'remotes/berrange/tags/hmp-x-qmp-620-pull-request' into staging
Initial conversion of HMP debugging commands to QMP
This introduces a new policy that all HMP commands will be converted to
have QMP equivalents, marked unstable if no formal QAPI modelling is
intended to be done.
New unstable commands are added as follows:
- HMP "info roms" => QMP "x-query-roms"
- HMP "info profile" => QMP "x-query-profile"
- HMP "info numa" => QMP "x-query-numa"
- HMP "info usb" => QMP "x-query-usb"
- HMP "info rdma" => QMP "x-query-rdma"
- HMP "info ramblock" => QMP "x-query-ramblock"
- HMP "info irq" => QMP "x-query-irq"
- HMP "info jit" => QMP "x-query-jit"
- HMP "info opcount" => QMP "x-query-opcount"

When we first stated the COLO, the last-mode is as follows:
{ "execute": "query-colo-status" }
{"return": {"last-mode": "primary", "mode": "primary", "reason": "none"}}
The last-mode is unreasonable. After the patch, will be changed to the
following:
{ "execute": "query-colo-status" }

The root cause is that we still want to shutdown the from_dst_file in
migrate_fd_cancel() after qemu_close in colo_process_checkpoint().
So, we should set the s->rp_state.from_dst_file = NULL after
qemu_close().

abort after logging a message. Since singals aren't supported here

Apple's Hypervisor.Framework forwards cache operations as MMIO traps
into user space. For MMIO however, these have no meaning: There is no
cache attached to them.
So let's just treat cache data exits as nops.
This fixes OpenBSD booting as guest.

Since commit d8fb7d0969d5 ("vl: switch -M parsing to keyval"), machine
parameter definitions cannot use underscores, because keyval_dashify()
transforms them to dashes and the parser doesn't find the parameter.
This affects option default_bus_bypass_iommu which was introduced in the
same release:
$ qemu-system-aarch64 -M virt,default_bus_bypass_iommu=on
qemu-system-aarch64: Property 'virt-6.1-machine.default-bus-bypass-iommu' not found
Rename the parameter to "default-bus-bypass-iommu". Passing
"default_bus_bypass_iommu" is still valid since the underscore are
transformed automatically.
Fixes: 6d7a85483a06 ("hw/arm/virt: Add default_bus_bypass_iommu machine option")

Cortex-M CPUs with MVE should advertise this fact to gdb, using the
org.gnu.gdb.arm.m-profile-mve XML feature, which defines the VPR
register. Presence of this feature also tells gdb to create
pseudo-registers Q0..Q7, so we do not need to tell gdb about them
separately.
Note that unless you have a very recent GDB that includes this fix:
http://patches-tcwg.linaro.org/patch/58133/ gdb will mis-print the
individual fields of the VPR register as zero (but showing the whole
thing as hex, eg with "print /x $vpr" will give the correct value).

Without this the struct has the wrong size: sizeof() evaluates
to 16 instead of 13. In most cases the bug is hidden by the
fact that guests submits a buffer which is exactly 13 bytes
long, so the padding added by the compiler is simply ignored.
But sometimes guests submit a larger buffer and expect a short
transfer, which does not work properly with the wrong struct
size.

This is a bugfix that stretches all the way back to January 2020,
where I initially introduced this problem and potential solutions.
A quick recap of the issue: QEMU did not sync up with the monitors
refresh rate causing the VM to render frames that were NOT displayed
to the user. That "fix" allowed QEMU to obtain the screen refreshrate
information from the system using GDK API's and was for GTK only.
Well, I'm back with the same issue again. But this time on Wayland.
And I did NOT realize there was YET another screen refresh rate
function, this time for Wayland specifically. Thankfully the fix was
simple and without much hassle.
Thanks,
Nikola
PS: It seems that my patch has gone missing from the mailing list,
hence I'm sending it again. Sorry for any inconveniences.
