Cornelia Huck April 24, 2020, 9:03 a.m. UTC
Add 5.1 machine types for arm/i440fx/q35/s390x/spapr.

Signed-off-by: Cornelia Huck <cohuck@redhat.com>
---

Still keeping the default cpu model version on x86 at v1.

I'll queue this to my s390-next branch, as I'm planning to send a pull
req as soon as 5.0 is out; if someone else wants to queue this, we'll
figure it out :)

As spotted by patchew we need { TYPE_TPM_TIS_SYSBUS, "ppi", "false" } to
be applied for all machine types 5_0 onwards as our tpm-tis-device does
not support PPI. So I guess we need to move compat[] declaration outside
of virt_machine_5_0_options and call
"compat_props_add(mc->compat_props, compat, G_N_ELEMENTS(compat));"
for each  virt_machine_5_*_options? Or is a misuse of compats?

Thanks

Ah, that was the error (I could not really make sense of it).

So, if I understand it correctly, ppi needs to be disabled for all virt
machines. I think the correct way to do this would be to add the
"compat" prop in virt_machine_class_init() (even if it is not strictly
compat, as it always needs to be disabled). It can be removed there and
added to a compat machine should support be added in the future.

Or does anyone have a better idea?

ppi property of tpm-tis-sysbus device needs to be disabled for all virt
machines whose version >= 5.0. tpm-tis-sysbus device is supported from
5.0 onwards.

Looking again at the code, I should rather set the default value of the
ppi property to false in tpm_tis_sysbus_properties. Before we shared the
same device with x86, hence the compat but now we have a separate one. I
guess that should work directly without the pain of that compat :-( Let
me check ...

Thanks

Eric

It would probably be ok to set for all versions; if the device is not
available, a compat entry should not hurt.

Yes, that seems like a better solution.
