[PATCH 0/4] Allow setting RAPL_DIS during SNP_INIT_EX

[Tycho Andersen <tycho@kernel.org>]

From: "Tycho Andersen (AMD)" <tycho@kernel.org>

There was support for setting the policy bit, but not the flag during
SNP_INIT_EX, which meant VM creation would always fail. Plumb a module
parameter for setting the flag during SNP_INIT_EX.

Also clean up some selftests and add a smoke test for RAPL_DISABLE
when the module parameter is set appropriately.

Tycho Andersen (AMD) (4):
  selftests/kvm: allow retrieving underlying SEV firmware error
  selftests/kvm: check that SEV-ES VMs are allowed in SEV-SNP mode
  crypto/ccp: support setting RAPL_DIS in SNP_INIT_EX
  selftests/kvm: smoke test support for RAPL_DIS
