54a5ba13a9 target-arm: Implement BCM2835 hardware RNG
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

a64aa5785d hw: Deprecate -drive if=scsi with non-onboard HBAs
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
scsi_legacy_handle_cmdline() to create a frontend only when it's still
missing, and warn that this usage is deprecated.

2a7ae4ee50 hw/arm/highbank: Default -drive to if=ide instead of if=scsi
These machines have no onboard SCSI HBA, and no way to plug one.
-drive if=scsi therefore cannot work.  They do have an onboard IDE
controller (sysbus-ahci), but fail to honor if=ide.

Change their default to if=ide, and add a TODO comment on what needs
to be done to actually honor -drive if=ide.

7e465513c1 hw: Default -drive to if=none instead of scsi when scsi cannot work
Block backends defined with -drive if=scsi are meant to be picked up
by machine initialization code: a suitable frontend gets created and
wired up automatically.

if=scsi 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 produce an "Orphaned drive without device" warning.

A few machine types default to if=scsi, even though they don't
actually have a SCSI HBA.  This makes no sense.  Change their default
to if=none.  Affected machines:

* aarch64/arm: realview-pbx-a9 vexpress-a9 vexpress-a15 xilinx-zynq-a9

e0319b0302 hw/arm/cubieboard hw/arm/xlnx-ep108: Fix units_per_default_bus
Machine types cubieboard, xlnx-ep108, xlnx-zcu102 have an onboard AHCI
controller, but neglect to set their MachineClass member
units_per_default_bus = 1.  This permits -drive if=ide,unit=1, which
makes no sense for AHCI.  It also screws up index=N for odd N, because
it gets desugared to unit=1,bus=N/2

Doesn't really matter, because these machine types fail to honor
-drive if=ide.  Add the missing units_per_default_bus = 1 anyway,
along with a TODO comment on what needs to be done for -drive if=ide.

Also set block_default_type = IF_IDE explicitly.  It's currently the
default, but the next commit will change it to something more
sensible, and we want to keep the IF_IDE default for these three
machines.  See also the previous commit.

2059839baa hw: Default -drive to if=ide explicitly where it works
Block backends defined with -drive if=ide are meant to be picked up by
machine initialization code: a suitable frontend gets created and
wired up automatically.

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
produce an "Orphaned drive without device" warning.

-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:

* alpha: clipper
* arm/aarch64: spitz borzoi terrier tosa
* i386/x86_64: generic-pc-machine (with concrete subtypes pc-q35-*
  pc-i440fx-* pc-* isapc xenfv)
* mips64el: fulong2e
* mips/mipsel/mips64el: malta mips
* ppc/ppc64: mac99 g3beige prep
* sh4/sh4eb: r2d
* sparc64: sun4u sun4v

Note that ppc64 machine powernv already sets an "ide" default
explicitly.  Its IDE controller isn't implemented, yet.

054bb7b215 target-arm: Declare virtio-mmio as dma-coherent in dt
QEMU emulated hardware is always dma coherent with its guest. We do
annotate that correctly on the PCI host controller, but left out
virtio-mmio.

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.

d6f02ce3b8 target-arm: Enable vPMU support under TCG mode
This patch contains several fixes to enable vPMU under TCG mode. It
first removes the checking of kvm_enabled() while unsetting
ARM_FEATURE_PMU. With it, the .pmu option can be used to turn on/off vPMU
under TCG mode. Secondly the PMU node of DT table is now created under TCG.
The last fix is to disable the masking of PMUver field of ID_AA64DFR0_EL1.

For v7m we need to catch attempts to execute from special
addresses at 0xfffffff0 and above. Previously we did this
with the aid of a hacky special purpose lump of memory
in the address space and a check in translate.c for whether
we were translating code at those addresses.

We can implement this more cleanly using a CPU
unassigned access handler which throws the exception
if the unassigned access is for one of the special addresses.

2013c5665c hw/arm/virt: Support using SMC for PSCI
If we are giving the guest a CPU with EL2, it is likely to
want to use the HVC instruction itself, for instance for
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
emulation of functionality provided by EL3 firmware.

Add code to support selecting the PSCI conduit to use,
rather than hardcoding use of HVC.

ebfcc03bf7 hw/arm/virt-acpi - reserve ECAM space as PNP0C02 device
Linux for arm64 v4.10 and later will complain if the ECAM config space is
not reserved in the ACPI namespace:

  acpi PNP0A08:00: [Firmware Bug]: ECAM area [mem 0x3f000000-0x3fffffff] not reserved in ACPI namespace

The rationale is that OSes that don't consume the MCFG table should still
be able to infer that the PCI config space MMIO region is occupied.

So update the ACPI table generation routine to add this reservation.

abf3a4e5ee arm: virt: Fix segmentation fault when specifying an unsupported CPU
Using -cpu cortex-a9 (or any other unsupported CPU) with the virt
board will cause QEMU to segmentation fault.  This bug was introduced
in commit 9ac4ef77, which incorrectly added a NULL terminator when
converting the VirtBoardInfo array into a simple array of strings
defining the valid CPUs. The cpuname_valid() loop already has
a termination condition based on ARRAY_SIZE, so the NULL is
spurious and causes the strcmp() to segfault if we reach it.
Delete the NULL.

Useful to send guest data back to QEMU.

Changes from Laszlo Ersek <lersek@redhat.com>:
- rebase the patch from Michael Tsirkin's original postings at [1] and [2]
  to the following patches:
  - loader: Allow a custom AddressSpace when loading ROMs
  - loader: Add AddressSpace loading support to uImages
  - loader: fix handling of custom address spaces when adding ROM blobs
- reject such writes immediately that would exceed the end of the array,
  rather than performing a partial write before setting the error bit: see
  the (len != dma.length) condition
- document the write interface

156bc9a5ea hw/arm/virt: Don't incorrectly claim architectural timer to be edge-triggered
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*

fcf5ef2ab5 Move target-* CPU file into a target/ folder
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.

aa6c6ae843 loader: fix handling of custom address spaces when adding ROM blobs
* 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.

5836d16812 fw_cfg: move FW_CFG_NB_CPUS out of fw_cfg_init1()
PC will use this field in other way, so move it outside the common
code so PC could set a different value, i.e. all CPUs
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
for -device cpu.

The versatilepb physical address space layout only has

on the amount of RAM requested by the user we would happily
create a RAM area that overlapped with the devices, resulting

RAM than the board can handle (as we do already for some
other board models).

a61ae7f88c and thus unused. The only user, the malta FGPA display has
been converted to use an event "opened" callback instead.

08426da7dd pxa2xx: Auto-assign name for i2c bus in i2c_init_bus.
If a name is provided, the same name is assigned to both the I2C
controllers. Leaving it NULL, causes names to be automatically
assigned with an ID suffix, giving unique names to each
controller. This helps us to uniquely identify each controller in the
device tree, for example when adding an I2C device.

When kernel and device tree are specified in the QEMU commandline, then
this device tree may be modified e.g. to add virtio_mmio devices.
With a bootloader e.g. on a flash device these extra devices are not
available.
With this change, the device tree can be specified at the QEMU commandline.
The modified device tree made available to the bootloader with the same
mechanism already supported by device trees fully generated by QEMU.

6dc52326cc aspeed: add support for the AST2500 SoC SMC controllers
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.

0e5803dfbc aspeed: rename the smc object to fmc
The Aspeed SoC has three different types of SMC (Static Memory
Controller) controllers: the SMC (legacy), the FMC (the new one) and
the SPI for the host PNOR. The FMC and the SPI models are now
converging on the AST2500 SoC and the SMC, which was still available
on the AST2400 SoC, was removed.

The Aspeed SoC does not provide support for the legacy SMC
controller. So, let's rename the 'smc' object to 'fmc' to clarify its
nature.

6ab3fc32ea hw: replace most use of qemu_chr_fe_write with qemu_chr_fe_write_all
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
hvc device backend.

f460be435f ARM: ACPI: fix the AML ID format for CPU devices
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.

c2da8a8b90 ast2400: add a memory controller device model
The uboot in the previous release of the SDK was using a hardcoded
value for memory size. This is not true anymore, the value is now
retrieved from the memory controller.

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.

The model is ready for the AST2500 SOC.

f394b2e20d qapi: Change Netdev into a flat union
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.

95eb49c8a3 hw/arm/virt: tcg: adjust MPIDR like KVM
KVM adjusts the MPIDR of guest vcpus based on the architecture of
the host, 32-bit vs. 64-bit, and, for 64-bit, also on the type of
GIC the guest is using. To be consistent and improve SGI efficiency
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
efficiency and KVM is expected to change.

As MPIDR is a system register, and thus guest visible, we only make
adjustments for current and later versioned machines.

of created CPU (at object_new() time), there is no point in

62a48a2a57 cpu: Use CPUClass->parse_features() as convertor to global properties
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.

66542f6399 i.MX: split the GPT timer implementation into per SOC definitions
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.

924ed16386 ast2400: add SPI flash slaves
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

if option '-machine secure=on' is provided.

The function create_uart is called twice. So make CharDriverState pointer
a parameter to create_uart instead of hardcoded.

28213cb6a6 acpi: make bios_linker_loader_add_checksum() API offset based
It should help to make clear that bios_linker works in terms
of offsets within a file. Also it should prevent mistakes
where user passes as arguments pointers to unrelated to file blobs.

While at it, considering that it's a ACPI checksum and
it's initial value must be 0, move checksum field zeroing
into bios_linker_loader_add_checksum() instead of doing it
at every call site manually before bios_linker_loader_add_checksum()
is called.

In addition add extra boundary checks.

ad9671b870 acpi: simplify bios_linker API by removing redundant 'table' argument
'table' argument in bios_linker_add_foo() commands is
a data blob of one of files also passed to the same API.
So instead of passing blob in every API call, add and keep
file name association with related blob at bios_linker_loader_alloc()
time.

And find blob by name looking up allocated file entries
inside of bios_linker_add_foo() commands.

It will:
 - make API less confusing,
 - enforce calling bios_linker_loader_alloc() before
   calling any bios_linker_add_foo()
 - make sure that blob is the correct one, i.e.
   associated with the right file name

The Aspeed AST2400 integrates a set of 14 I2C/SMBus bus controllers
directly connected to the APB bus. They can be programmed as master or
slave but the propopsed model only supports the master mode.

On the TODO list, we also have :

 - improve and harden the state machine.
 - bus recovery support (used by the Linux driver).
 - transfer mode state machine bits. this is not strictly necessary as
   it is mostly used for debug. The bus busy bit is deducted from the
   I2C core engine of qemu.
 - support of the pool buffer: 2048 bytes of internal SRAM (not used
   by the Linux driver).

b4850e5ae9 hw/arm/boot: always clear r0 when booting kernels
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
correct place.

73bcb24d93 Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND
This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed.  This replacement improves the readability and
understandability of code.

For example,

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

NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
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.

db0da029a1 vfio: Generalize region support
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.

7ef295ea5b loader: Add data swap option to load-elf
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.

4824a61a6d hw/arm/virt: Assume EL3 boot rom will handle PSCI if one is provided
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.

71c2768433 virt: Lift the maximum RAM limit from 30GB to 255GB
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.

cf5a13e370 hw/arm/sysbus-fdt: enable amd-xgbe dynamic instantiation
This patch allows the instantiation of the vfio-amd-xgbe device
from the QEMU command line (-device vfio-amd-xgbe,host="<device>").

The guest is exposed with a device tree node that combines the description
of both XGBE and PHY (representation supported from 4.2 onwards kernel):
Documentation/devicetree/bindings/net/amd-xgbe.txt.

There are 5 register regions, 6 interrupts including 4 optional
edge-sensitive per-channel interrupts.

Some property values are inherited from host device tree. Host device tree
must feature a combined XGBE/PHY representation (>= 4.2 host kernel).

2 clock nodes (dma and ptp) also are created. It is checked those clocks
are fixed on host side.

AMD XGBE node creation function has a dependency on vfio Linux header and
more generally node creation function for VFIO platform devices only make
sense with CONFIG_LINUX so let's protect this code with #ifdef CONFIG_LINUX.

9481cf2e5f hw/arm/sysbus-fdt: helpers for clock node generation
Some passthrough'ed devices depend on clock nodes. Those need to be
generated in the guest device tree. This patch introduces some helpers
to build a clock node from information retrieved in the host device tree.

- copy_properties_from_host copies properties from a host device tree
  node to a guest device tree node
- fdt_build_clock_node builds a guest clock node and checks the host
  fellow clock is a fixed one.

fdt_build_clock_node will become static as soon as it gets used. A
dummy pre-declaration is needed for compilation of this patch.

58e71097ce device_tree: qemu_fdt_getprop_cell converted to use the error API
This patch aligns the prototype with qemu_fdt_getprop. The caller
can choose whether the function self-asserts on error (passing
&error_fatal as Error ** argument, corresponding to the legacy behavior),
or behaves differently such as simply output a message.

In this later case the caller can use the new lenp parameter to interpret
the error if any.

a43e68a08b virt-acpi-build: add always-on property for timer
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.

dc3b89ef87 xlnx-zynqmp: Add support for high DDR memory regions
The Xilinx ZynqMP SoC and EP108 board supports three memory regions:
 - A 2GB region starting at 0
 - A 32GB region starting at 32GB
 - A 256GB region starting at 768GB

This patch adds support for the first two memory regions, which is
automatically created based on the size specified by the QEMU memory
command line argument.

On hardware the physical memory region is one continuous region, it is then
mapped into the three different regions by the DDRC. As we don't model the
DDRC this is done at startup by QEMU. The board creates the memory region and
then passes that memory region to the SoC. The SoC then maps the memory
regions.

virt_set_gic_version() calls exit(1) when passed an invalid property
value.  Property setters are not supposed to do that.  Screwed up in
commit b92ad39.  Harmless, because the property belongs to a machine.
Set an error object instead.

c525436e69 hw: Don't use hw_error() for machine initialization errors
Printing CPU registers is not helpful during machine initialization.
Moreover, these are straightforward configuration or "can get
resources" errors, so dumping core isn't appropriate either.  Replace
hw_error() by error_report(); exit(1).  Matches how we report these
errors in other machine initializations.

3f8752b4e5 fw_cfg: remove offset argument from callback prototype
Read callbacks are now only invoked at item selection, before any
data is read. As such, the value of the offset argument passed to
the callback will always be 0. Also, the two callback instances
currently in use both leave their offset argument unused.

This patch removes the offset argument from the fw_cfg read callback
prototype, and from the currently available instances. The unused
(write) callback prototype is also removed (write support was removed
earlier, in commit 023e3148).

40340e5f22 arm: highbank: Implement PSCI and dummy monitor
Firstly, enable monitor mode and PSCI, both of which are features of
this board.

In addition to PSCI, this board also uses SMC for cache maintenance
ops. This means we need a secure monitor to catch these and nop them.
Use the ARM boot board-setup feature to implement this. The SMC trap
implements the needed nop while all other traps will pen the CPU.

As a KVM CPU cannot run in secure mode, do not do the board-setup if
not running TCG. Report a warning explaining the limitation in this
case.

The software then returns to the bootloader via the link register. This

for existing firmware support).

The blob is loaded by a callback if and only if doing a linux boot
(similar to the existing write_secondary support).

4b280b726a hw/arm/virt: don't use a15memmap directly
We should always go through VirtBoardInfo when we need the memmap.
To avoid using a15memmap directly, in this case, we need to defer
the max-cpus check from class init time to instance init time. In
class init we now use MAX_CPUMASK_BITS for max_cpus initialization,
which is the maximum QEMU supports, and also, incidentally, the
maximum KVM/gicv3 currently supports. Also, a nice side-effect of
delaying the max-cpus check is that we now get more appropriate
error messages for gicv2 machines that try to configure more than
123 cpus. Before this patch it would complain that the requested
number of cpus was greater than 123, but for gicv2 configs, it
should complain that the number is greater than 8.

bab27ea2e3 hw/arm/virt: smbios: inform guest of kvm
ARM/AArch64 KVM guests don't have any way to identify
themselves as KVM guests (x86 guests use a CPUID leaf). Now, we
could discuss all sorts of reasons why guests shouldn't need to
know that, but then there's always some case where it'd be
nice... Anyway, now that we have SMBIOS tables in ARM guests,
it's easy for the guest to know that it's a QEMU instance. This
patch takes that one step further, also identifying KVM, when
appropriate. Again, we could debate why generally nothing
should care whether it's of type QEMU or QEMU/KVM, but again,
sometimes it's nice to know...

4c315c2766 qdev: Protect device-list-properties against broken devices
Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.

This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties.  Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1.  Example reproducer:

    $ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
    {"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
    { "execute": "qmp_capabilities" }
    {"return": {}}
    { "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
    qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
    Aborted (core dumped)
    [Exit 134 (SIGABRT)]

Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:

* Hang during cleanup (didn't debug, so I can't say why):
  "realview_pci", "versatile_pci".

* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",
  "fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such
  CPUs

* Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu",
  "host-powerpc64-cpu", "host-embedded-powerpc-cpu",
  "host-powerpc-cpu" (the powerpc ones can't currently reach the
  assertion, because the CPUs are only registered when KVM is enabled,
  but the assertion is arguably in the wrong place all the same)

Make qmp_device_list_properties() fail cleanly when the device is so
marked.  This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails".  Not a complete fix, just
a better-than-nothing work-around.  In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".

This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2.  Example reproducer:

    $ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help

Before:

    qemu-system-aarch64: .../memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.

After:

    Can't list properties of device 'pxa2xx-pcmcia'

This causes the region to outlive the object, because it attaches the
region to /machine.  This is not nice for the "realize" method, but
much worse for "instance_init" because it can cause dangling pointers
after a simple object_new/object_unref pair.

b597c3f7da arm: Remove ELF_MACHINE from cpu.h
The only generic code relying on this is linux-user. Linux user
already has a lot of #ifdef TARGET_ customisation so instead, define
ELF_ARCH as either EM_ARM or EM_AARCH64 appropriately.

The armv7m bootloader can just pass EM_ARM directly, as that
is architecture specific code. Note that arm_boot already has its own
logic selecting an arm specific elf machine so this makes V7M more
consistent with arm_boot.

This removes another architecture specific definition from the global
namespace.

While virt machine creates two flash devices with total size 0x08000000,
the ACPI table generation code was wrongly using this total size as the
size of each flash device, so it would overlap other MMIO spaces.
Make each device entry in the table half the total; this brings the
ACPI table into line with the code which generates the device tree
and which creates the flash devices themselves.

f8ed85ac99 Fix bad error handling after memory_region_init_ram()
Symptom:

    $ qemu-system-x86_64 -m 10000000
    Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
    upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
    Aborted (core dumped)

Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions.  Before the commit, we report the error and exit(1), in
one place, ram_block_add().  The commit lifts the error handling up
the call chain some, to three places.  Fine.  Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".

The three places are:

* memory_region_init_ram()

  Commit 4994653 (right after commit ef701d7) lifted the error
  handling further, through memory_region_init_ram(), multiplying the
  incorrect use of &error_abort.  Later on, imitation of existing
  (bad) code may have created more.

* memory_region_init_ram_ptr()

  The &error_abort is still there.

* memory_region_init_rom_device()

  Doesn't need fixing, because commit 33e0eb5 (soon after commit
  ef701d7) lifted the error handling further, and in the process
  changed it from &error_abort to passing it up the call chain.
  Correct, because the callers are realize() methods.

Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:

    @r@
    expression mr, owner, name, size, err;
    position p;
    @@
            memory_region_init_ram(mr, owner, name, size,
    (
    -                              &error_abort
    +                              &error_fatal
    |
                                   err@p
    )
                                  );
    @script:python@
        p << r.p;
    @@
    print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)

When the last argument is &error_abort, it gets replaced by
&error_fatal.  This is the fix.

If the last argument is anything else, its position is reported.  This
lets us check the fix is complete.  Four positions get reported:

* ram_backend_memory_alloc()

  Error is passed up the call chain, ultimately through
  user_creatable_complete().  As far as I can tell, it's callers all
  handle the error sanely.

* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()

  DeviceClass.realize() methods, errors handled sanely further up the
  call chain.

We're good.  Test case again behaves:

    $ qemu-system-x86_64 -m 10000000
    qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory
    [Exit 1 ]

The next commits will repair the rest of commit ef701d7's damage.

2d710006a0 hw/arm/virt: Default to not providing TrustZone support
Switch the default for the 'virt' board to not providing TrustZone
support in either the CPU or the GIC. This is primarily for the
benefit of UEFI, which currently assumes there is no TrustZone
support, and does not set the GIC up correctly if it is TZ-aware.
It also means the board is consistent about its behaviour whether
we're using KVM or TCG (KVM never has TrustZone support).

If TrustZone support is required (for instance for running test
suites or TZ-aware firmware) it can be enabled with the
"-machine secure=on" command line option.

d8b1ae4237 hw/arm: new interface for devices which need to behave differently for kernel boot
For ARM we have a little minimalist bootloader in hw/arm/boot.c which
takes the place of firmware if we're directly booting a Linux kernel.
Unfortunately a few devices need special case handling in this situation
to do the initialization which on real hardware would be done by
firmware. (In particular if we're booting a kernel in NonSecure state
then we need to make a TZ-aware GIC put all its interrupts into Group 1,
or the guest will be unable to use them.)

Create a new QOM interface which can be implemented by devices which
need to do something different from their default reset behaviour.
The callback will be called after machine initialization and before
first reset.

Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

sizeof(T).

76e2aef392 hw/arm/boot: Increase fdt alignment
The Linux kernel on aarch64 creates a page table entry at early bootup
that spans the 2MB range on memory spanning the fdt start address:

  [ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ]

This means that when our current 4k alignment happens to fall at the end
of the aligned region, Linux tries to access memory that is not mapped.

The easy fix is to instead increase the alignment to 2MB, making Linux's
logic always succeed.

We leave the existing 4k alignment for 32bit kernels to not cause any
regressions due to space constraints.

4e2c0b2a4a hw/arm/virt: Make block devices default to virtio
Now we have virtio-pci, we can make the virt board's default block
device type be IF_VIRTIO. This allows users to use simplified
command lines that don't have to explicitly create virtio-pci-blk
devices; the -hda &c very short options now also work.

This means we also need to set no_cdrom to avoid getting a
default cdrom device -- this is needed because the virtio-blk
device will fail if it is connected to a block backend with
no media, which is what the default cdrom device typically is.
Providing a cdrom with media via -cdrom will succeed, but silently
create a device with non-removable medium. this is probably
not really what the user wants, but is the best we can do now.

Note that this change means that some command lines which used
to work (by accident) will stop working. Where a drive was connected
manually to a device but without 'if=none' being specified, we
used to treat this as an IDE drive, which we would then not autoplug
because the board doesn't support IDE. Now we will treat it as a
virtio disk and autoplug it, which means the attempt to use the
drive manually will fail:
  qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is already
  in use because it has been automatically connected to another device
  (did you need 'if=none' in the drive options?)
The command line will have to be changed to include 'if=none', as the
error message suggests.

5f7a5a0edc hw/arm/virt: add dynamic sysbus device support
Allows sysbus devices to be instantiated from command line by
using -device option. Machvirt creates a platform bus at init.
The dynamic sysbus devices are attached to this platform bus device.

The platform bus device registers a machine init done notifier
whose role will be to bind the dynamic sysbus devices. Indeed
dynamic sysbus devices are created after machine init.

machvirt also registers a notifier that will build the device
tree nodes for the platform bus and its children dynamic sysbus
devices.

ac9d32e396 hw/arm/boot: arm_load_kernel implemented as a machine init done notifier
Device tree nodes for the platform bus and its children dynamic sysbus
devices are added in a machine init done notifier. To load the dtb once,
after those latter nodes are built and before ROM freeze, the actual
arm_load_kernel existing code is moved into a notifier notify function,
arm_load_kernel_notify. arm_load_kernel now only registers the
corresponding notifier.

Machine files that do not support platform bus stay unchanged. Machine
files willing to support dynamic sysbus devices must call arm_load_kernel
before sysbus-fdt arm_register_platform_bus_fdt_creator to make sure
dynamic sysbus device nodes are integrated in the dtb.

f5d8c8cd79 hw/arm/virt-acpi-build: Basic framework for building ACPI tables on ARM
Introduce a preliminary framework in virt-acpi-build.c with the main
ACPI build functions. It exposes the generated ACPI contents to
guest over fw_cfg.

The required ACPI v5.1 tables for ARM are:
- RSDP: Initial table that points to XSDT
- RSDT: Points to FADT GTDT MADT tables
- FADT: Generic information about the machine
- GTDT: Generic timer description table
- MADT: Multiple APIC description table
- DSDT: Holds all information about system devices/peripherals, pointed by FADT

There are a number of ffs(3) callers that do roughly:

  bit = ffs(val);
  if (bit) {
      do_something(bit - 1);
  }

This pattern can be converted to ctz32() like this:

  zeroes = ctz32(val);
  if (zeroes != 32) {
      do_something(zeroes);
  }

The call sites have been audited to ensure the ffs(0) - 1 == -1 case

Commit 0b183fc871:"memory: move mem_path handling to

memory_region_init_ram_from_file. Also it moved mem-path handling a step
up from memory_region_init_ram to memory_region_allocate_system_memory.

Therefore for any board that uses memory_region_init_ram directly,
-mem-path is not supported.

Fix this by replacing memory_region_init_ram with
memory_region_allocate_system_memory.

9f9bdf43ca sysbus: Make devices picking up backends unavailable with -device
Device models aren't supposed to go on fishing expeditions for
backends.  They should expose suitable properties for the user to set.
For onboard devices, board code sets them.

A number of sysbus devices pick up block backends in their init() /
instance_init() methods with drive_get_next() instead: sl-nand,
milkymist-memcard, pl181, generic-sdhci.

Likewise, a number of sysbus devices pick up character backends in
their init() / realize() methods with qemu_char_get_next_serial():
cadence_uart, digic-uart, etraxfs,serial, lm32-juart, lm32-uart,
milkymist-uart, pl011, stm32f2xx-usart, xlnx.xps-uartlite.

All these mistakes are already marked FIXME.  See the commit that
added these FIXMEs for a more detailed explanation of what's wrong.

Fortunately, only machines ppce500 and pseries-* support -device with
sysbus devices, and none of the devices above is supported with these
machines.

Set cannot_instantiate_with_device_add_yet to preserve our luck.

19f33f1689 hw: Mark device misusing nd_table[] FIXME
NICs defined with -net nic are for board initialization to wire up.
Board code examines nd_table[] to find them, and creates devices with
their qdev NIC properties set accordingly.

Except "allwinner-a10" goes on a fishing expedition for NIC
configuration instead of exposing the usual NIC properties for board
code to set: it uses nd_table[0] in its instance_init() method.

Picking up the first -net nic option's configuration that way works
when the device is created by board code.  But it's inappropriate for
-device and device_add.  Not only is it inconsistent with how the
other block device models work (they get their configuration from
properties "mac", "vlan", "netdev"), it breaks when nd_table[0] has
been picked up by the board or a previous -device / device_add
already.

Example:

    $ qemu-system-arm -S -M cubieboard -device allwinner-a10
    qemu-system-arm: -device allwinner-a10: Property 'allwinner-emac.netdev' can't take value 'hub0port0', it's in use
    Aborted (core dumped)

It also breaks in other entertaining ways:

    $ qemu-system-arm -M highbank -device allwinner-a10
    qemu-system-arm: -device allwinner-a10: Unsupported NIC model: xgmac
    $ qemu-system-arm -M highbank -net nic,model=allwinner-emac -device allwinner-a10
    qemu-system-arm: Unsupported NIC model: allwinner-emac

Mark the mistake with a FIXME comment.
