linux-user: Add strace support for printing arguments of ioctl()
This patch implements functionality for strace argument printing for ioctls.
When running ioctls through qemu with "-strace", they get printed in format:
"ioctl(fd_num,0x*,0x*) = ret_value"
where the request code an the ioctl's third argument get printed in a hexadicemal
format. This patch changes that by enabling strace to print both the request code
name and the contents of the third argument. For example, when running ioctl
RTC_SET_TIME with "-strace", with changes from this patch, it gets printed in
this way:
"ioctl(3,RTC_SET_TIME,{12,13,15,20,10,119,0,0,0}) = 0"
In case of IOC_R type ioctls, the contents of the third argument get printed
after the return value, and the argument inside the ioctl call gets printed
as pointer in hexadecimal format. For example, when running RTC_RD_TIME with
"-strace", with changes from this patch, it gets printed in this way:
"ioctl(3,RTC_RD_TIME,0x40800374) = 0 ({22,9,13,11,5,120,0,0,0})"
In case of IOC_RW type ioctls, the contents of the third argument get printed
both inside the ioctl call and after the return value.
Implementation notes:
Functions "print_ioctl()" and "print_syscall_ret_ioctl()", that are defined
in "strace.c", are listed in file "strace.list" as "call" and "result"
value for ioctl. Structure definition "IOCTLEntry" as well as predefined
values for IOC_R, IOC_W and IOC_RW were cut and pasted from file "syscall.c"
to file "qemu.h" so that they can be used by these functions to print the
contents of the third ioctl argument. Also, the "static" identifier for array
"ioctl_entries[]" was removed and this array was declared as "extern" in "qemu.h"
so that it can also be used by these functions. To decode the structure type
of the ioctl third argument, function "thunk_print()" was defined in file
"thunk.c" and its definition is somewhat simillar to that of function
"thunk_convert()".

Replace uses of FROM_SSI_SLAVE() macro with QOM casts
The FROM_SSI_SLAVE() macro predates QOM and is used as a typesafe way
to cast from an SSISlave* to the instance struct of a subtype of
TYPE_SSI_SLAVE. Switch to using the QOM cast macros instead, which
have the same effect (by writing the QOM macros if the types were
previously missing them.)
(The FROM_SSI_SLAVE() macro allows the SSISlave member of the
subtype's struct to be anywhere as long as it is named "ssidev",
whereas a QOM cast macro insists that it is the first thing in the
subtype's struct. This is true for all the types we convert here.)
This removes all the uses of FROM_SSI_SLAVE() so we can delete the

usual QOM TYPE and casting macros; provide and use them.
In particular, we can safely use the QOM cast macros instead of
FROM_SSI_SLAVE() because in both cases the 'ssidev' field of
the instance state struct is the first field in it.

hw/arm/spitz: Encapsulate misc GPIO handling in a device
Currently we have a free-floating set of IRQs and a function
spitz_out_switch() which handle some miscellaneous GPIO lines for the
spitz board. Encapsulate this behaviour in a simple QOM device.
At this point we can finally remove the 'max1111' global, because the
ADC battery-temperature value is now handled by the misc-gpio device
writing the value to its outbound "adc-temp" GPIO, which the board
code wires up to the appropriate inbound GPIO line on the max1111.
This commit also fixes Coverity issue CID

that the 'outsignals' in spitz_scoop_gpio_setup() were leaked),

hw/arm/virt-acpi-build: Only expose flash on older machine types
The flash device is exclusively for the host-controlled firmware, so
we should not expose it to the OS. Exposing it risks the OS messing
with it, which could break firmware runtime services and surprise the
OS when all its changes disappear after reboot.
As firmware needs the device and uses DT, we leave the device exposed
there. It's up to firmware to remove the nodes from DT before sending
it on to the OS. However, there's no need to force firmware to remove
tables from ACPI (which it doesn't know how to do anyway), so we
simply don't add the tables in the first place. But, as we've been
adding the tables for quite some time and don't want to change the
default hardware exposed to versioned machines, then we only stop
exposing the flash device tables for 5.1 and later machine types.

This patch implements the PROBE request. At the moment,
only THE RESV_MEM property is handled. The first goal is
to report iommu wide reserved regions such as the MSI regions
set by the machine code. On x86 this will be the IOAPIC MSI
region, [0xFEE00000 - 0xFEEFFFFF], on ARM this may be the ITS
doorbell.
In the future we may introduce per device reserved regions.
This will be useful when protecting host assigned devices
which may expose their own reserved regions

qdev: Introduce DEFINE_PROP_RESERVED_REGION
Introduce a new property defining a reserved region:
<low address>:<high address>:<type>.
This will be used to encode reserved IOVA regions.
For instance, in virtio-iommu use case, reserved IOVA regions
will be passed by the machine code to the virtio-iommu-pci
device (an array of those). The type of the reserved region
will match the virtio_iommu_probe_resv_mem subtype value:
- VIRTIO_IOMMU_RESV_MEM_T_RESERVED (0)
- VIRTIO_IOMMU_RESV_MEM_T_MSI (1)
on PC/Q35 machine, this will be used to inform the
virtio-iommu-pci device it should bypass the MSI region.
The reserved region will be: 0xfee00000:0xfeefffff:1.
On ARM, we can declare the ITS MSI doorbell as an MSI
region to prevent MSIs from being mapped on guest side.

It also contains one patch that fixes CLINT accesses for RISC-V. This
fixes a regression for most RISC-V boards.
The rest of the PR is adding support for the v0.7.1 RISC-V vector

still in a draft state.
This is a v2 pull request that has fixed the building on big endian

numa: Auto-enable NUMA when any memory devices are possible
Let's auto-enable it also when maxmem is specified but no slots are
defined. This will result in us properly creating ACPI srat tables,
indicating the maximum possible PFN to the guest OS. Based on this, e.g.,
Linux will enable the swiotlb properly.
This avoids having to manually force the switolb on (swiotlb=force) in
Linux in case we're booting only using DMA memory (e.g., 2GB on x86-64),
and virtio-mem adds memory later on that really needs the swiotlb to be
used for DMA.
Let's take care of backwards compatibility if somebody has a setup that
specifies "maxram" without "slots".

Let's register the notifier and trigger the qapi event with the right
device id.
MEMORY_DEVICE_SIZE_CHANGE is similar to BALLOON_CHANGE, however on a
memory device level.
Don't unregister the notifier (we neither have finalize() nor unrealize()
for VirtIOPCIProxy, so it's not that simple to do it) - both devices are
expected to vanish at the same time.

virtio-mem: Allow notifiers for size changes
We want to send qapi events in case the size of a virtio-mem device
changes. This allows upper layers to always know how much memory is
actually currently consumed via a virtio-mem device.
Unfortuantely, we have to report the id of our proxy device. Let's provide
an easy way for our proxy device to register, so it can send the qapi
events. Piggy-backing on the notifier infrastructure (although we'll
only ever have one notifier registered) seems to be an easy way.

virtio-mem: Paravirtualized memory hot(un)plug
This is the very basic/initial version of virtio-mem. An introduction to
virtio-mem can be found in the Linux kernel driver [1]. While it can be
used in the current state for hotplug of a smaller amount of memory, it
will heavily benefit from resizeable memory regions in the future.
Each virtio-mem device manages a memory region (provided via a memory
backend). After requested by the hypervisor ("requested-size"), the
guest can try to plug/unplug blocks of memory within that region, in order
to reach the requested size. Initially, and after a reboot, all memory is
unplugged (except in special cases - reboot during postcopy).
The guest may only try to plug/unplug blocks of memory within the usable
region size. The usable region size is a little bigger than the
requested size, to give the device driver some flexibility. The usable
region size will only grow, except on reboots or when all memory is
requested to get unplugged. The guest can never plug more memory than
requested. Unplugged memory will get zapped/discarded, similar to in a
balloon device.
The block size is variable, however, it is always chosen in a way such that
THP splits are avoided (e.g., 2MB). The state of each block
(plugged/unplugged) is tracked in a bitmap.
As virtio-mem devices (e.g., virtio-mem-pci) will be memory devices, we now
expose "VirtioMEMDeviceInfo" via "query-memory-devices".
--------------------------------------------------------------------------
There are two important follow-up items that are in the works:
1. Resizeable memory regions: Use resizeable allocations/RAM blocks to
grow/shrink along with the usable region size. This avoids creating
initially very big VMAs, RAM blocks, and KVM slots.
2. Protection of unplugged memory: Make sure the gust cannot actually
make use of unplugged memory.
Other follow-up items that are in the works:
1. Exclude unplugged memory during migration (via precopy notifier).
2. Handle remapping of memory.
3. Support for other architectures.
--------------------------------------------------------------------------
Example usage (virtio-mem-pci is introduced in follow-up patches):
Start QEMU with two virtio-mem devices (one per NUMA node):
$ qemu-system-x86_64 -m 4G,maxmem=20G \
-smp sockets=2,cores=2 \
-numa node,nodeid=0,cpus=0-1 -numa node,nodeid=1,cpus=2-3 \
[...]
-object memory-backend-ram,id=mem0,size=8G \
-device virtio-mem-pci,id=vm0,memdev=mem0,node=0,requested-size=0M \
-object memory-backend-ram,id=mem1,size=8G \
-device virtio-mem-pci,id=vm1,memdev=mem1,node=1,requested-size=1G

qemu-img convert: Don't pre-zero images
Since commit
5a37b60a61c, qemu-img create will pre-zero the target image
if it isn't already zero-initialised (most importantly, for host block
devices, but also iscsi etc.), so that writing explicit zeros wouldn't
be necessary later.
This could speed up the operation significantly, in particular when the
source image file was only sparsely populated. However, it also means
that some block are written twice: Once when pre-zeroing them, and then
when they are overwritten with actual data. On a full image, the
pre-zeroing is wasted work because everything will be overwritten.
In practice, write_zeroes typically turns out faster than writing
explicit zero buffers, but slow enough that first zeroing everything and
then overwriting parts can be a significant net loss.
Meanwhile, qemu-img convert was rewritten in
690c7301600 and zero blocks
are now written to the target using bdrv_co_pwrite_zeroes() if the
target could be pre-zeroed. This way we already make use of the faster
write_zeroes operation, but avoid writing any blocks twice.
Remove the pre-zeroing because these days this former optimisation has
actually turned into a pessimisation in the common case.
