Hi,
I am looking for the recommended approach for accessing KVM driver data from other kernel components. In my case, I need to set some global variable/state in KVM driver from one of the NMI handlers. I see that using kvm_x86_ops is one option. I can define a new function as part of kvm_x86_ops and invoke that function from the NMI handler as below.
nmi_handler() {
...
If (kvm_x86_ops) {
kvm_x86_ops->new_fn();
}
after adding new_func() to struct kvm_x86_ops.
Is this the right approach ? Or is there some other existing mechanism ? Is KVM driver always loaded ?
I am fairly new to KVM and so any guidance is very much appreciated.
Thanks
Vijay
