2 Secure Encrypted Virtualization (SEV)
8 Secure Encrypted Virtualization (SEV) is a feature found on AMD processors.
10 SEV is an extension to the AMD-V architecture which supports running
15 The hypervisor can determine the SEV support through the CPUID
17 to SEV::
20 			Bit[1] 	indicates support for SEV
25 If support for SEV is present, MSR 0xc001_0010 (MSR_K8_SYSCFG) and MSR 0xc001_0015
36 When SEV support is available, it can be enabled in a specific VM by
37 setting the SEV bit before executing VMRUN.::
40 		Bit[1]	    1 = SEV is enabled
41 			    0 = SEV is disabled
43 SEV hardware uses ASIDs to associate a memory encryption key with a VM.
44 Hence, the ASID for the SEV-enabled guests must be from 1 to a maximum value
47 SEV Key Management
50 The SEV guest key management is handled by a separate processor called the AMD
54 information, see the SEV Key Management spec [api-spec]_
56 The main ioctl to access SEV is KVM_MEMORY_ENCRYPT_OP.  If the argument
57 to KVM_MEMORY_ENCRYPT_OP is NULL, the ioctl returns 0 if SEV is enabled
79 KVM implements the following commands to support common lifecycle events of SEV
85 The KVM_SEV_INIT command is used by the hypervisor to initialize the SEV platform
