Abstract: Utilities (e.g., systems, methods, etc.) that make use of a secure input/output (I/O) channel between system firmware (e.g., BIOS) and the SP to allow the BIOS to securely send data (e.g., error data) for secure consumption by the SP while preventing or limiting other sources from sending falsified data or the like the SP. The secure I/O channel includes interface hardware (e.g., Field-programmable gate array (FPGA)) that is configured to be unlocked by the BIOS using a security key received from a key generator over a separate security channel. After such data is securely sent to the interface hardware, the BIOS may then pass error interrupt(s) to the OS for performing of any necessary recovery actions. At any appropriate time, the SP may read or consume error data from the memory register of the interface hardware and perform any appropriate diagnoses and/or handling of the error data.
