2025-08-25	Add error numbers	Carlos Maiolino
	This is supposed to be compliand with POSIX Signed-off-by: Carlos Maiolino <[email protected]>
2025-08-25	Add math lib	Carlos Maiolino
	So far I just need a roundup routine to implement a basic heap manager Signed-off-by: Carlos Maiolino <[email protected]>
2025-08-25	IO: Add in/out declarations/definitions	Carlos Maiolino
	I've forgotten to commit this when working on interrupts. The OS won't build without these helpers. They are used for now mostly to setup PICs. Signed-off-by: Carlos Maiolino <[email protected]>
2025-08-22	vga.h: Fix unknown type name	Carlos Maiolino
	This has only been working so far because vga.h was included only on source files already including stdint.h. We should put it direct to the header file Signed-off-by: Carlos Maiolino <[email protected]>
2025-08-01	Setup interrupt handling	Carlos Maiolino
	Remap master PIC to IOAddress 0x20 to avoid collisions with CPU exceptions. Setup a default interrupt handler and map all interrupts to this handler by default. Setup a Keyboard interrupt handler for testing purposes Wire everything up in the Makefile Signed-off-by: Carlos Maiolino <[email protected]>
2025-08-01	Implement interrupt descriptor table	Carlos Maiolino
	Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-26	Add memset() to the library	Carlos Maiolino
	Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-26	Move include files to a subdirectory	Carlos Maiolino
	Move the include files to the toxic/ subdirectory, so it gets a bit more organized. Ah, yeah, OS name will be renamed to ToxicOS Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-25	Build vga and string libs	Carlos Maiolino
	Also add a small test to the kernel code Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-25	Add VGA text mode driver	Carlos Maiolino
	Add driver to deal with VGA text mode. Also adds a simple vprintl function while I don't implement a print library. Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-25	Add string libraries	Carlos Maiolino
	Add a couple string lib functions to start with video text development. Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-20	Add kernel.c	Carlos Maiolino
	Create the kernel.c file and its initial start_kernel(), and jump to it from the ASM. Also setup the build system to actually build it Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-20	Force alignment of kerne code.	Carlos Maiolino
	It should be aligned to 16-bits IIRC, forcing the kernel.asm to be alined to a 512 byte boundary should suffice Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Add small ATA driver to load kernel	Carlos Maiolino
	Write ata_lba_read routine to load 100 disk sectors from the disk into memory address 0x00100000 (1MiB). Once the data is loaded, jump to that Address Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Start writing the kernel and add a linker script	Carlos Maiolino
	Move the code unders [BITS 32] label to its own file to be loaded as a kernel by the boot loader. Add a linker script to link the bootloader and the kernel in a single binary file. Add a build script to make it easier to use the cross compiler Update the Makefile to build everything and pack it into the os.bin Signed-off-by: Carlos Maiolino <[email protected]>
2025-07-17	Enable A20 line	Carlos Maiolino
