Cornelia Huck 9aec2e52ce hw: add compat machines for 4.2
Add 4.2 machine types for arm/i440fx/q35/s390x/spapr.

For i440fx and q35, unversioned cpu models are still translated
to -v1, as 0788a56bd1 ("i386: Make unversioned CPU models be
aliases") states this should only transition to the latest cpu
model version in 4.3 (or later).

Markus Armbruster 54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

Markus Armbruster 46517dd497 Include sysemu/sysemu.h a lot less
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

hw/qdev-core.h includes sysemu/sysemu.h since recent commit e965ffa70a
"qdev: add qdev_add_vm_change_state_handler()".  This is a bad idea:
hw/qdev-core.h is widely included.

Move the declaration of qdev_add_vm_change_state_handler() to
sysemu/sysemu.h, and drop the problematic include from hw/qdev-core.h.

Touching sysemu/sysemu.h now recompiles some 1800 objects.
qemu/uuid.h also drops from 5400 to 1800.  A few more headers show
smaller improvement: qemu/notify.h drops from 5600 to 5200,
qemu/timer.h from 5600 to 4500, and qapi/qapi-types-run-state.h from
5500 to 5000.

Markus Armbruster d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h.  Include hw/qdev-core.h there
instead.

hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

Peter Maydell 67505c114e hw/arm/boot: Further improve initrd positioning code
In commit e6b2b20d97 we made the boot loader code try to avoid
putting the initrd on top of the kernel.  However the expression used
to calculate the start of the initrd:

    info->initrd_start = info->loader_start +
        MAX(MIN(info->ram_size / 2, 128 * 1024 * 1024), kernel_size);

incorrectly uses 'kernel_size' as the offset within RAM of the
highest address to avoid.  This is incorrect because the kernel
doesn't start at address 0, but slightly higher than that.  This
means that we can still incorrectly end up overlaying the initrd on
the kernel in some cases, for example:

* The kernel's image_size is 0x0a7a8000
* The kernel was loaded at   0x40080000
* The end of the kernel is   0x4A828000
* The DTB was loaded at      0x4a800000

To get this right we need to track the actual highest address used
by the kernel and use that rather than kernel_size. We already
set image_low_addr and image_high_addr for ELF images; set them
also for the various other image types we support, and then use
image_high_addr as the lowest allowed address for the initrd.
(We don't use image_low_addr, but we set it for consistency
with the existing code path for ELF files.)

Peter Maydell c8ead57124 hw/arm/sbsa-ref: Remove unnecessary check for secure_sysmem == NULL
In the virt machine, we support TrustZone being either present or
absent, and so the code must deal with the secure_sysmem pointer
possibly being NULL. In the sbsa-ref machine, TrustZone is always
present, but some code and comments copied from virt still treat
it as possibly not being present.

This causes Coverity to complain (CID 1407287) that we check
secure_sysmem for being NULL after an unconditional dereference.
Simplify the code so that instead of initializing the variable
to NULL, unconditionally assigning it, and then testing it for NULL,
we just initialize it correctly in the variable declaration and
then assume it to be non-NULL. We also delete a comment which
only applied to the non-TrustZone config.

Igor Mammedov cd5ff8333a machine: show if CLI option '-numa node,mem' is supported in QAPI schema
Legacy '-numa node,mem' option has a number of issues and mgmt often
defaults to it. Unfortunately it's no possible to replace it with
an alternative '-numa memdev' without breaking migration compatibility.
What's possible though is to deprecate it, keeping option working with
old machine types only.

In order to help users to find out if being deprecated CLI option
'-numa node,mem' is still supported by particular machine type, add new
"numa-mem-supported" property to output of query-machines.

"numa-mem-supported" is set to 'true' for machines that currently support
NUMA, but it will be flipped to 'false' later on, once deprecation period
expires and kept 'true' only for old machine types that used to support
the legacy option so it won't break existing configuration that are using
it.

Hongbo Zhang 64580903c2 hw/arm: Add arm SBSA reference machine, skeleton part
For AArch64, the existing "virt" machine is primarily meant to
run on KVM and execute virtualization workloads, but we need an
environment as faithful as possible to physical hardware, for supporting
firmware and OS development for physical Aarch64 machines.

This patch introduces new machine type 'sbsa-ref' with main features:
 - Based on 'virt' machine type.
 - A new memory map.
 - CPU type cortex-a57.
 - EL2 and EL3 are enabled.
 - GIC version 3.
 - System bus AHCI controller.
 - System bus EHCI controller.
 - CDROM and hard disc on AHCI bus.
 - E1000E ethernet card on PCIE bus.
 - VGA display adaptor on PCIE bus.
 - No virtio devices.
 - No fw_cfg device.
 - No ACPI table supplied.
 - Only minimal device tree nodes.

Arm Trusted Firmware and UEFI porting to this are done accordingly,
and the firmware should supply ACPI tables to the guest OS.  The
minimal device tree nodes supplied by QEMU for this platform are only
to pass the dynamic info reflecting command line input to firmware,
not for loading the guest OS.

To make the review easier, this task is split into two patches, the
fundamental skeleton part and the peripheral devices part; this patch is
the first part.

watchdog to expire. Therefore, we need the watchdog to be able to
access the SCU's register space.

This causes the watchdog to not perform a system reset when the bit is
set. In the future it could perform a reset of the SDMC model.

The XDMA engine embedded in the Aspeed SOCs performs PCI DMA operations
between the SOC (acting as a BMC) and a host processor in a server.

The XDMA engine exists on the AST2400, AST2500, and AST2600 SOCs, so
enable it for all of those. Add trace events on the important register
writes in the XDMA engine.

Cédric Le Goater ad1a978218 aspeed: add a RAM memory region container
The RAM memory region is defined after the SoC is realized when the
SDMC controller has checked that the defined RAM size for the machine
is correct. This is problematic for controller models requiring a link
on the RAM region, for DMA support in the SMC controller for instance.

Introduce a container memory region for the RAM that we can link into
the controllers early, before the SoC is realized. It will be
populated with the RAM region after the checks have be done.

Cédric Le Goater ece09beec4 aspeed: introduce a configurable number of CPU per machine
The current models of the Aspeed SoCs only have one CPU but future
ones will support SMP. Introduce a new num_cpus field at the SoC class
level to define the number of available CPUs per SoC and also
introduce a 'num-cpus' property to activate the CPUs configured for
the machine.

The max_cpus limit of the machine should depend on the SoC definition
but, unfortunately, these values are not available when the machine
class is initialized. This is the reason why we add a check on
num_cpus in the AspeedSoC realize handler.

SMP support will be activated when models for such SoCs are implemented.

Peter Maydell a90a862b9e hw/arm: Correctly disable FPU/DSP for some ARMSSE-based boards
The SSE-200 hardware has configurable integration settings which
determine whether its two CPUs have the FPU and DSP:
 * CPU0_FPU (default 0)
 * CPU0_DSP (default 0)
 * CPU1_FPU (default 1)
 * CPU1_DSP (default 1)

Similarly, the IoTKit has settings for its single CPU:
 * CPU0_FPU (default 1)
 * CPU0_DSP (default 1)

Of our four boards that use either the IoTKit or the SSE-200:
 * mps2-an505, mps2-an521 and musca-a use the default settings
 * musca-b1 enables FPU and DSP on both CPUs

Currently QEMU models all these boards using CPUs with
both FPU and DSP enabled. This means that we are incorrect
for mps2-an521 and musca-a, which should not have FPU or DSP
on CPU0.

Create QOM properties on the ARMSSE devices corresponding to the
default h/w integration settings, and make the Musca-B1 board
enable FPU and DSP on both CPUs. This fixes the mps2-an521
and musca-a behaviour, and leaves the musca-b1 and mps2-an505
behaviour unchanged.

Peter Maydell 5e6dbe1e8c hw/arm/boot: Honour image size field in AArch64 Image format kernels
Since Linux v3.17, the kernel's Image header includes a field image_size,
which gives the total size of the kernel including unpopulated data
sections such as the BSS). If this is present, then return it from
load_aarch64_image() as the true size of the kernel rather than
just using the size of the Image file itself. This allows the code
which calculates where to put the initrd to avoid putting it in
the kernel's BSS area.

This means that we should be able to reliably load kernel images
which are larger than 128MB without accidentally putting the
initrd or dtb in locations that clash with the kernel itself.

Peter Maydell e6b2b20d97 hw/arm/boot: Avoid placing the initrd on top of the kernel
We currently put the initrd at the smaller of:
 * 128MB into RAM
 * halfway into the RAM
(with the dtb following it).

However for large kernels this might mean that the kernel
overlaps the initrd. For some kinds of kernel (self-decompressing
32-bit kernels, and ELF images with a BSS section at the end)
we don't know the exact size, but even there we have a
minimum size. Put the initrd at least further into RAM than
that. For image formats that can give us an exact kernel size, this
will mean that we definitely avoid overlaying kernel and initrd.

incorrect assumption that info->ram_size can be treated as the

This is wrong, because many Arm boards (including "virt") specify

starts at a non-zero physical address.
