| 2022-12-01 | start looking into memory handling | Kimplul | |
| + Now 10M alloc/frees succeed, which totals more memory than the virtual machine has, so no too obvious leaks are occuring. For future debugging speed, changed 10M to 1M. + Also quick fix to rpcs, stacks are now assigned. Not entirely sure why they worked before this, but good that I found it. | |||
| 2022-11-21 | possible optimisations | Kimplul | |
| 2022-10-22 | initial high level fork imp | Kimplul | |
| 2022-10-14 | add spawn syscall | Kimplul | |
| + Prefer over unixy fork/exec for speed since I don't want to support cow. Shell redirection should be done with env server and cooperating libc. | |||
| 2022-09-22 | add assign syscall skeleton | Kimplul | |
| 2022-09-20 | add notify syscall skeleton | Kimplul | |
| + Now to actually start implementing shit. :) | |||
| 2022-09-20 | add capability subsystem and syscalls | Kimplul | |
| 2022-09-15 | change syscalls to take 5 params and return 6 | Kimplul | |
| + 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. | |||
| 2022-09-15 | add SYS_TICKS | Kimplul | |
| 2022-09-14 | add putch syscall for easier userspace debugging | Kimplul | |
| + Note that it is NOT intended for end user usage, just for debugging. | |||
| 2022-06-12 | add license texts | Kimplul | |
| 2022-06-09 | continue documentation | Kimplul | |
| 2022-06-08 | continue documentation | Kimplul | |
| 2022-05-28 | add sys_fwd and remove sys_req_* | Kimplul | |
| 2022-05-23 | new include structure, make parse easier for doxy | Kimplul | |
| 2022-05-23 | rename sys_switch to sys_swap | Kimplul | |
| 2022-05-22 | add @file info to all files | Kimplul | |
| + Next step, start documenting contents of each file. | |||
| 2022-05-22 | improved tcb handling in preparation for processes | Kimplul | |
| 2022-05-21 | add create syscall for threads | Kimplul | |
| 2022-05-05 | riscv64 boots with clang (sort of) | Kimplul | |
| 2022-04-29 | continue building base for irq handling | Kimplul | |
| 2022-04-21 | use uint64_t for timer ticks | Kimplul | |
| + GCC seems to provide this even on 32bit platforms, though I should really check. | |||
| 2022-04-21 | start working on timer subsys | Kimplul | |
| 2021-12-27 | Started work on syscalls | Kimplul | |
