You can take a look at [video I implemented some code here: https://github.com/48d90782/angry\_os. At the moment working on EFI and ACPI docs.

Brandon Falk live-codes the beginning of an operating system in Rust, setting up UEFI, ACPI parsing, and QEMU booting.
In this video we start the basics of the OS. Mainly, we dig into ACPI so we can start finding out about memory and APICs. - Stream Starting - Architecture: Using UEFI as Loader - Architecture: Loading Kernel and Memory - Architecture: Kernel Build Process - The Early Stages of Booting - Plan for this Stream - Summary of Boot Process - Rust Setup: cargo, efi_main() and panic handler - QEMU setup and first boot - Start Coding - Core Functions: memcpy, ... - Review of Core Functions: memmove - Pulling in EFI - Running into First Bug - Unregister/Exit EFI Boot Services - Copy Serial Driver from chocolate_milk - Getting ACPI Table - Parsing ACPI Structures - "Bad Code Quality" Refactor - Opinion: Future of Huge RAM Computers (SSD as RAM) - Back to Coding ACPI Table Reading - IF YOU DON'T SUB GET THE F' OUT! - Best Kernel Code Quality - Continue Reading XSDT Entries - Reading MADT (Multiple APIC Description Table) - Thinking About the Implemented Rountine - Back to Coding... APIC - RISCV ACPI Support Research - Looking into ARM Servers - OutroWhy it's here

The best resource, regarding UEFI, I can think of is that video of a live coding stream on twitch : [video
You can find interesting information on how to target UEFI (which apparently is just a PE file with a special entry point and fewer sections) from scratch with Rust and a lot more.
