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
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
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
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
interrupts with IRQ and syscalls, make phys_to_virt checked, recreate
stack on aarch64, make serial console finally line wrap and have max
height correctly, add U64Buf for when i need number debug, rename mouse
and keyboard files to kmi and merge them, add non-working pl050 support
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
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
with_process to interact with them. User space now has it's own address
space and mapper which means we will be able to allocate memory for it.
I added a bunch of functions as stubs into libxunil which are required
for 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.
add mouse support and interrupts on x86_64 using a ps2 mouse which
needed pic unmasking, add span filling to framebuffer, add back
without_interrupts to serial console and framebuffer, add a mouse
rectangle which tracks the mouse position and test the performance of
the drawing.
set PIT interval to 1000hz, use a vector inside Framebuffer, remove
without_interrupts from the framebuffer and serial console, move to
usize on primitives, add date at boot and turn on multithreading, add a
boot animation and add a test_performance function with the new timer
