RH-Commit: [11/91] 21d2178178bf181a8e4d0b051f64bd983f0d0cf1 (bonzini/rhel-qemu-kvm)
|
||
|
|
|
||
|
|
Different confidential VMs in different architectures all have the same
|
||
|
|
needs to do their specific initialization (and maybe resetting) stuffs
|
||
|
|
with KVM. Currently each of them exposes individual *_kvm_init()
|
||
|
|
functions and let machine code or kvm code to call it.
|
||
|
|
|
||
|
|
To facilitate the introduction of confidential guest technology from
|
||
|
|
different x86 vendors, add two virtual functions, kvm_init() and kvm_reset()
|
||
|
|
in ConfidentialGuestSupportClass, and expose two helpers functions for
|
||
|
|
invodking them.
