| 2021-10-07 | kernel/i386: fix port_in16's return value size | dzwdz | |
| 2021-10-07 | kernel/i386: add 16bit port io functions | dzwdz | |
| 2021-10-07 | kernel/i386: rename the port io functions with their bit length | dzwdz | |
| 2021-10-06 | kernel/i386: implement part of ATA IDENTIFY | dzwdz | |
| 2021-10-05 | isr: simplify the exception handler | dzwdz | |
| 2021-10-05 | kill the process that caused an exception instead of panicking | dzwdz | |
| 2021-10-02 | implement serial/tty input | dzwdz | |
| 2021-10-02 | serial: implement a selftest | dzwdz | |
| 2021-10-02 | rename kernel/arch/log.h to io.h | dzwdz | |
| it's not related to logging but to general io, the old name didn't make sense | |||
| 2021-09-21 | start using sparse's `-Wnon-pointer-null` | dzwdz | |
| While I personally don't see a reason to use NULL instead of 0, I assume that whoever made that a sparse default knew what they were doing. | |||
| 2021-09-21 | start using sparse's `-Wdecl` | dzwdz | |
| 2021-09-20 | create a few specialized panic()s | dzwdz | |
| thanks to this i can tell which ones are placeholders, and which ones should stay | |||
| 2021-09-19 | call sysenter_setup before kmain_early | dzwdz | |
| makes the code slightly simpler, imo | |||
| 2021-09-18 | merge `kernel/types.h` and `init/types.h` | dzwdz | |
| 2021-09-14 | merge the `syscall_handler` and `_syscall` declarations | dzwdz | |
| i think that making the call a bit more "transparent" makes the code nicer | |||
| 2021-09-14 | add support for 4-parameter syscalls | dzwdz | |
| 2021-09-12 | log cr2 on page faults | dzwdz | |
| 2021-09-12 | make the inline functions static | dzwdz | |
| otherwise this doesn't compile with -O0 | |||
| 2021-09-11 | replace `user_ptr` with a linux-style `__user` annotation | dzwdz | |
| 2021-09-11 | fix the `sparse` warnings | dzwdz | |
| 2021-09-05 | move most of the memory stuff to kernel/mem/ | 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 | |||
| 2021-08-22 | kernel: implement assert | dzwdz | |
| 2021-08-18 | "fix" _tty_hex and _tty_var | dzwdz | |
| well i guess it compiles now | |||
| 2021-08-10 | fix typo referring to unexistent function | dzwdz | |
| 2021-08-10 | statically assert that the pointer size == 4 bytes | dzwdz | |
| 2021-08-09 | move the x86 port io code to a separate file | dzwdz | |
| 2021-08-09 | print the boot heart on both VGA and serial | dzwdz | |
| 2021-08-09 | vga tty: vga_putchar is now static | dzwdz | |
| 2021-08-09 | implement serial output | dzwdz | |
| 2021-08-09 | rename `log_` to `tty_`, `tty_` to `vga_` | dzwdz | |
| 2021-08-09 | move all the tty stuff to a tty directory | dzwdz | |
| 2021-07-26 | fork() pt 1: cloning process memory | dzwdz | |
| 2021-07-24 | fix some warnings | dzwdz | |
| 2021-07-24 | simplify the struct copy in sysexit() | dzwdz | |
| 2021-07-24 | sysenter: save the registers into _sysexit_regs, makes the code cleaner (imo) | dzwdz | |
| 2021-07-24 | merge the `register` and `register_pushad` structs | 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 | remove sysenter_setup from arch/generic.h - it's not even used | dzwdz | |
| 2021-07-24 | save all registers on syscalls | dzwdz | |
| 2021-07-23 | update the process' EIP/ESP when it syscalls | dzwdz | |
| 2021-07-22 | disable paging when handling interrupts | dzwdz | |
| The kernel code assumes that paging is always disabled. I've also added a bit of comments to the assembly / ruined the git blame. | |||
| 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 | |
| 2021-07-21 | fix sysenter()'s stack argument | dzwdz | |
| It was taken from the wrong place - also I don't think that functions should change their EIP in the first place? | |||
| 2021-07-21 | simplify the IDT generation | dzwdz | |
| 2021-07-21 | create ISR stubs, which call a single main isr handler | dzwdz | |
| quick explaination of how this even works: The `call` in each stub pushes its own address onto the stack before calling stage2. We can substract the address of the 0th ISR to get the offset, which we then divide by the size of each stub to get the index. | |||
| 2021-07-20 | remove an already finished TODO | dzwdz | |
