2021-09-11replace `user_ptr` with a linux-style `__user` annotationdzwdz
2021-08-24switch to using user_ptr for pointers coming from userlanddzwdz
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
2021-08-24replace () with (void) in function definitionsdzwdz
`()` means that any amt of arguments will be accepted, which isn't what i want
2021-07-26fork() pt 1: cloning process memorydzwdz
2021-07-24fix some warningsdzwdz
2021-07-24sysexit() now overrides all registersdzwdz
when doing anything more complex than starting a new program, you pretty much need to pass a full register dump. otherwise stuff will break
2021-07-24remove sysenter_setup from arch/generic.h - it's not even useddzwdz
2021-07-24save all registers on syscallsdzwdz
2021-07-23update the process' EIP/ESP when it syscallsdzwdz
2021-07-22implement the debuglog() syscalldzwdz
2021-07-21syscall parameter & return value passingdzwdz
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.
2021-07-21barebones syscalldzwdz
2021-07-20rename pagedir_use() to pagedir_switch()dzwdz
imo "use" was slightly misleading
2021-07-20global PAGE_MASK definedzwdz
it's pretty useful, so it makes sense to define it alongside PAGE_SIZE
2021-07-19very basic pagingdzwdz
2021-07-18clean up the linker script, remove duplicate labelsdzwdz
2021-07-18fix most current compiler warningsdzwdz
stack_top got changed into a char, because `extern void` isn't even valid. others are self-explanatory
2021-07-18move all kernel sources to src/kernel/dzwdz
