Bananymous 1f2ceeb329 Kernel: VFS caches currently open inodes 2023-03-16 15:31:33 +02:00
Bananymous c012822d49 BAN: Rename StringView suffix from _sv to sv 2023-03-16 12:15:16 +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 fc58baf54d Kernel: if VFS initialization does not find root, we fail 2023-03-09 02:17:42 +02:00
Bananymous 7458f68c38 BAN: Error can now be constructed from c_string or format string 
If the resulting string would overflow, we just truncate it to fit
the error message buffer (128) bytes

Bananymous 90a7268e5a BAN: Rewrite RefCounted to return ErrorOr 2023-03-02 12:30:11 +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
