| Linkable Loadable Extensions (LLEXT) |
| #################################### |
| |
| The LLEXT subsystem provides a toolbox for extending the functionality of an |
| application at runtime with linkable loadable code. |
| |
| Extensions are precompiled executables in ELF format that can be verified, |
| loaded, and linked with the main Zephyr binary. Extensions can be manipulated |
| and introspected to some degree, as well as unloaded when no longer needed. |

| The LLEXT subsystem requires architecture-specific support. It is currently |
| available only on RISC-V, ARM, ARM64, ARC (experimental) and Xtensa cores. |
