Смысл: The text provides a foundational technical overview of the SPI protocol and how the Linux kernel abstracts this hardware interface through a layered driver model to allow for the development of protocol-level drivers.
A technical introduction to the SPI bus protocol and the architectural structure of its implementation in embedded Linux.
Смысл: The main idea is to demystify the operation and configuration of the iSCSI initiator in Linux, moving beyond simple target setup to explain the state-based logic of open-iscsi and its integration into the OS as a block device.
A comprehensive technical guide on setting up and managing the open-iscsi initiator in Linux, covering terminology, lifecycle, and multipathing.
Смысл: The main idea is to explain the evolution and technical functioning of Direct Memory Access (DMA) as a critical optimization over Programmed Input/Output (PIO) to prevent CPU saturation during high-volume data transfers.
A technical guide explaining how DMA allows hardware devices to transfer data directly to memory, bypassing the CPU to improve system performance.
