When pel panning is active, one more byte is read from each of the VGA
memory planes. This has to be accounted in the computation of region_end,
otherwise vga_draw_graphic() fails an assertion:
qemu-system-i386: ../system/physmem.c:946: cpu_physical_memory_snapshot_get_dirty: Assertion `start + length <= snap->end' failed.

Move the computation of region_start and region_end after the value of
"bits" is known. This makes it possible to distinguish modes that
support horizontal pel panning from modes that do not.

There are two sets of conditionals using the shift control bits: one to
verify the palette and adjust disp_width, one to compute the "v" and
"bits" variables. Merge them into one, with the extra benefit that
we now have the "bits" value available early and can use it to
compute region_end.

Coverity complains that the check introduced in commit 3f934817 suggests
that qiov could be NULL and we dereference it before reaching the check.

Similarly to commit 9de9fa5cf2 ("hw/arm/smmu-common: Avoid using
inlined functions with external linkage"):
None of our code base require / use inlined functions with external
linkage. Some places use internal inlining in the hot path. These
two functions are certainly not in any hot path and don't justify
any inlining, so these are likely oversights rather than intentional.
Fix:

pointer size is always 64-bit, which breaks on 32-bit :
../tests/qtest/stm32l4x5_gpio-test.c: In function ‘test_gpio_output_mode’:
../tests/qtest/stm32l4x5_gpio-test.c:272:25: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
272 | unsigned int pin = ((uint64_t)data) & 0xF;
| ^
../tests/qtest/stm32l4x5_gpio-test.c:273:22: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
273 | uint32_t gpio = ((uint64_t)data) >> 32;
| ^
To fix, improve the mangling of the GPIO address and pin number fields
by using GPIO_SIZE so that the resulting value fits in a 32-bit pointer.
While at it, include some helpers to hide the details.

If the group of the highest priority pending interrupt is disabled
via ICC_IGRPEN*, the ICC_HPPIR* registers should return
INTID_SPURIOUS, not the interrupt ID. (See the GIC architecture
specification pseudocode functions ICC_HPPIR1_EL1[] and
HighestPriorityPendingInterrupt().)
Make HPPIR reads honour the group disable, the way we already do
when determining whether to preempt in icc_hppi_can_preempt().

The HSTR_EL2 register allows the hypervisor to trap AArch32 EL1 and
EL0 accesses to cp15 registers. We incorrectly implemented this so
they trap to EL1 when we detect the need for a HSTR trap at code
generation time. (The check in access_check_cp_reg() which we do at
runtime to catch traps from EL0 is correctly routing them to EL2.)
Use the correct target EL when generating the code to take the trap.

This fixes the invalid bInterfaceProtocol value 0x04 in the USB audio
AudioControl descriptors. It should be zero. While Linux and Windows
forgive this error, macOS 14 Sonoma does not. The usb-audio device does
not appear in macOS sound settings even though the device is recognized
and shows up in USB system information. According to the USB audio class
specs 1.0-4.0, valid values are 0x00, 0x20, 0x30 and 0x40. (Note also
that Linux prints the warning "unknown interface protocol 0x4, assuming
v1", but then proceeds as if the value was zero.)
This also fixes the invalid wTotalLength value in the multi-channel
setup AudioControl interface header descriptor (used when multi=on
and out.mixing-engine off). The combined length of all the descriptors
there add up to 0x37, not 0x38. In Linux, "lsusb -D ..." displays
incomplete descriptor information when this length is incorrect.

There are several places where postcopy_start() fails without setting
errp. This can cause a null pointer de-reference, as in case of error,
the caller of postcopy_start() copies/prints the error set in errp.
Fix it by setting errp in all of postcopy_start() error paths.

After commit 9425ef3f990a ("migration: Use migrate_has_error() in
close_return_path_on_source()"), close_return_path_on_source() assumes
that migration error is set if an error occurs during migration.
This may not be true if migration errors in migration_completion(). For
example, if qemu_savevm_state_complete_precopy() errors, migration error
will not be set.
This in turn, will cause a migration hang bug, similar to the bug that
was fixed by commit 22b04245f0d5 ("migration: Join the return path
thread before releasing to_dst_file"), as shutdown() will not be issued
for the return-path channel.
Fix it by ensuring migration error is set in case of error in
migration_completion().

If the time is wrong, setup-alpine SSL certificate checks can fail.
setup-alpine is used to bring up the network, but it doesn't seem
to to set NTP time before the failing SSL checks. This test has
recently started failing presumably because the default time has
now fallen too far behind.

Hardware clears the MSR[ME] bit when delivering a machine check
interrupt, so that is what QEMU does.
The spapr environment runs in supervisor mode though, and receives
machine check interrupts after they are processed by the hypervisor,
and MSR[ME] must always be enabled in supervisor mode (otherwise it
could checkstop the system). So MSR[ME] must not be cleared when
delivering machine checks to the supervisor.
The fix to prevent supervisor mode from modifying MSR[ME] also
prevented it from re-enabling the incorrectly cleared MSR[ME] bit
when returning from handling the interrupt. Before that fix, the
problem was not very noticable with well-behaved code. So the
Fixes tag is not strictly correct, but practically they go together.
Found by kvm-unit-tests machine check tests (not yet upstream).

The GDB server protocol assigns an arbitrary numbering of the SPRs.
We track this correspondence on each SPR with gdb_id, using it to
resolve any SPR requests GDB makes.
Early on we generate an XML representation of the SPRs to give GDB,
including this numbering. However the XML is cached globally, and we
skip setting the SPR gdb_id values on subsequent threads if we detect
it is cached. This causes QEMU to fail to resolve SPR requests against
secondary CPUs because it cannot find the matching gdb_id value on that
thread's SPRs.
This is a minimal fix to first assign the gdb_id values, then return
early if the XML is cached. Otherwise we generate the XML using the
now already initialised gdb_id values.
Fixes: 1b53948ff8f7 ("target/ppc: Use GDBFeature for dynamic XML")

The DEXCR emulation was recently changed to a 32-bit register, possibly
because it does have a 32-bit read-only view. It is a full 64-bit
SPR though, so use the corresponding 64-bit write functions.

"sysemu/tcg.h" declares tcg_enabled(), and is implicitly included.
Include it explicitly to avoid the following error when refactoring
headers:
hw/ppc/spapr.c:2612:9: error: call to undeclared function 'tcg_enabled'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

Using log_pc produces the pc at the beginning of TB,
not the actual pc installed by cpu_restore_state_from_tb,
which could be any of the guest instructions within TB.

The 'sign' computation is attempting to locate the sign bit that has
been repeated, so that we can test if that bit is known zero. That
computation can be zero if there are no known sign repetitions.
