anna	5d2539fc4a	kent: avoid recursion	2 years ago
anna	3e35afcfa9	atom: redesign API	2 years ago
anna	f293c6661e	enable debug features by default if DEBUG is on	2 years ago
anna	4177931774	arch/at91sam3x8e: fix vector_table const decl	2 years ago
anna	e80a6cb630	update placeholder name in comment	2 years ago
anna	ad76275721	fix remaining compiler warnings ... This commit removes all inline annotations that the compiler does not actually inline, and inserts pragma directives to selectively disable warnings where necessary.	2 years ago
anna	adccbef80d	arch/at91sam3x8e: fix compile error ... Enabling CONFIG_CHECK_SYSCALL_SOURCE resulted in a compile error because the corresponding code block used an outdated variable name. This commit fixes the issue.	2 years ago
anna	c767d551d3	initd: implement simple test init daemon	3 years ago
anna	104578d072	sched: add thread management syscalls	3 years ago
anna	a370ef69f6	config: lower default sched freq to 200 Hz ... 1 kHz was way too much (the CPU could barely get anything done in a time window of just 1 ms) and the task can be put to sleep due to system calls anyway, so this should be fine.	3 years ago
anna	2ea850cead	init: use correct mm init function name	3 years ago
anna	fb9ec2a8bc	mm: make malloc and free system calls ... This is required because the heap is shared among all tasks and protected using a mutex which only works in kernel space.	3 years ago
anna	040b5af5d6	malloc: poison heap when DEBUG is defined	3 years ago
anna	8293d9372b	mutex: don't rely on malloc for waitqueue	3 years ago
anna	b7e9187740	main: move kernel start routine to kernel/	3 years ago
anna	75d2fb4470	vscode: fix debug config file location	3 years ago
anna	60ec99692c	serial: "fix" buffer truncation bug ... DMA just uses one buffer rather than two now lmao	3 years ago
anna	d1805c2f00	dma: make memory allocations atomic	3 years ago
anna	10e8b00fb0	sched: avoid memory allocation for kernel task	3 years ago

anna	02ed1b5779	malloc: mask flags for neighbor offset	3 years ago
anna	f85006f224	malloc: remove obsolete assert statements ... A relict of debugging on my host.	3 years ago
anna	8e9678577e	malloc: fix my shit code so it's less shitty ... The allocator works now. At least when i compile it for amd64. I haven't actually flashed it yet tho lmao.	3 years ago
anna	83ee9603e7	file: add file kevent and i/o wait support	3 years ago
anna	364290f192	arch: add files i fucking forgot to commit	3 years ago
anna	59db5471ed	malloc: rewrite with atomic support	3 years ago
anna	7e6dbad05f	sched: complete rework of context switching ... The old strategy was to only do context switching from within the PendSV handler. This worked fine until now because all syscalls were handled either atomically or just returned -EAGAIN if the resource was locked or busy. However, with the introduction of I/O wait, we need to be able to sleep directly from within the kernel by moving the context switching completely into the kernel.	3 years ago
anna	60f1ebea8a	arch: use CMSIS after all ... It was inevitable, tbh. I really wanted to do everything entirely from scratch, but all those hardware registers are just too much to be maintained by a single person. And since i plan on supporting different boards at some point in the future, it would be complete madness to redo everything for that board.	3 years ago
anna	b122e54ec8	handle_fault: fix hex stringification algo	3 years ago
anna	e96ee14e68	sched: make sleeping actually work	3 years ago
anna	b4046795c8	list: fix shit	3 years ago
anna	c24b183c60	init: fix init array pointer dereference bullshit	3 years ago
