Re: [RFC PATCH v2 0/5] Port PPC64/PowerNV MMU tests to QEMU

[Cédric Le Goater]

Hello Leandro,

I think we should start looking at semihosting like Richard proposed
and for it, rework the QEMU attn implementation or may be use a special
form of scv.

It should not change too much the tests, only exit and output which
would remove the dependency on the platform console. In the long run,
it looks like  a good investment for more low level tests.

Thanks,

C.
