In commit 6f974c843c ("gtk: overwrite the console.c char driver"), I
shared the VC console parse handler with GTK. And later on in commit
d8aec9d9 ("display: add -display spice-app launching a Spice client"),
I also used it to handle spice-app VC.
This is not necessary, the VC console options (width/height/cols/rows)
are specific, and unused by tty-level GTK/Spice VC.
This is not a breaking change, as those options are still being parsed
by QAPI ChardevVC. Adjust the documentation about it.

This will stop linking softmmu-specific os_parse_cmd_args() into every
qemu executable which happens to use other functions from os-posix.c,
such as os_set_line_buffering() or os_setup_signal_handling().
Also, since there's no win32-specific options, *all* option parsing is
now done in softmmu/vl.c:qemu_init(), which is easier to read without
extra indirection, - all options are in the single function now.
This effectively reverts commit 59a5264b99.

Per the latest HAXM release (v7.8 [*]), the latest QEMU supported
is v7.2:
Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0.
The next commit (https://github.com/intel/haxm/commit/da1b8ec072)
added:
HAXM v7.8.0 is our last release and we will not accept
pull requests or respond to issues after this.
It became very hard to build and test HAXM. Its previous
maintainers made it clear they won't help. It doesn't seem to be
a very good use of QEMU maintainers to spend their time in a dead
project. Save our time by removing this orphan zombie code.

The IoTKit, SSE200 and SSE300 all default to 8 MPU regions. The
MPS2/MPS3 FPGA images don't override these except in the case of
AN547, which uses 16 MPU regions.
Define properties on the ARMSSE object for the MPU regions (using the
same names as the documented RTL configuration settings, and
following the pattern we already have for this device of using
all-caps names as the RTL does), and set them in the board code.
We don't actually need to override the default except on AN547,
but it's simpler code to have the board code set them always
rather than tracking which board subtypes want to set them to
a non-default value separately from what that value is.
Tho overall effect is that for mps2-an505, mps2-an521 and mps3-an524
we now correctly use 8 MPU regions, while mps3-an547 stays at its
current 16 regions.
It's possible some guest code wrongly depended on the previous
incorrectly modeled number of memory regions. (Such guest code
should ideally check the number of regions via the MPU_TYPE
register.) The old behaviour can be obtained with additional
-global arguments to QEMU:
For mps2-an521 and mps2-an524:
-global sse-200.CPU0_MPU_NS=16 -global sse-200.CPU0_MPU_S=16 -global sse-200.CPU1_MPU_NS=16 -global sse-200.CPU1_MPU_S=16
For mps2-an505:
-global sse-200.CPU0_MPU_NS=16 -global sse-200.CPU0_MPU_S=16
NB that the way the implementation allows this use of -global
is slightly fragile: if the board code explicitly sets the
properties on the sse-200 object, this overrides the -global
command line option. So we rely on:
- the boards that need fixing all happen to use the SSE defaults
- we can write the board code to only set the property if it
is different from the default, rather than having all boards
explicitly set the property
- the board that does need to use a non-default value happens
to need to set it to the same value (16) we previously used
This works, but there are some kinds of refactoring of the
mps2-tz.c code that would break the support for -global here.

M-profile CPUs generally allow configuration of the number of MPU
regions that they have. We don't currently model this, so our
implementations of some of the board models provide CPUs with the
wrong number of regions. RTOSes like Zephyr that hardcode the
expected number of regions may therefore not run on the model if they
are set up to run on real hardware.
Add properties mpu-ns-regions and mpu-s-regions to the ARMV7M object,
matching the ability of hardware to configure the number of Secure
and NonSecure regions separately. Our actual CPU implementation
doesn't currently support that, and it happens that none of the MPS
boards we model set the number of regions differently for Secure vs
NonSecure, so we provide an interface to the boards and SoCs that
won't need to change if we ever do add that functionality in future,
but make it an error to configure the two properties to different
values.
(The property name on the CPU is the somewhat misnamed-for-M-profile
"pmsav7-dregion", so we don't follow that naming convention for
the properties here. The TRM doesn't say what the CPU configuration
variable names are, so we pick something, and follow the lowercase
convention we already have for properties here.)

The functions qemu_get_timedate() and qemu_timedate_diff() take
and return a time offset as an integer. Coverity points out that
means that when an RTC device implementation holds an offset
as a time_t, as the m48t59 does, the time_t will get truncated.
(CID 1507157, 1517772).
The functions work with time_t internally, so make them use that type
in their APIs.
Note that this won't help any Y2038 issues where either the device
model itself is keeping the offset in a 32-bit integer, or where the
hardware under emulation has Y2038 or other rollover problems. If we
missed any cases of the former then hopefully Coverity will warn us
about them since after this patch we'd be truncating a time_t in
assignments from qemu_timedate_diff().)

The SRC device is normally used to start the secondary CPU.
When running Linux directly, QEMU is emulating a PSCI interface that UBOOT
is installing at boot time and therefore the fact that the SRC device is
unimplemented is hidden as Qemu respond directly to PSCI requets without
using the SRC device.
But if you try to run a more bare metal application (maybe uboot itself),
then it is not possible to start the secondary CPU as the SRC is an
unimplemented device.
This patch adds the ability to start the secondary CPU through the SRC
device so that you can use this feature in bare metal applications.

When target image is using subclusters, and we align the request during
copy-on-read, it makes sense to align to subcluster_size rather than
cluster_size. Otherwise we end up with unnecessary allocations.
This commit renames bdrv_round_to_clusters() to bdrv_round_to_subclusters()
and utilizes subcluster_size field of BlockDriverInfo to make necessary
alignments. It affects copy-on-read as well as mirror job (which is
using bdrv_round_to_clusters()).
This change also fixes the following bug with failing assert (covered by
the test in the subsequent commit):

Using "-device virtio-gpu,blob=true" currently does not work on big
endian hosts (like s390x). The guest kernel prints an error message
like:
[drm:virtio_gpu_dequeue_ctrl_func [virtio_gpu]] *ERROR* response 0x1200 (command 0x10c)
and the display stays black. When running QEMU with "-d guest_errors",
it shows an error message like this:
virtio_gpu_create_mapping_iov: nr_entries is too big (83886080 > 16384)
which indicates that this value has not been properly byte-swapped.
And indeed, the virtio_gpu_create_blob_bswap() function (that should
swap the fields in the related structure) fails to swap some of the
entries. After correctly swapping all missing values here, too, the
virtio-gpu device is now also working with blob=true on s390x hosts.

kvm_arch_get_default_type() returns the default KVM type. This hook is
particularly useful to derive a KVM type that is valid for "none"
machine model, which is used by libvirt to probe the availability of
KVM.
For MIPS, the existing mips_kvm_type() is reused. This function ensures
the availability of VZ which is mandatory to use KVM on the current
QEMU.

Rather than using a zero tuple to end the table, use a macro
to apply ARRAY_SIZE and pass that on to the convert functions.
This fixes two bugs in which the conversion functions required
that both the target and host masks be non-zero in order to
continue, rather than require both target and host masks be
zero in order to terminate.
This affected mmap_flags_tbl when the host does not support
all of the flags we wish to convert (e.g. MAP_UNINITIALIZED).
Mapping these flags to zero is good enough, and matches how
the kernel ignores bits that are unknown.

Calling OpenGL from different threads can have bad consequences if not
carefully reviewed. It's not generally supported. In my case, I was
debugging a crash in glDeleteTextures from OPENGL32.DLL, where I asked
qemu for gl=es, and thus ANGLE implementation was expected. libepoxy did
resolution of the global pointer for glGenTexture to the GLES version
from the main thread. But it resolved glDeleteTextures to the GL
version, because it was done from a different thread without correct
context. Oops.
Let's stick to the main thread for GL calls by using a BH.
Note: I didn't use atomics for reset_finished check, assuming the BQL
will provide enough of sync, but I might be wrong.

The first bitfield here is supposed to be used as a 64-bit equivalent
to the "uint64_t msi_addr" in the union. To make this work correctly
on big endian hosts, too, the __addr_hi field has to be part of the
bitfield, and the the bitfield members must be declared with "uint64_t"
instead of "uint32_t" - otherwise the values are placed in the wrong
bytes on big endian hosts.
Same applies to the 32-bit "msi_data" field: __resved1 must be part
of the bitfield, and the members must be declared with "uint32_t"
instead of "uint16_t".

The code already tries to do some endianness handling here, but
currently fails badly:
- While it already swaps the data when logging errors / tracing, it fails
to byteswap the value before e.g. accessing entry->irte.present
- entry->irte.source_id is swapped with le32_to_cpu(), though this is
a 16-bit value
- The whole union is apparently supposed to be swapped via the 64-bit
data[2] array, but the struct is a mixture between 32 bit values
(the first 8 bytes) and 64 bit values (the second 8 bytes), so this
cannot work as expected.
Fix it by converting the struct to two proper 64-bit bitfields, and
by swapping the values only once for everybody right after reading
the data from memory.

The QEMU CI fails in virtio-scmi test occasionally. As reported by

fails with the following error:

../../devel/qemu/tests/qtest/libqtest.c:200: kill_qemu() detected QEMU death from signal 6 (Aborted) (core dumped)
As discovered by Fabiano Rosas, the cause is a duplicate invocation of

While vu_scmi_stop calls are protected by vhost_dev_is_started()
check, it's apparently not enough. vhost-user-blk and vhost-user-gpio
use an extra protection, see f5b22d06fb (vhost: recheck dev state in
the vhost_migration_log routine) for the motivation. Let's use the
same in vhost-user-scmi, which fixes the failure above.

The TLS handshake make take some time to complete, during which time an
I/O watch might be registered with the main loop. If the owner of the
I/O channel invokes qio_channel_close() while the handshake is waiting
to continue the I/O watch must be removed. Failing to remove it will
later trigger the completion callback which the owner is not expecting
to receive. In the case of the VNC server, this results in a SEGV as
vnc_disconnect_start() tries to shutdown a client connection that is

Deciphering the hard-coded list of integer return values from
nbd_start_negotiate() will only get more confusing when adding support
for 64-bit extended headers. Better is to name things in an enum.
Although the function in question is private to client.c, putting the
enum in a public header and including an enum-to-string conversion
will allow its use in more places in upcoming patches.
The enum is intentionally laid out so that operators like <= can be
used to group multiple modes with similar characteristics, and where
the least powerful mode has value 0, even though this patch does not
exploit that. No semantic change intended.

Externally, libnbd exposed the 64-bit opaque marker for each client
NBD packet as the "cookie", because it was less confusing when
contrasted with 'struct nbd_handle *' holding all libnbd state. It
also avoids confusion between the noun 'handle' as a way to identify a
packet and the verb 'handle' for reacting to things like signals.
Upstream NBD changed their spec to favor the name "cookie" based on
libnbd's recommendations[1], so we can do likewise.

Upstream NBD now documents[1] an extension that supports 64-bit effect
lengths in requests. As part of that extension, the size of the reply
headers will change in order to permit a 64-bit length in the reply
for symmetry[2]. Additionally, where the reply header is currently 16
bytes for simple reply, and 20 bytes for structured reply; with the
extension enabled, there will only be one extended reply header, of 32
bytes, with both structured and extended modes sending identical
payloads for chunked replies.
Since we are already wired up to use iovecs, it is easiest to allow
for this change in header size by splitting each structured reply
across multiple iovecs, one for the header (which will become wider in
a future patch according to client negotiation), and the other(s) for
the chunk payload, and removing the header from the payload struct
definitions. Rename the affected functions with s/structured/chunk/
to make it obvious that the code will be reused in extended mode.
Interestingly, the client side code never utilized the packed types,
so only the server code needs to be updated.
[1] https://github.com/NetworkBlockDevice/nbd/blob/extension-ext-header/doc/proto.md
as of NBD commit e6f3b94a934
[2] Note that on the surface, this is because some future server might
permit a 4G+ NBD_CMD_READ and need to reply with that much data in one
transaction. But even though the extended reply length is widened to
64 bits, for now the NBD spec is clear that servers will not reply
with more than a maximum payload bounded by the 32-bit
NBD_INFO_BLOCK_SIZE field; allowing a client and server to mutually
agree to transactions larger than 4G would require yet another
extension.
