2023-11-15Meta: Setup a drive over AHCIAnton Kling
2023-11-13Memory: Fix problem where certain tables did not get marked as kernel.Anton Kling
This caused the tables to be cloned instead of having the pointer copied on the new page directory creations. This is just a solution to the symptom of having a bad design for memory managment. Maybe I will figure out something better.
2023-11-13Crypto: Implement fast insecure RNG for overwritting memory areas.Anton Kling
This is mainly done to test for uninitlalized memory and find bugs faster. Therefore it does not need to be cryptographically secure or perfectly uniform. Xoshiro256++ seems like a good fit.
2023-11-12AHCI: Add very basic AHCI and some additional helper functions to mmu.cAnton Kling
Currently certain parts of the code are taken from osdev wiki as there seems to be very little documentation that I can find on how H2D FIS is structured. Those parts, especially some of the uglier parts of the example code will be rewritten/changed.
2023-11-10Kernel Style: Change uint*_t -> u*Anton Kling
2023-11-10Kernel/Memory: Fill new allocations with random data.Anton Kling
This should make it easier to spot uninitalized memory being used.
2023-11-09Kernel: Remove old commentAnton Kling
2023-11-08Kerenl/MMU: Remove dumb bug as a result of uninitalized memoryAnton Kling
The kernel would randomly crash. Turns out I did not zero out the frames so my page allocator seemed to get into some weird state.
2023-11-08Kernel/MMU: Detect system memory and dynamically adjust memory usage availableAnton Kling
Previously this would be hardcoded but now it can be detected by the bootloader and passed in via the multiboot header.
2023-11-08Kernel/MMU: Create a seperate table for heap allocationAnton Kling
2023-10-31Kernel: Remove all O0 optimizations on functions.Anton Kling
The kernel can now fully compile under O3 without any noticable problems :)
2023-10-31Kernel: Bug fix, infinite loop when checking string memory permissionsAnton Kling
If the string is pointed to a very exact location in memory the loop never finishes.
2023-10-31Meta: Move kernel and userland to their own folders.Anton Kling
This is to allow both the kernel and the userland to share certain header files and to make the folder structure a bit more clear.
