摘要:
A method and apparatus is described herein for managing bad blocks/sectors in a nonvolatile memory. Upon detecting an input/output fault to a target block in a nonvolatile memory, the target block is remapped to a spare block, if the block is predicted as a bad block. Remapping is done for blocks used to store code both in serial execution code sequences and code sequences utilizing address translation. The remapping of bad blocks/sectors in nonvolatile memory allows nonvolatile memory in computer systems to be robust and resilient in handling bad blocks.

A method according to one embodiment may include partitioning a plurality of core processors into a main partition comprising at least one processor core capable of executing a main operating system and an embedded partition comprising at least one different processor core configured to execute an embedded operating system. The method may also include exchanging, by the embedded partition, commands and data with a redundant array of independent disk (RAID) system coupled to the embedded partition; and generating by the embedded partition parity (P) data related to the RAID system.

Methods and apparatus to provide secure firmware storage and service access are disclosed. One example method may include receiving a request to execute an instruction in a pre-boot environment, determining an identity of the instruction, determining if an access control list includes an entry corresponding to the instruction, and selectively allowing the execution of the instruction if the access control list includes an entry corresponding to the instruction.

A method according to one embodiment may include partitioning a plurality of core processors into a main partition comprising at least one processor core capable of executing an operating system and an embedded partition comprising at least one different processor core. The main partition and embedded partition may communicate with each other through a bridge. The embedded partition of this embodiment may be capable of: mapping two or more mass storage systems, coupled to the embedded partition, into a single logical device; presenting the logical device to the bridge; and receiving at least one I/O request, generated by the main partition and directed to the logical device, and in response to the I/O request, the embedded partition may be further capable of communicating with at least one of the two or more mass storage systems using at least one communication protocol to process said I/O request; and reporting the status of the I/O request to the main partition, via the bridge.
摘要:
A system and method to diffuse optimized libraries via a network. An optimized library including at least one optimized routine is received by a processing system via a network. The optimized routine is provided for use by an application executing on the processing system to interact with a hardware entity of the processing system.

The present disclosure relates to a technique or device to allow hardware related drivers to present a centralized configuration program and, more particularly, to a technique or device to allow hardware related drivers to present configuration information to a centralized user interface manager.
摘要:
A method according to one embodiment may include retrieving selected data from one or more mass storage devices, based at least in part on historical device access information of at least one requester of data. A method according to another embodiment may include retrieving, by an integrated circuit, device data layout information from one or more mass storage devices, and storing, by the integrated circuit, the device data layout information in cache memory. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Methods, apparatus, and systems for updating firmware for clustered computing platforms. Firmware provided on each platform is loaded for operating system runtime availability. The firmware update process begins by issuing an update directive that includes firmware update data to a first platform. That platform then interacts with firmware running on other platforms to update the firmware for those platforms, wherein communications between the platforms is enabled via an out-of-band (OOB) communication channel or network. In one embodiment, OOB communications are facilitated by a hidden execution mode known as the System Management Mode (SMM), which has the ability to receive and respond to periodic System Management Interrupts (SMI) and execute corresponding SMI handlers configured to support inter-platform communication in a manner that is transparent to operating systems running on the platforms. The method allows firmware to be updated across multiple platforms, such as server blades, using a single administrative action.
摘要:
A method and system to push capabilities into firmware by an operating system. A pre-boot driver is accessed at a computer system during operating system runtime of the computer system. The pre-boot driver is deposited in a repository available to firmware of the computer system. The pre-boot driver is found at the repository by the firmware during a subsequent pre-boot phase of the computer system. The pre-boot driver is executed during the subsequent pre-boot phase. In one embodiment, the computer system includes firmware that operates in accordance with the Extensible Firmware Interface (EFI) framework standard.
