42c93917f7 hw/usb: pacify xhciwmi.exe warning
xhciwmi.exe is used inside Windows 2022 SVVP tests. This tool called as
'xhciwmi.exe --verify' reports that 'The firmware loaded on this
controller has known bugs and/or compatibility issues'. This is just
a warning but there is no particular sense to ignore it.

This patch just pacifies the tool.

There is a big question whether this change should be put using
machine type mechanics, but at my opinion this would be an overkill.

b72c9d5951 target/nios2: Rewrite interrupt handling
Previously, we would avoid setting CPU_INTERRUPT_HARD when interrupts
are disabled at a particular point in time, instead queuing the value
into cpu->irq_pending.  This is more complicated than required.

Instead, set CPU_INTERRUPT_HARD any time there is a pending interrupt,
and exclusively check for interrupts disabled in nios2_cpu_exec_interrupt.

44219b6029 hw/nvme: 64-bit pi support
This adds support for one possible new protection information format
introduced in TP4068 (and integrated in NVMe 2.0): the 64-bit CRC guard
and 48-bit reference tag. This version does not support storage tags.

Like the CRC16 support already present, this uses a software
implementation of CRC64 (so it is naturally pretty slow). But its good
enough for verification purposes.

This may go nicely hand-in-hand with the support that Keith submitted
for the Linux kernel[1].

with machine name in the QEMU command-line. The AIA IMSIC is
only a per-HART MSI controller so we use AIA APLIC in MSI-mode
to forward all wired interrupts as MSIs to the AIA IMSIC.

We also provide "aia-guests=<xyz>" parameter which can be used
to specify number of VS-level AIA IMSIC Guests MMIO pages for
each HART.

9746e583fe hw/intc: Add RISC-V AIA IMSIC device emulation
The RISC-V AIA (Advanced Interrupt Architecture) defines a new
interrupt controller for MSIs (message signal interrupts) called
IMSIC (Incoming Message Signal Interrupt Controller). The IMSIC
is per-HART device and also suppport virtualizaiton of MSIs using
dedicated VS-level guest interrupt files.

This patch adds device emulation for RISC-V AIA IMSIC which
supports M-level, S-level, and VS-level MSIs.

268c11984e ui/cocoa.m: Remove unnecessary NSAutoreleasePools
In commit 6e657e64cd in 2013 we added some autorelease pools to
deal with complaints from macOS when we made calls into Cocoa from
threads that didn't have automatically created autorelease pools.
Later on, macOS got stricter about forbidding cross-thread Cocoa
calls, and in commit 5588840ff7 we restructured the code to
avoid them.  This left the autorelease pool creation in several
functions without any purpose; delete it.

We still need the pool in cocoa_refresh() for the clipboard related
code which is called directly there.

8d65dee2c4 ui/cocoa.m: Fix updateUIInfo threading issues
The updateUIInfo method makes Cocoa API calls.  It also calls back
into QEMU functions like dpy_set_ui_info().  To do this safely, we
need to follow two rules:
 * Cocoa API calls are made on the Cocoa UI thread
 * When calling back into QEMU we must hold the iothread lock

Fix the places where we got this wrong, by taking the iothread lock
while executing updateUIInfo, and moving the call in cocoa_switch()
inside the dispatch_async block.

Some of the Cocoa UI methods which call updateUIInfo are invoked as
part of the initial application startup, while we're still doing the
little cross-thread dance described in the comment just above
call_qemu_main().  This meant they were calling back into the QEMU UI
layer before we'd actually finished initializing our display and
registered the DisplayChangeListener, which isn't really valid.  Once
updateUIInfo takes the iothread lock, we no longer get away with
this, because during this startup phase the iothread lock is held by
the QEMU main-loop thread which is waiting for us to finish our
display initialization.  So we must suppress updateUIInfo until
applicationDidFinishLaunching allows the QEMU main-loop thread to
continue.

dc8bc9d657 target/arm: Report KVM's actual PSCI version to guest in dtb
When we're using KVM, the PSCI implementation is provided by the
kernel, but QEMU has to tell the guest about it via the device tree.
Currently we look at the KVM_CAP_ARM_PSCI_0_2 capability to determine
if the kernel is providing at least PSCI 0.2, but if the kernel
provides a newer version than that we will still only tell the guest
it has PSCI 0.2.  (This is fairly harmless; it just means the guest
won't use newer parts of the PSCI API.)

The kernel exposes the specific PSCI version it is implementing via
the ONE_REG API; use this to report in the dtb that the PSCI
implementation is 1.0-compatible if appropriate.  (The device tree
binding currently only distinguishes "pre-0.2", "0.2-compatible" and
"1.0-compatible".)

ef56c2425e target/arm: Implement FEAT_LPA2
This feature widens physical addresses (and intermediate physical
addresses for 2-stage translation) from 48 to 52 bits, when using
4k or 16k pages.

This introduces the DS bit to TCR_ELx, which is RES0 unless the
page size is enabled and supports LPA2, resulting in the effective
value of DS for a given table walk.  The DS bit changes the format
of the page table descriptor slightly, moving the PS field out to
TCR so that all pages have the same sharability and repurposing
those bits of the page table descriptor for the highest bits of
the output address.

Do not yet enable FEAT_LPA2; we need extra plumbing to avoid
tickling an old kernel bug.
