RISC-V Summit

Debug infrastructure is a critical element in any system. Debug features within every layer of the software stack provide the needed visibility toward finding issues in any system. Paul Donahue is the vice-chair of the RISC-V Debug Task Group and author of the requirements for debug support that have recently been added to the OS-A platform specification. In this talk he will provide an overview of the debug architecture features that are in OS-A. These features provide a consistent minimum feature set that debuggers (both native and external) can rely on for debugging everything from the first instruction after reset to operating systems and hypervisors to user applications.
