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.

Rename all the variables which used to be VirtBoardInfo*
and are now VirtMachineState* so their names are in line
with the type being used.
Apart from the removal of the line 'VirtMachineState *vbi = vms;'
this commit is purely a search-and-replace of 'vbi' with 'vms'.

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.

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.

CPU vPMU is now turned ON by default, but this feature wasn't introduced
until virt-2.7 machine type. To solve this problem, this patch adds a
PMU option in machine state, which is used to control CPU's vPMU status.
This PMU option is not exposed to command line and is turned off in
virt-2.6 machine type.

This patch adds a pmu=[on/off] option to enable/disable vPMU support
in guest vCPU. It allows virt tools, such as libvirt, to determine the
exsitence of vPMU and configure it. Note this option is only available
for cortex-a57/cortex-53/ host CPUs, but unavailable on ARMv7 and other
processors. Also even though "pmu=" option is available for TCG mode,
setting it doesn't turn PMU on.

set minimum_page_bits accordingly, for improved performance.
Note that this is a migration compatibility break, so

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.

Considering that features are converted to global properties and
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.

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
bc64b96c984abf).

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.

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.

This is a breaking change, but I don't expect it to be noticed

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.

as the one there was already correctly checking max-cpus instead
of smp-cpus.

The virt board has an arch timer, which is always on. Emit the
"always-on" property to indicate to Linux that it can switch off the
periodic timer and reduces the amount of interrupts injected into a
guest.

Add a secure memory region to the virt board, which is the
same as the nonsecure memory region except that it also has
a secure-only UART in it. This is only created if the
board is started with the '-machine secure=on' property.

Wire up the system memory region to the CPUs explicitly
by setting the QOM property. This doesn't change anything
over letting it default, but will be needed for adding
a secure memory region later.

Clean up includes so that osdep.h is included first and headers

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.

Support the legacy -nic syntax for creating PCI network devices
as well as the new-style -device options. This makes life easier
for people moving from x86 KVM virtualization to ARM KVM virtualization
and expecting their network configuration options to work the same
way for both setups.
We use "virtio" as the default NIC model if the user doesn't specify one.

Currently mach-virt model doesn't support powerdown request. Guest VM
doesn't react to system_powerdown from monitor console (or QMP) because
there is no communication mechanism for such requests. This patch registers
GPIO Pin 3 with powerdown notification. So guest VM can receive notification
when such powerdown request is triggered.

ACPI 5.0 supports GPIO-signaled ACPI Events. This can be used for
powerdown, hotplug evnets. Add a GPIO controller in machine virt,
to support powerdown, maybe can be used for cpu hotplug. And
here we use pl061.
