In this installment of the Coding to the SED API series, we’ll look at the SED functions that access the OOBMSM, and use it for super-fast retrieval of hardware telemetry data.
For each of the months of January, February and March, I did a webinar on JTAG-based debugging. Since each of the video recordings are about 45 minutes long, I thought it would be helpful to point out the highlights of each, if you don’t have time to sit through the full durations. At the risk of sounding immodest, there are some real gems of information within the demos of each webinar.
Beginning with Microsoft Azure's Project Olympus, and now a standard within the Open Compute Project, many datacenter servers are now optionally equipped with hardware connectivity between the platform BMC and CPU scan chain. The BMC can thus act as an autonomous JTAG-based embedded out-of-band debug agent, provide low-level triage of system events, such as crashes and hangs. Other use cases, such as hardware validation, manufacturing test, and forensics telemetry are also enabled by this technology.
Don't miss it! ASSET's Alan Sguigna (that's me), in collaboration with the UEFI Forum, will be presenting and demonstrating SourcePoint using the Intel Architectural Event Trace (AET) feature, which offers an unparalleled level of insight into x86 event generation and code execution.
Wow! It has been a while. I wrote Episode 2 of my open-source explorations into the AAEON Intel Apollo Lake-based Up Squared board back on June 7th. In that episode, I gave directions on how to build the UEFI debug image for the board, complete with source/symbols for consumption by JTAG debuggers like SourcePoint. In this episode, I show source-level debug with SourcePoint, and take advantage of Intel Processor Trace on the board.
