Bananymous 26d9a3e253 Kernel: Move DeviceManager to its own file 2023-03-30 22:39:45 +03:00
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 c1dbafc101 BAN: StringView::split(char, bool) is now thread safe 
I had to duplicate some code, but this is better since I would like
to not use BAN::Function for something like this

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

Bananymous f4db246658 LibC: add ENOBUFS errno 2023-03-29 10:58:25 +03:00
Bananymous 7f90079ea7 Kernel: Fix keymap numlock behaviour 2023-03-29 03:18:22 +03:00
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
 2023-03-29 03:09:14 +03:00
Bananymous 7f88ba70d4 Kernel: Add linecount.sh script 
This calculates the number of lines of code in the whole project :D
 2023-03-29 03:06:57 +03:00
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
 2023-03-28 02:56:44 +03:00
Bananymous 0ef318633c BAN: ScopeGuard can now be disabled (it wont call the function) 2023-03-28 01:15:13 +03:00
Bananymous 2f8c9746e3 Kernel: Move ACPI to its own file 2023-03-27 17:30:45 +03:00

Bananymous 770f7716a0 Kernel: Rework processes and VFS so we don't expose inodes 
Everything is now done through a file descriptor.

Bananymous a011c0384f LibC: add dirent.h 2023-03-25 02:08:33 +02:00
Bananymous 0d356c5bbc LibC: Add stat structure 2023-03-24 18:08:22 +02:00
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
