2024-12-08 | audio: Control master volume through /dev/volume | Anton Kling | |
2024-12-08 | kernel/libc: Add isdigit() | Anton Kling | |
2024-12-08 | kernel: Change error reporting for exec* | Anton Kling | |
2024-12-02 | ac97: Messy fixes to audio | Anton Kling | |
It seems to work completely now, but it is still very messy. | |||
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 | |||
2024-11-30 | ac97/audio: Add audio | Anton Kling | |
Incomplete but still very cool | |||
2024-11-30 | vfs: Move read() to vfs.c | Anton Kling | |
2024-11-29 | ext2: Handle "zero" blocks | Anton Kling | |
Any blocks with the value zero appear to indicate a region completly filled to zeros. I don't see this anywhere in the spec but it does make sense and the behavior matches files that I have on my FreeBSD machine so I guess it must be valid. | |||
2024-11-28 | changes | Anton Kling | |
2024-11-23 | vfs: Support O_TRUNC | Anton Kling | |
2024-11-23 | vfs: Add O_APPEND support + refactoring | Anton Kling | |
2024-11-22 | vfs: Add dup() | Anton Kling | |
2024-11-22 | vfs: Close new file descriptor if already in use when calling dup2 | Anton Kling | |
2024-10-30 | kernel: Improve error handling for OOM | Anton Kling | |
2024-10-30 | kernel/mmu: Make sure to check for NULL. | Anton Kling | |
2024-10-17 | kernel: Use realloc instead of malloc+free | Anton Kling | |
2024-10-16 | kernel: Add RSOD(red screen of death) | Anton Kling | |
This is not useful since 99% of the time I will have access to the serial output. But it does look cool. | |||
2024-10-14 | kernel: small bug fixes | Anton Kling | |
2024-10-14 | kernel: stuff | Anton Kling | |
2024-10-14 | TCP: Don't free buffer prematurely | Anton Kling | |
2024-10-12 | Kernel/MMU: Don't return non present pages unless creation is desired | Anton Kling | |
`get_page` is a horrible multipurpose function and at this point I am unsure what behavior I expect and have expected it to produce. Refactor should probably be done soon. | |||
2024-10-06 | Kernel/Networking: Modify outgoing packet in place | Anton Kling | |
This avoids creation of new buffers and unnecessary memcpys. The old interface still exists for UDP but will be removed when I am less lazy. From testing it does not appear to have any performance improvement but this is most likely due to other bottlenecks as extra copies should always be worse. | |||
2024-10-03 | kernel/shm: shm_open only create if O_CREAT was supplied | Anton Kling | |
2024-10-03 | libc: Add sendfile and queue | Anton Kling | |
2024-09-12 | Kernel: Add support for shebangs | Anton Kling | |
Adds support for shebangs (#!) that allow for things such as shell scripts without appending `sh` before the file. | |||
2024-08-17 | ext2: Bug fix. Incorrect assumption that `len` is not modified. | Anton Kling | |
I appear to have assumed that len would always be the number requested not the number left to be read. Therefore to get the number of bytes left ot read I did `len - rc` but the `- rc` was already accounted for by line 298. | |||
2024-07-11 | PCI: Fix bug not account for different bar index | Anton Kling | |
2024-07-08 | Kernel/Net: Don't use kmalloc to create send buffers | Anton Kling | |
Current method is also really bad since it uses multiple copies when it should instead just copy to the send buffer of the network card directly. But I have other things that I want to prioritize first. | |||
2024-07-08 | kmalloc: Merge headers more often | Anton Kling | |
2024-07-06 | Kernel: Add kmalloc scan | Anton Kling | |
This will scan for possible overflows in the program. It is a somewhat expensive operation but really useful for debugging. | |||
2024-07-06 | Kernel: Add queue syscall and improve TCP | Anton Kling | |
2024-07-06 | Kernel: Fix integer overflow | Anton Kling | |
2024-07-06 | Kernel: Fix sleep function to use uptime instead of UTC time | Anton Kling | |
2024-07-06 | Bug fix: Fix use after free when closing a pipe | Anton Kling | |
The other inode might already have been freed when close() is called. | |||
2024-07-05 | TCP: Add back support for listening on a socket | Anton Kling | |
2024-07-04 | scheduler: Use get_uptime() since it caches the result | Anton Kling | |
Apparently getting the current TSC is a expensive operation. This change had a significant improvements for I/O heavy applications. | |||
2024-07-04 | TCP: Allow delay for sends | Anton Kling | |
This is not at all optimal for applications that already buffer their data but can have a huge impact on those that don't. Applications that don't wish to use this should disable this for their socket. | |||
2024-07-04 | PIT: Fix dumb bug | Anton Kling | |
The incorrect timer was being used for TCP ACK flush | |||
2024-07-04 | Random: Improve random seeding. | Anton Kling | |
Now it appears to be sufficiently good at producing a distinct seed at each boot without using a /etc/seed file. Previously it did not do this. Of course this is nowhere near cryptographically secure but randomness does assist with things such as kmalloc. | |||
2024-07-04 | CMOS: Make read/write calls async | Anton Kling | |
This can speed up boot times since CMOS would otherwise have to wait before it could perform a read/write call. Now it gets triggered by a interrupt. | |||
2024-07-03 | Kernel/Time: Improve time keeping | Anton Kling | |
This makes use of TSC and now provides a file system interface for userland programs to change the system time. | |||
2024-07-03 | CMOS: Add basic CMOS RTC support | Anton Kling | |
2024-07-03 | Kernel: Add simple support for timer using TSC | Anton Kling | |
2024-07-02 | TCP: Increase the receive buffer significantly | Anton Kling | |
2024-07-02 | ahci: Bug fix, turns out the async optimization does not work that well | Anton Kling | |
2024-07-01 | Bug fix: avoid use after free | Anton Kling | |
2024-07-01 | VFS: Move towards unifying vfs_inode_t and vfs_fd_t | Anton Kling | |
There is no need for these to be seperate. They will probably move to the same struct soon. | |||
2024-06-30 | ahci/ext2: small fixes | Anton Kling | |
2024-06-30 | Kernel: cleanup | Anton Kling | |
2024-06-30 | UBSAN: Add more ubsan handlers | Anton Kling | |
