Any examples of using uefi-rs to load an ELF? #424

Closed AGSaidi closed 2 years ago

https://github.com/rust-osdev/uefi-rs/tree/main/template calls out that since you can't use a customer linker script you probably want to use uefi-rs as a shim to load an ELF kernel. Are there any examples of doing this?

Hello. Yes, you can look at the bootloader crate as an example for this; it does precisely what you need: provides a BIOS/UEFI compatible entry point which then loads and runs an ELF-based kernel image.
