[Qemu-devel] [PATCH 03/17] ppc: Add a bunch of hypervisor SPRs to Book3s |
|
Date: |
Mon, 14 Mar 2016 17:56:26 +0100 |
From: Benjamin Herrenschmidt <address@hidden>
We don't give them a KVM reg number to most of the registers yet as no
current KVM version supports HV mode. For DAWR and DAWRX, the KVM reg
number is needed since this register can be set by the guest via the
H_SET_MODE hypercall.

[clg: squashed in patch 'ppc: Add KVM numbers to some P8 SPRs' and
changed the commit log with a proposal of Thomas Huth ]
