METHOD AND DEVICE FOR ADVANCED CONFIGURATION AND POWER INTERFACE (ACPI) SLEEP STATE SUPPORT USING CPU-ONLY RESET |
摘要 |
<p>A mechanism for firmware to gain control from the operating system of an Advanced Configuration and Power Interface (ACPI)-compliant computing device during sleep-state transitions even if the computing device lacks a dedicated means for such a change to occur is discussed. Embodiments of the present invention report a CPU-only reset register in place of a sleep control register for an ACPI-compliant computing device in which an operating system is attempting a sleep-state transition. A CPU reset value is substituted for a sleep type value in a sleep-state object and written to the CPU-only reset register that was reported instead of the sleep control register thereby triggering a CPU-only reset. Firmware code operating at a known CPU reset vector may perform specified processing and then authorize a transition to the originally requested sleep-state.</p> |
