| 2021-09-04 | rename file descriptors to handles | dzwdz | |
| 2021-08-25 | remove FD_STDOUT | dzwdz | |
| init can just open `/tty` instead | |||
| 2021-08-25 | implement vfs_mount_seed, which creates the vfs passed to init | dzwdz | |
| 2021-08-24 | switch to using user_ptr for pointers coming from userland | dzwdz | |
| this avoid accidental dereferences, and now it's easy to tell apart which pointers are safe to directly read and which aren't. cons: - const is completely discarded | |||
| 2021-08-24 | replace () with (void) in function definitions | dzwdz | |
| `()` means that any amt of arguments will be accepted, which isn't what i want | |||
| 2021-08-24 | implement FD_SPECIAL_TTY, an stdout equalivent | dzwdz | |
| 2021-08-24 | add some scaffolding for file descriptors | dzwdz | |
| 2021-08-22 | basic mount resolving | dzwdz | |
| 2021-08-22 | process_switch_any: deduplicate some code | dzwdz | |
| 2021-08-22 | fix almost all compiler warnings | dzwdz | |
| 2021-08-18 | processes now store a PID for debugging purposes | dzwdz | |
| 2021-08-18 | fork(): store information about the parent too | dzwdz | |
| 2021-08-18 | rename process_clone to process_fork | dzwdz | |
| 2021-08-18 | store the processes as a tree instead of a list | dzwdz | |
| I'm about to need that for waits(). There's no single list of processes for simplicity's sake, but the search will now be even slower and it might even introduce a potential vuln! How fun! Someone could override stuff in .bss with random values. I'll either make gcc check if it hasn't gone past the end of the stack, or turn this into a non recursive function. | |||
| 2021-07-31 | kmalloc() and kfree() stubs | dzwdz | |
| 2021-07-26 | rename process_new() to process_seed() | dzwdz | |
| it's only meant to create the root process, the old name could've been misleading | |||
| 2021-07-26 | exit() now switches to the first running process | dzwdz | |
| i used a linked list because it's the simplest way to implement this | |||
| 2021-07-26 | fork() pt 1: cloning process memory | dzwdz | |
| 2021-07-24 | fix some warnings | dzwdz | |
| 2021-07-24 | sysexit() now overrides all registers | dzwdz | |
| when doing anything more complex than starting a new program, you pretty much need to pass a full register dump. otherwise stuff will break | |||
| 2021-07-24 | save all registers on syscalls | dzwdz | |
| 2021-07-21 | fix init stack alignment | dzwdz | |
| 2021-07-20 | per-process virtual memory | dzwdz | |
| VGA is only mapped into the virtual memory because there are no other ways of interacting with the OS. | |||
| 2021-07-18 | move all kernel sources to src/kernel/ | dzwdz | |
| 2021-07-10 | a sensible source structure | dzwdz | |
| The idea is that src/kernel/ is only allowed to interface with the hardware using whatever's defined in src/arch/generic.h. I'll probably write a small script for checking this later on. This is a giant commit so I've probably fucked something up. It boots fine on Bochs and QEMU, so at least there's that. | |||
| 2021-07-10 | separate the source code from object files; more modular Makefile | dzwdz | |
