Bananymous 83e3409bd8 Kernel/LibC: Update SYS_SEEK to return new offset and implement lseek 2024-05-23 14:49:23 +03:00
Bananymous 7630170ed6 LibC: Implement qsort as quick sort 2024-05-23 14:44:48 +03:00
Bananymous 0af74fccda Kernel/LibC: Rework dirent structure 
dirent now contains statically sized d_name. This allows using
sizeof on the name and dirent properly, which some programs seem
to be using.

Bananymous e77de1804f Kernel: Fix some race conditions in TCP stack 
Remove race condition if two acks are to be sent one after another.

Always unblock semaphore once TCP thread has done something. This
allows better chance of TCP sending to succeed.

There are multiple places in the networking code that would require
thread-safe entering to blocking mode. I should add some API for this
so that a lot of race conditions could be removed.

Bananymous e00b92225d Kernel: Fix E1000 interrupt handling condition 
I had written the ICR register check backwards which lead to interrupt
handling only when it was not needed, and no handling when it was
needed. This somehow still worked, just much slower often requiring tcp
resends from the server.

Bananymous ee8fca9439 General: Update discord badge 2024-05-20 21:07:15 +03:00
Bananymous adc562feb8 General: Add simple contribution guide lines 
README now contains simple contribution guide lines that should be
followed. I am now more open for public contributions to the repo
if people are interested.

Create a discord server and link it to the README. Discord seems to be
a nice platform for general messaging.

Bananymous af8fa4014f BuildSystem: Always download cmake instead of using host's 
If cmake was installed from snap, build system would cause an error
because some libfakeroot GLIBC requirement.

Bananymous 08415b0e8f General: Remove submodule info from README 
Submodules are no longer needed as I now use my own AML interpreter instead of lai

Bananymous 7480e71801 BuildSystem: Download binutils and gcc as tar balls 
I am not sure why I changed this earlier. This is much cleaner and
faster as git doesn't have to recieve all patches and resolve deltas

Bananymous 0e405755ad General: Update README badge 
Tokei's own badge was kind unreliable and slow. I now parse the tokei output into json on server side and make shields.io query it.

Bananymous f9943b60e4 Kernel: Fix mutex try_lock return value 
WHY IS GCC NOT COMPLAINING FROM HEADERS... I used almost 2 hours
trying to locate why AML was broken

 2024-04-16 17:36:04 +03:00
Bananymous f1b2d7530d Kernel: Rework AML namespace and object hierarchy 
Remove tree-like structure from AML. This allows more spec compliant
parsing of named objects inside not yet declared devices.

This also allows AML to be run thread safely. All object adds/removes
are now guarded by a mutex.

Bananymous b6587b32b9 Kernel: ACPI ignore events from non-existent ports 2024-04-16 00:00:07 +03:00
Bananymous b89bafa165 Kernel: Add support for power button shutdown 
This patch implements basic support for power button using ACPI
fixed events. I still need to implement general purpose events
and embedded controller for full power button support.

Bananymous 9fac5f94ba Kernel: Fix entering ACPI mode 
My condition to check wheter to enter ACPI mode was incorrect.
I only entered ACPI mode if I already was in ACPI mode :DD

Spec says to load all tables with unique OEM table IDs but that seem
wrong.
