Bananymous dfe5a2d665 All: Cleanup all files 
Add newline to end of files and remove whitespace from end of lines
 2024-01-24 15:53:38 +02:00
Bananymous 9fa13079f2 Kernel: Implement supplementary groups 
This code has very ugly file parsing code. I have to create API
for reading files line by line in kernel space...

This allows users to open framebuffer/input files without root.

Mounting has to be moved to userspace soon. It makes no sense to
hard code permissions for every (device) file.

Bananymous cdf53f33f6 Kernel: Implement basic framebuffer device 
This allows exposing framebuffer to userspace
 2023-11-22 20:34:41 +02:00
Bananymous 5044810451 Kernel: Make DevFS use the new and better TmpFS instead of RamFS 2023-11-07 16:05:05 +02:00
Bananymous f3d9da9549 Kernel: Rewrite all read/write functions to use BAN::ByteSpan 
This allows us to not work with raw pointers and use sized containers
for reading and writing.

Bananymous 2301654c4e Kernel: Rework RamInode API 
RamInode is now a general RamInode with no data. RamFileInode is now
a inode for regular files. This is much cleaner and more intuitive
since there is no reason for most non-regular inodes to hold data
Vector.

Bananymous 921d95d18f All: Clear lines with only whitspace in them 2023-09-10 00:31:42 +03:00
Bananymous 1fcf122c50 Kernel: Add basic ZeroDevice to /dev/zero 2023-09-10 00:31:42 +03:00
Bananymous 323de3c866 Kernel: Rework whole Terminal structure 
Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.
