Bananymous a24c2d9be2 Kernel: DeviceManager is now a 'FileSystem' so it can expose devices 
Shell reads keyboard through /dev/input :)

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 
This calculates the number of lines of code in the whole project :D

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 f9a0412e78 Kernel: ACPI unmap_header does not do anything 
We have to work with MMU mapping/unmapping to be user friendly

Bananymous 770f7716a0 Kernel: Rework processes and VFS so we don't expose inodes

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.

Bananymous 4fd21bc303 Kernel: Remove block group descriptor cache from ext2fs 
This will make improving the fs easier since we need to only update
the values on the disk

Bananymous 2ec18855f2 Kernel: TTY buffer is resized on font size change 
Shell also has better line wrapping. You still can't visually go
back to previous line, but atleas we now write from the beginning
of the line

Bananymous b222581d18 Kernel: Reading from fd verifies that file is opened for reading 2023-03-22 01:55:58 +02:00
Bananymous a8e3ee6f19 Kernel: Ext2 directory functions now fail on invalid blocks 
Invalid blocks should only happen while writing to a file and
I think in that case we should just bail out instead of giving
you incomlete inode list or search result.

Bananymous 22e45278a2 Kernel: Fix PC Screen font parsing 
I had misread the format and the parsing code was incorrect. I also
changed fonts to store unicode codepoints as 32 bit integers, so
every character can be represented
