Ping, Alex.G and Alex.W. Could you please take a look on this when
you have available bandwidth? Thanks in advance for your time :-)
The series of patches intends to support EEH for PCI devices, which are

The address of passed PCI devices (domain:bus:slot:func) might be
quite different from the perspective of host and guest. We have to
trace the address mapping so that we can emulate EEH RTAS requests
from guest. The patch introduces additional fields to

Originally, syscall ppc_rtas() can be used to invoke RTAS call from

to the system for testing purpose. The patch intends to extend the
syscall to support both pSeries and PowerNV platform.

If we're running PowerNV platform, ppc_firmware() will be directed
to ppc_call_opal() where we can call to OPAL API accordingly. In
ppc_call_opal(), the input argument are parsed out and call to
appropriate OPAL API to handle that. Each request passed to the

For now, we just support PCI error injection. We

POWER8 introduces transactional memory which brings along a number of new

Implementing all of those is a pretty big headache, so for now let's at least

I don't see the point of VFIO knowing about guest addresses. They are
not unique across a system and the whole idea that a VFIO device has to
be owned by a guest is also pretty dubious.
I suppose what you really care about here is
