Bananymous 622007f2ee Shell: Verify that command exists before executing it 
This prevents page fault somewhere when executing non-existing
commands.

Bananymous 3ed25425a3 AOC2023: implement day3 
Solution to second puzzle is not optimal, it definately should be
O(1) space, but I didn't want to think about it.

Bananymous c140dd2a65 Kernel: Fix keyboard layout for underscore 2023-12-01 12:31:16 +02:00
Bananymous dabd79afa7 Userspace: Prepare aoc2023 environment :) 2023-12-01 01:22:53 +02:00
Bananymous 6ccb1bbbf9 init: set default termios on every username prompt 
Before if e.g. Shell crashed init would have broken termios
 2023-12-01 01:22:53 +02:00
Bananymous 9b841cb823 BuildSystem/Kernel: Enable -Wextra and -Werror in kernel 
Only needed to fix some unused variable bugs
 2023-12-01 01:22:53 +02:00
Bananymous c1cac43f28 BuildSystem: Don't build lai with -Wstack-usage 
Lai has two functions that trigger warnings on gcc. There isn't
really anything I can do about it, so just disable the warning
 2023-12-01 01:22:53 +02:00
Bananymous 8564b59e14 image: Remove inheritance from Netbpm 
This inheritance made no sense
 2023-11-29 20:56:05 +02:00
Bananymous fdb6dc94ba Kernel: cast between inheritance with static_cast 
using reinterpret_cast is not a good idea. preferably we would use
dynamic_cast, but that is not possible since kernel is compiled with
-fno-rtti.

Bananymous 327b330338 Kernel: Make internal framebuffer bpp constexpr defined in libc 2023-11-29 20:07:33 +02:00
Bananymous 7090388c70 cp: allow copying all files except directories 
The old condition seemed odd. This allows taking screen shots by
copying the /dev/fb0.
 2023-11-29 16:13:40 +02:00
Bananymous ff550785a7 Userspace: Implement basic image rendering for Netbpm 
You can now render Netbpm (P6) format image to framebuffer using
`image` command. I added basic test image to
/usr/share/images/sample.ppm
 2023-11-29 16:11:35 +02:00
Bananymous d7a3aca5d4 Kernel: Use the correct bpp when writing to framebuffer 2023-11-29 00:31:24 +02:00
Bananymous 056586486d Shell: make clear use \e[2J instead of \e[J 
This makes kernel to actually clear the full screen. If framebuffer
did not fit font exactly last row would be left partially uncleared
 2023-11-28 23:55:37 +02:00
Bananymous 42a1d26d5b Userspace: Implement basic test for framebuffer mmap 2023-11-28 23:52:22 +02:00

Bananymous 60e755210c Kernel/LibC: Implement very basic msync 2023-11-22 22:44:06 +02:00
Bananymous ab9954fe73 Kernel: Delete the now obsolete VesaTerminalDriver 2023-11-22 21:59:11 +02:00
Bananymous fd18071975 Kernel: Implement TerminalDriver for Framebuffer device 
Use this new FramebufferTerminalDriver for terminal instead of the
old VesaTerminalDriver. Only drawback with this is that framebuffer
device can only be intialized after DevFS is initialized.

Bananymous cdf53f33f6 Kernel: Implement basic framebuffer device 
This allows exposing framebuffer to userspace
 2023-11-22 20:34:41 +02:00
Bananymous 25485069e6 Bootloader: Add cache to ext2 inode data block indices 
This reduces the number of read calls with current kernel size from
~1700 to ~700 (60% performance boots). Loading the kernel is now alot
faster.

Bananymous 7a8fd6d04a Kernel: TmpFS doesn't mark any functions as final 
I didn't think these would be overloaded, but they are
 2023-11-21 15:19:34 +02:00
