always zero-initalize it; but for 3.1 this is a
simple fix.

In commit c79c0a314c we enabled emulation of external aborts
when the guest attempts to access a physical address with no
mapped device. In commit 4672cbd7be we suppress this for
most legacy boards to prevent breakage of previously working
guests, but we didn't suppress it in the 'virt' board, with
the rationale "we know that guests won't try to prod devices
that we don't describe in the device tree or ACPI tables". This
is mostly true, but we've had a report of a Linux guest image
that this did break. The problem seems to be that the guest
is (incorrectly) configured with a DEBUG_UART_PHYS value that
tells it there is a uart at 0x10009000 (which is true for
vexpress but not for virt), so in early bootup the kernel
probes this bogus address.
This is a misconfigured guest, so we don't need to worry
about it too much, but we can arrange that guests that ran
on QEMU v2.10 (before c79c0a314c) will still run on
the "virt-2.10" board model, by suppressing external aborts
only for that version and earlier. This seems a reasonable
compromise: "virt-2.10" is supposed to behave the same way
that "virt" did in the 2.10 release, and making it do that
provides a usable workaround for guests with bugs like this.

* the SCC_AID bits [23:20] specify the FPGA build target board revision,

Currently our PL080/PL081 model uses a combination of the CPU's
address space (via cpu_physical_memory_{read,write}()) and the
system address space for performing DMA accesses.
For the PL081s in the MPS FPGA images, their DMA accesses
must go via Master Security Controllers. Switch the
PL080/PL081 model to take a MemoryRegion property which
defines its downstream for making DMA accesses.
Since the PL08x are only used in two board models, we
make provision of the 'downstream' link mandatory and convert
both users at once, rather than having it be optional with
a default to the system address space.

Some ARM CPUs have bitbanded IO, a memory region that allows convenient
bit access via 32-bit memory loads/stores. This eliminates the need for
read-modify-update instruction sequences.
This patch makes this optional feature an ARMv7MState qdev property,
allowing boards to choose whether they want bitbanding or not.
Status of boards:
* iotkit (Cortex M33), no bitband
* mps2 (Cortex M3), bitband
* msf2 (Cortex M3), bitband
* stellaris (Cortex M3), bitband
* stm32f205 (Cortex M3), bitband
As a side-effect of this patch, Peter Maydell noted that the Ethernet
controller on mps2 board is now accessible. Previously they were hidden
by the bitband region (which does not exist on the real board).

This commit improve the way the GIC is realized and connected in the
ZynqMP SoC. The security extensions are enabled only if requested in the
machine state. The same goes for the virtualization extensions.
All the GIC to APU CPU(s) IRQ lines are now connected, including FIQ,
vIRQ and vFIQ. The missing CPU to GIC timers IRQ connections are also
added (HYP and SEC timers).
The GIC maintenance IRQs are back-wired to the correct GIC PPIs.
Finally, the MMIO mappings are reworked to take into account the ZynqMP
specifics. The GIC (v)CPU interface is aliased 16 times:
* for the first 0x1000 bytes from 0xf9010000 to 0xf901f000
* for the second 0x1000 bytes from 0xf9020000 to 0xf902f000
Mappings of the virtual interface and virtual CPU interface are mapped
only when virtualization extensions are requested. The
XlnxZynqMPGICRegion struct has been enhanced to be able to catch all
this information.

this device, you can quickly crash QEMU afterwards, e.g. with "info qtree":
echo "{'execute':'qmp_capabilities'} {'execute':'device_add', " \
"'arguments':{'driver':'bcm2837'}} {'execute': 'human-monitor-command', " \
"'arguments': {'command-line': 'info qtree'}}" | \

{"QMP": {"version": {"qemu": {"micro": 50, "minor": 12, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
{"error": {"class": "GenericError", "desc": "Device 'bcm2837' can not be
hotplugged on this machine"}}
Segmentation fault (core dumped)
The qdev_set_parent_bus() from instance_init adds a link to the child devices
which is not valid anymore after the bcm2837 instance has been destroyed.
Unfortunately, the child devices do not get destroyed / unlinked correctly
because both object_initialize() and object_property_add_child() increase
the reference count of the child objects by one, but only one reference
is dropped when the parent gets removed. So let's use the new functions
object_initialize_child() and sysbus_init_child_obj() instead to create
the objects, which will take care of creating the child objects with the
correct reference count of one.

These devices are currently causing some problems when a user is trying
to hot-plug or introspect them during runtime. Since these devices can
not be instantiated by the user at all (they need to be wired up in code
instead), we should mark them with user_creatable = false anyway, then we
avoid at least the crashes with the hot-plugging. The introspection problem
will be handled by a separate patch.

The timer controller can be driven by either an external 1MHz clock or
by the APB clock. Today, the model makes the assumption that the APB
frequency is always set to 24MHz but this is incorrect.
The AST2400 SoC on the palmetto machines uses a 48MHz input clock
source and the APB can be set to 48MHz. The consequence is a general
system slowdown. The QEMU machines using the AST2500 SoC do not seem
impacted today because the APB frequency is still set to 24MHz.
We fix the timer frequency for all SoCs by linking the Timer model to
the SCU model. The APB frequency driving the timers is now the one
configured for the SoC.

With a VGICv3 KVM device, if the number of vcpus exceeds the

we now attempt to register a second redistributor region. Up to
512 redistributors can fit in this latter on top of the 123 allowed

Registering this second redistributor region is possible if the
host kernel supports the following VGICv3 KVM device group/attribute:
KVM_DEV_ARM_VGIC_GRP_ADDR/KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION.
In case the host kernel does not support the registration of several

The Cortex-M CPU and its NVIC are two intimately intertwined parts of
the same hardware; it is not possible to use one without the other.
Unfortunately a lot of our board models don't do any sanity checking
on the CPU type the user asks for, so a command line like
qemu-system-arm -M versatilepb -cpu cortex-m3
will create an M3 without an NVIC, and coredump immediately.
In the other direction, trying a non-M-profile CPU in an M-profile
board won't blow up, but doesn't do anything useful either:
qemu-system-arm -M lm3s6965evb -cpu arm926
Add some checking in the NVIC and CPU realize functions that the
user isn't trying to use an NVIC without an M-profile CPU or
an M-profile CPU without an NVIC, so we can produce a helpful
error message rather than a core dump.

before we properly QOMified ARMv7M, and it has some flaws:
* it combines work that needs to be done by an SoC object (creating
and initializing the TYPE_ARMV7M object) with work that needs to
be done by the board model (setting the system up to load the ELF
file specified with -kernel)
* TYPE_ARMV7M creation failure is fatal, but an SoC object wants to
arrange to propagate the failure outward
* it uses allocate-and-create via qdev_create() whereas the current
preferred style for SoC objects is to do creation in-place
Board and SoC models can instead do the two jobs this function
was doing themselves, in the right places and with whatever their

acpi_data_push uses g_array_set_size to resize the memory size. If there
is no enough contiguous memory, the address will be changed. So previous
pointer could not be used any more. It must update the pointer and use
the new one.
Also, previous codes wrongly use le32 conversion of iort->node_offset
for subsequent computations that will result incorrect value if host is
not litlle endian. So use the non-converted one instead.

When QEMU is started with following CLI
-machine virt,gic-version=3,accel=kvm -cpu host -bios AAVMF_CODE.fd
it crashes with abort at
accel/kvm/kvm-all.c:2164:
KVM_SET_DEVICE_ATTR failed: Group 6 attr 0x000000000000c665: Invalid argument
Which is caused by implicit dependency of kvm_arm_gicv3_reset() on
arm_gicv3_icc_reset() where the later is called by CPU reset
reset callback.
However commit:
3b77f6c arm/boot: split load_dtb() from arm_load_kernel()
broke CPU reset callback registration in case
arm_load_kernel()
...
if (!info->kernel_filename || info->firmware_loaded)
branch is taken, i.e. it's sufficient to provide a firmware
or do not provide kernel on CLI to skip cpu reset callback
registration, where before offending commit the callback
has been registered unconditionally.
Fix it by registering the callback right at the beginning of
arm_load_kernel() unconditionally instead of doing it at the end.
NOTE:
we probably should eliminate that dependency anyways as well as
separate arch CPU reset parts from arm_load_kernel() into CPU
itself, but that refactoring that I probably would have to do
anyways later for CPU hotplug to work.

In cases where we don't set all the fields in the event struct

load_dtb() depends on arm_load_kernel() to figure out place
in RAM where it should be loaded, but it's not required for
arm_load_kernel() to work. Sometimes it's neccesary for
devices added with -device/device_add to be enumerated in
DTB as well, which's lead to [1] and surrounding commits to
add 2 more machine_done notifiers with non obvious ordering
to make dynamic sysbus devices initialization happen in
the right order.
However instead of moving whole arm_load_kernel() in to
machine_done, it's sufficient to move only load_dtb() into
virt_machine_done() notifier and remove ArmLoadKernelNotifier/
/PlatformBusFDTNotifierParams notifiers, which saves us ~90LOC
and simplifies code flow quite a bit.
Later would allow to consolidate DTB generation within one
function for 'mach-virt' board and make it reentrant so it
could generate updated DTB in device hotplug secenarios.
While at it rename load_dtb() to arm_load_dtb() since it's
public now.
Add additional field skip_dtb_autoload to struct arm_boot_info
to allow manual DTB load later in mach-virt and to avoid touching
all other boards to explicitly call arm_load_dtb().

platform-bus were using machine_done notifier to get and map
(assign irq/mmio resources) dynamically added sysbus devices
after all '-device' options had been processed.
That however creates non obvious dependencies on ordering of
machine_done notifiers and requires carefull line juggling
to keep it working. For example see comment above
create_platform_bus() and 'straitforward' arm_load_kernel()
had to converted to machine_done notifier and that lead to
yet another machine_done notifier to keep it working
arm_register_platform_bus_fdt_creator().
Instead of hiding resource assignment in platform-bus-device
to magically initialize sysbus devices, use device plug
callback and assign resources explicitly at board level
at the moment each -device option is being processed.
That adds a bunch of machine declaration boiler plate to
e500plat board, similar to ARM/x86 but gets rid of hidden
machine_done notifier and would allow to remove the dependent
notifiers in ARM code simplifying it and making code flow
easier to follow.

Adding it here won't make a difference in practice for most setups as we

However, enabling Jailhouse on top may introduce another controller, and
that one would like to have stable address as well. So the property is

The instance_init function of a device can be called at any time, even
if the device is not going to be used (i.e. not going to be realized).
So a instance_init function must not do things that could cause QEMU
to exit, like calling qemu_check_nic_model(&nd_table[0], ...) for example.
But this is what the instance_init function of the allwinner-a10 device
is currently doing - and this causes QEMU to quit unexpectedly when
you run the 'device-list-properties' QMP command for example:
$ echo "{'execute':'qmp_capabilities'}"\

... and QEMU quits after printing the last line (which should not happen

Instead of using "1.0" as the system version of SMBIOS, we should use
mc->name for mach-virt machine type to be consistent other architectures.
With this patch, "dmidecode -t 1" (e.g., "-M virt-2.12,accel=kvm") will
show:
Handle 0x0100, DMI type 1, 27 bytes

For backward compatibility, we allow older machine types to keep "1.0"
as the default system version.

The raspi3 has AArch64 CPUs, which means that our smpboot
code for keeping the secondary CPUs in a pen needs to have
a version for A64 as well as A32. Without this, the
secondary CPUs go into an infinite loop of taking undefined
instruction exceptions.

Now we have separate types for BCM2386 and BCM2387, we might as well
just hard-code the CPU type they use rather than having it passed
through as an object property. This then lets us put the initialization
of the CPU object in init rather than realize.
Note that this change means that it's no longer possible on
the command line to use -cpu to ask for a different kind of
CPU than the SoC supports. This was never a supported thing to
do anyway; we were just not sanity-checking the command line.
This does require us to only build the bcm2837 object on
TARGET_AARCH64 configs, since otherwise it won't instantiate
due to the missing cortex-a53 device and "make check" will fail.

The BCM2837 sets the Aff1 field of the MPIDR affinity values for the
CPUs to 0, whereas the BCM2836 uses 0xf. Set this correctly, as it
is required for Linux to boot.

The bcm2837 is pretty similar to the bcm2836, but it does have
some differences. Notably, the MPIDR affinity aff1 values it
sets for the CPUs are 0x0, rather than the 0xf that the bcm2836
uses, and if this is wrong Linux will not boot.
Rather than trying to have one device with properties that
configure it differently for the two cases, create two
separate QOM devices for the two SoCs. We use the same approach
as hw/arm/aspeed_soc.c and share code and have a data table
that might differ per-SoC. For the moment the two types don't
actually have different behaviour.

Our BCM2836 type is really a generic one that can be any of
the bcm283x family. Rename it accordingly. We change only
the names which are visible via the header file to the
rest of the QEMU code, leaving private function names
in bcm2836.c as they are.
This is a preliminary to making bcm283x be an abstract
parent class to specific types for the bcm2836 and bcm2837.

The TypeInfo and state struct for bcm2386 disagree about what the
parent class is -- the TypeInfo says it's TYPE_SYS_BUS_DEVICE,
but the BCM2386State struct only defines the parent_obj field
as DeviceState. This would have caused problems if anything
actually tried to treat the object as a TYPE_SYS_BUS_DEVICE.
Fix the TypeInfo to use TYPE_DEVICE as the parent, since we don't
need any of the additional functionality TYPE_SYS_BUS_DEVICE
provides.

If we're directly booting a Linux kernel and the CPU supports both
EL3 and EL2, we start the kernel in EL2, as it expects. We must also
set the SCR_EL3.HCE bit in this situation, so that the HVC
instruction is enabled rather than UNDEFing. Otherwise at least some
kernels will panic when trying to initialize KVM in the guest.

Add some assertions that if we're about to boot an AArch64 kernel,
the board code has not mistakenly set either secure_boot or
secure_board_setup. It doesn't make sense to set secure_boot,
because all AArch64 kernels must be booted in non-secure mode.
It might in theory make sense to set secure_board_setup, but
we don't currently support that, because only the AArch32
bootloader[] code calls this hook; bootloader_aarch64[] does not.
Since we don't have a current need for this functionality, just
assert that we don't try to use it. If it's needed we'll add
it later.

For the rpi1 and 2 we want to boot the Linux kernel via some
custom setup code that makes sure that the SMC instruction
acts as a no-op, because it's used for cache maintenance.
The rpi3 boots AArch64 kernels, which don't need SMC for
cache maintenance and always expect to be booted non-secure.
Don't fill in the aarch32-specific parts of the binfo struct.

Add support for passing 'max' to -machine gic-version. By analogy
with the -cpu max option, this picks the "best available" GIC version
whether you're using KVM or TCG, so it behaves like 'host' when
using KVM, and gives you GICv3 when using TCG.
Also like '-cpu host', using -machine gic-version=max' means there
is no guarantee of migration compatibility between QEMU versions;
in future 'max' might mean '4'.
