csd4ni3l 880c589950 fix aarch64 compile by specifying sysroot, revert no cross-building,
always install cross-build deps
2026-06-01 00:19:14 +02:00
csd4ni3l c2877f9451 Turns out badapple wasn't added to the repo, also update README for
SPECIFIC running instructions
2026-06-01 00:06:57 +02:00
csd4ni3l 43ec0e97df Add a proper VFS in a struct which now lives on the heap with no hacky
static lifetimes, move cursor.bmp to image assets and add wallpapers,
and a logo, add Github Action that auto-releases, add build_all script
which just builds without running

csd4ni3l f943cf5426 Increase kernel heap size to fit more ELFs, improve scheduler by
removing O(n) operations (ready and sleep queues now), caching timer
ticks per irq on init_interrupts aarch64, only saving context when
switching, add kill syscall and use it for exit, only push input to
init, fix accidental REL_X events drop with virtio, fix the possibility
of not having a process to switch to by either staying, switching or
idling, improve scheduler by removing double locking and splitting code
to multiple functions, do not switch every IRQ but only 100 IRQs,
improve rust app building, move x86_64 kernel fb so it doesn't hit heap,
update submodules

csd4ni3l 6b4b53729b Add shell as a submodule, didnt work in previous commit 2026-05-28 18:52:07 +02:00
csd4ni3l 5f4154bd24 Remove unused imports, merge ps2 and virtio to both use linux input
events and move parsing code to libxunil, and add mouse support again by
using them, remove unneeded graphics and console output code, merge
build files to a rust app builder, make framebuffer a driver and remove
the graphics folder, add shell as an app in VFS

csd4ni3l 6ebc6ada09 Increase kernel stack size to 2mb, move from cooperative to timer
preemption based scheduling, add correct save_lock on aarch64, add
simple IPC (read, write, manage), and simple and unsecure SHM, add
per-process kernel stacks, add copy_cstr_to_user, always use run_next
for aarch64, remove primitives from the kernel
2026-05-26 09:53:59 +02:00
csd4ni3l 56c5da0742 Improve aarch64 support by building everything for both archictectures,
remove incorrect timer frequency set, fix interrupt handler not
restoring stack ptr, handle both user and kernel aborts, remove aarch64
ps2 support, fix ELF code mapped as code making it unwritable, add
assets.rs to handle both arches automatically, make PS2 x86_64
compatible with linux keycodes, always try printing kernel panic to
serial
2026-05-22 22:18:42 +02:00
csd4ni3l 1205d8ce7a Add virtio driver for aarch64 with only input for now, move keyboard,
mouse and other io logic to an io folder, make ps2 convert to linux
event codes like virtio, force modern mmio and gic version 2 on aarch64
2026-05-17 20:32:42 +02:00
csd4ni3l 85e0d45d3c Add correct framebuffer mapping, so Doom works again, remove unneded
code, add cooperative scheduling on syscalls determined by the
reschedule flag, make serial console automatically clear and be a single
render, make process_scancodes push to all processes, add a user-facing
framebuffer to be mapped, automatically swap buffers inside timer
interrupt, update all submodules

csd4ni3l 2b8a965c92 Update submodules to latest version 2026-04-10 12:53:40 +02:00
csd4ni3l c81bed2a4e Add correct sleep which works now because interrupts are re-enabled
using sti in syscalls, remove a bunch of old imports and code, move
keyboard scancode handling to keyboard.rs, add a new KeyboardEvent based
layout where press/release and unicode is handled, add a kbd_read
syscall which writes kbd events to a userspace buffer, add a usercopy
file which provides safe copying functions to userspace
2026-04-10 12:48:00 +02:00
csd4ni3l eee088c48f Add better register clobbering to syscall calling in libxunil, add header magic to verify each free/malloc/realloc/calloc statement, add our own memcpy, memcmp, memset, memmove 2026-04-07 22:11:18 +02:00
csd4ni3l 9e8090c736 Make Doom run by improving and fixing libc stubs, adding proper heap
allocation, adding a timer, a framebuffer swap, rectangle and buffer
draw syscall, moving the header files to the correct directory,
disabling stack protection, AVX and MMX, while enabling SSE, fix
interrupt handler popping in the wrong order, improve
load_segment_to_memory alignment, add load_from_ptr to framebuffer for
very quick drawing, serial_print as well as render font in
consolewriter, zero the memory in sbrk, add a fake file system and
methods to libxunil for DOOM, add correct printf, vsnprintf add _start
which calls the main function in libxunil, mark all registers as used
inside syscalls for no memory corruption, add build_helloworld.sh script
2026-04-07 18:06:52 +02:00

csd4ni3l 6ac13a876f Add ET_DYN support for the ELF loader, which required adding
relocations, add some more functions to libxunil, use include inside of
tests instead of manually defining types and add basic libc header
files. Move libxunil to the user folder, and add helloworld and
doomgeneric as apps
