2021-07-20 | global PAGE_MASK define | dzwdz | |
it's pretty useful, so it makes sense to define it alongside PAGE_SIZE | |||
2021-07-19 | fix some style inconsistenties | dzwdz | |
2021-07-19 | remove the unused r3_test function | dzwdz | |
2021-07-19 | very basic paging | dzwdz | |
2021-07-19 | add a page fault handler | dzwdz | |
2021-07-18 | basic executable loading | dzwdz | |
2021-07-18 | clean up the linker script, remove duplicate labels | dzwdz | |
2021-07-18 | fix most current compiler warnings | dzwdz | |
stack_top got changed into a char, because `extern void` isn't even valid. others are self-explanatory | |||
2021-07-18 | move the kernel linker script to src/kernel/ | dzwdz | |
2021-07-18 | move all kernel sources to src/kernel/ | dzwdz | |
2021-07-17 | detect the highest used memory address, and only allocate pages above it | dzwdz | |
2021-07-17 | Revert "debug code, verifies if the memory gets set up correctly" | dzwdz | |
not meant to be in the main tree, included for completeness | |||
2021-07-17 | debug code, verifies if the memory gets set up correctly | dzwdz | |
i guess that i can include this for completeness. if not for the awful pointer printing thingy this could probably get into the main version. TODO? | |||
2021-07-17 | basic boot module support | dzwdz | |
This loads a file from the boot disk into memory. Currently it just gets printed, but it's going to become a real executable soon. | |||
2021-07-17 | hacky function for logging pointers | dzwdz | |
2021-07-17 | rename _kernel_end to _bss_end | dzwdz | |
2021-07-17 | multiboot: manually address regions of the kernel | dzwdz | |
thanks to this, i can specify the region where the bss is - so GRUB won't place any boot modules there | |||
2021-07-10 | abstract away logging | dzwdz | |
Now, the kernel only interfaces with the architecture dependent stuff via functions declared in generic.h. I'll write a linter enforcing this soon. | |||
2021-07-10 | clean up the GDT initialization code | dzwdz | |
2021-07-10 | allocate the initial stack directly in linker.ld | dzwdz | |
IMO it's cleaner this way. I wanted to put it just under 1M, but it turns out that it isn't accessible at boot in QEMU. | |||
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 | |
