Alexander Shishkin ee368428aa perf/x86/intel/pt: Handle VMX better ... Since commit: 1c5ac21a0e ("perf/x86/intel/pt: Don't die on VMXON") ... PT events depend on re-scheduling to get enabled after a VMX session has taken place. This is, in particular, a problem for CPU context events, which don't normally get re-scheduled, unless there is a reason. This patch changes the VMX handling so that PT event gets re-enabled when VMX root mode exits. Also, notify the user when there's a gap in PT data due to VMX root mode by flagging AUX records as partial. In combination with vmm_exclusive=0 parameter of the kvm_intel driver, this will result in trace gaps only for the duration of the guest's timeslices.
