| 2021-08-22 | await() 2: pass the exit message | dzwdz | |
| 2021-08-18 | await() 1: wait for child to die, without message passing | dzwdz | |
| The length is a int, because the syscall will have a signed output. A negative return value will mean an error (such as when it gets called by a childless process). | |||
| 2021-08-18 | fork() now has a return value; you can tell the child and parent apart | 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. | |||
| 2021-08-14 | init: add multipageify(), so i can test virt_iter in an simpler way | dzwdz | |
| 2021-08-12 | init: preserve registers in _syscall() | dzwdz | |
| 2021-08-11 | read _syscall_debuglog arguments across page boundaries | dzwdz | |
| 2021-07-31 | change the syscall naming convention; same one in kernel and userland | dzwdz | |
| 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 | |
| 2021-07-23 | add a barebones exit() syscall | dzwdz | |
| 2021-07-22 | don't map the VGA console buffer in user processes | dzwdz | |
| 2021-07-22 | implement the debuglog() syscall | dzwdz | |
| 2021-07-21 | syscall parameter & return value passing | dzwdz | |
| Sadly, sysenter on i386 limits me to only 4 arguments (so, 1 for the syscall id + 3 real args). If that turns out to be an issue I'll either just switch to interrupts, or switch to x64. | |||
| 2021-07-21 | barebones syscall | 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 | basic executable loading | dzwdz | |
