94a9471ceb docs: Explain how to use passt
Add a chapter to explain how to use passt(1) instead of '-net user'.
passt(1) can be connected to QEMU using UNIX socket or vhost-user.
With vhost-user, migration of the VM is allowed and internal state of
passt(1) is transfered from one side to the other

ce5a32d180 ppc/pnv: Move the PNOR LPC address into struct PnvPnor
Rather than use the hardcoded define throughout the tree for the
PNOR LPC address, keep it within the PnvPnor object.

This should solve a dead code issue in the BMC HIOMAP checks where
Coverity (correctly) reported that the sanity checks are dead code.
We would like to keep the sanity checks without turning them into a
compile time assert in case we would like to make them configurable
in future.

d1368344bc rust: Kconfig: Factor out whether HPET is Rust or C
Currently we require everywhere that wants to know if there
is an HPET device to check for "CONFIG_HPET || CONFIG_X_HPET_RUST".
Factor out whether the HPET device is Rust or C into a separate
Kconfig stanza, so that CONFIG_HPET means "there is an HPET",
and whether this has pulled in CONFIG_X_HPET_RUST or CONFIG_HPET_C
is something the rest of QEMU can ignore.

f88c9cd804 rust: Kconfig: Factor out whether PL011 is Rust or C
Currently every board that uses the PL011 duplicates the logic that
selects the Rust implementation if Rust was enabled and the C
implementation if it does not.  Factor this out into a separate
Kconfig stanza, so that boards can go back to simply doing "select
PL011" and get whichever implementation is correct for the build.

This fixes a compilation failure if CONFIG_VMAPPLE is enabled
in a Rust build, because hw/vmapple/Kconfig didn't have the
"pick the Rust PL011 if Rust is enabled" logic in it.

a725bc970e target/loongarch: Clean up virt_cpu_irq_init() 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.

virt_cpu_irq_init() is wrong that way: it passes &err to
hotplug_handler_plug() twice.  If both calls failed, this could trip
error_setv()'s assertion.  Moreover, if just one fails, the Error
object leaks. Fortunately, these calls can't actually fail.

Messed up in commit 50ebc3fc47 (hw/intc/loongarch_ipi: Notify ipi
object when cpu is plugged) and commit 087a23a87c
(hw/intc/loongarch_extioi: Use cpu plug notification).

fb802acdc8 ppc/spapr: Fix RTAS stopped state
This change takes the CPUPPCState 'quiesced' field added for powernv
hardware CPU core controls (used to stop and start cores), and extends
it to spapr to model the "RTAS stopped" state. This prevents the
schedulers attempting to run stopped CPUs unexpectedly, which can cause
hangs and possibly other unexpected behaviour.

The detail of the problematic situation is this:

A KVM spapr guest boots with all secondary CPUs defined to be in the
"RTAS stopped" state. In this state, the CPU is only responsive to the
start-cpu RTAS call. This behaviour is modeled in QEMU with the
start_powered_off feature, which sets ->halted on secondary CPUs at
boot. ->halted=true looks like an idle / sleep / power-save state which
typically is responsive to asynchronous interrupts, but spapr clears
wake-on-interrupt bits in the LPCR SPR. This more-or-less works.

Commit e8291ec16d ("target/ppc: fix timebase register reset state")
recently caused the decrementer to expire sooner at boot, causing a
decrementer exception on secondary CPUs in RTAS stopped state. This
was not a problem on TCG, but KVM limits how a guest can modify LPCR, in
particular it prevents the clearing of wake-on-interrupt bits, and so in
the course of CPU register synchronisation, the LPCR as set by spapr to
model the RTAS stopped state is overwritten with KVM's LPCR value, and
that then causes QEMU's interrupt code to notice the expired decrementer
exception, turn that into an interrupt, and set CPU_INTERRUPT_HARD.

That causes the CPU to be kicked, and the KVM vCPU thread to loop
calling kvm_cpu_exec(). kvm_cpu_exec() calls
kvm_arch_process_async_events(), which on ppc just returns ->halted.
This is still true, so it returns immediately with EXCP_HLT, and the
vCPU never goes to sleep because qemu_wait_io_event() sees
CPU_INTERRUPT_HARD is set. All this while the vCPU holds the bql.  This
causes the boot CPU to eventually lock up when it needs the bql.

So make 'quiesced' represent the "RTAS stopped" state, and have it
explicitly not respond to exceptions (interrupt conditions) rather than
rely on machine register state to model that state. This matches the
powernv quiesced state very well because it essentially turns off the
CPU core via a side-band control unit.

There are still issues with QEMU and KVM idea of LPCR diverging and that
is quite ugly and fragile that should be fixed. spapr should synchronize
its LPCR properly with KVM, and not try to use values that KVM does not
support.

f700abbbeb tests/functional/test_migration: Use "ncat" instead of "nc" in the exec test
"nc" can either be GNU netcat, OpenBSD netcat or NMap ncat. At
least GNU netcat currently does not work with this test anymore,
though the comment in the test says otherwise. GNU netcat seems
to be quite unmaintained nowadays, according to its website
(https://netcat.sourceforge.net/), the last public release is from
2004, so we should rather avoid that binary.
In our CI, we are only using "ncat" in the containers (it's the only
flavor that lcitool supports), thus to avoid silent regressions with
the other netcats, let's limit this test to "ncat" only now.

4e9e2478df target/riscv: fix handling of nop for vstart >= vl in some vector instruction
Recently, when I was writing a RISCV test, I found that when VL is set to 0, the
instruction should be nop, but when I tested it, I found that QEMU will treat
all elements as tail elements, and in the case of VTA=1, write all elements
to 1.

After troubleshooting, it was found that the vext_vx_rm_1 function was called in
the vext_vx_rm_2, and then the vext_set_elems_1s function was called to process
the tail element, but only VSTART >= vl was checked in the vext_vx_rm_1
function, which caused the tail element to still be processed even if it was
returned in advance.

So I've made the following change:

Put VSTART_CHECK_EARLY_EXIT(env) at the beginning of the vext_vx_rm_2 function,
so that the VSTART register is checked correctly.
