2022-09-20add notify syscall skeletonKimplul
+ Now to actually start implementing shit. :)
2022-09-20add capability subsystem and syscallsKimplul
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.
2022-09-15add SYS_TICKSKimplul
2022-09-14add putch syscall for easier userspace debuggingKimplul
+ Note that it is NOT intended for end user usage, just for debugging.
2022-09-14add canary to kernel stackKimplul
2022-09-14riscv32 boots and advances as far as riscv64Kimplul
2022-09-11change external directory structureKimplul
+ Prepare for possibly testing rv32 + Also remove newline from debugging output
2022-09-11allow building with riscv64-linux-gnuKimplul
+ May warn about PHDR not being in LOAD, there is a flag to silence it (--no-warn-rwx-segment) but it doesn't seem to exist in riscv64-unknown-elf for some reason.
2022-09-02reserve more space for fwKimplul
+ Doesn't seem to be specified anywhere, but I'll stick with 2MB for now, working on the assumption that the FW is at the start of the physical RAM. Possible TODOs: generate apos.its automatically from init.elf, allocate root_branch statically?

2022-06-12doxygen shows no warningsKimplul
+ Does not mean documentation is done, but it's a nice little achievement nonetheless.

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.

2022-05-23new 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.
