kmi - ACTIVE - Kernel with migrating threads as IPC

Age	Commit message (Collapse)	Author
2024-11-02	allow skipping some cache flushes in proc	Kimplul

2024-07-07	misc fixes	Kimplul
	+ Align kernel to 2MiB boundary in u-boot + Optimize alignment functions a little bit, should still have to check on real hardware but 'feels' more clean + Add early boot debugging + Put extra cores we aren't ready to account for to sleep if/when they boot. + Make BASE_PAGE_SIZE constant on riscv64/32, helps the compiler with some alignment checks among other things.
2024-07-06	pretty massive virtual memory rewrite	Kimplul
	+ The system is now a bit simpler and hopefully easier to understand, while also extending the shared memory to be 1:N, where there is one owner who may become a zombie while waiting for the N to die.
2023-10-09	experimenting with removing lists threads per proc	Kimplul
	+ Gives a very slight improvement to RPC speeds, but mostly cleans up code a little bit.
2023-10-09	move rpc stack handling to arch-specific code	Kimplul
	+ Fairly considerable speedup, as we don't have to look up the rpc pte every time separately, instead cacheing them. Adds an architecture specific limitation to total rpc stack size, though.
2023-05-01	update license stuff	Kimplul

2023-04-30	rename to kmi	Kimplul

2022-11-13	improve documentation on new features	Kimplul

2022-11-13	~700k ipc requests	Kimplul
	+ Eliminated need for save/load_regs, now the register save area is behind a pointer which _slightly_ increases overall syscall delay, but speeds up ipc requests by a fair bit.
2022-06-12	add license texts	Kimplul

2022-05-29	continue documentation efforts.	Kimplul

2022-05-28	continue documenting source	Kimplul

2022-05-24	make process loading more generic	Kimplul

2022-05-24	initial musings about exec	Kimplul

2022-05-23	start writing documentation	Kimplul

2022-05-23	new include structure, make parse easier for doxy	Kimplul

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.
2022-05-22	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.
2022-05-21	implement timers better	Kimplul

2022-05-05	fix makefiles on netbsd	Kimplul
	+ Doesn't quite compile all the way unfortunately, building the GNU toolchain on NetBSD is a bit more difficult than I was expecting. LLVM does compile, but fails to link for some reason.
2022-04-29	continue building base for irq handling	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

2022-04-21	fix warnings on 32bit riscv	Kimplul
	+ Will most probably not work on 32bit, but nice to make 'portable' code.
2022-04-17	expand sbi implementation a bit	Kimplul

2022-04-10	add clang format and run it	Kimplul

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

2022-01-07	Modified pmem configuration handling	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)
