Bananymous d91a5bccf4 Kernel: Reads return 0 bytes read at the end of device
We used to not have any idea if we where already at the end of device.
Also fixed couple of copy-paste errors from read->write

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 dcee92a6bc 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 5d459130a7 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 62fb233eb1 Kernel: DeviceManager is now a 'FileSystem' so it can expose devices
Shell reads keyboard through /dev/input :)

Bananymous cd0d10b64e LibC: add ENOBUFS errno 2023-03-29 10:58:25 +03:00

Bananymous 16d9d29971 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 a4fb805315 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 fa8e921ee8 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 ea900ad744 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 6a6717cdd3 BAN: ScopeGuard can now be disabled (it wont call the function) 2023-03-28 01:15:13 +03:00

Bananymous e55860eb6b Kernel: Rework processes and VFS so we don't expose inodes
Everything is now done through a file descriptor.

Bananymous 32c3aca52f LibC: add dirent.h 2023-03-25 02:08:33 +02:00
Bananymous 9fd17ef73c LibC: Add stat structure 2023-03-24 18:08:22 +02:00
Bananymous 1fade1aa9e Kernel: Process::working_directory() is now thread safe
I realized you cannot return a stirng view and it to be thread safe

Bananymous 814f0b215d 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 5fd26b4ea8 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 e5eab8bae4 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 75c4f35e85 Kernel: Add possibiliity to create empty files on Ext2
Big rewrite for Ext2 for more easy and optimized code

Bananymous 1be8b2f514 LibC: add more typedefs to sys/types 2023-03-23 19:24:12 +02:00
Bananymous 633414bd20 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
