A misspelled condition in xen_native.h is hiding a bug in the enablement of
Xen for qemu-system-aarch64. The bug becomes apparent when building for
Xen 4.18.
While the i386 emulator provides the xenpv machine type for multiple architectures,
and therefore can be compiled with Xen enabled even when the host is Arm, the
opposite is not true: qemu-system-aarch64 can only be compiled with Xen support
enabled when the host is Arm.
Expand the computation of accelerator_targets['CONFIG_XEN'] similar to what is
already there for KVM.

Commit 7191f24c7f ("accel/kvm/kvm-all: Handle register access errors")
added error checking for KVM_SET_SREGS/KVM_SET_SREGS2. In doing so, it
exposed a long-running bug in current KVM support for SEV-ES where the
kernel assumes that MSR_EFER_LMA will be set explicitly by the guest
kernel, in which case EFER write traps would result in KVM eventually
seeing MSR_EFER_LMA get set and recording it in such a way that it would
be subsequently visible when accessing it via KVM_GET_SREGS/etc.
However, guest kernels currently rely on MSR_EFER_LMA getting set
automatically when MSR_EFER_LME is set and paging is enabled via
CR0_PG_MASK. As a result, the EFER write traps don't actually expose the
MSR_EFER_LMA bit, even though it is set internally, and when QEMU
subsequently tries to pass this EFER value back to KVM via
KVM_SET_SREGS* it will fail various sanity checks and return -EINVAL,
which is now considered fatal due to the aforementioned QEMU commit.
This can be addressed by inferring the MSR_EFER_LMA bit being set when
paging is enabled and MSR_EFER_LME is set, and synthesizing it to ensure
the expected bits are all present in subsequent handling on the host
side.
Ultimately, this handling will be implemented in the host kernel, but to
avoid breaking QEMU's SEV-ES support when using older host kernels, the
same handling can be done in QEMU just after fetching the register
values via KVM_GET_SREGS*. Implement that here.

hw/ufs: avoid generating the same ID string for different LU devices
Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
QEMU would not start when trying to create two UFS host controllers and
a UFS logical unit for each with the following options:
-device ufs,id=bus0 \
-device ufs-lu,drive=drive1,bus=bus0,lun=0 \
-device ufs,id=bus1 \
-device ufs-lu,drive=drive2,bus=bus1,lun=0 \
This is because the same ID string ("0:0:0/scsi-disk") is generated
for both UFS logical units.
To fix this issue, prepend the parent pci device's path to make
the ID string unique.

KVM_RISCV_GET_CSR() and KVM_RISCV_SET_CSR() use an 'int ret' variable
that is used to do an early 'return' if ret > 0. Both are being called
in functions that are also declaring a 'ret' integer, initialized with
'0', and this integer is used as return of the function.
The result is that the compiler is less than pleased and is pointing
shadowing errors:
../target/riscv/kvm/kvm-cpu.c: In function 'kvm_riscv_get_regs_csr':
../target/riscv/kvm/kvm-cpu.c:90:13: error: declaration of 'ret' shadows a previous local [-Werror=shadow=compatible-local]

| ^~~

539 | KVM_RISCV_GET_CSR(cs, env, sstatus, env->mstatus);
| ^~~~~~~~~~~~~~~~~
../target/riscv/kvm/kvm-cpu.c:536:9: note: shadowed declaration is here
536 | int ret = 0;

| ^~~~~~~~~~~~~~~~~
../target/riscv/kvm/kvm-cpu.c:553:9: note: shadowed declaration is here
553 | int ret = 0;
| ^~~
The macros are doing early returns for non-zero returns and the local
'ret' variable for both functions is used just to do 'return 0', so
remove them from kvm_riscv_get_regs_csr() and kvm_riscv_put_regs_csr()
and do a straight 'return 0' in the end.
For good measure let's also rename the 'ret' variables in
KVM_RISCV_GET_CSR() and KVM_RISCV_SET_CSR() to '_ret' to make them more
resilient to these kind of errors.

Commit 6f189a08c1 ("ui/gtk-egl: Check EGLSurface before doing
scanout") introduced a regression when QEMU is running with a
virtio-gpu-gl-device on a host under X11. After the guest has
initialized the virtio-gpu-gl-device, the guest screen only
shows "Display output is not active.".
Commit 6f189a08c1 moved all function calls in
gd_egl_scanout_texture() to a code path which is only called
once after gd_egl_init() succeeds in gd_egl_scanout_texture().
Move all function calls in gd_egl_scanout_texture() back to
the regular code path so they get always called if one of the
gd_egl_init() calls was successful.

`kvm_enabled()` is compiled down to `0` and short-circuit logic is
used to remove references to undefined symbols at the compile stage.
Some build configurations with some compilers don't attempt to
simplify this logic down in some cases (the pattern appears to be
that the literal false must be the first term) and this was causing
some builds to emit references to undefined symbols.
An example of such a configuration is clang 16.0.6 with the following
configure: ./configure --enable-debug --without-default-features
--target-list=x86_64-softmmu --enable-tcg-interpreter

QEMU crashes on exit when a virtio-sound device has failed to
realise. Its vmstate field was not cleaned up properly with
qemu_del_vm_change_state_handler().
This patch changes the realize() order as
1. Validate the given configuration values (no resources allocated
by us either on success or failure)
2. Try AUD_register_card() and return on failure (no resources allocated
by us on failure)
3. Initialize vmstate, virtio device, heap allocations and stream
parameters at once.
If error occurs, goto error_cleanup label which calls
virtio_snd_unrealize(). This cleans up all resources made in steps
1-3.

When dumping table blobs using rebuild-expected-aml.sh, table blobs from all
test variants are dumped regardless of whether there are any actual changes to
the tables or not. This creates lot of new files for various test variants that
are not part of the git repository. This is because we do not check in all table
blobs for all test variants into the repository. Only those blobs for those
variants that are different from the generic test-variant agnostic blob are
checked in.
This change makes the test smarter by checking if at all there are any changes
in the tables from the checked-in gold master blobs and take actions
accordingly.
When there are no changes:
- No new table blobs would be written.
- Existing table blobs will be refreshed (git diff will show no changes).
When there are changes:
- New table blob files will be dumped.
- Existing table blobs will be refreshed (git diff will show that the files
changed, asl diff will show the actual changes).
When new tables are introduced:
- Zero byte empty file blobs for new tables as instructed in the header of
bios-tables-test.c will be regenerated to actual table blobs.
This would make analyzing changes to tables less confusing and there would
be no need to clean useless untracked files when there are no table changes.

It doesn't make sense to have two classes of flaky tests. While it may
take the constrained environment of CI to trigger failures easily it
doesn't mean they don't occasionally happen on developer machines. As
CI is the gating factor to passing there is no point developers
running the tests locally anyway unless they are trying to fix things.
While we are at it update the language in the docs to discourage the
QEMU_TEST_FLAKY_TESTS becoming a permanent solution.

migration: free 'saddr' since be no longer used
migration/multifd: Stop setting p->ioc before connecting

The machine uses a modified U-Boot under GPL license but the sources
of it are lost with only a binary available so it cannot be included
in QEMU. Allow running without the firmware image which can be used
when calling a boot loader directly and thus simplifying booting
guests. We need a small routine that AmigaOS calls from ROM which is
added in this case to allow booting AmigaOS without external firmware
image.

Since socket_parse() will allocate memory for 'saddr',and its value
will pass to 'addr' that allocated by migrate_uri_parse(),
then 'saddr' will no longer used,need to free.
But due to 'saddr->u' is shallow copying the contents of the union,
the members of this union containing allocated strings,and will be used after that.
So just free 'saddr' itself without doing a deep free on the contents of the SocketAddress.
