This patch series aims to make the msr intercept handling, performed in
vpmu code, virtualization technology agnostic.
It creates a common interface for setting/clearing the msr intercepts and
then add hooks to the corresponding hvm_funcs table to be able to call the
svm/vmx specific handlers through a generic hvm wrapper function.
Version 2 addresses the comments made on version 1 to ease further review.
Still there is a pending question made by Jan, whether there could be other,
than the vpmu one, use cases that would require msr intercept handling to be
performed outside of virtualization techonology-specific code, and whether
this abstraction is actually usefull to have.
Xenia Ragiadakou (3):
x86/svm: split svm_intercept_msr() into
svm_{set,clear}_msr_intercept()
x86/vmx: replace enum vmx_msr_intercept_type with the msr access flags
x86/hvm: create hvm_funcs for {svm,vmx}_{set,clear}_msr_intercept()
