| 2023-11-10 | Kernel: Remove old dead code | Anton Kling | |
| 2023-11-10 | Kernel/fs: Dynamically allocate based upon file size. | Anton Kling | |
| This commit also changes "unsigned char" to "char". A slight step in the direction of making my coding style less bipolar. | |||
| 2023-11-09 | Kernel/fs: Dynamically allocate depending upon file size of directory. | Anton Kling | |
| This also solves a bug where the data_p pointer could get out of range due to incorrect assumptions being made about the ext2 directory layout. To be fair even a faulty ext2 directory layout should not be able to cause memory bugs. | |||
| 2023-11-09 | Kernel: Remove old comment | Anton Kling | |
| 2023-11-09 | Kernel: Initalize the file descriptor pointers in the proess struct to | Anton Kling | |
| zero. | |||
| 2023-11-08 | Kerenl/MMU: Remove dumb bug as a result of uninitalized memory | Anton 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. | |||
| 2023-11-08 | 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. | |||
| 2023-11-08 | Meta: Modify run and debug scripts | Anton Kling | |

| 2023-11-08 | Kernel/MMU: Create a seperate table for heap allocation | Anton Kling | |
| 2023-11-06 | Userland: Remove old coreutil applications that have moved to minibox | Anton Kling | |
| 2023-11-01 | Kernel: Add a simple TCP implementation | Anton Kling | |
| 2023-10-31 | ante: Adjust X position of cursor so it can always land on a line. | Anton Kling | |
| If a y position is found for the cursor we will adjust the X position to the optimial position. Previously if you tried to move from the end of a long line to a short line it would not work since a valid X position could not be found. | |||
| 2023-10-31 | Kernel: Remove all O0 optimizations on functions. | Anton Kling | |
| The kernel can now fully compile under O3 without any noticable problems :) | |||
| 2023-10-31 | Kernel: Bug fix, infinite loop when checking string memory permissions | Anton Kling | |
| If the string is pointed to a very exact location in memory the loop never finishes. | |||
| 2023-10-31 | Meta: Sync the sysroot after running the VM | Anton Kling | |
| 2023-10-31 | WindowServer: Make the mouse dotted to make it visible on all backgrounds | Anton Kling | |
| 2023-10-31 | Meta: Fix build scripts to work on debian | Anton Kling | |
| 2023-10-31 | Meta: Create a simple toolchain compilation script | Anton Kling | |
| 2023-10-31 | Meta: Create simple build scripts for kernel, userland and general enviroment | Anton Kling | |
| 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. | |||
| 2023-10-30 | Cleanup of things that did not get formatted or not included in old commits | Anton Kling | |
| 2023-10-30 | LibC: Remove header files that are not in the "include" directory | Anton Kling | |
| 2023-10-30 | LibC: Don't fail if a free() is done that the wrong address location. | Anton Kling | |
| 2023-10-30 | Kernel/LibC: Add signals and support for custom signal handlers to processes. | Anton Kling | |
| 2023-10-30 | LibC: Bug fix, make sure to invalidate cache if it skips using it | Anton Kling | |
| Since when the cache gets skipped the offset in the file increases far outside of the reach of the current cache. Therefore the current cache should be discarded. | |||
| 2023-10-30 | LibC: Skip using cache if length requested is longer than the cache block | Anton Kling | |
| This avoid a bunch of extra systemcalls that would have to be made to read each portion into a cache block. | |||
| 2023-10-30 | EXT2: Improve block cache | Anton Kling | |
| This significantly speeds up certain operations as indirect block looksup now don't need to make as many requests to the hard drive. | |||
| 2023-10-30 | Kernel/LibC/Networking: Be able to send UDP messages | Anton Kling | |
| Now it can send UDP messages to a specific IP address and libc has enough to create a basic UDP ECHO server, that is kinda cool. | |||
| 2023-10-30 | Kernel: Expose source information of incoming UDP packets | Anton Kling | |
| 2023-10-30 | Kernel: Move min, max functions to their own file | Anton Kling | |
| 2023-10-30 | LibC: Optimize memcpy function | Anton Kling | |
| Instead of copying byte by byte it now copies in 64, 32, 16, 8 bit chunks. | |||
| 2023-10-30 | Kernel/Networking/LibC: Add syscalls and libc functions for UDP | Anton Kling | |
| This allows a UDP server to be created in userland and read data. Currently it can't send data and is very very simplistic. Code is horrible and probably needs some fixing until it can be further built upon. | |||
| 2023-10-30 | Kernel: Fixup rtl8139, add basic ARP and ethernet support | Anton Kling | |
| Currently the ARP appears to be able to respond to requests. | |||
| 2023-10-30 | Build system: Remove the network cards from as where only for testing | Anton Kling | |
| 2023-10-30 | Kernel: Add basic support for PCI and rtl8139 | Anton Kling | |
| This implementation is very messy and is currently not used. | |||
| 2023-10-30 | RTL8139: Transmission and interrupts seem to magically work now. | Anton Kling | |
| This commit is done to preserve the functional code before I make new changes. | |||
| 2023-10-30 | Kernel: Add basic PCI and very basic rtl8139 support | Anton Kling | |
| 2023-10-24 | Add ftruncate syscalls that I forgot to add | Anton Kling | |
| 2023-10-24 | ante: Truncate the file before writing to it. | Anton Kling | |
| Previously the file size would not decrease even if data was deleted. | |||
| 2023-10-24 | EXT2: Add truncate function to filesystem | Anton Kling | |
| 2023-10-24 | VFS/LibC: Create ftruncate function and corresponding syscall and libc ↵ | Anton Kling | |
| implementation Previously this function was only used for shared memory region created by shm_open because I was lazy. Now exists for all files. | |||
| 2023-10-24 | Scheduler/MMU: Include length variable in structure that did not get ↵ | Anton Kling | |
| included in previous commit | |||
| 2023-10-24 | LibC: Allocate stdin, stdout, stderr on the heap so they can be closed with ↵ | Anton Kling | |
| fclose | |||
| 2023-10-24 | WindowServer: Optimize 'for' loop such that it avoids doing a division ↵ | Anton Kling | |
| during each iteration | |||
| 2023-10-24 | WindowServer: Don't hardcode the display resolution | Anton Kling | |
| 2023-10-23 | EXT2: Use the vfs_create_inode function to create the mount | Anton Kling | |
| 2023-10-23 | VFS/libc: Create a syscall for mkdir and add the function to libc | Anton Kling | |
| 2023-10-23 | EXT2: Make a function for directory creation and refactor directory entry ↵ | Anton Kling | |
| creation code | |||
| 2023-10-23 | ante: Make use of the LibGUI event loop. | Anton Kling | |
