deef3d2568 intc/ibex_plic: Ensure we don't loose interrupts
If an interrupt occurs between when we claim and complete an interrupt
we currently drop the interrupt in ibex_plic_irqs_set_pending(). This
somewhat matches hardware that also ignore the interrupt between the
claim and complete process.

In the case of hardware though the physical interrupt line will still
be asserted after we have completed the interrupt. This means we will
still act on the interrupt after the complete process. In QEMU we don't
and instead we drop the interrupt as it is never recorded.

This patch changed the behaviour of the Ibex PLIC so that we save all
interrupts that occur while we are between claiming and completing an
interrupt so that we can act on them after the completition process.

This fixes interrupts being dropped when running Tock on OpenTitain in
QEMU.

96338fefc1 hw/intc/ibex_plic: Clear the claim register when read
After claiming the interrupt by reading the claim register we want to
clear the register to make sure the interrupt doesn't appear at the next
read.

This matches the documentation for the claim register as when an interrupt
is claimed by a target the relevant bit of IP is cleared (which we already
do): https://docs.opentitan.org/hw/ip/rv_plic/doc/index.html

This also matches the current hardware.

c20a135a7a hw/intc/arm_gicv3_cpuif: Make GIC maintenance interrupts work
In gicv3_init_cpuif() we copy the ARMCPU gicv3_maintenance_interrupt
into the GICv3CPUState struct's maintenance_irq field.  This will
only work if the board happens to have already wired up the CPU
maintenance IRQ before the GIC was realized.  Unfortunately this is
not the case for the 'virt' board, and so the value that gets copied
is NULL (since a qemu_irq is really a pointer to an IRQState struct
under the hood).  The effect is that the CPU interface code never
actually raises the maintenance interrupt line.

Instead, since the GICv3CPUState has a pointer to the CPUState, make
the dereference at the point where we want to raise the interrupt, to
avoid an implicit requirement on board code to wire things up in a
particular order.

d20c3ebda2 hw/intc/armv7m_nvic: Only show ID register values for Main Extension CPUs
M-profile CPUs only implement the ID registers as guest-visible if
the CPU implements the Main Extension (all our current CPUs except
the Cortex-M0 do).

Currently we handle this by having the Cortex-M0 leave the ID
register values in the ARMCPU struct as zero, but this conflicts with
our design decision to make QEMU behaviour be keyed off ID register
fields wherever possible.

Explicitly code the ID registers in the NVIC to return 0 if the Main
Extension is not implemented, so we can make the M0 model set the
ARMCPU struct fields to obtain the correct behaviour without those
values becoming guest-visible.

d73415a315 qemu/atomic.h: rename atomic_ to qatomic_
clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:

  $ CC=clang CXX=clang++ ./configure ... && make
  ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)

Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.

This patch was generated using:

  $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \
    sort -u >/tmp/changed_identifiers
  $ for identifier in $(</tmp/changed_identifiers); do
        sed -i "s%\<$identifier\>%q$identifier%g" \
            $(git grep -I -l "\<$identifier\>")
    done

I manually fixed line-wrap issues and misaligned rST tables.

fa34a3c58a Use DECLARE_*CHECKER* when possible (--force mode)
Separate run of the TypeCheckMacro converter using the --force

header nor in typedefs.h.

Generated initially using:

 $ ./scripts/codeconverter/converter.py --force -i \
   --pattern=TypeCheckMacro $(git grep -l '' -- '*.[ch]')

Then each case was manually reviewed, and a comment was added
indicating what's unusual about those type checking
macros/functions.  Despite not following the usual pattern, the
changes in this patch were found to be safe.

db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

eab0a2d06e spapr/xive: Allocate vCPU IPIs from the vCPU contexts
When QEMU switches to the XIVE interrupt mode, it creates all the
guest interrupts at the level of the KVM device. These interrupts are
backed by real HW interrupts from the IPI interrupt pool of the XIVE
controller.

Currently, this is done from the QEMU main thread, which results in
allocating all interrupts from the chip on which QEMU is running. IPIs
are not distributed across the system and the load is not well
balanced across the interrupt controllers.

Change the vCPU IPI allocation to run from the vCPU context. The
associated XIVE IPI interrupt will be allocated on the chip on which
the vCPU is running and improve distribution of the IPIs in the system.
When the vCPUs are pinned, this will make the IPI local to the chip of
the vCPU. It will reduce rerouting between interrupt controllers and
gives better performance.

Device interrupts are still treated the same. To improve placement, we
would need some information on the chip owning the virtual source or
the HW source in case of a passthrough device but this reuires
changes in PAPR.

acbdb9956f spapr/xive: Allocate IPIs independently from the other sources
The vCPU IPIs are now allocated in kvmppc_xive_cpu_connect() when the
vCPU connects to the KVM device and not when all the sources are reset
in kvmppc_xive_source_reset()

This requires extra care for hotplug vCPUs and VM restore.

4f311a7089 spapr/xive: Add a 'hv-prio' property to represent the KVM escalation priority
On POWER9, the KVM XIVE device uses priority 7 for the escalation
interrupts. On POWER10, the host can use a reduced set of priorities
and KVM will configure the escalation priority to a lower number. In
any case, the guest is allowed to use priorities in a single range :

    [ 0 .. (maxprio - 1) ].

Introduce a 'hv-prio' property to represent the escalation priority
number and use it to compute the "ibm,plat-res-int-priorities"
property defining the priority ranges reserved by the hypervisor.

243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.
