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].

hw/riscv: virt: Add optional AIA IMSIC support to virt machine
We extend virt machine to emulate both AIA IMSIC and AIA APLIC
devices only when "aia=aplic-imsic" parameter is passed along
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.

ui/cocoa.m: Remove unnecessary NSAutoreleasePools
In commit
6e657e64cdc478 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
5588840ff77800e839d8 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

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.

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

*does* have a TSC2005 at this address.) The TSC2005 supports the
24-bit accesses which the guest driver makes, and the TSC210x does
not (that is, our TSC210x emulation is not missing support for a word
width the hardware can handle). It's not clear whether the problem
here is that the guest kernel incorrectly thinks the n800 has the
same device at this SPI bus address as the n810, or that QEMU's n810
board model doesn't get the SPI devices right. At this late date
there no longer appears to be any reliable information on the web
about the hardware behaviour, but I am inclined to think this is a
guest kernel bug. In any case, we prefer not to abort QEMU for
guest-triggerable conditions, so logging the error is the right thing
to do.

mps3-an547: Add missing user ahb interfaces
With these interfaces missing, TFM would delegate peripherals 0, 1,

it thought interface 4 was eth & USB.
This patch corrects this behavior and allows TFM to delegate the
eth & USB peripheral to NS mode.

migration: Enlarge postcopy recovery to capture !-EIO too
We used to have quite a few places making sure -EIO happened and that's the
only way to trigger postcopy recovery. That's based on the assumption that
we'll only return -EIO for channel issues.
It'll work in 99.99% cases but logically that won't cover some corner cases.
One example is e.g. ram_block_from_stream() could fail with an interrupted
network, then -EINVAL will be returned instead of -EIO.
I remembered Dave Gilbert pointed that out before, but somehow this is
overlooked. Neither did I encounter anything outside the -EIO error.
However we'd better touch that up before it triggers a rare VM data loss during
live migrating.
To cover as much those cases as possible, remove the -EIO restriction on
triggering the postcopy recovery, because even if it's not a channel failure,
we can't do anything better than halting QEMU anyway - the corpse of the
process may even be used by a good hand to dig out useful memory regions, or
the admin could simply kill the process later on.

Peter Xu [Tue, 1 Mar 2022 08:39:04 +0000 (16:39 +0800)]
migration: Introduce postcopy channels on dest node
Postcopy handles huge pages in a special way that currently we can only have
one "channel" to transfer the page.
It's because when we install pages using UFFDIO_COPY, we need to have the whole
huge page ready, it also means we need to have a temp huge page when trying to
receive the whole content of the page.
Currently all maintainance around this tmp page is global: firstly we'll
allocate a temp huge page, then we maintain its status mostly within
ram_load_postcopy().
To enable multiple channels for postcopy, the first thing we need to do is to
prepare N temp huge pages as caching, one for each channel.
Meanwhile we need to maintain the tmp huge page status per-channel too.
To give some example, some local variables maintained in ram_load_postcopy()
are listed; they are responsible for maintaining temp huge page status:
- all_zero: this keeps whether this huge page contains all zeros
- target_pages: this counts how many target pages have been copied
- host_page: this keeps the host ptr for the page to install
Move all these fields to be together with the temp huge pages to form a new
structure called PostcopyTmpPage. Then for each (future) postcopy channel, we
need one structure to keep the state around.
For vanilla postcopy, obviously there's only one channel. It contains both
precopy and postcopy pages.
This patch teaches the dest migration node to start realize the possible number
of postcopy channels by introducing the "postcopy_channels" variable. Its
value is calculated when setup postcopy on dest node (during POSTCOPY_LISTEN
phase).
Vanilla postcopy will have channels=1, but when postcopy-preempt capability is
enabled (in the future), we will boost it to 2 because even during partial
sending of a precopy huge page we still want to preempt it and start sending
the postcopy requested page right away (so we start to keep two temp huge
pages; more if we want to enable multifd). In this patch there's a TODO marked
for that; so far the channels is always set to 1.
We need to send one "host huge page" on one channel only and we cannot split
them, because otherwise the data upon the same huge page can locate on more
than one channel so we need more complicated logic to manage. One temp host
huge page for each channel will be enough for us for now.
Postcopy will still always use the index=0 huge page even after this patch.
However it prepares for the latter patches where it can start to use multiple
channels (which needs src intervention, because only src knows which channel we
should use).

hw/ppc/spapr_numa.c: simplify spapr_numa_write_assoc_lookup_arrays()
We can get the job done in spapr_numa_write_assoc_lookup_arrays() a bit
cleaner:
- 'cur_index = int_buf = g_malloc0(..)' is doing a g_malloc0() in the
'int_buf' pointer and making 'cur_index' point to 'int_buf' all in a
single line. No problem with that, but splitting into 2 lines is clearer
to follow
- use g_autofree in 'int_buf' to avoid a g_free() call later on
- 'buf_len' is only being used to store the size of 'int_buf' malloc.
Remove the var and just use the value in g_malloc0() directly
- remove the 'ret' var and just return the result of fdt_setprop()

hw/ppc/spapr_drc.c: use g_auto in spapr_dt_drc()
Use g_autoptr() with GArray* and GString* pointers to avoid calling
g_free() and the need for the 'out' label.
'drc_name' can also be g_autofreed to avoid a g_free() call at the end
of the while() loop.

hw/ppc/spapr.c: fail early if no firmware found in machine_init()
The firmware check consists on a file search (qemu_find_file) and load
it via load_imag_targphys(). This validation is not dependent on any
other machine state but it currently being done at the end of
spapr_machine_init(). This means that we can do a lot of stuff and end
up failing at the end for something that we can verify right out of the
gate.
Move this validation to the start of spapr_machine_init() to fail
earlier. While we're at it, use g_autofree in the 'filename' pointer.
