A system for source language module interaction using an event mechanism includes one or more subsystems to detect a producer event, detect a consumer event, generate a new source language method for the producer event and a new source language method for the consumer event, and link the producer event and the consumer event using the new source language method. In an embodiment, the source language may be ASL.

Modular ASL component

In a Uniform Extensible Firmware Interface (UEFI) environment, a system management mode (SMM) driver and a non-SMM driver may be installed for the same hardware device. Until the SMM driver is available, the non-SMM driver is configured to conduct input/output (IO) transactions directly with the hardware device. The non-SMM driver can utilize native UEFI services to receive a notification that the SMM driver is available. Upon receiving such notification, (or if the SMM driver was already available before the non-SMM driver), the non-SMM driver is reconfigured to redirect all IO requests to the SMM driver, which then conducts the corresponding IO transactions directly with the hardware device. Redirecting all non-SMM IO requests for a hardware device to the SMM driver for the hardware device limits direct access to the hardware device to only one driver, the SMM driver, thereby facilitating the integrity or atomicity of IO transactions.

Input/output transaction management during platform initiation

Information handling system security is simplified and enhanced with user passwords configurable to restrict access to the overall system and separately to the hard disk drive. An administrative password overrides the BIOS password to allow administrative access to the information handling system. Upon creation of a hard disk drive password on a system having an administrative password, the hard disk drive password is saved to the hard disk drive and to the BIOS with access from the BIOS restricted by the administrative password. Upon entry of the administrative password at the BIOS, the hard disk drive password is automatically provided from the BIOS to the hard disk drive to allow access to the hard disk drive.

A mechanism via which system state changes can be detected and corrected automatically prior to a customer initiated boot. The mechanism is extensible to address newly added or discovered system state changes that result in a locked condition. The mechanism detects and corrects adverse events before booting into the operating system.

Handling interrupts within an information handling system including entering into an interrupt management mode in response to receiving an interrupt, identifying at least one source of the received interrupt in accordance with an ordered list of a plurality of possible interrupt sources, dispatching an appropriate interrupt handler to resolve the identified at least one source of the received interrupt, noting a frequency of occurrence of each indentified at least one source generating a received interrupt over time, and recording the ordered list of possible interrupt sources in response to the noted frequency, wherein the possible interrupt sources with higher frequencies are placed in the beginning of the ordered list.
