Hi Paolo and Gleb,
2. CURRENT DESIGN
The design is similar to existing vPMU support. Many data structures such as
struct kvm_pmc and struct kvm_pmu are re-used for this design.
Original pmu.c code was designed with Intel PMU in mind. To avoid the
(if-else forest is daunting.)
I think this approach is quite acceptable, except that there will be many
if-else in the code. Not clean enough.
(b) Convert intel-pmu.c = vmx.c and convert amd-pmu.c = svm.c
* PMU function pointers will be created in kvm_x86_ops;
* The entry functions will be
Hi Paolo and Gleb,

Currently I am working on a formal patch set; but realized that there
are some design choice to make (see below). I thought it is better to
