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 f8f7e2208f BuildSystem: Remove old bootloader target 
And creating image now builds the bootloader
 2023-11-20 00:56:06 +02:00
Bananymous 8630f71f0c Toolchain: Build full toolchain with one call to toolchain/build.sh 2023-11-20 00:56:06 +02:00
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 cd646a1ab7 Bootloader do some directory restructuring 2023-11-18 13:59:45 +02:00
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 95af728e39 Kernel: Don't calculate divisor in a for loop in ext2 inodes 2023-11-17 19:02:01 +02:00
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.

Bananymous 84040e64b8 Kernel: Don't use multiboot2 explicitly. Parse it to common structure

Bananymous 9d4101e0c5 Bootloader: Implement basic ext2 filesystem 
This can search for files in an ext2 filesystem. Only 12 blocks
are currently supported.

Now only ELF loading is missing for loading the actual kernel!

Bananymous bd3f2bb61c Bootloader: Split bootloader into multiple files

Bananymous 7ca9a961b3 Bootloader move bootloader code from arch directory 
The os itself only supports x86 so this won't matter. x86_64 and i386
use the same bootloader assembly.
