apio	dc389da74e	Implement an ELFImage struct ... This struct allows us to keep track of what memory is used by the loaded executable. For some reason, freeing this memory when the task exits triggers a kernel page fault, so I'm not doing that right now.	2022-10-07 17:54:05 +02:00
apio	1ecd24f5d6	Kernel: Add SSE support (enable SSE on boot and save context (user tasks only) on task switch)	2022-10-02 18:53:54 +02:00
apio	66bee86a8b	Scheduler: add a load_user_task function that directly loads a file from the initrd	2022-10-01 12:28:32 +02:00
apio	f25014a8ed	refine syscalls	2022-09-29 19:17:43 +02:00
apio	f1a7138568	User mode (with a few syscalls) ... IT ACTUALLY WORKS NOW. Why wasn't it working? Oh, because I was not setting already present page tables's permissions to user mode. Just a little bug. THAT I SPENT DAYS TRYING TO FIND Anyways, it works now. Such a relief...	2022-09-25 20:35:05 +02:00
apio	19dff40ee2	Scheduler: track total CPU time of tasks	2022-09-25 17:49:51 +02:00
apio	c3e5251687	Some more userland and font failing	2022-09-23 16:41:43 +02:00
apio	ec01dc2927	Scheduler: Change fixed Task array for (highly inefficient) memory allocation, add userspace task support (which as memory is mapped kernel-only instantly crashes), and support for exiting a task (marking it as exited and reaping it later)	2022-09-21 21:06:00 +02:00
apio	49ddb47ad4	Reorganize structure	2022-09-21 17:56:53 +02:00
apio	1c12cf016e	Add a Scheduler. ... Finally. Just Round Robin with sleeping, but it's still awesome. I think this can finish v0.3, with a few adjustments.	2022-09-20 19:58:04 +02:00
apio	d4a982306f	Add spinlocks	2022-09-18 20:15:19 +02:00
