[PATCH v2 0/2] spapr: Make the nested code TCG only

Posted by Fabiano Rosas 3 years, 10 months ago

The spapr virtual hypervisor implementation of the nested KVM API
depends on the first level guest to be emulated by TCG. So move the
whole code under CONFIG_TCG.

v2:

- Created hypercall_register_nested instead of reusing
  hypercall_register_softmmu;

- Rearranged the ifdef a bit to keep the hypercall_register_*
  functions closer;

- Dropped the more paranoid patch that checked for KVM at every
  call. I couldn't convince myself anymore that it was necessary.

v1:

  spapr: Move hypercall_register_softmmu
  spapr: Move nested KVM hypercalls under a TCG only config.
