2022-05-22improved tcb handling in preparation for processesKimplul
2022-05-21add status info to memory mappingsKimplul
+ 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.
2022-05-21implement timers betterKimplul
2022-05-09improve uapiKimplul
2022-05-05fix makefiles on netbsdKimplul
+ 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.
2022-05-05riscv64 boots with clang (sort of)Kimplul
2022-04-29continue building base for irq handlingKimplul
2022-04-24fix rv32 compile errorsKimplul
2022-04-24start initial irq handlingKimplul
+ 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?)
2022-04-23ran clang-formatKimplul
2022-04-21fix warnings on 32bit riscvKimplul
+ Will most probably not work on 32bit, but nice to make 'portable' code.
2022-04-21use uint64_t for timer ticksKimplul
+ GCC seems to provide this even on 32bit platforms, though I should really check.
2022-04-21start working on timer subsysKimplul
2022-04-17expand sbi implementation a bitKimplul
2022-04-10add basic ubsan and fix issues reported by itKimplul
2022-04-10add clang format and run itKimplul
2022-03-01make vmflags_t 16 bitsKimplul
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)
2022-01-07Use #if defined(...) when not guard clauseKimplul
2022-01-07Modified pmem configuration handlingKimplul
2022-01-07Prefix static functions with __Kimplul
+ Probably completely unnecessary stylistic thing, but I'll roll with it
2022-01-07Moved debugging into debug.cKimplul
+ No clue why I had that stuff in common/main.c
2022-01-07Steps towards better status/debugging controlKimplul
2022-01-07Improved header dependency treeKimplul
2022-01-07Allow building with clangKimplul
+ 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)
2022-01-06Jump back to kernelspace testedKimplul
+ Added automated categories to debugging, bug/info/warn/error etc. Now I should just try to use them here and there :D
2021-12-29RefactoringKimplul
+ 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
2021-12-29Preparations for refactoringKimplul
2021-12-27Started work on syscallsKimplul
2021-12-26First useful jump to userspace!Kimplul
2021-12-23Fixups to four previous commitsKimplul
+ Christ, I'm shit at git etiquette
2021-12-23map_fill_region can now utilize higher order pagesKimplul
2021-12-23Added stat/mod_vmemKimplul
+ In general improved riscv vmem.c
2021-12-21Modified vmem internals to use pagesKimplul
2021-12-20Right up to init_proc, FUCK YEAHKimplul
+ Lots to do still, should keep a more detailed TODO.txt, among other things implement Sv48 support, make more things single truths etc.
2021-12-20More sensible initKimplul
+ Who knew some reservations were a good thing? (at least relativelyy speaking)
2021-12-20Revert "still some issues with vmem"Kimplul
This reverts commit 69d13626a37e33f31627a1144605a8fb93684d25.
2021-12-20still some issues with vmemKimplul
+ Not sure if I should go with noinit or init, fuck
2021-12-20Added init backKimplul
2021-12-19Add cpio newc format readerKimplul
+ Still need to actually add in an initrd that uses the format :D
2021-12-19Massive changes to jump to userspaceKimplul
2021-12-19[WIP] virtual memory managementKimplul
2021-12-08Added some C11 atomic operationsKimplul
Mainly to be used in spinlocks etc.
2021-10-26Identified issue with vmem implementationKimplul
+ Sensible mappings should help, discard what I wrote in the previous commit. Nothing works unless I get vmem up and running properly.
2021-10-25Some minor changes to virtual memory handlingKimplul
+ 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.
2021-10-19Initial virtual memory mapping functionsKimplul
2021-10-11Start designing vmem frameworkKimplul
2021-10-11Renamed [pv]addr_t to [pv]m_tKimplul
2021-10-11Moved some functions to common/Kimplul
2021-10-10Prepare proper jump to kernelKimplul
2021-10-01First 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
