kmi - ACTIVE - Kernel with migrating threads as IPC

Age	Commit message (Collapse)	Author
2022-05-23	switch from clang-format to uncrustify	Kimplul
	The output is close enough, and I like that uncrustify is a third-party tool, so people can install a single tool for formatting instead of having to lug around a whole toolchain. I fully expect to have to add settings to uncrustify.conf, but let's see how this goes.
2022-05-23	make syntax friendlier for uncrustify	Kimplul

2022-05-23	rename sys_switch to sys_swap	Kimplul

2022-05-22	apply slight doxygen formatting improvements	Kimplul

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	start testing out doxygen	Kimplul

2022-05-22	improved tcb handling in preparation for processes	Kimplul

2022-05-21	add create syscall for threads	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.
2022-05-09	improve uapi	Kimplul

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

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

2022-04-24	fix rv32 compile errors	Kimplul

2022-04-24	start initial irq handling	Kimplul
	+ Still lots todo, and I'm not entirely sure how I should handle program space switches (mainly since the kernel uses the process' stack, maybe it shouldn't?)
2022-04-23	ran clang-format	Kimplul

2022-04-23	change alignment functions to be type generic	Kimplul

2022-04-21	fix warnings on 32bit riscv	Kimplul
	+ Will most probably not work on 32bit, but nice to make 'portable' code.
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

2022-04-17	expand sbi implementation a bit	Kimplul

2022-04-17	improve node subsys	Kimplul
	+ More robust alignment and less memory usage for status, from enum to bit
2022-04-16	initial thread id handling	Kimplul
	+ At least initial in the sense that this seems like the smartest way to handle things, that is.
2022-04-16	create more general node structure	Kimplul
	+ Allow for easier handling of other subsystems that want to use nodes, mainly tcb and possibly dev_mem
2022-04-10	add basic ubsan and fix issues reported by it	Kimplul

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)
2022-01-13	O(1) memory region node allocation	Kimplul

2022-01-07	Use #if defined(...) when not guard clause	Kimplul

2022-01-07	Merged bits.h and bytes.h	Kimplul

2022-01-07	Modified pmem configuration handling	Kimplul

2022-01-07	Renamed region functions to not use sp_*	Kimplul

2022-01-07	Moved debugging into debug.c	Kimplul
	+ No clue why I had that stuff in common/main.c
2022-01-07	Steps towards better status/debugging control	Kimplul

2022-01-07	Improved header dependency tree	Kimplul

2022-01-07	Allow building with clang	Kimplul
	+ Release mode is sort of broken, as lto doesn't work with linker relaxation and turning the relaxation off causes issues with the jump from init to kernel (as I've currently implemented it, could probably be fixed with a manual jump from assembly, I'll add it to my TODO list)
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	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.
