Using an embedded debug agent, as opposed to an external JTAG debug probe, requires a connection between the service processor and the JTAG chain of the target CPU.

I spent the past two days at the Open Compute Project (OCP) U.S. Summit 2017, in Santa Clara, California. The HUGE news is that Microsoft has ported Windows Server to ARMv8 chips from Qualcomm and Cavium (but, for now, only for use within Azure).

The use of embedded run-control is fast becoming a standard for remote debug on Intel server designs. It’s important to understand the key functionality and performance criteria in evaluating a solution for this application.

Run-control technology is rapidly becoming a de facto standard for forensics retrieval within high-availability, Intel Xeon-class servers. How did this standard come to be established?

The conventional approach to hardware-assisted debugging on Intel platforms involves physically connecting an external probe to the target. Is there a better way?

In my last blog, I referred to the use of run-control technology to very quickly exercise the PCI Express link training state machine. What other kinds of tests can be run with this approach?

It is often part of a hardware validation test suite to initiate multiple PCIe bus retrains, looking for hardware design issues, or LTSSM RTL bugs in the device under test. These test suites take a very long time to run. Is there a way to speed them up?

One in 10,000 times, your notebook crashes when you wake it up in the middle of a backup of your hard disk. No big deal?

When an x86 system has crashed, gathering forensics data to help diagnose root-cause of the failure is a top priority. But, how is this done if the system has crashed, and OS/BIOS-based application programs cannot access the platform?
