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

8564b59e14 image: Remove inheritance from Netbpm 
This inheritance made no sense
 2023-11-29 20:56:05 +02:00

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.

7090388c70 cp: allow copying all files except directories 
The old condition seemed odd. This allows taking screen shots by
copying the /dev/fb0.

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

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

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.

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.

9e44e8be75 Buildsystem: default bootloader is not my custom one 
You can set BANAN_BOOTLOADER=GRUB to use grub instead. Image creation
does not convert disk image now automatically between bootloaders and
calling ./bos image-full is now required.

c9e9cfd361 Bootloader: Implement VESA video mode query and pass it to kernel 
Kernel now gets framebuffer from bootloader. Framebuffer dimensions
and bpp are hardcoded in bootloader, but will probably be read from
