Isaku Yamahata 14a868c626 exec/memory: Add symbol for the min value of memory listener priority
Add MEMORY_LISTNER_PRIORITY_MIN for the symbolic value for the min value of
the memory listener instead of the hard-coded magic value 0.  Add explicit
initialization.

No functional change intended.

Zhao Liu db5a06b3a2 target/i386/WHPX: Fix error message when fail to set ProcessorCount
003f230e37 ("machine: Tweak the order of topology members in struct
CpuTopology") changes the meaning of MachineState.smp.cores from "the
number of cores in one package" to "the number of cores in one die"
and doesn't fix other uses of MachineState.smp.cores. And because of
the introduction of cluster, now smp.cores just means "the number of
cores in one cluster". This clearly does not fit the semantics here.

And before this error message, WHvSetPartitionProperty() is called to
set prop.ProcessorCount.

So the error message should show the prop.ProcessorCount other than
"cores per cluster" or "cores per package".

Since MinGW commit 395dcfdea ("rename hyper-v headers and def

got respectively renamed as winhvplatform.h / winhvemulation.h.

The mingw64-headers package included in the Fedora version we
use for CI does include this commit; and meson fails to detect
these present-but-renamed headers while cross-building (on
case-sensitive filesystems).

Use the renamed header in order to detect and successfully
cross-build with the WHPX accelerator.

Note, on Windows hosts, the libraries are still named as
WinHvPlatform.dll and WinHvEmulation.dll, so we don't bother
renaming the definitions used by load_whp_dispatch_fns() in
target/i386/whpx/whpx-all.c.

Ani Sinha ca3fcdeeee net/vhost-net: do not assert on null pointer return from tap_get_vhost_net()
When 'vhost=off' or no vhost specific options at all are passed for the tap
net-device backend, tap_get_vhost_net() can return NULL. The function
net_init_tap_one() does not call vhost_net_init() on such cases and therefore
vhost_net pointer within the tap device state structure remains NULL. Hence,
assertion here on a NULL pointer return from tap_get_vhost_net() would not be
correct. Remove it and fix the crash generated by qemu upon initialization in
the following call chain :

qdev_realize() -> pci_qdev_realize() -> virtio_device_realize() ->
virtio_bus_device_plugged() -> virtio_net_get_features() -> get_vhost_net()

Henrik Carlqvist 6b90a4cdc0 escc: emulate dip switch language layout settings on SUN keyboard
SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
and uses that value to select keyboard layout.  Also the SUN bios like the one
in the file ss5.bin uses this value to support at least some keyboard layouts.
However, the OpenBIOS provided with qemu is hardcoded to always use an US
keyboard layout.

Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
this patch uses a command line switch like
"-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
used to lookup values from arguments like:

-global escc.chnA-sunkbd-layout=fr
-global escc.chnA-sunkbd-layout=es

But the patch also accepts numeric dip switch values directly:

-global escc.chnA-sunkbd-layout=0x2b
-global escc.chnA-sunkbd-layout=43

Both values above are the same and select swedish keyboard as explained in
table 3-15 at
https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html

Unless you want to do a full Solaris installation but happen to have
access to a Sun bios file, the easiest way to test that the patch works
is to:

qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin

If you already happen to have a Solaris installation in a qemu disk image
file you can easily try different keyboard layouts after this patch is
applied.

Richard Henderson 633c42834c target/sparc: Introduce DYNAMIC_PC_LOOKUP
Create a new artificial "next pc" which also indicates
that nothing has changed within the cpu state which
requires returning to the main loop.

Pipe this new value though all pc/npc checks.
Do not produce this new value yet.

During translation, npc == address, DYNAMIC_PC, or JUMP_PC.
It is only the encoding between here and sparc_restore_state_to_opc
that considers JUMP_PC to be a bit within a larger value.

This reverts commit 1881f336a3.

This commit breaks "-drive if=pflash,readonly=on,file=image.iso".  It
claims to merely replace an open-coded version of blk_name() by a
call, but that's not the case.  Sorry for the inconvenience!

Minwoo Im cab1da59c2 hw/nvme: consider COPY command in nvme_aio_err
If we don't have NVME_CMD_COPY consideration in the switch statement in
nvme_aio_err(), it will go to have NVME_INTERNAL_DEV_ERROR and
`req->status` will be ovewritten to it.  During the aio context, it
might set the NVMe status field like NVME_CMD_SIZE_LIMIT, but it's
overwritten in the nvme_aio_err().

Add consideration for the NVME_CMD_COPY not to overwrite the status at
the end of the function.

Paolo Bonzini 17362398ee block: use bdrv_co_debug_event in coroutine context
bdrv_co_debug_event was recently introduced, with bdrv_debug_event
becoming a wrapper for use in unknown context.  Because most of the
time bdrv_debug_event is used on a BdrvChild via the wrapper macro
BLKDBG_EVENT, introduce a similar macro BLKDBG_CO_EVENT that calls
bdrv_co_debug_event, and switch whenever possible.
