4d63ef20cf hw/core/register: Add more 64-bit utilities
We already have some utilities to handle 64-bit wide registers, so this just
adds some more for:
- Initializing 64-bit registers
- Extracting and depositing to an array of 64-bit registers

4dc06bb816 hw/intc/sifive_clint: Fix muldiv64 overflow in sifive_clint_write_timecmp()
`muldiv64` would overflow in cases where the final 96-bit value does not
fit in a `uint64_t`. This would result in small values that cause an
interrupt to be triggered much sooner than intended.

The overflow can be detected in most cases by checking if the new value is
smaller than the previous value. If the final result is larger than
`diff` it is either correct or it doesn't matter as it is effectively
infinite anyways.

`next` is an `uint64_t` value, but `timer_mod` takes an `int64_t`. This
resulted in high values such as `UINT64_MAX` being converted to `-1`,
which caused an immediate timer interrupt.

By limiting `next` to `INT64_MAX` no overflow will happen while the
timer will still be effectively set to "infinitely" far in the future.

33fcedfac8 hw/riscv/virt.c: Assemble plic_hart_config string with g_strjoinv()
In the riscv virt machine init function, We assemble a string
plic_hart_config which is a comma-separated list of N copies of the
VIRT_PLIC_HART_CONFIG string.  The code that does this has a
misunderstanding of the strncat() length argument.  If the source
string is too large strncat() will write a maximum of length+1 bytes
(length bytes from the source string plus a trailing NUL), but the
code here assumes that it will write only length bytes at most.

This isn't an actual bug because the code has correctly precalculated
the amount of memory it needs to allocate so that it will never be
too small (i.e.  we could have used plain old strcat()), but it does
mean that the code looks like it has a guard against accidental
overrun when it doesn't.

Rewrite the string handling here to use the glib g_strjoinv()
function, which means we don't need to do careful accountancy of
string lengths, and makes it clearer that what we're doing is
"create a comma-separated string".

First ppc pull request for qemu-6.2.  As usual, there's a fair bit
 here, since it's been queued during the 6.1 freeze.  Highlights are:
 
  * Some fixes for 128 bit arithmetic and some vector opcodes that use
    them
  * Significant improvements to the powernv to support POWER10 cpus
    (more to come though)
  * Several cleanups to the ppc softmmu code

ab17a3fe74 ppc/pnv: Use a simple incrementing index for the chip-id
When the QEMU PowerNV machine was introduced, multi chip support
modeled a two socket system with dual chip modules as found on some P8
Tuleta systems (8286-42A). But this is hardly used and not relevant
for QEMU. Use a simple index instead.

With this change, we can now increase the max socket number to 16 as
found on high end systems.

665cddbe15 hw/arm/virt: Delete EL3 error checksnow provided in CPU realize
Now that the CPU realize function will fail cleanly if we ask for EL3
when KVM is enabled, we don't need to check for errors explicitly in
the virt board code. The reported message is slightly different;
it is now:
  qemu-system-aarch64: Cannot enable KVM when guest CPU has EL3 enabled
instead of:
  qemu-system-aarch64: mach-virt: KVM does not support Security extensions

We don't delete the MTE check because there the logic is more
complex; deleting the check would work but makes the error message
less helpful, as it would read:
  qemu-system-aarch64: MTE requested, but not supported by the guest CPU
instead of:
  qemu-system-aarch64: mach-virt: KVM does not support providing MTE to the guest CPU

312c496a95 hw/core/loader: In gunzip(), check index is in range before use, not after
The gunzip() function reads various fields from a passed in source
buffer in order to skip a header before passing the actual compressed
data to the zlib inflate() function.  It does check whether the
passed in buffer is too small, but unfortunately it checks that only
after reading bytes from the src buffer, so it could read off the end
of the buffer.

You can see this with valgrind:

0659e4680e hw/arm/Kconfig: no need to enable ACPI_MEMORY_HOTPLUG/ACPI_NVDIMM explicitly
Since commit
36b79e3219 ("hw/acpi/Kconfig: Add missing Kconfig dependencies (build error)"),
ACPI_MEMORY_HOTPLUG and ACPI_NVDIMM is implicitly turned on when
ACPI_HW_REDUCED is selected. ACPI_HW_REDUCED is already enabled. No need to
turn on ACPI_MEMORY_HOTPLUG or ACPI_NVDIMM explicitly. This is a minor cleanup.

96ac971933 multi-process: Fix pci_proxy_dev_realize() error handling
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

pci_proxy_dev_realize() is wrong that way: it passes @errp to
qio_channel_new_fd() without checking for failure.  If it runs into
another failure, it trips error_setv()'s assertion.

Fix it to check for failure properly.

d7f5013e12 spapr: Explain purpose of ->fwnmi_migration_blocker more clearly
spapr_mce_req_event() makes an effort to prevent migration from
degrading the reporting of FWNMIs.  It adds a migration blocker when
it receives one, and deletes it when it's done handling it.  This is a
best effort.

Commit 2500fb423a "migration: Include migration support for machine
check handling" tried to explain this in a comment.  Rewrite the
comment for clarity, and reposition it to make it clear it applies to
all failure modes, not just "migration already in progress".

80d60a6d1e sbsa-ref: Rename SBSA_GWDT enum value
The SBSA_GWDT enum value conflicts with the SBSA_GWDT() QOM type
checking helper, preventing us from using a OBJECT_DEFINE* or
DEFINE_INSTANCE_CHECKER macro for the SBSA_GWDT() wrapper.

If I understand the SBSA 6.0 specification correctly, the signal
being connected to IRQ 16 is the WS0 output signal from the
Generic Watchdog.  Rename the enum value to SBSA_GWDT_WS0 to be
more explicit and avoid the name conflict.

ea0aa1752c hw/core: fix error checking in smp_parse
machine_set_smp() mistakenly checks 'errp' not '*errp',
and so thinks there is an error every single time it runs.
This causes it to jump to the end of the method, skipping
the max CPUs checks. The caller meanwhile sees no error
and so carries on execution. The result of all this is:

 $ qemu-system-x86_64 -smp -1
 qemu-system-x86_64: GLib: ../glib/gmem.c:142: failed to allocate 481036337048 bytes

instead of

 $ qemu-system-x86_64 -smp -1
 qemu-system-x86_64: Invalid SMP CPUs -1. The max CPUs supported by machine 'pc-i440fx-6.1' is 255

This is a regression from

bf7b1eab25 chardev: mark explicitly first argument as poisoned
Since commit 9894dc0cdc "char: convert
from GIOChannel to QIOChannel", the first argument to the watch callback
can actually be a QIOChannel, which is not a GIOChannel (but a QEMU
Object).

Even though we never used that pointer, change the callback type to warn
the users. Possibly a better fix later, we may want to store the
callback and call it from intermediary functions.

40c3472a29 Revert "acpi/gpex: Inform os to keep firmware resource map"
This reverts commit 0cf8882fd0.

Which this commit, with aarch64 when using efi PCI devices with IO ports
do not work.  The reason is that EFI creates I/O port mappings below
0x1000 (in fact, at 0). However Linux, for legacy reasons, does not
support I/O ports <= 0x1000 on PCI, so the I/O assignment created by EFI
is rejected.

EFI creates the mappings primarily for itself, and up until DSM #5
started to be enforced, all PCI resource allocations that existed at
boot were ignored by Linux and recreated from scratch.

Also, the commit in question looks dubious - it seems unlikely that
Linux would fail to create a resource tree. What does
happen is that BARs get moved around, which may cause trouble in some
cases: for instance, Linux had to add special code to the EFI framebuffer
driver to copy with framebuffer BARs being relocated.

DSM #5 has a long history of debate and misinterpretation.

d7346e614f acpi: x86: pcihp: add support hotplug on multifunction bridges
Commit [1] switched PCI hotplug from native to ACPI one by default.

That however breaks hotplug on following CLI that used to work:
   -nodefaults -machine q35 \
   -device pcie-root-port,id=pcie-root-port-0,multifunction=on,bus=pcie.0,addr=0x1,chassis=1 \
   -device pcie-root-port,id=pcie-root-port-1,port=0x1,addr=0x1.0x1,bus=pcie.0,chassis=2

where PCI device is hotplugged to pcie-root-port-1 with error on guest side:

  ACPI BIOS Error (bug): Could not resolve symbol [^S0B.PCNT], AE_NOT_FOUND (20201113/psargs-330)
  ACPI Error: Aborting method \_SB.PCI0.PCNT due to previous error (AE_NOT_FOUND) (20201113/psparse-531)
  ACPI Error: Aborting method \_GPE._E01 due to previous error (AE_NOT_FOUND) (20201113/psparse-531)
  ACPI Error: AE_NOT_FOUND, while evaluating GPE method [_E01] (20201113/evgpe-515)

cause is that QEMU's ACPI hotplug never supported functions other then 0
and due to bug it was generating notification entries for not described
functions.

Technically there is no reason not to describe cold-plugged bridges
(root ports) on functions other then 0, as they similarly to bridge
on function 0 are unpluggable.

So since we need to describe multifunction devices iterate over
fuctions as well. But describe only cold-plugged bridges[root ports]
on functions other than 0 as well.

e2a6290aab hw/pcie-root-port: Fix hotplug for PCI devices requiring IO
Q35 has now ACPI hotplug enabled by default for PCI(e) devices.
As opposed to native PCIe hotplug, guests like Fedora 34
will not assign IO range to pcie-root-ports not supporting
native hotplug, resulting into a regression.

Reproduce by:
    qemu-bin -M q35 -device pcie-root-port,id=p1 -monitor stdio
    device_add e1000,bus=p1
In the Guest OS the respective pcie-root-port will have the IO range
disabled.

Fix it by setting the "reserve-io" hint capability of the
pcie-root-ports so the firmware will allocate the IO range instead.
