Eric Auger c294ac327c hw/arm/virt: vTPM support
Let the TPM TIS SYSBUS device be dynamically instantiable
in ARM virt.  A device tree node is dynamically created
(TPM via MMIO).

The TPM Physical Presence interface (PPI) is not supported.

To run with the swtmp TPM emulator, the qemu command line must
be augmented with:

        -chardev socket,id=chrtpm,path=swtpm-sock \
        -tpmdev emulator,id=tpm0,chardev=chrtpm \
        -device tpm-tis-device,tpmdev=tpm0 \

swtpm/libtpms command line example:

swtpm socket --tpm2 -t -d --tpmstate dir=/tmp/tpm \
--ctrl type=unixio,path=swtpm-sock

Eric Auger 70e89132c9 hw/arm/virt: Add the virtio-iommu device tree mappings
Adds the "virtio,pci-iommu" node in the host bridge node and
the RID mapping, excluding the IOMMU RID.

This is done in the virtio-iommu-pci hotplug handler which
gets called only if no firmware is loaded or if -no-acpi is
passed on the command line. As non DT integration is
not yet supported by the kernel we must make sure we
are in DT mode. This limitation will be removed as soon
as the topology description feature gets supported.

Evgeny Yakovlev 5f2585772f virtio-blk: advertise F_WCE (F_FLUSH) if F_CONFIG_WCE is advertised
Virtio spec 1.1 (and earlier), 5.2.5.2 Driver Requirements: Device
Initialization:

"Devices SHOULD always offer VIRTIO_BLK_F_FLUSH, and MUST offer it if
they offer VIRTIO_BLK_F_CONFIG_WCE"

Currently F_CONFIG_WCE and F_WCE are not connected to each other.
Qemu will advertise F_CONFIG_WCE if config-wce argument is
set for virtio-blk device. And F_WCE is advertised only if
underlying block backend actually has it's caching enabled.

Fix this by advertising F_WCE if F_CONFIG_WCE is also advertised.

To preserve backwards compatibility with newer machine types make this
behaviour governed by "x-enable-wce-if-config-wce" virtio-blk-device
property and introduce hw_compat_4_2 with new property being off by
default for all machine types <= 4.2 (but don't introduce 4.3
machine type itself yet).

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.

David Engraf 80734cbdca hw/arm/virt: Fix non-secure flash mode
Using the whole 128 MiB flash in non-secure mode is not working because
virt_flash_fdt() expects the same address for secure_sysmem and sysmem.
This is not correctly handled by caller because it forwards NULL for
secure_sysmem in non-secure flash mode.

Fixed by using sysmem when secure_sysmem is NULL.

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.

Markus Armbruster e0561e60f1 hw/arm/virt: Support firmware configuration with -blockdev
The ARM virt machines put firmware in flash memory.  To configure it,
you use -drive if=pflash,unit=0,... and optionally -drive
if=pflash,unit=1,...

Why two -drive?  This permits setting up one part of the flash memory
read-only, and the other part read/write.  It also makes upgrading
firmware on the host easier.  Below the hood, we get two separate
flash devices, because we were too lazy to improve our flash device
models to support sector protection.

The problem at hand is to do the same with -blockdev somehow, as one
more step towards deprecating -drive.

We recently solved this problem for x86 PC machines, in commit
ebc29e1bea.  See the commit message for design rationale.

This commit solves it for ARM virt basically the same way: new machine
properties pflash0, pflash1 forward to the onboard flash devices'
properties.  Requires creating the onboard devices in the
.instance_init() method virt_instance_init().  The existing code to
pick up drives defined with -drive if=pflash is replaced by code to
desugar into the machine properties.

There are a few behavioral differences, though:

* The flash devices are always present (x86: only present if
  configured)

* Flash base addresses and sizes are fixed (x86: sizes depend on
  images, mapped back to back below a fixed address)

* -bios configures contents of first pflash (x86: -bios configures ROM
   contents)

* -bios is rejected when first pflash is also configured with -machine
   pflash0=... (x86: bios is silently ignored then)

* -machine pflash1=... does not require -machine pflash0=... (x86: it
   does).

The actual code is a bit simpler than for x86 mostly due to the first
two differences.

Before the patch, all the action is in create_flash(), called from the
machine's .init() method machvirt_init():

    main()
        machine_run_board_init()
            machvirt_init()
                create_flash()
                    create_one_flash() for flash[0]
                        create
                        configure
                            includes obeying -drive if=pflash,unit=0
                        realize
                        map
                        fall back to -bios
                    create_one_flash() for flash[1]
                        create
                        configure
                            includes obeying -drive if=pflash,unit=1
                        realize
                        map
                    update FDT

To make the machine properties work, we need to move device creation
to its .instance_init() method virt_instance_init().

Another complication is machvirt_init()'s computation of
@firmware_loaded: it predicts what create_flash() will do.  Instead of
predicting what create_flash()'s replacement virt_firmware_init() will
do, I decided to have virt_firmware_init() return what it did.
Requires calling it a bit earlier.

Resulting call tree:

    main()
        current_machine = object_new()
            ...
                virt_instance_init()
                    virt_flash_create()
                        virt_flash_create1() for flash[0]
                            create

                            configure: set defaults
                            become child of machine [NEW]
                            add machine prop pflash1 as alias for drive [NEW]
        for all machine props from the command line: machine_set_property()

Eric Auger 50a17297e2 hw/arm/virt: Bump the 255GB initial RAM limit
Now we have the extended memory map (high IO regions beyond the
scalable RAM) and dynamic IPA range support at KVM/ARM level
we can bump the legacy 255GB initial RAM limit. The actual maximum
RAM size now depends on the physical CPU and host kernel, in
accelerated mode. In TCG mode, it depends on the VCPU
AA64MMFR0.PARANGE.

Eric Auger 2ba956ccfa hw/arm/virt: Check the VCPU PA range in TCG mode
We are about to allow the memory map to grow beyond 1TB and
potentially overshoot the VCPU AA64MMFR0.PARANGE.

In aarch64 mode and when highmem is set, let's check the VCPU
PA range is sufficient to address the highest GPA of the memory
map.

Eric Auger c9650222b8 hw/arm/virt: Implement kvm_type function for 4.0 machine
This patch implements the machine class kvm_type() callback.
It returns the number of bits requested to implement the whole GPA
range including the RAM and IO regions located beyond.
The returned value is passed though the KVM_CREATE_VM ioctl and
this allows KVM to set the stage2 tables dynamically.

To compute the highest GPA used in the memory map, kvm_type()
must freeze the memory map by calling virt_set_memmap().

Eric Auger 957e32cffa hw/arm/virt: Dynamic memory map depending on RAM requirements
Up to now the memory map has been static and the high IO region
base has always been 256GiB.

This patch modifies the virt_set_memmap() function, which freezes
the memory map, so that the high IO range base becomes floating,
located after the initial RAM and the device memory.

The function computes
- the base of the device memory,
- the size of the device memory,
- the high IO region base
- the highest GPA used in the memory map.

Entries of the high IO region are assigned a base address. The
device memory is initialized.

The highest GPA used in the memory map will be used at VM creation
to choose the requested IPA size.

Setting all the existing highmem IO regions beyond the RAM
allows to have a single contiguous RAM region (initial RAM and
possible hotpluggable device memory). That way we do not need
to do invasive changes in the EDK2 FW to support a dynamic
RAM base.

Still the user cannot request an initial RAM size greater than 255GB.

Eric Auger 350a9c9e18 hw/arm/virt: Split the memory map description
In the prospect to introduce an extended memory map supporting more
RAM, let's split the memory map array into two parts:

- the former a15memmap, renamed base_memmap, contains regions below
  and including the RAM. MemMapEntries initialized in this array
  have a static size and base address.
- extended_memmap, only initialized with entries located after the
  RAM. MemMapEntries initialized in this array only get their size
  initialized. Their base address is dynamically computed depending
  on the the top of the RAM, with same alignment as their size.

Eventually base_memmap entries are copied into the extended_memmap
array. Using two separate arrays however clarifies which entries
are statically allocated and those which are dynamically allocated.

This new split will allow to grow the RAM size without changing the
description of the high IO entries.

We introduce a new virt_set_memmap() helper function which
"freezes" the memory map. We call it in machvirt_init as
memory attributes of the machine are not yet set when
virt_instance_init() gets called.

The memory map is unchanged (the top of the initial RAM still is
256GiB). Then come the high IO regions with same layout as before.

Peter Maydell 846690dee8 virt: Suppress external aborts on virt-2.10 and earlier
In commit c79c0a314c we enabled emulation of external aborts
when the guest attempts to access a physical address with no
mapped device. In commit 4672cbd7be we suppress this for
most legacy boards to prevent breakage of previously working
guests, but we didn't suppress it in the 'virt' board, with
the rationale "we know that guests won't try to prod devices
that we don't describe in the device tree or ACPI tables". This
is mostly true, but we've had a report of a Linux guest image
that this did break. The problem seems to be that the guest
is (incorrectly) configured with a DEBUG_UART_PHYS value that
tells it there is a uart at 0x10009000 (which is true for
vexpress but not for virt), so in early bootup the kernel
probes this bogus address.

This is a misconfigured guest, so we don't need to worry
about it too much, but we can arrange that guests that ran
on QEMU v2.10 (before c79c0a314c) will still run on
the "virt-2.10" board model, by suppressing external aborts
only for that version and earlier. This seems a reasonable
compromise: "virt-2.10" is supposed to behave the same way
that "virt" did in the 2.10 release, and making it do that
provides a usable workaround for guests with bugs like this.

512 redistributors can fit in this latter on top of the 123 allowed
by the legacy redistributor region.

Registering this second redistributor region is possible if the
host kernel supports the following VGICv3 KVM device group/attribute:
KVM_DEV_ARM_VGIC_GRP_ADDR/KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION.

In case the host kernel does not support the registration of several
redistributor regions and the requested number of vcpus exceeds the
capacity of the legacy redistributor region, the GICv3 device
initialization fails with a proper error message and qemu exits.

At the moment the max number of vcpus still is capped by the
virt machine class max_cpus.

Eric Auger f90747c4e8 hw/arm/virt: GICv3 DT node with one or two redistributor regions
This patch allows the creation of a GICv3 node with 1 or 2
redistributor regions depending on the number of smu_cpus.
The second redistributor region is located just after the
existing RAM region, at 256GB and contains up to up to 512 vcpus.

Eric Auger 1e575b6664 hw/intc/arm_gicv3: Introduce redist-region-count array property
To prepare for multiple redistributor regions, we introduce
an array of uint32_t properties that stores the redistributor
count of each redistributor region.

Non accelerated VGICv3 only supports a single redistributor region.
The capacity of all redist regions is checked against the number of
vcpus.

Machvirt is updated to set those properties, ie. a single
redistributor region with count set to the number of vcpus
capped by 123.

To make it work for migrating old version QEMU to 2.13 QEMU, we

destination which is the default behavior of the machine type
which is older than 2.13, alternately, the strict check can be

Igor Mammedov 3b77f6c353 arm/boot: split load_dtb() from arm_load_kernel()
load_dtb() depends on arm_load_kernel() to figure out place
in RAM where it should be loaded, but it's not required for
arm_load_kernel() to work. Sometimes it's neccesary for
devices added with -device/device_add to be enumerated in
DTB as well, which's lead to [1] and surrounding commits to
add 2 more machine_done notifiers with non obvious ordering
to make dynamic sysbus devices initialization happen in
the right order.

However instead of moving whole arm_load_kernel() in to
machine_done, it's sufficient to move only load_dtb() into
virt_machine_done() notifier and remove ArmLoadKernelNotifier/
/PlatformBusFDTNotifierParams notifiers, which saves us ~90LOC
and simplifies code flow quite a bit.
Later would allow to consolidate DTB generation within one
function for 'mach-virt' board and make it reentrant so it
could generate updated DTB in device hotplug secenarios.

While at it rename load_dtb() to arm_load_dtb() since it's
public now.

Add additional field skip_dtb_autoload to struct arm_boot_info
to allow manual DTB load later in mach-virt and to avoid touching
all other boards to explicitly call arm_load_dtb().

Igor Mammedov a3fc839635 platform-bus-device: use device plug callback instead of machine_done notifier
platform-bus were using machine_done notifier to get and map
(assign irq/mmio resources) dynamically added sysbus devices
after all '-device' options had been processed.
That however creates non obvious dependencies on ordering of
machine_done notifiers and requires carefull line juggling
to keep it working. For example see comment above
create_platform_bus() and 'straitforward' arm_load_kernel()
had to converted to machine_done notifier and that lead to
yet another machine_done notifier to keep it working
arm_register_platform_bus_fdt_creator().

Instead of hiding resource assignment in platform-bus-device
to magically initialize sysbus devices, use device plug
callback and assign resources explicitly at board level
at the moment each -device option is being processed.

That adds a bunch of machine declaration boiler plate to
e500plat board, similar to ARM/x86 but gets rid of hidden
machine_done notifier and would allow to remove the dependent
notifiers in ARM code simplifying it and making code flow
easier to follow.

This allows to pin the host controller in the Linux PCI domain space.
Linux requires that property to be available consistently or not at all,
in which case the domain number becomes unstable on additions/removals.
Adding it here won't make a difference in practice for most setups as we
only expose one controller.

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

Add support for passing 'max' to -machine gic-version. By analogy
with the -cpu max option, this picks the "best available" GIC version
whether you're using KVM or TCG, so it behaves like 'host' when
using KVM, and gives you GICv3 when using TCG.

Also like '-cpu host', using -machine gic-version=max' means there
is no guarantee of migration compatibility between QEMU versions;
in future 'max' might mean '4'.
