As of Intel SDM (https://www.intel.com/sdm) version 076, there is a new Intel PT feature called Event Trace which requires 2 new packets CFE (Control Flow Event) and EVD (Event Data). Each Event Trace event is represented by a CFE packet that is preceded by zero or more EVD packets. It may be bound to a following FUP (Flow Update) packet that provides the IP. Event Trace exposes details about asynchronous events. The CFE packet contains a type field to identify one of the following: 1 INTR interrupt, fault, exception, NMI 2 IRET interrupt return 3 SMI system management interrupt 4 RSM resume from system management mode 5 SIPI startup interprocessor interrupt 6 INIT INIT signal 7 VMENTRY VM-Entry 8 VMEXIT VM-Entry 9 VMEXIT_INTR VM-Exit due to interrupt 10 SHUTDOWN Shutdown For more details, refer to the Intel SDM, Intel Processor Trace chapter. Add processing to the decoder for the new packets.
