In commit 2c5fa0778c we fixed an endianness bug in the Allwinner
A10 PIC model; however in the process we introduced a regression.
This is because the old code was robust against the incoming 'level'
argument being something other than 0 or 1, whereas the new code was
not.
In particular, the allwinner-sdhost code treats its IRQ line
as 0-vs-non-0 rather than 0-vs-1, so when the SD controller
set its IRQ line for any reason other than transmit the
interrupt controller would ignore it. The observed effect
was a guest timeout when rebooting the guest kernel.
Handle level values other than 0 or 1, to restore the old
behaviour.

When dumping the END and NVP tables ("info pic" from the HMP) on the
P10 model, we're likely to be flooded with error messages such as:
XIVE[0] - VST: invalid NVPT entry f33800 !?
The error is printed when finding an empty VSD in an indirect
table (thus END and NVP tables with skiboot), which is going to happen
when dumping the xive state. So let's tune down those messages. They
can be re-enabled easily with a macro if needed.
Those errors were already hidden on xive/P9, for the same reason.

The Thread Interrupt Management Area (TIMA) can be accessed through 4
ports, targeted by the address. The base address of a TIMA
is using port 0 and the other ports are 0x80 apart. Using one port or
another can be useful to balance the load on the snoop buses. With
skiboot and linux, we currently use port 0, but as it tends to be
busy, another hypervisor is using port 1 for TIMA access.
The port address bits fall in between the special op indication
bits (the 2 MSBs) and the register offset bits (the 6 LSBs). They are
"don't care" for the hardware when processing a TIMA operation. This
patch filters out those port address bits so that a TIMA operation can
be triggered using any port.
It is also true for indirect access (through the IC BAR) and it's
actually nothing new, it was already the case on P9. Which helps here,
as the TIMA handling code is common between P9 (xive) and P10 (xive2).

The Allwinner PIC model uses set_bit() and clear_bit() to update the
values in its irq_pending[] array when an interrupt arrives. However
it is using these functions wrongly: they work on an array of type
'long', and it is passing an array of type 'uint32_t'. Because the
code manually figures out the right array element, this works on
little-endian hosts and on 32-bit big-endian hosts, where bits 0..31
in a 'long' are in the same place as they are in a 'uint32_t'.
However it breaks on 64-bit big-endian hosts.
Remove the use of set_bit() and clear_bit() in favour of using
deposit32() on the array element. This fixes a bug where on
big-endian 64-bit hosts the guest kernel would hang early on in
bootup.

A Linux guest will perform IRQ migration after the IRQ has happened,
updating the RTE to point to the new destination CPU and then unmasking
the interrupt.
However, when the guest updates the RTE, ioapic_mem_write() calls
ioapic_service(), which redelivers the pending level interrupt via
kvm_set_irq(), *before* calling ioapic_update_kvm_routes() which sets
the new target CPU.
Thus, the IRQ which is supposed to go to the new target CPU is instead
misdelivered to the previous target. An example where the guest kernel
is attempting to migrate from CPU#2 to CPU#0 shows:

There are no other code paths in ioapic_mem_write() which need the KVM
IRQ routing table to be updated, so just shift the call from the end
of the function to happen right before the call to ioapic_service()
and thus deliver the re-enabled IRQ to the right place.
Alternative fixes might have been just to remove the part in
ioapic_service() which delivers the IRQ via kvm_set_irq() because
surely delivering as MSI ought to work just fine anyway in all cases?
That code lacks a comment justifying its existence.
Or maybe in the specific case shown in the above log, it would have
sufficed for ioapic_update_kvm_routes() to update the route *even*
when the IRQ is masked. It's not like it's actually going to get
triggered unless QEMU deliberately does so, anyway? But that only
works because the target CPU happens to be in the high word of the
RTE; if something in the *low* word (vector, perhaps) was changed
at the same time as the unmask, we'd still trigger with stale data.

Even in the PIIX3 datasheet from 1996 this is documented as 'This bit is

We currently only support GICv2 emulation. To also support GICv3, we will
need to pass a few system registers into their respective handler functions.
This patch adds support for HVF to call into the TCG callbacks for GICv3
system register handlers. This is safe because the GICv3 TCG code is generic
as long as we limit ourselves to EL0 and EL1 - which are the only modes
supported by HVF.
To make sure nobody trips over that, we also annotate callbacks that don't
work in HVF mode, such as EL state change hooks.
With GICv3 support in place, we can run with more than 8 vCPUs.

The 'hwaddr' type is defined in "exec/hwaddr.h" as:
hwaddr is the type of a physical address
(its size can be different from 'target_ulong').
All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx:
$ fgrep define include/exec/hwaddr.h
#define HWADDR_H
#define HWADDR_BITS 64
#define HWADDR_MAX UINT64_MAX
#define TARGET_FMT_plx "%016" PRIx64
^^^^^^
#define HWADDR_PRId PRId64
#define HWADDR_PRIi PRIi64
#define HWADDR_PRIo PRIo64
#define HWADDR_PRIu PRIu64
#define HWADDR_PRIx PRIx64
#define HWADDR_PRIX PRIX64
Since hwaddr's size can be *different* from target_ulong, it is
very confusing to read one of its format using the 'TARGET_FMT_'
prefix, normally used for the target_long / target_ulong types:
$ fgrep TARGET_FMT_ include/exec/cpu-defs.h
#define TARGET_FMT_lx "%08x"
#define TARGET_FMT_ld "%d"
#define TARGET_FMT_lu "%u"
#define TARGET_FMT_lx "%016" PRIx64
#define TARGET_FMT_ld "%" PRId64
#define TARGET_FMT_lu "%" PRIu64
Apparently this format was missed during commit a8170e5e97
("Rename target_phys_addr_t to hwaddr"), so complete it by
doing a bulk-rename with:
$ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx)

These IRQ counting functions will soon be required in binaries that
do not include the APIC code, too, so let's extract them into a
separate file that can be linked independently of the APIC code.
While we're at it, change the apic_* prefix into kvm_* since the
functions are used from the i8259 PIC (i.e. not the APIC), too.

The pending register upper limit is currently set to
plic->num_sources >> 3, which is wrong, e.g.: considering
plic->num_sources is 7, the upper limit becomes 0 which fails
the range check if reading the pending register at pending_base.
