[PATCH v1 0/4] Enable LBR for the guest
This patch series enables the Last Branch Recording feature for the
guest. Instead of trapping each LBR stack MSR access, the MSRs are
passthroughed to the guest. Those MSRs are switched (i.e. load and
saved) on VMExit and VMEntry.
Test:
Try "perf record -b ./test_program" on guest.
