The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
virt_cpu_irq_init() is wrong that way: it passes &err to
hotplug_handler_plug() twice. If both calls failed, this could trip
error_setv()'s assertion. Moreover, if just one fails, the Error
object leaks. Fortunately, these calls can't actually fail.
Messed up in commit 50ebc3fc47f7 (hw/intc/loongarch_ipi: Notify ipi
object when cpu is plugged) and commit 087a23a87c57
(hw/intc/loongarch_extioi: Use cpu plug notification).
Clean this up by passing &error_abort instead.

Currently we handle the 'dumpdtb' machine sub-option ad-hoc in every
board model that has an FDT. It's up to the board code to make sure
it calls qemu_fdt_dumpdtb() in the right place.
This means we're inconsistent and often just ignore the user's
command line argument:
* if the board doesn't have an FDT at all
* if the board supports FDT, but there happens not to be one
present (usually because of a missing -fdt option)
This isn't very helpful because it gives the user no clue why their
option was ignored.
However, in order to support the QMP/HMP dumpdtb commands we require
now that every FDT machine stores a pointer to the FDT in
MachineState::fdt. This means we can handle -machine dumpdtb
centrally by calling the qmp_dumpdtb() function, unifying its
handling with the QMP/HMP commands. All the board code calls to
qemu_fdt_dumpdtb() can then be removed.
For this commit we retain the existing behaviour that if there
is no FDT we silently ignore the -machine dumpdtb option.

hw/char/serial currently contains the implementation of both TYPE_SERIAL and

class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.
The includes and the dependencies have been converted mechanically except in the

Now, only hw/char makes direct use of TYPE_SERIAL:

If the FDT contains /chosen/rng-seed, then the Linux RNG will use it to

For virtio VGA deivce libvirt will select VIRTIO_VGA firstly rather than
VIRTIO_GPU, VIRTIO_VGA device supports frame buffer however it requires
legacy VGA compatible support. Frame buffer area 0xa0000 -- 0xc0000
conflicts with low memory area 0 -- 0x10000000.
Here remove default support for VIRTIO_VGA device, VIRTIO_GPU is prefered
on LoongArch system. For frame buffer video card support, standard VGA can
be used.

Loongarch IPI inherits from class LoongsonIPICommonClass, and it
only contains Loongarch 3A5000 virt machine specific interfaces,
rather than mix different machine implementations together.
