c4e2aff81b qemu-nbd: Look up flag names in array
The existing code to convert flag bits into strings looks a bit strange
now, and if we ever add more flags, it will look even stranger.  Prevent
that from happening by making it look up the flag names in an array.

/mnt/d/qemu/include/qemu/osdep.h:97:9: error: '__USE_MINGW_ANSI_STDIO' macro redefined [-Werror,-Wmacro-redefined]
 #define __USE_MINGW_ANSI_STDIO 1

It turns out that __USE_MINGW_ANSI_STDIO must be set before any
system headers are included, not just before stdio.h.

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]

                        virt_flash_create1() for flash[1]
                            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()
            ...
                property_set_alias() for machine props pflash0, pflash1
                    ...
                        set_drive() for cfi.pflash01 prop drive
                            this is how -machine pflash0=... etc set

ec132efaa8 spapr: Support NVIDIA V100 GPU with NVLink2
NVIDIA V100 GPUs have on-board RAM which is mapped into the host memory
space and accessible as normal RAM via an NVLink bus. The VFIO-PCI driver
implements special regions for such GPUs and emulates an NVLink bridge.
NVLink2-enabled POWER9 CPUs also provide address translation services
which includes an ATS shootdown (ATSD) register exported via the NVLink
bridge device.

This adds a quirk to VFIO to map the GPU memory and create an MR;
the new MR is stored in a PCI device as a QOM link. The sPAPR PCI uses
this to get the MR and map it to the system address space.
Another quirk does the same for ATSD.

This adds additional steps to sPAPR PHB setup:

1. Search for specific GPUs and NPUs, collect findings in
sPAPRPHBState::nvgpus, manage system address space mappings;

2. Add device-specific properties such as "ibm,npu", "ibm,gpu",
"memory-block", "link-speed" to advertise the NVLink2 function to
the guest;

3. Add "mmio-atsd" to vPHB to advertise the ATSD capability;

4. Add new memory blocks (with extra "linux,memory-usable" to prevent
the guest OS from accessing the new memory until it is onlined) and
npuphb# nodes representing an NPU unit for every vPHB as the GPU driver
uses it for link discovery.

This allocates space for GPU RAM and ATSD like we do for MMIOs by
adding 2 new parameters to the phb_placement() hook. Older machine types
set these to zero.

This puts new memory nodes in a separate NUMA node to as the GPU RAM
needs to be configured equally distant from any other node in the system.
Unlike the host setup which assigns numa ids from 255 downwards, this
adds new NUMA nodes after the user configures nodes or from 1 if none
were configured.

This adds requirement similar to EEH - one IOMMU group per vPHB.
The reason for this is that ATSD registers belong to a physical NPU
so they cannot invalidate translations on GPUs attached to another NPU.
It is guaranteed by the host platform as it does not mix NVLink bridges
or GPUs from different NPU in the same IOMMU group. If more than one
IOMMU group is detected on a vPHB, this disables ATSD support for that
vPHB and prints a warning.

905b7ee4d6 exec: Introduce qemu_maxrampagesize() and rename qemu_getrampagesize()
Rename qemu_getrampagesize() to qemu_minrampagesize(). While at it,
properly rename find_max_supported_pagesize() to
find_min_backend_pagesize().

s390x is actually interested into the maximum ram pagesize, so
introduce and use qemu_maxrampagesize().

Add a TODO, indicating that looking at any mapped memory backends is not
100% correct in some cases.

ede9a8a656 include: Move fprintf_function to disas/
The previous commits have eliminated fprintf_function outside
disassemblers, simplifying code and cleaning up the ugly type-punning
fprintf_function seems to attract.  Move fprintf_function to
include/disas/dis-asm.h to reduce the temptation to abuse it.

I considered renaming it to fprintf_ftype (reverting that part of
commit 6e2d864edf, v0.14.0) to get us closer to binutils, but I
figure the fork is too distant to make this worthwhile.

3979fca4b6 disas: Rename include/disas/bfd.h back to include/disas/dis-asm.h
Commit dc99065b5f (v0.1.0) added dis-asm.h from binutils.

Commit 43d4145a98 (v0.1.5) inlined bfd.h into dis-asm.h to remove the
dependency on binutils.

Commit 76cad71136 (v1.4.0) moved dis-asm.h to include/disas/bfd.h.
The new name is confusing when you try to match against (pre GPLv3+)
binutils.  Rename it back.  Keep it in the same directory, of course.

30cc98315f monitor: Clean up how monitor_disas() funnels output to monitor
INIT_DISASSEMBLE_INFO() takes an fprintf()-like callback and a FILE *
to pass to it.  monitor_disas() passes monitor_fprintf() and the
current monitor cast to FILE *.  monitor_fprintf() casts it right
back, and is otherwise identical to monitor_printf().  The

Pass qemu_fprintf() and NULL instead.

monitor_fprintf() is now unused; delete it.

90c84c5600 qom/cpu: Simplify how CPUClass:cpu_dump_state() prints
CPUClass method dump_statistics() takes an fprintf()-like callback and
a FILE * to pass to it.  Most callers pass fprintf() and stderr.
log_cpu_state() passes fprintf() and qemu_log_file.
hmp_info_registers() passes monitor_fprintf() and the current monitor
cast to FILE *.  monitor_fprintf() casts it right back, and is
otherwise identical to monitor_printf().

The callback gets passed around a lot, which is tiresome.  The
type-punning around monitor_fprintf() is ugly.

Drop the callback, and call qemu_fprintf() instead.  Also gets rid of
the type-punning, since qemu_fprintf() takes NULL instead of the
current monitor cast to FILE *.

19aaa4c3fd qemu-print: New qemu_fprintf(), qemu_vfprintf()
Code that doesn't want to know about current monitor vs. stdout
vs. stderr takes an fprintf_function callback and a FILE * argument to
pass to it.  Actual arguments are either fprintf() and stdout or
stderr, or monitor_fprintf() and the current monitor cast to FILE *.
monitor_fprintf() casts it right back, and is otherwise identical to
monitor_printf().  The type-punning is ugly.

New qemu_fprintf() and qemu_vprintf() address this need without type
punning: they are like fprintf() and vfprintf(), except they print to
the current monitor when passed a null FILE *.  The next commits will
put them to use.

0442428a89 target: Simplify how the TARGET_cpu_list() print
The various TARGET_cpu_list() take an fprintf()-like callback and a
FILE * to pass to it.  Their callers (vl.c's main() via list_cpus(),
bsd-user/main.c's main(), linux-user/main.c's main()) all pass
fprintf() and stdout.  Thus, the flexibility provided by the (rather
tiresome) indirection isn't actually used.

Drop the callback, and call qemu_printf() instead.

Calling printf() would also work, but would make the code unsuitable
for monitor context without making it simpler.

mtree_info() takes an fprintf()-like callback and a FILE * to pass to

Its only caller hmp_info_mtree() passes monitor_printf() cast to

The type-punning is technically undefined behaviour, but works in
practice.  Clean up: drop the callback, and call qemu_printf()
