• e1c2373691 Use native syscalls instead of interrupt-based ones, move syscall from driver to arch, and add x86_64 specific native syscalls. csd4ni3l 2026-04-19 22:43:20 +02:00
• 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 csd4ni3l 2026-04-19 18:22:16 +02:00

• 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 2026-04-07 18:06:52 +02:00
• ae3915147a Add a usermode address space which can be switched to, make 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 csd4ni3l 2026-04-05 20:12:59 +02:00
• 1e899e2f97 Add a scheduler which just keeps of processes for now, and a 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. csd4ni3l 2026-04-03 11:28:31 +02:00
• 720b68190d Add doomgeneric submodule csd4ni3l 2026-04-01 21:27:39 +02:00
• 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 csd4ni3l 2026-04-01 21:25:34 +02:00
• 47a480009f Fix sleep not being imported and re-add the boot_animation. csd4ni3l 2026-04-01 14:18:17 +02:00
• 9aeff321f8 Add ET_EXEC ELF loading and validation, and a non-working ET_REL 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. csd4ni3l 2026-04-01 14:06:20 +02:00
• 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 2026-03-30 16:24:42 +02:00
• 91828daae2 Remove old next variable from the frame allocator, add a mouse bitmap for drawing and move mouse drawing and updating functions to the mouse struct. csd4ni3l 2026-03-29 15:59:37 +02:00
• 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 2026-03-29 14:38:43 +02:00
• 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 csd4ni3l 2026-03-28 21:03:13 +01:00
• 4a3c1c9ced Add a linked list allocator for heap that can now do 256 mib due to frame allocator optimizations, make a basic init function in arch that will initialize everything for a given arch. Add tests in kmain for alloc, and add a Locked struct used for static mutables and the linked list. csd4ni3l 2026-03-28 15:06:16 +01:00
• 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 2026-03-24 13:48:31 +01:00
• 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 2026-03-23 18:29:33 +01:00
