KVM: s390: SIE considerations for AP Queue virtualization
The Crypto Control Block (CRYCB) is referenced by the SIE state description and controls KVM guest access to the Adjunct Processor (AP) adapters, usage domains and control domains. This patch defines the AP control blocks to be used for controlling guest access to the AP adapters and domains.
