BLOCK DEVICE MANAGEMENT

摘要

Embodiments of the present invention perform a method for reading data from, writing data to, powering on, or configuring a block device without the kernel translating a file system operation into a block device operation. This is implemented by a using a core module to couple applications running in user space to a character device through a character device driver, the core module configures the character device to communicate with a block device through a block device driver without the kernel translating a file system command into a block device command.

主权项

1. A non-transitory computer readable storage medium having embodied thereon a program executable by a processor to perform a method for coupling applications running in user space with hardware block devices, the method comprising:
receiving an outside request by a core module; configuring a character device by the core module to be in communication with a character device driver and a block device to be in communication with a block device driver in an operating system device tree; associating an application with the character device; and associating the character device with the block device such that the application communicates with the block device through an association made by the core module.
