Bananymous 52309413af Shell: Verify that command exists before executing it 
This prevents page fault somewhere when executing non-existing
commands.

Bananymous b0ac571abe 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 f1c2284512 Kernel: Fix keyboard layout for underscore 2023-12-01 12:31:16 +02:00
Bananymous 2188dc2e1c Userspace: Prepare aoc2023 environment :) 2023-12-01 01:22:53 +02:00
Bananymous ff83c52c89 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 1cfab4ae04 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 2ac28cba6e 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

Bananymous 547aeb0170 image: Remove inheritance from Netbpm 
This inheritance made no sense
 2023-11-29 20:56:05 +02:00
Bananymous ebe465e81e 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 c10dffd719 Kernel: Make internal framebuffer bpp constexpr defined in libc 2023-11-29 20:07:33 +02:00
Bananymous 21392e34cb cp: allow copying all files except directories 
The old condition seemed odd. This allows taking screen shots by
copying the /dev/fb0.

Bananymous ea4a45aef2 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 45d8d76e87 Kernel: Use the correct bpp when writing to framebuffer 2023-11-29 00:31:24 +02:00
Bananymous e3890fa7c4 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 eeadf5fff1 Userspace: Implement basic test for framebuffer mmap 2023-11-28 23:52:22 +02:00

Bananymous 0adb28e23f Kernel: Delete the now obsolete VesaTerminalDriver 2023-11-22 21:59:11 +02:00
Bananymous d4aa33b18b 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 e9d762892c Kernel: Implement basic framebuffer device 
This allows exposing framebuffer to userspace
 2023-11-22 20:34:41 +02:00
Bananymous d98782a10c 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 b437d4eb41 Kernel: TmpFS doesn't mark any functions as final 
I didn't think these would be overloaded, but they are
