Bananymous e49d3c7bfe BuildSystem: We are now using cmake instead of plain make 
I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.

I wanted to rewrite the whole build system and changed to using cmake

:)

Bananymous eef3631a5a Kernel: Improve locking in Process, VFS and ATAController 
We used to block on all process access. This meant that shell
reading the keyboard input would block all VFS access making disk
accesses practically impossible. We now block only when it is
necessary :)

Bananymous 88ee35165f Kernel: Thread is no longer RefCounted 
This makes developement with Scheduler much easier against compiler
optimizations. I could now remove the pragma GCC optimize stuff.

Bananymous a24c2d9be2 Kernel: DeviceManager is now a 'FileSystem' so it can expose devices

Bananymous f4b4987d43 Kernel: Remove obsolete KeyboardLayout/ 
This was used by the old input system. Currently keyboard layout is
hardcoded to finnish. But it will be reworked as something read from
the filesystem

Bananymous 7f88ba70d4 Kernel: Add linecount.sh script

Bananymous ac094a48d6 Kernel: Rework the whole input system 
We now use Device abstraction that will allow us to provide devices
to userspace through /dev. Currently Shell reads from first and only
device (it being PS/2 Keyboard).

Bananymous d67de70126 Kernel: Process::working_directory() is now thread safe 
I realized you cannot return a stirng view and it to be thread safe
 2023-03-24 01:46:25 +02:00
Bananymous 6f334756c5 Kernel: Create RecursiveSpinLock and add it to Process 
We now lock every function within Proccess, just to be sure.
Recursive lock allows us to use lock from the same thread even if
we already have the spinlock locked
 2023-03-24 01:32:35 +02:00
Bananymous 310713d203 Kernel: Lock process functions instead of the ata controller 
Process has to use locks at least on some functions so multithreaded
disk io is safe. This seemed to fix corrupted reads from disk
 2023-03-24 01:17:39 +02:00
Bananymous 7d2ab53baa Kernel: Ext2FS now does allocations better 
We only have to allocate at the beginning of the all functions and
can properly exit before any disk reads if we run out of memory.

This makes development little bit 'harder' since the {read,write}_block
user must allocate a buffer of atleast block_size bytes.

I also made disk access to cause kernel panic on error since the error
handling during file write is something I don't want to think now.
The filesystem can easily corrupt so, I feel like when disk io starts
to fail I'll come back to this.
