Coreforge / aarch64_trap.patch
Created November 20, 2023 17:01
a very quick and dirty adaptation of the arm32 alignment trap to fix one stp instruction for aarch64 code, for the rpi5. Rather printk-heavy

Coreforge / memcpy_unaligned.c
Last active April 20, 2023 18:41
A simple (and not optimal) library to fulfill memory access requirements for BCM2711 PCIe
#include <stddef.h>
#include <stdio.h>
#include <stdint.h>
//#include <stdlib.h>
void* memcpy(void* dst, const void* src, size_t n){
volatile char* vc_src = (char*)src;
volatile char* vc_dst = (char*)dst;
// copy byte by byte, hopefully avoiding any alignment issues
size_t pos = 0;

Coreforge / fbdev.patch
Created March 3, 2021 23:29
patches for linux kernel to get a radeon gpu somewhat working on a raspberry pi
From 5f0a783bb2a819e53dea669128fc3508b4296210 Mon Sep 17 00:00:00 2001
From: Coreforge <BC549b@gmail.com>
Date: Thu, 4 Mar 2021 00:05:51 +0100
Subject: [PATCH 2/2] changes to fbdev to remove 64bit accesses (not replaced
properly yet, just temporary to get it to work. Should only cause every other
pixel to be missing though, not only every fourth one being present)
