| 2024-12-12 | formatting: Use clang-format on all projects | Anton Kling | |
| This commit also add braces to all `if` statements. | |||
| 2024-12-10 | kernel: Add string view and string builder | Anton Kling | |
| This makes write/read calls that use strings to communicate much simpler and less error prone. | |||
| 2024-12-09 | kernel: Add a way to parse numbers from C strings | Anton Kling | |
| After making this change I am now actually doubting if using C strings is a good idea and maybe it should just always just the string view library that userland makes use of. But old code and the upcoming commits rely upon this so it is a change my future less lazy self will do. | |||
| 2024-12-09 | mmu: Make certain allocations physical and virtual mapping linear | Anton Kling | |
| Previously it was possible for fragmentation to occur and as a result certain allocations would have a linear virtual address space but not a linear physical address space. This is bad since a lot of calls to kmalloc_align rely upon both being linear, it has now been changed such that all allocations done by kmalloc_align now guarantee this mapping holds for both virtual and physical addresses. It was due to oversight and sheer luck that this had been working for so long. | |||
| 2024-12-08 | kernel/libc: Add isdigit() | Anton Kling | |
| 2024-11-30 | kernel: Change math.h to use macros | Anton Kling | |
| Having min/max be functions was a stupid decision in the first place | |||
| 2024-06-26 | Kernel: Move all syscalls into one file | Anton Kling | |
| 2024-06-22 | Kernel: Use correct types for syscall | Anton Kling | |
| The previous type was a 64 bit which causes problems for the syscall calling interface. | |||
| 2024-04-29 | Kernel/Socket: Move sockets back to being file descriptors | Anton Kling | |
| 2024-04-26 | Kernel: More out of memory condition checks | Anton Kling | |
| 2024-04-26 | Kernel: Handle userspace memory errors instead of crashing. | Anton Kling | |
| The kernel should kill the process if it has memory issues. | |||
| 2024-04-22 | MMU: Extra asserts to avoid future regressions | Anton Kling | |
| 2024-04-18 | LibC/Kernel: Move lseek/seek to kernel | Anton Kling | |
| 2024-04-17 | Kernel/LibC: Add fstat() and remove stat() syscall | Anton Kling | |
| 2024-04-13 | Kernel: Don't hard fail if the kernel can't allocate memory. | Anton Kling | |
| Currently this is just a improvement of error handling but it should also try to free up memory where it is possible. | |||
| 2024-04-12 | Kernel/MMU: Dellocate pagedirectory when process exits. | Anton Kling | |
| 2024-04-11 | bug fixes | Anton Kling | |
| 2024-04-02 | Kernel: Fix some memory leaks | Anton Kling | |
| 2024-03-26 | Increase support for signals | Anton Kling | |
| 2024-03-25 | Random changes | Anton Kling | |
| 2024-03-20 | MMU: Fixed massive problem in assumption of RAM layout | Anton Kling | |
| This caused certain addreses which where not RAM memory to be assigned to virtual addresses incorrectly. This caused a significant slowdown when running it with KVM due to constantly having to exit the VM if the OS writes to memory that is not RAM. This fix increased the performance of KVM significantly and improved TCG performance. | |||
| 2024-03-14 | random changes made | Anton Kling | |
| 2024-02-07 | Add enable/disable interrupts function | Anton Kling | |
| This is to reduce usage of inline assembly | |||
| 2024-02-07 | A lot of small changes | Anton Kling | |
| 2023-11-28 | Meta: Apply new clang-format rules to kernel | Anton Kling | |
| 2023-11-28 | Kernel: Add basic IPC and move to microkernel design. | Anton Kling | |
| The IPC design is currently a WIP and is nowhere near complete | |||
| 2023-11-24 | Refactor write() and pwrite() | Anton Kling | |
| 2023-11-24 | Refactor open() | Anton Kling | |
| 2023-11-23 | Kernel/LibC: Add randomfill() syscall. | Anton Kling | |
| This syscall aims to fill the given buffer with cryptographically secure random data. If the syscall returns and does not cause a page fault it will **always** have filled the buffer with random data and never gives back any error value. | |||
| 2023-11-22 | Meta: Cleanup of header files such that they are partially shared | Anton Kling | |
| The /include directory contains definitons that both the kernel and libc need to be in sync. | |||
| 2023-11-17 | Kernel: Add isatty syscall | Anton Kling | |
| 2023-11-16 | Kernel: Change how syscalls are built and implemented. | Anton Kling | |
| 2023-11-15 | Add untracked files | Anton Kling | |
| 2023-11-15 | VFS: Add stat | Anton Kling | |
| 2023-11-13 | Kernel: Add typedefs.h | Anton Kling | |
| 2023-11-12 | AHCI: Add very basic AHCI and some additional helper functions to mmu.c | Anton 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. | |||
| 2023-11-10 | Kernel Style: Change uint*_t -> u* | Anton Kling | |
| 2023-11-08 | Kernel/MMU: Detect system memory and dynamically adjust memory usage available | Anton Kling | |
| Previously this would be hardcoded but now it can be detected by the bootloader and passed in via the multiboot header. | |||
| 2023-10-31 | Meta: 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. | |||
