Abstract: Technologies for secure channel identifier mapping include a computing device having an I/O controller that may connect to one or more I/O devices. The computing device determines a device path to an I/O device that may be used to identify the I/O device. The computing device identifies a firmware method as a function of the device path and invokes the firmware method. In response, the firmware method determines a channel identifier as a function of the device path. The firmware method may determine a pre-determined channel identifier for static or undiscoverable I/O devices. For dynamic I/O devices, the firmware method may determine the channel identifier using a stable algorithm. The I/O controller may assign the channel identifier to the dynamic I/O device using the same stable algorithm. The computing device establishes a secure channel to the I/O device using the channel identifier. Other embodiments are described and claimed.

Abstract: Techniques for secure remote debugging of SoCs are described. The SoC includes an intellectual property (IP) block, a microcontroller, and a fabric coupled to the IP block and the microcontroller. The IP block transmits, via the fabric, information regarding events within the IP block to the microcontroller. The microcontroller executes firmware including a network stack and a remote debugger program. Using the firmware, the microcontroller provides the event information to a device external to the SoC.
