anna	104578d072	sched: add thread management syscalls	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	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	60ec99692c	serial: "fix" buffer truncation bug ... DMA just uses one buffer rather than two now lmao	3 years ago

anna	f5590becd3	syscall: add sleep system call	3 years ago
anna	83ee9603e7	file: add file kevent and i/o wait 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	8b3a5fd68d	sched: integrate into kent hierarchy ... This is an initial, rudimentary attempt at integrating the scheduler into the kent hierarchy. There are likely gonna be drastic changes in the future, and i haven't even tried running the whole thing. But hey, the code compiles again now!	3 years ago
anna	f0dc3a3433	kiss capitalism goodbye for good ... The CNPL will make sure that absolutely no corporation is going to get anywhere near Ardix -- exactly as it should be. Fuck you, corporations!	3 years ago
anna	6f6be12e83	printk: introduce temporary buffer ... This is just a proof of concept for now, i am perfectly aware of the fact that this will cause buffer overruns if the line gets too long.	3 years ago
anna	dca3e716ca	serial: add zero-copy dma i/o api	3 years ago
anna	ec3b64d232	string: move header to standard location ... Anything that implements POSIX should also be where POSIX defines it to be, otherwise it would be pretty useless lol	3 years ago
anna	af8210da4a	piss off capitalism ... Ardix is being relicensed to GPL v3 or later. I have no idea whether you can just do this if you feel like it or if it has any consequences, but i kinda don't really care that much about it. Any changes made after this commit will definitely fall under the GPL though, and considering that only few things are really working yet anyways this is good enough for me.	3 years ago
anna	4349420217	kent: redesign api ... This also got the dmabuf refcount hard fault issue resolved somehow. Don't ask how or why, i'm just glad it works now.	3 years ago

Felix Kopp	9c1b546b16	user: i can't do this anymore ... Living as a sheep herder on a lonely island is becoming an increasingly appealing option the more i am exposed to my stupidity and inability to memorize the return values of basic libc functions that i even implemented myself two fucking months ago.	3 years ago
