Bananymous 766439db6d Kernel: Start work on adding support for new filesystems 
Old code tried to create ext2 filesystem from all devices.

Bananymous dd9af56e21 Kernel: Start work on making inodes more thread safe 
All inode operations are now locked and thread blocked

Bananymous c7ec19c25c Kernel: Add basic Credentials for the system 
Now filesystem access/open, etc confirm that you have access for rwxs

Bananymous 7bbdee6cc4 Kernel: Symlinks are now working 
We still have to implement loop or depth detection

Bananymous b048630e5b 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 62fb233eb1 Kernel: DeviceManager is now a 'FileSystem' so it can expose devices 
Shell reads keyboard through /dev/input :)

Bananymous e4bcd98904 Kernel: Add basic mounting to VFS. 2023-03-19 05:51:25 +02:00
Bananymous 1a26a318a4 Kernel: Rework filesystem reading 
We now read from a filesystem to user provided buffer.

Read sizes are determined by read call.

You should now get file descriptors and do reading through Process::current()

Bananymous 1f2ceeb329 Kernel: VFS caches currently open inodes 2023-03-16 15:31:33 +02:00
Bananymous 8940ff8002 Kernel: You don't have to check whether VFS is initialized or not 
VFS now returns Error when attempting to traverse inodes if it did
not find root partition

Bananymous 23b3028e15 Kernel: Rename RefCounted -> RefPtr and implement RefCounted 2023-03-08 03:26:25 +02:00
Bananymous ee5d02aa70 Kernel: Rewrite basically all current disk io stuff 
This is a big commit that was kinda hard to split to smaller ones.

Essentially we now look at all the mass storage devices from PCI
and initialize (P)ATA devices. This doesn't provide any more functionality
but better abstractions and everything doesn't have to be on its old
default port that might be different for modern computers.

Bananymous 5d31e89574 Kernel: Update ErrorOr API and add path find to VFS 
These two are done on the same commit since Changes to Shell were
annoying to make work with only one change

Bananymous 80006ea137 Kernel: Initial work on filesystem 
We support now ext2 directory listing. File reading is not yet supported.
