kmi - ACTIVE - Kernel with migrating threads as IPC

Age	Commit message (Collapse)	Author
2022-01-06	Jump back to kernelspace tested	Kimplul
	+ Added automated categories to debugging, bug/info/warn/error etc. Now I should just try to use them here and there :D
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
2021-12-29	Preparations for refactoring	Kimplul

2021-12-27	Started work on syscalls	Kimplul

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

2021-12-23	Fixups to four previous commits	Kimplul
	+ Christ, I'm shit at git etiquette
2021-12-23	Added alloc_fixed_region	Kimplul
	+ Not used at the moment anywhere, but should come in handy when emulating stuff like (s)brk and when mapping ELF stuff
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	Started allowing higher order allocs	Kimplul

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	Added init back	Kimplul

2021-12-19	Add cpio newc format reader	Kimplul
	+ Still need to actually add in an initrd that uses the format :D
2021-12-19	Massive changes to jump to userspace	Kimplul

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

2021-10-26	Identified issue with vmem implementation	Kimplul
	+ Sensible mappings should help, discard what I wrote in the previous commit. Nothing works unless I get vmem up and running properly.
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

2021-10-11	Renamed [pv]addr_t to [pv]m_t	Kimplul

2021-10-11	Moved some functions to common/	Kimplul

2021-10-10	Prepare proper jump to kernel	Kimplul

2021-10-01	First jump to virtual memory!	Kimplul
	+ Lots of bughunting to do, probably lots of off-by-one and so on errors, and I make a lot of naive and possibly dangerous assumptions. But cool start nonetheless. Should also come up with some method of exchanging data between the init and actual kernel, probably some struct of some sort. TODO
2021-09-25	Used memory regions now marked	Kimplul
	+ I don't fully trust my memory management system yet, so should probably check the memory regions it gives.
2021-09-20	Some slight robustness improvements and obo errors	Kimplul

2021-09-19	Added fdt debug capability	Kimplul
	+ For future reference, apos now requires initrd to be found in fdt.
2021-09-12	Initial physical page manager	Kimplul
	+ Will probably still need a fair bit of tweakind and documentation improvements, but seems to work outside of the kernel. Also no valgrind errors, which is quite promising I guess.
2021-08-31	Improved linkind process, added padding generator	Kimplul

2021-08-30	Initial formatted debug output	Kimplul
	+ Mostly follows the POSIX printf, with the exceptions of no floating points and `X` signifies binary instead of uppercase hex
2021-08-26	Added debug flags and simple debug serial driver	Kimplul

2021-08-25	libfdt seems to work	Kimplul
	At least as far as reading memory info, cool. One issue I have is that .(ro)data is apparently accessed by absolute addresses, so I need to know at which address the kernel is going to be loaded. I would prefer completely position independent code, but if that's not possible then eh.
2021-08-22	Integrated libfdt	Kimplul
	+ Added new common/ directory, into which code that should be shared with init and kernel is to be added. Currently string.c and bytes.c. Code in common/ should be marked with __weak, so as to allow the arch to implement a better, more optimised version of the function if possible/required. + Created include/apos/types.h with macros essentially providing the libc limits.h and stdint.h. At the moment I use gcc/clang predefined macros for most things.
