2023-06-08skip saving registers when possibleKimplul
2023-06-08add fast userspace return to do_ipcKimplul
2023-06-07change register save/load to increasing orderKimplul
2023-05-17align handle_irq to four byte boundaries alwaysKimplul
+ CSR_STVEC requires four byte alignment
2023-05-12fix LLVM compilationKimplul
+ RELEASE=1 doesn't work for some reason, though
2023-05-01update license stuffKimplul
2022-11-21make syscall handlers voidKimplul
2022-11-13~700k ipc requestsKimplul
+ 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.
2022-11-09add basic IPI structureKimplul
2022-10-21initial spawn implementationKimplul
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.
2022-09-14add canary to kernel stackKimplul
2022-06-12add license textsKimplul
2022-06-11continue documentationKimplul
2022-05-23modify file genKimplul
2022-05-23new include structure, make parse easier for doxyKimplul
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.
