As of Intel SDM (https://www.intel.com/sdm) version 076, there is a new Intel PT feature called Event Trace which adds a bit to the existing MODE.Exec packet to record the interrupt flag. Previously, the MODE.Exec packet did not generate any events, so the new processing required is practically the same as a new packet. Signed-off-by:

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. Signed-off-by:

Factor out clearing of FUP (Flow Update) event variables, to avoid code duplication. Committer Notes: From the Intel documentation: <quote> Flow Update Packets (FUP): FUPs provide the source IP addresses for asynchronous events (interrupt and exceptions), as well as other cases where the source address cannot be determined from the binary. </quote> Signed-off-by:

® 64 and IA-32 architectures software developer’s manual combined volumes: 1, 2A, 2B, 2C, 2D, 3A, 3B, 3C, 3D, and 4" PDF at: https://cdrdv2.intel.com/v1/dl/getContent/671200 And these new packets are described in page 3951: <quote> 32.2.4 Event Trace is a capability that exposes details about the asynchronous events, when they are generated, and when their corresponding software event handler completes execution. These include: o Interrupts, including NMI and SMI, including the interrupt vector when defined. o Faults, exceptions including the fault vector. — Page faults additionally include the page fault address, when in context. o Event handler returns, including IRET and RSM. o VM exits and VM entries.¹ — VM exits include the values written to the “exit reason” and “exit qualification” VMCS fields. INIT and SIPI events. o TSX aborts, including the abort status returned for the RTM instructions. o Shutdown. Additionally, it provides indication of the status of the Interrupt Flag (IF), to indicate when interrupts are masked. </quote> Signed-off-by: -

Some Intel TMA metrics compute a ratio that may divide by 0, which causes the metric not to print. This happens for metrics with FP_ARITH events. If we see these events in the result and would otherwise fail, then switch to a skip. Also, don't early exit when processing metrics. Reviewed-by:
