[PATCH v2 0/9] ppc: nested KVM HV for spapr virtual hypervisor

Posted by Nicholas Piggin 2 years, 2 months ago

This should account for AFAIKS all comments, except maybe some
about naming.

Changes since v1:
- Per-CPU spapr nested state moved to SpaprCpuState from PowerPCCPU.
- address_space_map ops are used, small rearrangement to make any
  given access region store-only or load-only.
- Some style, naming, etc cleanups and fixes.

Hopefully I didn't miss anything.

Thanks,
Nick

We can address migration aspects with followups.

Applied for ppc-7.0

Thanks,
