Andreas Kling	239c0bd6a6	Kernel: Make block() and yield() automatically call Scheduler::yield(). ... This exposed some places we were accidentally doing a double yield().	2019-03-24 01:52:10 +01:00
Andreas Kling	fa7f532c35	Kernel: Add a Thread::all_threads() helper.	2019-03-23 23:50:49 +01:00
Andreas Kling	e561ab1b0b	Kernel+LibC: Add a simple create_thread() syscall. ... It takes two parameters, a function pointer for the entry function, and a void* argument to be passed to that function on the new thread.	2019-03-23 22:59:08 +01:00
Andreas Kling	8501fdc6f5	Kernel: Don't add the colonel process' main thread to g_threads. ... This was causing the colonel to get scheduled when he wasn't needed.	2019-03-23 22:17:38 +01:00
Andreas Kling	60d25f0f4a	Kernel: Introduce threads, and refactor everything in support of it. ... The scheduler now operates on threads, rather than on processes. Each process has a main thread, and can have any number of additional threads. The process exits when the main thread exits. This patch doesn't actually spawn any additional threads, it merely does all the plumbing needed to make it possible. :^)	2019-03-23 22:03:17 +01:00
