Various systems and methods for error handling are described herein. A system for error reporting and handling includes a common error handler that handles errors for a plurality of hardware devices, where the common error handler is operable with other parallel error reporting and handling mechanisms. The common error handler may be used to receive an error message from a hardware device, the error message related to an error; identify a source of the error message; identify a class of the error; identify an error definition of the error; determine whether the error requires a diagnostics operation as part of the error handling; initiate the diagnostics operation when the error requires the diagnostics operation; and clear the error at the hardware device.

Error reporting and handling using a common error handler

The present disclosure provides techniques for translating input camera commands to device-specific commands. Camera commands may be translated by a translation engine located separately from the camera and then transferred to the camera. The translated commands may be less complex than input commands. By translating the commands, older cameras may be capable of supporting newer commands which are not natively supported.

The present disclosure provides techniques for enabling a metadata storage subsystem. A directory of available metadata is created, and the metadata is stored in various system data stores. The metadata is retrieved as requested by a host device, and the metadata is transferred to the host device. Additionally, the metadata is executed.

Enabling a metadata storage subsystem

The present disclosure provides techniques for executing a command within a transport mechanism based on a get and set architecture. An attribute identification of the command is extracted and a get protocol data unit (PDU) is sent from a host device to a imaging device based on the attribute identification in order to obtain attribute values from an image source within the imaging device. Additionally, a response PDU is sent from the imaging device to the host device to complete the execution of the command.

Executing a command within a transport mechanism based on a get and set architecture

A method and system to facilitate paging of one or more segments of a logical-to-physical (LTP) address mapping structure, such as a table, to a non-volatile memory, such as a NAND flash memory. The LTP address mapping structure is part of an indirection system map associated with the non-volatile memory. By allowing one or more segments of the LTP address mapping structure to be paged to the non-volatile memory, the amount of volatile memory required to store the LTP address mapping structure is reduced while maintaining the benefits of the LTP address mapping structure. One or more segments of the logical to physical address mapping structure may be cached in volatile memory, and a size of each segment may be the same as or a multiple of a page size of the NAND flash memory. A lookup or segment table may be provided to indicate a location of each segment and may be optimized for sequential physical addresses.

Methods, apparatuses, and computer program products that enable banded indirection for nonvolatile memory devices, such as flash memory devices, are disclosed. One or more embodiments comprise a method for performing banded indirection when accessing data of a nonvolatile device. The methods comprise tracking fragmentation of a band of physical addresses of the nonvolatile memory device, storing a physical address of the band, and accessing data of a logical address of the band via the stored physical address based on the fragmentation of the band. Some embodiments comprise apparatuses for accessing data of nonvolatile devices using banded indirection. The embodiments comprise a nonvolatile memory element to store data, wherein the nonvolatile memory element has bands of physical addresses, a fragmentation detector to detect fragmentation of a band of the nonvolatile memory, and a data access module to access data of the band via a physical address based on the fragmentation.

Banded indirection for nonvolatile memory devices

A new audio playback architecture may be used, which allows the use of much larger buffering than that used by a typical audio subsystem in a computing system to improve power efficiency of the system and at the same time allows to maintain the quality (e.g., fidelity and responsiveness) of the audio playback. The audio controller in the new architecture may be made to report back to the host system a more accurate indication of which audio frame is being set to the audio codec than a currently available audio controller does. Additionally, the controller is capable of re-fetching previously buffered (but not yet transmitted) data. Furthermore, buffers in both the audio controller and the main memory may be dynamically adjusted during playback of audio data and/or for different applications.

Method and apparatus for maintaining synchronization of audio in a computing system

Machine-readable media, methods, and apparatus are described to recover from stream under-run and/or over-run conditions. In some embodiments, an audio controller may discard any partial sample block of the stream.

Stream under-run/over-run recovery

Provided are a method, system and program for effecting an operating system mode change from one mode to another. In one embodiment, the operating system in one mode is placed in a sleep state in which volatile memory remains active. In booting an operating system from the sleep state, a flag may be detected indicating an operating system mode transfer request. In response, contents of a selected range of volatile memory allocated to the first operating system mode may be swapped with the contents of a selected range of a reserve portion of volatile memory allocated to the second operating system mode. Booting of an operating system in the second mode may be completed using the swapped contents of the volatile memory. Additional embodiments are described and claimed.

Operating system mode transfer

Machine-readable media, methods, and apparatus are described to stream data between a codec and a buffer in system memory and to maintain a value in system memory that is indicative of a current position in the buffer. In some embodiments, an audio controller streams the data across an isochronous channel having relaxed ordering rules to the buffer in the system memory and updates the value indicative of current position via a write across the isochronous channel to the system memory.
