kmi - ACTIVE - Kernel with migrating threads as IPC

Age	Commit message (Collapse)	Author
2022-11-13	write init more sensibly	Kimplul
	+ Both easier to look at and now the userspace doesn't play as big of a role in the 'benchmarking' with optimizations turned on.
2022-11-09	add basic IPI structure	Kimplul

2022-10-22	create impl and CAP_PROC checking	Kimplul

2022-10-22	initial high level fork imp	Kimplul

2022-10-21	beautification	Kimplul

2022-10-14	add spawn syscall	Kimplul
	+ Prefer over unixy fork/exec for speed since I don't want to support cow. Shell redirection should be done with env server and cooperating libc.
2022-09-23	remove user data from sys_ipc_notify	Kimplul
	+ Multiple notify signals at the same time, or queued ones waiting for ipc_req/fwd to finish would require a notify stack of some kind, which is maybe too complex for my liking. Not impossible by any means, but I want to keep things simple. Let's say a client wants the server to do some async operation. First, the client calls ipc_req to inform the server that it would like the operation to be done. The server sets this task in some work queue or whatever, and returns to the client as quickly as possible. Later on, when the task is finished, the server does a ipc_req to the client, with data about what was just finished. The client is responsible for noting this data down somewhere, either reacting to the operation directly in the callback, or calling ipc_notify to the thread that requested the operation. Other possible notifications at the same time should be handled at the same time, whichever way the client wants to handle them. Note that ipc_notify triggers only when the thread it targets is in its base state, i.e. not doing an ipc_req. This makes things a bit easier.
2022-09-22	add assign syscall skeleton	Kimplul

2022-09-20	add notify syscall skeleton	Kimplul
	+ Now to actually start implementing shit. :)
2022-09-20	add capability subsystem and syscalls	Kimplul

2022-09-15	change syscalls to take 5 params and return 6	Kimplul
	+ In total, a syscall is built up of 6 values, with the first being the syscall number. Symmetrically, the first value is now a status and the following five values return "values". This allows us to cram in more info into the ipc_* functions. The performance difference is absolutely minimal, at least from my testing in qemu.
2022-09-15	add SYS_TICKS	Kimplul

2022-09-14	add putch syscall for easier userspace debugging	Kimplul
	+ Note that it is NOT intended for end user usage, just for debugging.
2022-06-12	doxygen shows no warnings	Kimplul
	+ Does not mean documentation is done, but it's a nice little achievement nonetheless.
2022-06-12	add license texts	Kimplul

2022-06-09	continue documentation	Kimplul

2022-05-29	modify formatting rules	Kimplul

2022-05-28	add sys_fwd and remove sys_req_*	Kimplul

2022-05-23	rename sys_switch to sys_swap	Kimplul

2022-05-22	add @file info to all files	Kimplul
	+ Next step, start documenting contents of each file.
2022-05-22	improved tcb handling in preparation for processes	Kimplul

2022-05-21	add create syscall for threads	Kimplul

2022-05-09	improve uapi	Kimplul

2022-05-05	riscv64 boots with clang (sort of)	Kimplul

2022-04-29	continue building base for irq handling	Kimplul

2022-04-23	ran clang-format	Kimplul

2022-04-21	use uint64_t for timer ticks	Kimplul
	+ GCC seems to provide this even on 32bit platforms, though I should really check.
2022-04-21	start working on timer subsys	Kimplul

2021-12-27	Started work on syscalls	Kimplul
