PCI Protocol and Device Driver Development. (P018)
Abstract
Peripheral Component Interconnect(PCI)
The Peripheral Component Interconnect (PCI) and its modern serial successor, PCI Express (PCIe), are essential standards for connecting high-speed peripherals like graphics cards, storage, and network adapters to a host system. Moving beyond the legacy shared parallel bus, PCIe utilizes a scalable, layered, point-to-point architecture based on differential signaling lanes. The protocol governs crucial system interactions, defining the Configuration Space for device discovery and resource allocation (BARs), Memory-Mapped I/O (MMIO) for register access, and efficient interrupt mechanisms (MSI/MSI-X). Mastery of the PCIe layers is critical for developing robust Linux device drivers that enable the operating system to utilize the device's high-bandwidth capabilities.
Welcome to the Linux PCI Protocol and Device Driver Development Course!
Peripheral Component Interconnect Express (PCIe) is the high-speed backbone of modern computing, facilitating essential communication between the CPU and all critical peripherals, from graphics cards to network adapters. This intensive, 20-hour live online course is designed for kernel enthusiasts and experienced C programmers ready to master this vital interface.
We will systematically dismantle the PCIe protocol's layered architecture, moving from theoretical concepts to practical kernel implementation. By the end of this training, you will have developed a complete, end-to-end Linux PCI device driver, covering crucial low-level tasks such as device discovery, handling interrupts (MSI/MSI-X), and optimizing data transfer using Direct Memory Access (DMA). Prepare to unlock the full performance of hardware within the Linux ecosystem.
