A number of devices crash this way:
* acpi-ged (aarch64 arm i386 loongarch64 x86_64)
* fsl-imx6 (aarch64 arm)
* fsl-imx7 (aarch64 arm)
* fsl-imx8mp (aarch64)
* microchip.pfsoc (riscv64)
* riscv.sifive.e.soc (riscv32 riscv64)
* xlnx-zynqmp (aarch64)
Largely speaking these are pretty useless to try to create on
the command line, of course...
Agreed, but note that you can also query help for non-user-creatable devices
normally, e.g.:
$ ./qemu-system-x86_64 -device port92
qemu-system-x86_64: -device port92: Parameter 'driver' expects a pluggable
device type
$ ./qemu-system-x86_64 -device port92,help
port92 options:
a20[0]=<link<irq>>
port92[0]=<child<memory-region>>
... so we likely should fix the crashes anyway, even if we decide to mark
the devices with user_creatable = false.
