csd4ni3l 17f2a3c7e4 Update template to newest version which fixes edk2, make aarch64 compile
(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
2026-05-14 18:46:17 +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 f4c2657b94 Make keyboard lock-free (and fix Doom deadlock) by only pushing
scancodes to a spsc queue from the interrupts and only process them
inside syscalls. Also make CURRENT_PID atomic to use less locking
2026-04-19 18:22:16 +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

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

csd4ni3l aa5a2a6da6 Make keyboards use events, move all userspace-like code (from mouse as
well) to a stub file instead of being inside the kernel.

csd4ni3l 3ef95940a7 Remove micromath dependency, improve primitive drawing speed by 300x,
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.

csd4ni3l aa5cd85b48 Add a kernel crash function, add a timer using the timer interrupt and
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
2026-03-28 21:03:13 +01:00
csd4ni3l 269d900d97 Add interrupts and IDT and react to double, page, general prot faults
and breakpoints, add keyboard support through the keyboar interrupt, add
paging memory management and a Frame Allocator, add a generic arch
module that initializes arch-specific things, fix framebuffer and
serialconsole being accessed from multiple places, move serial to driver
since its not actually a serial console.

csd4ni3l e28b898d79 Formatted the code, made the arch code x86_64 only for now, fixed the
serial writer always centering and assuming, added a margin for correct
displaying. Added the IDT and GDT tables, and the TSS so double faults
cant happen. Handled all of these interrupts using functions. Serial
console is now topleft and panic messages are formatted correctly from
there. core PI constant is now used instead of our own.

csd4ni3l 7a938283f7 Move to single arch, add serial console, font rendering, panic handling, move graphics to multiple files, use a global mutex framebuffer & serialconsole 2026-03-14 16:40:23 +01:00
