Re: [PATCH 0/2] P11 support for QEMU

[Cédric Le Goater]

Hello Aditya,

Please run ./scripts/get_maintainer.pl when sending a series. qemu-ppc should be
in Cc:

Briefly looking at this, please separate the changes using one patch per model,
that is : first CPU (target), LPC, OCC, PSI, SBE, PnvCore, SpaprCore. Last the
PnvChip and the machines, powernv11 and pseries. A minimum commit log describing
the HW is required. I don't see PHB6 or XIVE3. Why ?

Also, you will need an OPAL update. The above changes are pointless without it.
The minimum for now is a git commit from the opal repo, then you will need to
update QEMU with a binary.

Thanks,

C.
