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

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 c7286396d8 Kernel: Move ACPI to its own file 2023-03-27 17:30:45 +03:00
Bananymous 0cebf248a3 BAN: move placement new declaration to Move.h 2023-03-27 03:38:06 +03:00

Bananymous 666051fd34 Kernel/BAN: move unix time conversion to BAN and add stat to Shell 2023-03-27 00:49:58 +03:00
Bananymous e55860eb6b Kernel: Rework processes and VFS so we don't expose inodes 
Everything is now done through a file descriptor.

Bananymous 1fade1aa9e 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 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 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
 2023-03-23 18:52:58 +02:00
Bananymous 7ca6cd61be Kernel: Move get_unix_time to RTC namespace 2023-03-23 18:14:51 +02:00

Bananymous 4ffc69a6e4 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
 2023-03-22 02:09:22 +02:00
Bananymous 61ac9833be Kernel: Reading from fd verifies that file is opened for reading 2023-03-22 01:55:58 +02:00
Bananymous dbf7d9f19e 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 a6e5a0b704 Kernel: cksum uses now a different crc32_table to match linux 'cksum' 2023-03-22 01:55:21 +02:00

Bananymous 54824aec74 Kernel: Cleanup font parsing 
We use now the LittleEndian<> wrapper for PSF2 header and no more
magic constants in code

Bananymous f9ae1f0023 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
