2022-11-11less buggy forkKimplul
+ Not strictly done yet, but we can swap between two processes :D

2022-10-21beautificationKimplul
2022-10-21initial implementation of swapKimplul
+ Slightly unsure if it should be a syscall, or if assign would be enough. Also, which thread should run in a fork/spawn? For now, old thread, though this might increase latency. Or add swap flag to these calls?

2022-10-21slight optimisation to cur_tcb on riscvKimplul
2022-09-15change syscalls to take 5 params and return 6Kimplul
+ In total, a syscall is built up of 6 values, with the first being the syscall number. Symmetrically, the first value is now a status and the following five values return "values". This allows us to cram in more info into the ipc_* functions. The performance difference is absolutely minimal, at least from my testing in qemu.
2022-09-14add putch syscall for easier userspace debuggingKimplul
+ Note that it is NOT intended for end user usage, just for debugging.

2022-05-28implement set_ipc on riscvKimplul
2022-05-28start implementing new proc/rpc handlingKimplul
+ Essentially, separate root process and remote procedure call handling. I really should write down some documentation so I don't forget, but essentially: All threads share a common process virtual memory, and when a thread wants to make an rpc, it switches over to its own rpc vmem space that is linked to the remote process.
2022-05-24make process loading more genericKimplul
2022-05-23modify file genKimplul
2022-05-23new include structure, make parse easier for doxyKimplul
2022-05-23switch from clang-format to uncrustifyKimplul
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.
2022-05-22add @file info to all filesKimplul
+ Next step, start documenting contents of each file.
2022-05-22rename vm_branch to vmemKimplul
+ Closer to what it's for rather than what it is.
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
2022-04-29continue 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
2022-04-21use 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 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
