This series is posted in context of the discussion at:
https://lore.kernel.org/lkml/Ywa9T+jKUpaHLu%2Fl@google.com/
Major changes:
1) Move common startup logic to a single common main function in
kvm_util.c
2) Introduce following APIs:
kvm_arch_main: to perform arch specific common startup.
kvm_post_vm_load: to update the guest memory state to convey
common information to guests.
3) For x86, capture cpu type at startup and pass on the cpu type to
guest after guest elf is loaded.
4) Execute hypercall instruction from within guest VMs according to the
cpu type. This will help prevent an extra kvm exit during hypercall
execution.
Vishal Annapurve (5):
selftests: kvm: move common startup logic to kvm_util.c
selftests: kvm: Introduce kvm_arch_main and helpers
selftests: kvm: x86: Execute vmcall/vmmcall according to CPU type
selftests: kvm: delete svm_vmcall_test
selftests: kvm: Execute vmcall/vmmcall as per cpu type
