Architectural Event Trace (AET) is a technology on modern Intel silicon that enables processors to provide real-time event trace information. AET differs from code execution trace, which is concerned with the path a processor takes through code; AET traces interactions between individual processors in a system and other processors, the BIOS, OS, device drivers, and external peripherals. Events such as hardware interrupts, exceptions, MSR reads/writes and many others can easily be traced with modern debuggers. And especially when used in conjunction with code execution trace, AET provides additional insight into the root causes of hardware, firmware and software issues.
This webinar will provide advanced examples on the utility of AET and other debug and trace logic on Intel platforms.
