Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header. 2020-01-18 05:38:21 -03:00			`/*`

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt * 2021-04-22 05:24:48 -03:00			`* SPDX-License-Identifier: BSD-2-Clause`

Kernel: Implement very simple kernel module loading It's now possible to load a .o file into the kernel via a syscall. The kernel will perform all the necessary ELF relocations, and then call the "module_init" symbol in the loaded module. 2019-11-28 16:59:11 -03:00			`#pragma once`

Kernel: Implement basic module unloading :^) Kernel modules can now be unloaded via a syscall. They get a chance to run some code of course. Before deallocating them, we call their "module_fini" symbol. 2019-11-28 17:07:22 -03:00			`typedef void* (*ModuleInitPtr)();`
