object_new(FOO) returns an object with ref_cnt == 1
and following
object_property_set_bool(cpuobj, true, "realized", NULL)
set parent of cpuobj to '/machine/unattached' which makes
ref_cnt == 2.
Since machvirt_init() doesn't take ownership of cpuobj
returned by object_new() it should explicitly drop
reference to cpuobj when dangling pointer is about to
go out of scope like it's done pc_new_cpu() to avoid
object leak.

Recent vanilla Raspberry Pi kernels started to make use of
the hardware random number generator in BCM2835 SoC. As a
result, those kernels wouldn't work anymore under QEMU
but rather just freeze during the boot process.
This patch implements a trivial BCM2835 compatible RNG,
and adds it as a peripheral to BCM2835 platform, which
allows to boot a vanilla Raspberry Pi kernel under Qemu.
Changes since v1:
* Prevented guest from writing [31..20] bits in rng_status
* Removed redundant minimum_version_id_old
* Added field entries for the state
* Changed realize function to reset

Block backends defined with "-drive if=T" with T other than "none" are
meant to be picked up by machine initialization code: a suitable
frontend gets created and wired up automatically.
Drives defined with if=scsi are also picked up by SCSI HBAs added with
-device, unlike other interface types. Deprecate this usage, as follows.
Create the frontends for onboard HBAs in machine initialization code,
exactly like we do for if=ide and other interface types. Change

units_per_default_bus = 1. This permits -drive if=ide,unit=1, which

if=ide drives not picked up that way can still be used with -device as
if they had if=none, but that's unclean and best avoided. Unused ones

-drive parameter "if" is optional, and the default depends on the
machine type. If a machine type doesn't specify a default, the
default is "ide".
Many machine types default to if=ide, even though they don't actually
have an IDE controller. A future patch will change these defaults to
something more sensible. To prepare for it, this patch makes default
"ide" explicit for the machines that actually pick up if=ide drives:

QEMU emulated hardware is always dma coherent with its guest. We do
annotate that correctly on the PCI host controller, but left out

Recent kernels have started to interpret that flag rather than take
dma coherency as granted with virtio-mmio. While that is considered
a kernel bug, as it breaks previously working systems, it showed that
our dt description is incomplete.
This patch adds the respective marker that allows guest OSs to evaluate
that our virtio-mmio devices are indeed cache coherent.

If we are giving the guest a CPU with EL2, it is likely to

providing PSCI to inner guest VMs. This makes using HVC
as the PSCI conduit for the outer QEMU a bad idea. We will
want to use SMC instead is this case: this makes sense
because QEMU's PSCI implementation is effectively an

The architectural timers in ARM CPUs all have level triggered interrupts
(unless you're using KVM on a host kernel before 4.4, which misimplemented
them as edge-triggered).
We were incorrectly describing them in the device tree as edge triggered.
This can cause problems for guest kernels in 4.8 before rc6:
* pre-4.8 kernels ignore the values in the DT
* 4.8 before rc6 write the DT values to the GIC config registers
* newer than rc6 ignore the DT and insist that the timer interrupts
are level triggered regardless
Fix the DT so we're describing reality. For backwards-compatibility
purposes, only do this for the virt-2.9 machine onward.

One of the purposes of VirtBoardInfo was to hold various
bits of state about the board. Now we have MachineState
and the subclass VirtMachineState to do this. Fold the
VirtBoardInfo into VirtMachineState rather than having
some flags in one struct and some in another with no
useful way to get between them.
In the process we drop the code for looking up the
memory map and irq map from the CPU model, because
in practice we always use the same maps in all cases.
For easier code review, this change removes the
VirtBoardInfo type but leaves all the variables which
used to be VirtBoardInfo* and are now VirtMachineState*
with their now-confusing 'vbi' names.

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.

* Commit 3e76099aac ("loader: Allow a custom AddressSpace when loading
ROMs") introduced the "Rom.as" field:
(1) It modified the utility callers of rom_insert() to take "as" as a
new parameter from *their* callers, and set "rom->as" from that
parameter. The functions covered were rom_add_file() and
rom_add_elf_program().
(2) It also modified rom_insert() itself, to auto-assign
"&address_space_memory", in case the external caller passed -- and
the utility caller forwarded -- as=NULL.
Except, commit 3e76099aac forgot to update the third utility caller of
rom_insert(), under point (1), namely rom_add_blob().
* Later, commit 5e774eb3bd ("loader: Add AddressSpace loading support
to uImages") added the load_uimage_as() function, and the
rom_add_blob_fixed_as() function-like macro, with the necessary changes
elsewhere to propagate the new "as" parameter to rom_add_blob():
load_uimage_as()
load_uboot_image()
rom_add_blob_fixed_as()
rom_add_blob()
At this point, the signature (and workings) of rom_add_blob() had been
broken already, and the rom_add_blob_fixed_as() macro passed its "_as"
parameter to rom_add_blob() as "callback_opaque". Given that the
"fw_callback" parameter itself was set to NULL (correctly), this did no
additional damage (the opaque arg would never be used), but ultimately
it broke the new functionality of load_uimage_as().
* The load_uimage_as() function would be put to use in one of the later
patches, commit e481a1f63c ("generic-loader: Add a generic loader").
* We can fix this only in a unified patch now. Append "AddressSpace *as"
to the signature of rom_add_blob(), and handle the new parameter. Pass
NULL from all current callers, except from rom_add_blob_fixed_as(),
where "_as" has to be bumped to the proper position.
* Note that rom_add_file() rejects the case when both "mr" and "as" are
passed in as non-NULL. The action that this is apparently supposed to
prevent is the
rom->mr = mr;
assignment (that's the only place where the "mr" parameter is used in
rom_add_file()). In rom_add_blob() though, we have no "mr" parameter,
and the actions done on the fw_cfg branch:
if (fw_file_name && fw_cfg) {
if (mc->rom_file_has_mr) {
data = rom_set_mr(rom, OBJECT(fw_cfg), devpath);
mr = rom->mr;
} else {
data = rom->data;
}
reflect those that are performed by rom_add_file() too (with mr==NULL):
if (rom->fw_file && fw_cfg) {
if ((!option_rom || mc->option_rom_has_mr) &&
mc->rom_file_has_mr) {
data = rom_set_mr(rom, OBJECT(fw_cfg), devpath);
} else {
data = rom->data;
}
Hence we need no additional restrictions in rom_add_blob().
* Stable is not affected as both problematic commits appeared first in
v2.8.0-rc0.

PC will use this field in other way, so move it outside the common

regardless of where they are coming from (-smp X | -device cpu...).
It's quick and dirty hack as it could be implemented in more generic
way in MashineClass. But do it in simple way since only PC is affected
so far.
Later we can generalize it when another affected target gets support

The SMC controllers on the Aspeed AST2500 SoC are very similar to the
ones found on the AST2400. The differences are on the number of
supported flash modules and their default mappings in the SoC address
space.
The Aspeed AST2500 has one SPI controller for the BMC firmware and two
for the host firmware. All controllers have now the same set of
registers compatible with the AST2400 FMC controller and the legacy
'SMC' controller is fully gone.
We keep the FMC object to act as the BMC SPI controller and add a new
SPI controller for the host. We also have to introduce new type names
to handle the differences in the flash modules memory mappping.

The qemu_chr_fe_write method will return -1 on EAGAIN if the
chardev backend write would block. Almost no callers of the
qemu_chr_fe_write() method check the return value, instead
blindly assuming data was successfully sent. In most cases
this will lead to silent data loss on interactive consoles,
but in some cases (eg RNG EGD) it'll just cause corruption
of the protocol being spoken.
We unfortunately can't fix the virtio-console code, due to
a bug in the Linux guest drivers, which would cause the
entire Linux kernel to hang if we delay processing of the
incoming data in any way. Fixing this requires first fixing
the guest driver to not hold spinlocks while writing to the

Current QEMU will stall guest VM booting under ACPI mode when vcpu count
is >= 12. Analyzing the booting log, it turns out that DSDT table can't
be loaded correctly due to "Invalid character(s) in name (0x62303043),
repaired: [C00*]". This is because existing QEMU uses a lower case AML
ID for CPU devices (e.g. C000, C001, ..., C00a, C00b). The ACPI code
inside guest VM detects this lower case character as an invalid character
(see acpi_ut_valid_acpi_char() in drivers/acpi/acpica/utstring.c file)
and converts it to "*". This causes duplicated IDs (i.e. "C00a" ==>"C00*"
and "C00b" ==> "C00*"). So ACPI refuses to load the table.
This patch fixes the problem by changing the format with a upper case
character. It matches the CPU ID formats used in other parts of QEMU
code.

The uboot in the previous release of the SDK was using a hardcoded

Below is a model for this device, only supporting unlock and
configuration. Without it, we endup running a guest with 64MB, which
is a bit low nowdays. It uses a 'silicon-rev' property and ram_size to
build a default value. Some bits should be linked to SCU strapping
registers but it seems a bit complex to add for the current need.

This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

we make the same adjustments for TCG as 64-bit KVM hosts. We neglect
to add consistency with 32-bit KVM hosts, as that would reduce SGI

As MPIDR is a system register, and thus guest visible, we only make

global properties are automatically applied to every new instance
of created CPU (at object_new() time), there is no point in
parsing cpu_model string every time a CPU created. So move
parsing outside CPU creation loop and do it only once.
Parsing also should be done before any CPU is created so that
features would affect the first CPU a well.

Currently CPUClass->parse_features() is used to parse -cpu
features string and set properties on created CPU instances.
But considering that features specified by -cpu apply to every
created CPU instance, it doesn't make sense to parse the same
features string for every CPU created. It also makes every target
that cares about parsing features string explicitly call
CPUClass->parse_features() parser, which gets in a way if we
consider using generic device_add for CPU hotplug as device_add
has not a clue about CPU specific hooks.
Turns out we can use global properties mechanism to set
properties on every created CPU instance for a given type. That
way it's possible to convert CPU features into a set of global
properties for CPU type specified by -cpu cpu_model and common
Device.device_post_init() will apply them to CPU of given type
automatically regardless whether it's manually created CPU or CPU
created with help of device_add.

In various Freescale SOCs, the GPT timers can be configured to select
its input clock.
Depending on the SOC the set of available input clocks may vary.
The actual single GPT definition was no good enough and because of it
booting the sabrelite board with a i.MX6DL device tree would fail
because of an incorrect input clock definition for the i.MX6DL SOC.
This patch fixes the i.MX6DL boot failure by adding the ability to
define a different set of input clocks depending on the considered SOC.
A different class has been defined for i.MX25, i.MX31 and i.MX6 each with
its specific set of input clocks.
The patch has been tested by booting KZM, i.MX25 PDK, i.MX6Q sabrelite
and i.MX6DL sabrelite.

Each controller on the ast2400 has a memory range on which it maps its
flash module slaves. Each slave is assigned a memory segment for its
mapping that can be changed at bootime with the Segment Address
Register. This is not supported in the current implementation so we
are using the defaults provided by the specs.
Each SPI flash slave can then be accessed in two modes: Command and
User. When in User mode, accesses to the memory segment of the slaves
are translated in SPI transfers. When in Command mode, the HW
generates the SPI commands automatically and the memory segment is
accessed as if doing a MMIO. Other SPI controllers call that mode
linear addressing mode.
For this purpose, we are adding below each crontoller an array of
structs gathering for each SPI flash module, a segment rank, a
MemoryRegion to handle the memory accesses and the associated SPI
slave device, which should be a m25p80.
Only the User mode is supported for now but we are preparing ground
for the Command mode. The framework is sufficient to support Linux.

The Aspeed AST2400 soc includes a static memory controller for the BMC
which supports NOR, NAND and SPI flash memory modules. This controller
has two modes : the SMC for the legacy interface which supports only
one module and the FMC for the new interface which supports up to five
modules. The AST2400 also includes a SPI only controller used for the
host firmware, commonly called BIOS on Intel. It can be used in three
mode : a SPI master, SPI slave and SPI pass-through
Below is the initial framework for the SMC controller (FMC mode only)
and the SPI controller: the sysbus object, MMIO for registers
configuration and controls. Each controller has a SPI bus and a
configurable number of CS lines for SPI flash slaves.
The differences between the controllers are small, so they are
abstracted using indirections on the register numbers.
Only SPI flash modules are supported.

Since QEMU performs cacheable accesses to guest memory when doing DMA
as part of the implementation of emulated PCI devices, guest drivers
should use cacheable accesses as well when running under KVM. Since this
essentially means that emulated PCI devices are DMA coherent, set the
'dma-coherent' DT property on the PCIe host controller DT node.
This brings the DT description into line with the ACPI description,
which already marks the PCI bridge as cache coherent (see commit
bc64b96c98).

The 32-bit ARM Linux kernel booting ABI requires that r0 is 0
when calling the kernel image. A bug in commit 10b8ec73e6
meant that for boards which use the write_board_setup hook (which
means "highbank", "midway", "raspi2" and "xilinx-zynq-a9") we
were incorrectly skipping the "clear r0" instruction in the
mini-bootloader. Use the right offset in the "add lr, pc, #n"
instruction so that we return from the board-setup code to the

timer_mod(fdctrl->result_timer,
qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

Both platform and PCI vfio drivers create a "slow", I/O memory region
with one or more mmap memory regions overlayed when supported by the
device. Generalize this to a set of common helpers in the core that
pulls the region info from vfio, fills the region data, configures
slow mapping, and adds helpers for comleting the mmap, enable/disable,
and teardown. This can be immediately used by the PCI MSI-X code,
which needs to mmap around the MSI-X vector table.
This also changes VFIORegion.mem to be dynamically allocated because
otherwise we don't know how the caller has allocated VFIORegion and
therefore don't know whether to unreference it to destroy the
MemoryRegion or not.

Some CPUs are of an opposite data-endianness to other components in the
system. Sometimes elfs have the data sections layed out with this CPU
data-endianness accounting for when loaded via the CPU, so byte swaps
(relative to other system components) will occur.
The leading example, is ARM's BE32 mode, which is is basically LE with
address manipulation on half-word and byte accesses to access the
hw/byte reversed address. This means that word data is invariant
across LE and BE32. This also means that instructions are still LE.
The expectation is that the elf will be loaded via the CPU in this
endianness scheme, which means the data in the elf is reversed at
compile time.
As QEMU loads via the system memory directly, rather than the CPU, we
need a mechanism to reverse elf data endianness to implement this
possibility.

If the user passes us an EL3 boot rom, then it is going to want to
implement the PSCI interface itself. In this case, disable QEMU's
internal PSCI implementation so it does not get in the way, and
instead start all CPUs in an SMP configuration at once (the boot
rom will catch them all and pen up the secondaries until needed).
The boot rom code is also responsible for editing the device tree
to include any necessary information about its own PSCI implementation
before eventually passing it to a NonSecure guest.
(This "start all CPUs at once" approach is what both ARM Trusted
Firmware and UEFI expect, since it is what the ARM Foundation Model
does; the other approach would be to provide some emulated hardware
for "start the secondaries" but this is simplest.)
This is a compatibility break, but I don't believe that anybody
was using a secure boot ROM with an SMP configuration. Such a setup
would be somewhat broken since there was nothing preventing nonsecure
guest code from calling the QEMU PSCI function to start up a secondary
core in a way that completely bypassed the secure world.

The virt board restricts guests to only 30GB of RAM. This is a
hangover from the vexpress-a15 board, and there's no inherent reason
for it. 30GB is smaller than you might reasonably want to provision
a VM for on a beefy server machine. Raise the limit to 255GB.
We choose 255GB because the available space we currently have
below the 1TB boundary is up to the 512GB mark, but we don't
want to paint ourselves into a corner by assigning it all to
RAM. So we make half of it available for RAM, with the 256GB..512GB
range available for future non-RAM expansion purposes.
If we need to provide more RAM to VMs in the future then we need to:
* allocate a second bank of RAM starting at 2TB and working up
* fix the DT and ACPI table generation code in QEMU to correctly
report two split lumps of RAM to the guest
* fix KVM in the host kernel to allow guests with >40 bit address spaces
The last of these is obviously the trickiest, but it seems
reasonable to assume that anybody configuring a VM with a quarter
of a terabyte of RAM will be doing it on a host with more than a
terabyte of physical address space.

Since build_rsdt() is implemented as common utility code (in
"hw/acpi/aml-build.c"), it should expose -- and forward -- the oem_id and
oem_table_id parameters between board code and the generic build_header()
function.

This patch is the continuation of commit 8870ca0e94 ("acpi: support
specified oem table id for build_header"). It will allow us to control the
OEM ID field too in the SDT header.

if (test_bit(i, cpuinfo->found_cpus))
is always true since loop handles only present CPUs
in range [0..smp_cpus).
But to fill usless cpuinfo->found_cpus we do unnecessary
scan over QOM tree to find the same CPUs.
So mark GICC as present always and drop not needed
code that fills cpuinfo->found_cpus.

This patch is the ACPI equivalent of "hw/arm/virt: Add always-on
property to the virt board timer". The timer is always on, and
thus setting this informs Linux that it may switch off the periodic
timer. Switching off the periodic timer substantially reduces the
number of interrupts the host needs to inject.
Testing note: AArch64 guests (the only ones currently booting with
ACPI) do not actually need this patch to determine it can turn the
periodic timer off. I therefore used a hacked guest kernel to ensure
this patch works as the equivalent DT patch does.

When booting the VM with UEFI, UEFI takes ownership of the RTC hardware.
While UEFI can use libfdt to disable the RTC device node in the DTB that
it passes to the OS, it cannot modify AML. Therefore, we won't generate
the RTC ACPI device at all when using UEFI.
