About

The domain context component in OpenSBI provides basic CPU context management routines for existing OpenSBI domain. The context component was initially designed to facilitate the suspension and resumption of domains, enabling secure domains to efficiently share CPU resources, and allowing the UEFI Secure Variable or TEE service to run within it.

Project Scope and Timelines

The reference architecture shown below illustrates the scenario of employing enhanced secure domains to support runtime services, with the opensbi context providing synchronous context switching when a service is called.

Context switch support for standalonemm
Context switch support for TEE (like OP-TEE)

Components and Repos.

Based on OpenSBI v1.4
