Mentorship Session - Unraveling RCU-Usage Mysteries - Fundamentals

Delve into the fundamentals of Read-Copy-Update (RCU) in this comprehensive mentorship session. Explore the two core conceptual components of RCU: the mechanism for publishing and subscribing to pointers, and the method for waiting for pre-existing readers. Learn how to effectively combine these components with other mechanisms to bridge the gap between RCU's core API and recognizable use cases. Discover the process of implementing a reader-writer lock using RCU and understand how it can be utilized for phased state changes. Gain insights into topics such as log scale, hardware latency, global agreement, and lighter-weight semantics. Examine the RCU API, its semantics, and restrictions, while also exploring RC semantics and structure through practical examples. Engage with exercises on space-time synchronization, readers and updaters, and spatial synchronization. Master list primitives and general rules for RCU usage, including cross-reader interlock and exceptions. By the end of this session, acquire a deeper understanding of RCU's conceptual simplicity and its practical applications in various scenarios.
