c4b3f46c15 include/exec: Move vaddr defines to separate file
Needed to work around circular includes. vaddr is currently defined in
cpu-common.h and needed by hw/core/cpu.h, but cpu-common.h also need
cpu.h to know the size of the CPUState.

[Maybe we can instead move parts of cpu-common.h w. hw/core/cpu.h to
sort out the circular inclusion.]

d157e540ed cpu-exec: simplify jump cache management
Unless I'm missing something egregious, the jmp cache is only every
populated with a valid entry by the same thread that reads the cache.
Therefore, the contents of any valid entry are always consistent and
there is no need for any acquire/release magic.

Indeed ->tb has to be accessed with atomics, because concurrent
invalidations would otherwise cause data races.  But ->pc is only ever
accessed by one thread, and accesses to ->tb and ->pc within tb_lookup
can never race with another tb_lookup.  While the TranslationBlock
(especially the flags) could be modified by a concurrent invalidation,
store-release and load-acquire operations on the cache entry would
not add any additional ordering beyond what you get from performing
the accesses within a single thread.

Because of this, there is really nothing to win in splitting the CF_PCREL
and !CF_PCREL paths.  It is easier to just always use the ->pc field in
the jump cache.

I noticed this while working on splitting commit 8ed558ec0c
("accel/tcg: Introduce TARGET_TB_PCREL", 2022-10-04) into multiple
pieces, for the sake of finding a more fine-grained bisection
result for https://gitlab.com/qemu-project/qemu/-/issues/2092.
It does not (and does not intend to) fix that issue; therefore
it may make sense to not commit it until the root cause
of issue #2092 is found.

18281b2578 bswap.h: Fix const_le64() macro
The const_le64() macro introduced in commit 845d80a8c7 turns out
to have a bug which means that on big-endian systems the compiler
complains if the argument isn't already a 64-bit type. This hasn't
caused a problem yet, because there are no in-tree uses, but it
means it's not possible for anybody to add one without it failing CI.

This example is from an attempted use of it with the argument '0',
from the s390 CI runner's gcc:

../block/blklogwrites.c: In function ‘blk_log_writes_co_do_log’:
../include/qemu/bswap.h:148:36: error: left shift count >= width of

409 | .nr_entries = const_le64(0),
| ^~~~~~~~~~
cc1: all warnings being treated as errors

Fix this by making all the constants in the macro have the ULL
suffix.  This will cause them all to be 64-bit integers, which means
the result of the logical & will also be an unsigned 64-bit type,
even if the input to the macro is a smaller type, and so the shifts
will be in range.

6fffc83785 target/arm: Fix A64 scalar SQSHRN and SQRSHRN
In commit 1b7bc9b5c8 we changed handle_vec_simd_sqshrn() so
that instead of starting with a 0 value and depositing in each new
element from the narrowing operation, it instead started with the raw
result of the narrowing operation of the first element.

This is fine in the vector case, because the deposit operations for
the second and subsequent elements will always overwrite any higher
bits that might have been in the first element's result value in
tcg_rd.  However in the scalar case we only go through this loop
once.  The effect is that for a signed narrowing operation, if the
result is negative then we will now return a value where the bits
above the first element are incorrectly 1 (because the narrowfn
returns a sign-extended result, not one that is truncated to the
element size).

Fix this by using an extract operation to get exactly the correct
bits of the output of the narrowfn for element 1, instead of a
plain move.

988f244297 hw/char/imx_serial: Implement receive FIFO and ageing timer
This patch implements a 32 half word FIFO as per imx serial device
specifications.  If a non empty FIFO is below the trigger level, an
ageing timer will tick for a duration of 8 characters.  On expiry,
AGTIM will be set triggering an interrupt.  AGTIM timer resets when
there is activity in the receive FIFO.

Otherwise, RRDY is set when trigger level is exceeded.  The receive
trigger level is 8 in newer kernel versions and 1 in older ones.

This change will break migration compatibility for the imx boards.

1acf215998 docs/system/arm/virt.rst: Add note on CPU features off by default
Add a note on CPU features that are off by default in `virt` machines.
Some CPU features will remain off even if a CPU-capable CPU (e.g.,
`-cpu max`) is selected because they require support in both the CPU
itself and in the wider system. Therefore, the user, besides selecting a
CPU that supports such features, must also turn on the feature using a
machine option.

b0d1021ed9 fsl-imx6ul: Add various missing unimplemented devices
Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices.

This allows operating systems such as Linux to run emulations such as
mcimx6ul-evk.

Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected
memory ranges were covered by the unimplemented DAP device. The commit
reduced the DAP address range from 0x100000 to 4kB, and the emulation
thus no longer covered the various unimplemented devices in the affected
address range.

Except virt-acpi-build.c, all of them don't require any
ARM specific knowledge anymore and can be build once as
target agnostic units. Update meson accordingly.

Move Arm A-class Generic Timer definitions to the new
"target/arm/gtimer.h" header so units in hw/ which don't

d780d056f8 target/arm: Move ARM_CPU_IRQ/FIQ definitions to 'cpu-qom.h' header
The ARM_CPU_IRQ/FIQ definitions are used to index the GPIO
IRQ created calling qdev_init_gpio_in() in ARMCPU instance_init()
handler. To allow non-ARM code to raise interrupt on ARM cores,
move they to 'target/arm/cpu-qom.h' which is non-ARM specific and
can be included by any hw/ file.

File list to include the new header generated using:

ff7888dcc6 hw/arm/musicpal: Convert to qemu_add_kbd_event_handler()
Convert the musicpal key input device to use
qemu_add_kbd_event_handler().  This lets us simplify it because we no
longer need to track whether we're in the middle of a PS/2 multibyte
key sequence.

In the conversion we move the keyboard handler registration from init
to realize, because devices shouldn't disturb the state of the
simulation by doing things like registering input handlers until
they're realized, so that device objects can be introspected
safely.

The behaviour where key-repeat is permitted for the arrow-keys only
is intentional (added in commit 7c6ce4baed), so we retain it,
and add a comment to that effect.

This is a migration compatibility break for musicpal.

In arm_deliver_fault() we check for whether the fault is caused
by a data abort due to an access to a FEAT_NV2 sysreg in the
memory pointed to by the VNCR. Unfortunately part of the
condition checks the wrong argument to the function, meaning
that it would spuriously trigger, resulting in some instruction
aborts being taken to the wrong EL and reported incorrectly.

Use the right variable in the condition.

604927e357 target/xtensa: fix OOB TLB entry access
r[id]tlb[01], [iw][id]tlb opcodes use TLB way index passed in a register
by the guest. The host uses 3 bits of the index for ITLB indexing and 4
bits for DTLB, but there's only 7 entries in the ITLB array and 10 in
the DTLB array, so a malicious guest may trigger out-of-bound access to
these arrays.

Change split_tlb_entry_spec return type to bool to indicate whether TLB
way passed to it is valid. Change get_tlb_entry to return NULL in case
invalid TLB way is requested. Add assertion to xtensa_tlb_get_entry that
requested TLB way and entry indices are valid. Add checks to the
[rwi]tlb helpers that requested TLB way is valid and return 0 or do
nothing when it's not.

63b18312d1 tests/unit: Bump test-replication timeout to 60 seconds
We're seeing timeouts for this test on CI runs (specifically for
ubuntu-20.04-s390x-all). It doesn't fail consistently, but even the
successful runs take about 27 or 28 seconds, which is not very far from
the 30 seconds timeout.

Bump the timeout a bit to make failure less likely even on this CI host.

85d5d2b255 iotests/264: Use iotests.sock_dir for socket creation
If socket path is too long (longer than 108 bytes), socket can't be
opened.  This might lead to failure when test dir path is long enough.
Make sure socket is created in iotests.sock_dir to avoid such a case.

This commit basically aligns iotests/264 with the rest of iotests.

a26d018c94 block/blklogwrites: Protect mutable driver state with a mutex.
During the review of a fix for a concurrency issue in blklogwrites,
it was found that the driver needs an additional fix when enabling
multiqueue, which is a new feature introduced in QEMU 9.0, as the
driver state may be read and written by multiple threads at the same
time, which was not the case when the driver was originally written.

Fix the multi-threaded scenario by introducing a mutex to protect the
mutable fields in the driver state, and always having the mutex locked
by the current thread when accessing them. Also use the mutex and a
CoQueue to ensure that the super block is not being written to by
multiple threads concurrently and updates are properly serialized.

Additionally, add the const qualifier to a few BDRVBlkLogWritesState
pointer targets in contexts where the driver state is not written to.

d3f6f294ae virtio-blk: always set ioeventfd during startup
When starting ioeventfd it is common practice to set the event notifier
so that the ioeventfd handler is triggered to run immediately. There may
be no requests waiting to be processed, but the idea is that if a
request snuck in then we guarantee that it will be detected.

One scenario where self-triggering the ioeventfd is necessary is when
virtio_blk_handle_output() is called from a vCPU thread before the
VIRTIO Device Status transitions to DRIVER_OK. In that case we need to
self-trigger the ioeventfd so that the kick handled by the vCPU thread
causes the vq AioContext thread to take over handling the request(s).

ea0736d7f8 virtio-blk: tolerate failure to set BlockBackend AioContext
We no longer rely on setting the AioContext since the block layer
IO_CODE APIs can be called from any thread. Now it's just a hint to help
block jobs and other operations co-locate themselves in a thread with
the guest I/O requests. Keep going if setting the AioContext fails.
