Identifying and Supporting X-Compatible Hardware Blocks in SoCs

Explore the process of identifying and supporting 'X-compatible' hardware blocks in SoCs through this informative conference talk by Chen-Yu Tsai from CloudMosa, Inc. Delve into the challenges of working with undocumented IP blocks from various vendors and learn techniques for integrating support for these components into existing Linux kernel drivers. Discover methods for spotting compatible hardware ranging from simple UARTs to complex register-obfuscated HDMI and Ethernet controllers. Gain insights from real-world examples of mainline support for Allwinner SoCs, and understand the importance of community resources, reference manuals, and experience in porting and maintaining kernel support for various hardware components.
