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
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
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
points to aarch64 ld, add aarch64 heap, init, page tables and usermode,
make hhdm_offset a global atomic, aarch64 uses semihosting for output,
add generic PageTable type, add a function that creates and maps pages,
use allow to remove warnings, add a bufwriter so kernel panic always
works
(nothing yet) by stubbing lots of functions and modules, make the frame
allocator and heap multiarch, make kernel panic print inside of serial
on x86_64
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
fix munmap number, remove the draw calls, make address space an option,
copy only the top 256 bytes of the HHDM and map the ELF code inside
userspace, add safe copying from userspace
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
FRAME_ALLOCATOR global, make XunilFrameAllocator not hold Limine entries
so it can be used without lifetimes, implement the process struct, add
user heap by giving back heap_start from ELF and adding sbrk syscall,
align ELF loading in userspace_stub, implement lots of libc functions in
libxunil, remove x86_64 dependency from libxunil, add malloc and all
required heap functions to libxunil and more syscall numbers, add a util
file to libxunil, add build scripts for libxunil and doomgeneric
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
implementation, running support, also basic syscalls to test if it
works. add a syscall ABI and a new libxunil ABI for calling back to the
kernel with syscalls, add user mode protection when running ELF, add TSS
Privilege Stack table to fix GPF issues, add invalid opcode handler, fix
rust panics using rectangle_filled instead of fb clear. Also add a hello
world example binary that runs in usermode at startup.
