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

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

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

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 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 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.

Bananymous cadb56d8ba Kernel: ProcFS inodes reflect processes ruid/rgid 
setgid/setuid did not change the permissions of procfs inodes. This
made Shell launched by init not appear in meminfo.

Bananymous 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
config file at some point.

Bananymous d1444761a3 Bootloader: Clear screen, better memcpy 
Clear screen before jumping to kernel. Memcpy now uses ebx as offset
register, so only one register has to updated every loop

Bananymous 24d87acec4 Kernel: Serial now uses random size for some serial ports 
If the serial port doesn't repond with a size, just use a random
one. There is no reason to ditch the whole output if you cannot
determine its size.
