[GSoC 2022] ARM port and device tree support Phase 1

Hello everyone.

It’s been a rough month, I’m having issues with the ARM port and it’s holding me back.

Anyway, I’m on my way, which is great news.

TODO

1. Continue the ARM port

   The latest issue is a page fault occur at thread 778(which is the user thread).

   778:  init: libz.so.1
   vm_page_fault: vm_soft_fault returned error 'Bad address' on fault at 0x0, ip 0x0, write 0, user 1, exec 1, thread 0x30a
   thread_hit_serious_debug_event(): Failed to install debugger: thread: 778 (launch_daemon): Bad port ID
   

2. Prepare fdt

[GSoC 2022] ARM port and device tree support Phase 1

In the first stage of work, the following content was completed:

1. Compile and run arm haiku on osx
2. Fixed some runtime errors

The following will show how to compile haiku on osx and run it on qemu (my version: hrev56168)

Build and run Haiku on OSX (Intel)

Preparation

Before starting, since the default file system(APFS) is not case-sensitive, you must first create a case-sensitive volume.

1. Open Disk Utility.app and press partition

[GSoC 2022] ARM port and device tree support

Introduction

I am Zhihong Niu, an Computer science undergraduate student at the Xi’an Shiyou University.

This summer I will port Haiku to ARM and support some device tree-based storage device.

My mentors for this project are scottmc and David Karoly.

Here is the link to my proposal.

Project

The project actually has three goals: run Haiku on ARM(qemu-system-arm), device tree support and mass storage device driver based on device tree.
