[Qemu-devel] i440/piix and dynamic sysbus check

[Marc-André Lureau]

Hi,

I am working on a TPM CRB device (last sent version:
https://lists.gnu.org/archive/html/qemu-devel/2017-10/msg02014.html).
It's a sysbus device, and when starting qemu with i440, I get "Option
'-device tpm-crb' cannot be handled by this machine".

The check comes from machine_init_notify(), checking that the machine
has_dynamic_sysbus.

 Apparently, q35 supports it. But not i440. If I declare
has_dynamic_sysbus in piix, the device works fine.

Marcel, could we do something similar to piix to what you did for q35?:

    q35: allow dynamic sysbus

thanks
