Here's a list of bounties I plan on adjusting and then submitting.

First EMU68 Bounty. (This one is set in stone as it was written with the help of mschulz).

Porting Emu68 to EFI
Overview
This bounty focuses solely on adapting Emu68 to function as an EFI binary executable, laying the foundation for future work to enable AmigaOS/AROS 68K to boot natively on ARM hardware. Since EFI handles hardware abstraction via its protocols, the scope of this bounty is limited to making Emu68 compliant with the EFI standard and ensuring basic ACPI table parsing for future use.

Objectives
1. Adapt Emu68 to function as a compliant EFI binary executable.
2. Implement basic support for:
ACPI Table Parsing: Convert Little Endian ACPI data to Big Endian for compatibility with 68K environments.
3. Lay the groundwork for AmigaOS and AROS integration in subsequent phases.

This isn't AROS specific but rather AmigaOS but I didn't want to separate it from the rest.


AmigaOS Boot Implementation for EFI-Based "MC68K" Machine

Overview:

This bounty focuses on the development of a secondary 68K bootloader to enable AmigaOS 68K to boot on an EFI-based "MC68K" machine. The bootloader will be designed to initialize hardware via EFI, emulate missing hardware components like CIA chips and display, and then transition control to the AmigaOS kernel. The bootloader will utilize the Emu68 platform to provide hardware abstraction and initialization.

Key Objectives:

ACPI Table Handling:

Parse and utilize Big Endian ACPI tables (converted in Bounty 1) to extract hardware information such as USB, PCI, networking, and storage.
Provide hardware details to the AmigaOS environment through accessible memory structures or standard tables.
Ensure efficient integration with EFI protocols for seamless hardware initialization.
Development of a Secondary Boot Program:

Create a standalone 68K bootloader program that:
Loads the AmigaOS ROM from an EFI-compliant storage device using EFI_BLOCK_IO_PROTOCOL and EFI_SIMPLE_FILE_SYSTEM_PROTOCOL via Emu68.
Initializes basic system state, including memory mapping, hardware detection, and CIA chip emulation.
Uses EFI-provided input protocols (keyboard/mouse) for interaction during boot, if required.
Transitions control to the loaded AmigaOS kernel.
ROM Loading and Initialization:

Implement a ROM loading mechanism to:
Locate and load the AmigaOS ROM file from storage.
Set up a compatible memory environment for AmigaOS execution.
Use EFI-provided framebuffer graphics (via GOP) to display basic output during boot.
Initialize key hardware interfaces such as storage, input, and display for AmigaOS compatibility.
Emulation of Missing Hardware:

CIA Chip Emulation:

Emulate the missing CIA chips within the bootloader. The CIA chips are responsible for essential hardware interactions like keyboard input, timers, and other system-level I/O tasks. This emulation must mimic the behavior of the original CIA chips to ensure compatibility with AmigaOS.
Display Support:

Emulate display support for AmigaOS, either by:
Using the GOP framebuffer for basic display output.
Optionally simulating Amiga-native graphics modes (PAL/NTSC) by:
Emulating graphics.library functionality in the bootloader to present the framebuffer as a native mode.
Creating a minimal P96 GOP driver for direct rendering.
AmigaOS Transition:

Finalize hardware initialization and transfer control to the AmigaOS kernel, ensuring that:
The kernel has access to hardware details provided by EFI protocols.
A pre-initialized environment for storage, input, and graphics is set up.
Document the handoff mechanism for compatibility with AmigaOS expectations.
Compatibility Testing:

Test the bootloader and overall environment using real Amiga applications, particularly Deluxe Music 2.0, to verify hardware compatibility and proper operation.
Identify and resolve any issues related to hardware initialization or emulation (e.g., CIA chip behavior, input handling, display modes).

Deliverables:

68K Bootloader Program:

A secondary bootloader program running under Emu68 capable of:
Loading and initializing the AmigaOS ROM.
Performing essential hardware initialization, including CIA chip emulation and display emulation.
Transitioning control to the AmigaOS kernel.
Graphics Output:

GOP-based framebuffer graphics support during boot.
Optional support for simulated Amiga-native modes via graphics.library emulation or a P96 GOP driver.
Hardware Abstraction:

Initialization of storage, input, and graphics hardware using EFI protocols.
Accessible tables or structures for AmigaOS to use initialized hardware.
Emulation of CIA Chips and Display:

Emulation of CIA chip functionality in the bootloader.
Display emulation through GOP framebuffer or simulated Amiga-native modes.
Testing and Compatibility:

Verification of the bootloader functionality using Deluxe Music 2.0 and other critical Amiga applications to ensure compatibility and correct operation.
Resolution of any issues identified during testing.
Documentation:

Detailed documentation covering:
Bootloader functionality and setup.
ROM loading and hardware initialization processes.
Mechanism for CIA chip emulation and display emulation.
Transitioning control to the AmigaOS kernel.
Compatibility considerations and testing procedures.

Aros 68k or AmigaOS running on ARM-Hardware with only emu68 as layer would give unbeatable cheap and powerful hardware. Nice new toys

@OlafS25

Would be really something else! A second renaissance

I have this.

but I'm looking into upgrading to this.

The DraCo method requires CIA chips and extra ROM to patch KickStart 3.1 ROM.

UEFI Emu68 would need to patch KickStart 3.x ROM for missing CIA and display.

I use Deluxe Music 2.0 as one of the test apps against the so-called Amiga wannabes.

@Hammer

EMU68 isn't going to be expanded for that purpose. That's the purpose of a secondary bootloader. I will however adjust the AmigaOS bounty accordingly. AROS however has no need for CIA emulation or to patch the Kickstart ROM. That's the point of separating the bounties as much as possible.

Love the list.

Are you planning to run the AROS bounties sequentially or in parallel?
