H A D | ultravisor.c | bb04ffe85eebebd64d5e673a9434d968e80f3aa1 Thu Aug 22 05:48:34 CEST 2019 Claudio Carvalho <cclaudio@linux.ibm.com> powerpc/powernv: Introduce FW_FEATURE_ULTRAVISOR
In PEF enabled systems, some of the resources which were previously hypervisor privileged are now ultravisor privileged and controlled by the ultravisor firmware.
This adds FW_FEATURE_ULTRAVISOR to indicate if PEF is enabled.
The host kernel can use FW_FEATURE_ULTRAVISOR, for instance, to skip accessing resources (e.g. PTCR and LDBAR) in case PEF is enabled.
