| 2021-08-09 | silence the QEMU debug output | dzwdz | |
| i'm using bochs for debugging now anyways, and this will be useful for serial output | |||
| 2021-08-09 | a sloppy implementation of path_simplify() | dzwdz | |
| it's kinda bad. it passes the tests, though... | |||
| 2021-08-08 | path_simplify now returns int, has better tests | dzwdz | |
| 2021-08-08 | Merge branch 'main' of github.com:dzwdz/camellia | dzwdz | |
| 2021-08-07 | build all parts of the toolchain to the same $PREFIX | dzwdz | |
| If gcc is built with a different $PREFIX than binutils, it won't even attempt using them - it will use the system assembler instead, which fails for obvious reasons. | |||
| 2021-08-06 | a (seemingly broken) gcc build script | dzwdz | |
| It compiles, but the resulting gcc binary doesn't actually work. Maybe it's too new for the binutils? | |||
| 2021-08-06 | quit the binutils build script if an error occurs | dzwdz | |
| 2021-08-05 | add a script which builds i686-elf-binutils | dzwdz | |
| 2021-08-04 | partial path_simplify implementation | dzwdz | |
| it currently only checks if the path is valid, it's the bare minimum needed to write tests | |||
| 2021-08-04 | rename TEST_IF to TEST_COND | dzwdz | |
| i'll be adding a TEST_STR macro soon, so TEST_COND makes more sense | |||
| 2021-08-03 | remove the dummy kernel test | dzwdz | |
| what's the point, we have real tests now | |||
| 2021-08-03 | fix inconsistent semicolons | dzwdz | |
| 2021-08-03 | kernel: implement static_strcmp() | dzwdz | |
| will be used to test functions operating on strings | |||
| 2021-08-03 | kernel: implement memcmp | dzwdz | |
| 2021-08-03 | a bad testing framework | dzwdz | |
| 2021-08-03 | put the NUM2STR macro in util.h | dzwdz | |
| i'll use it outside of panic.h | |||
| 2021-07-31 | fix formatting in github's viewer thingy | dzwdz | |
| 2021-07-31 | draft out a simple overview of the VFS | dzwdz | |
| i'm a terrible writer | |||
| 2021-07-31 | try documenting the syscalls (and fail badly) | dzwdz | |
| 2021-07-31 | change the syscall naming convention; same one in kernel and userland | dzwdz | |
| 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 | |
| 2021-07-26 | mark sc_exit() as noreturn | dzwdz | |
| gets rid of the double panic() call | |||
| 2021-07-25 | print a heart on boot | dzwdz | |
| 2021-07-24 | fix some warnings | dzwdz | |
| 2021-07-24 | make the Makefile show almost nothing except warnings/errors | 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 | add a barebones exit() syscall | dzwdz | |
| 2021-07-23 | update the process' EIP/ESP when it syscalls | dzwdz | |
| 2021-07-22 | don't map the VGA console buffer in user processes | 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 init stack alignment | 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 | |
| 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. | |||
| 2021-07-20 | rename pagedir_use() to pagedir_switch() | dzwdz | |
| imo "use" was slightly misleading | |||
| 2021-07-20 | only enable paging when jumping into ring 0 | dzwdz | |
| The kernel can't use the limited paging tables of user processes. Alternatively, sysenter could accept a parameter with a new cr3. That would allow/require using paging in the kernel - so I'll switch to it later, but I want to get other stuff done first. | |||
| 2021-07-20 | global PAGE_MASK define | dzwdz | |
| it's pretty useful, so it makes sense to define it alongside PAGE_SIZE | |||
