Currently, the transaction flag (x) is kept separate from branch flags. Instead of doing the same for the interrupt disabled flags (D and t), add all flags so that new flags will not need to be handled separately in the future. Signed-off-by:

It is not possible to walk the executable code without TNT packets, so force 'quick' mode when TNT is disabled, because 'quick' mode does not walk the code. Signed-off-by:

Synthesize an attribute event and sample events for Intel PT Event Trace events represented by CFE and EVD packets. Committer notes: Make 'struct perf_synth_intel_evd evd[]' evd[0] at the end of 'struct perf_synth_intel_evt' as it is breaking the build with in many compilers with (e.g. clang version 13.0.0 (Fedora 13.0.0-3.fc35)): util/intel-pt.c:2213:31: error: field 'cfe' with variable sized type 'struct perf_synth_intel_evt' not at the end of a struct or class is a GNU extension [-Werror,-Wgnu-variable-sized-type-not-at-end] struct perf_synth_intel_evt cfe; ^ Signed-off-by: -

Define 2 new flags to represent: - when interrupts are disabled (D) - when interrupt disabling toggles (t) This gives 4 combinations: no flag, interrupts enabled t interrupts were enabled but become disabled D interrupts are disabled Dt interrupts were disabled but become enabled Committer notes: Those are control flow flags, as per 'tools/perf/Documentation/perf-intel-pt.txt: <quote> An interesting field that is not printed by default is 'flags' which can be displayed as follows: perf script --itrace=ibxwpe -F+flags The flags are "bcrosyiABExgh" which stand for branch, call, return, conditional, system, asynchronous, interrupt, transaction abort, trace begin, trace end, in transaction, VM-entry, and VM-exit respectively. </quote> 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 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: -
