摘要： Technologies for hybrid sleep power management include a computing device with a processor supporting a low-power idle state. In a pre-boot firmware environment, the computing device reserves a memory block for firmware use and copies platform wake code to a secure memory location, such as system management RAM (SMRAM). At runtime, an operating system may execute with the processor in protected mode. In response to a request to enter a sleep or suspend state, the computing device generates a system management interrupt (SMI). In an SMI handler, the computing device copies the wake code from SMRAM to the reserved memory block. The computing device resumes from the SMI handler to the wake code with the processor in real mode. The wake code enters the low-power idle state and then jumps to a wake vector of the operating system after receiving a wake event. Other embodiments are described and claimed.

摘要： Technologies for selectively enabling platform-specific features includes a computing device that initializes virtual device driver logic to interface with a virtual device of an Advanced Configuration and Power Interface (ACPI) subsystem. The ACPI subsystem includes an operating system (OS)-specific function specification associated with the virtual device. The OS-specific function specification includes OS-specific functions to be performed by the ACPI subsystem based on an identified OS. The virtual device driver logic transmits a call to the OS-specific function specification in the ACPI subsystem. The call includes an identifier of an OS of the computing device that uniquely identifies the OS from other operating systems. The ACPI subsystem analyzes the OS-specific function specification to determine OS-specific functions associated with the OS based on the identifier. The ACPI subsystem performs the determined OS-specific functions.

摘要： Technologies for pre-memory phase initialization include a computing device having a processor with a cache memory. The computing device may determine whether a temporary memory different from the cache memory of the processor is present for temporary memory access prior to initialization of a main memory of the computing device. In response to determining that temporary memory is present, a portion of the basic input/output instructions may be copied from a non-volatile memory of the computing device to the temporary memory for execution prior to initialization of the main memory. The computing device may also initialize a portion of the cache memory of the processor as Cache as RAM for temporary memory access prior to initialization of the main memory in response to determining that temporary memory is not present. After initialization, the main memory may be configured for subsequent memory access. Other embodiments are described and claimed.

摘要： A method, system, and computer program product containing instructions for handling legacy BIOS services for mass storage devices using system management interrupts. In response to receiving a request for an input/output service, a system management interrupt is generated to enter system management mode. A system management RAM (SMRAM) is accessible to code executing inside system management mode. Sub-operations to perform the requested service are identified, and code is executed outside the SMRAM to perform a sub-operation to fulfill the request. The sub-operations identified for execution outside SMRAM include any sub-operations that require waiting for data to be transferred. Other code executing inside the SMRAM may perform additional sub-operations that do not require waiting for data transfers to fulfill the request. System management mode is exited before invoking the code to perform the sub-operation to execute outside the SMRAM.
