kmi - ACTIVE - Kernel with migrating threads as IPC

Age	Commit message (Collapse)	Author
2022-05-22	add @file info to all files	Kimplul
	+ Next step, start documenting contents of each file.
2022-05-22	rename vm_branch to vmem	Kimplul
	+ Closer to what it's for rather than what it is.
2022-05-22	improved tcb handling in preparation for processes	Kimplul

2022-05-21	add status info to memory mappings	Kimplul
	+ next up would probably be to start working on process/thread relationships, largely as documented. Still not entirely sure about how I want to handle fork, but I suppose I might figure it out at some point.
2022-05-21	implement timers better	Kimplul

2022-05-12	initial workings of shared memory	Kimplul
	+ Should document this better but essentially a server requests a shared buffer, and chan then share this buffer to a thread. Freeing the buffer is done through normal means. MR_SHARED is used for buffers that are shared, and MR_OWNED tells whoever is freeing that region that it is allowed to free the physical memory behind the shared buffer.
2022-04-10	add clang format and run it	Kimplul

2022-03-01	make vmflags_t 16 bits	Kimplul
	lower 8 bits are reserved for arch-specific flags (but at least read/write/execute) and higher 8 bits are metadata, currently only for VM_VIRTUAL (to be used when the backing physical memory shouldn't be freed)
2022-01-07	Renamed region functions to not use sp_*	Kimplul

2022-01-07	Steps towards better status/debugging control	Kimplul

2022-01-07	Improved header dependency tree	Kimplul

2021-12-30	Add initial version of device memory mapping	Kimplul

2021-12-29	Refactoring	Kimplul
	+ Mainly just moving stuff out or arch/riscv/ that should be handled in common/ + Prepared separate process stack/call stack for server callbacks, rest to be implemeted soon ish
2021-12-27	Started work on syscalls	Kimplul

2021-12-26	First useful jump to userspace!	Kimplul

2021-12-23	map_fill_region can now utilize higher order pages	Kimplul

2021-12-23	Added stat/mod_vmem	Kimplul
	+ In general improved riscv vmem.c
2021-12-21	Modified vmem internals to use pages	Kimplul

2021-12-20	Right up to init_proc, FUCK YEAH	Kimplul
	+ Lots to do still, should keep a more detailed TODO.txt, among other things implement Sv48 support, make more things single truths etc.
2021-12-20	More sensible init	Kimplul
	+ Who knew some reservations were a good thing? (at least relativelyy speaking)
2021-12-20	Revert "still some issues with vmem"	Kimplul
	This reverts commit 69d13626a37e33f31627a1144605a8fb93684d25.
2021-12-20	still some issues with vmem	Kimplul
	+ Not sure if I should go with noinit or init, fuck
2021-12-20	Added init back	Kimplul

2021-12-19	Massive changes to jump to userspace	Kimplul

2021-12-19	[WIP] virtual memory management	Kimplul

2021-10-25	Some minor changes to virtual memory handling	Kimplul
	+ Should start to think about how virtual memory should be handled efficiently, I'm sort of flailing around and not actually doing anything beneficial. The mapping system I've so far implemented _works_, but it's not good and I'm not happy with it. I might come back and fix/improve it, but I think I'll go ahead and do other things for a while, might give me a better overhead view of what the virtual memory system should do. + TODO: should probably document the memory layout I'm going with at the moment.
2021-10-19	Initial virtual memory mapping functions	Kimplul

2021-10-11	Start designing vmem framework	Kimplul
