BUG: sel4sys: size_bits() returning wrong value for seL4_NotificationObject. * instead of returning seL4_NotificationBits it returned seL4_NotificationBits Change-Id: I9a59e8ce921a033a52ba2ed193c6d267cbfa1419 (cherry picked from commit 609991e1a560f48b1d67dbd61cacec366036facc)
Shodan is a project to build a low-power secure embedded platform for Ambient ML applications. The target platform leverages RISC-V and OpenTitan.
The Shodan software includes a home-grown operating system named CantripOS, that runs on top of seL4 and (ignoring the seL4 kernel) is written almost entirely in Rust. CantripOS is comprised of a set of system services that are assembled using CAmkES and applications that are dynamically loaded into a constrained seL4 thread context and communicate with system services through an SDK runtime environment.
The CAmkES project that assembles the CantripOS system services is found in this git repository. It exists outside the seL4 source trees since it contains code not intended to go to upstream seL4.
The target-platform-dependent CAmkES assembly description is found in apps/system/platforms. It is built using the standard CAmkES build system and requires the CAmkES dependencies already be installed. Top-level configuration is found in easy-settings.cmake and settings.cmake with build-related configuration in build/kata.mk and nearby makefiles.
