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
build_and_run script, fix build.rs sometimes using the wrong
architecture, add badapple ELF and change default font size to 1 for it
to work, improve framebuffer errors, remove unnecessary commands from
make and improve debug filtering
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
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
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
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
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.
