System platform supporting infrared receiver/transmitter and operation method thereof
First Claim
1. An operation method of a system platform, comprising:
- receiving, by an infrared receiver, an infrared signal from a consumer infrared (CIR) device, the infrared signal containing encoded event data;
transmitting, by the infrared receiver, the infrared signal to a transmission interface;
generating, by the transmission interface, an interrupt notification signal in response to the received infrared signal;
transmitting, by the transmission interface, the interrupt notification signal to an operation system power management agent (OSPM) via an advanced configuration and power interface (ACPI);
transmitting, by the transmission interface, the infrared signal to a universal extensible firmware interface (UEFI) basic input output system (BIOS);
executing an infrared application program running under an operating system stage in response to the interrupt notification signal received from the transmission interface to generate a system management interrupt (SMI) in the UEFI BIOS to execute a system management mode (SMM) program, causing the system platform to enter a BIOS stage from the operating system stage; and
executing, by the UEFI BIOS in the BIOS stage, a decoding driver program, to decode the infrared signal into event data, and store the event data in a storage device.

Abstract
An operation method of a system platform includes steps of: transmitting, by an infrared receiver, a received infrared signal to a transmission interface; transmitting, by the transmission interface, an interrupt notification signal to an operation system power management agent (OSPM) through an advanced configuration and power interface (ACPI); receiving, by an infrared application program of an operating system, the interrupt notification signal from the OSPM, so as to generate a system management interrupt (SMI) in a universal extensible firmware interface (UEFI) basic input output system (BIOS) to execute a system management mode (SMM) program; and executing, by the UEFI BIOS, a decoding driver program, and receiving the infrared signal from the transmission interface, so as to decode the infrared signal into event data, and store the event data in a storage device.
