Bananymous f2397b775c BuildSystem: Remove old bootloader target 
And creating image now builds the bootloader
 2023-11-20 00:56:06 +02:00
Bananymous 8b81406b81 Toolchain: Build full toolchain with one call to toolchain/build.sh 2023-11-20 00:56:06 +02:00
Bananymous e2515c1109 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 5293ae070d 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 6e2443ca72 Bootloader do some directory restructuring 2023-11-18 13:59:45 +02:00
Bananymous a312d75bb2 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 a554bd0fd8 Bootloader: Fix kernel memset to zero 2023-11-17 21:05:02 +02:00
Bananymous f0d2a211ea Bootloader add temporary initial command line 
This will probably be read from some config file at some point

Bananymous 065eec430e Kernel/Bootloader: banan-os can now be booted with my bootloader :D 2023-11-17 20:33:02 +02:00
Bananymous 5f4d81a502 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
 2023-11-17 20:31:42 +02:00
Bananymous 41065d2f9a Kernel: Don't calculate divisor in a for loop in ext2 inodes 2023-11-17 19:02:01 +02:00
Bananymous 3daf3d53a3 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 ec56e9c6f1 Kernel: Don't use multiboot2 explicitly. Parse it to common structure 
This allows support of multiple different bootloaders

Bananymous a9412aa741 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 8aab3a62cc Bootloader: Build with cmake instead of custom script 2023-11-14 03:44:47 +02:00
Bananymous b0b39c56ba Bootloader: Split bootloader into multiple files 
This cleans up the code since bootloader is starting to near 1k lines
 2023-11-14 03:27:52 +02:00
Bananymous 055b1a2a1a 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.

Bananymous a3a287f5ca Bootloader: Continue work on bootloader 
Bootloader can now get the memory map and read cmdline from user.

Now 'just' video mode query, ext2 and ELF parsing are needed :D

Bananymous c47f6a78bc Bootloader: Start work on bootloader 
I wrote a fast first stage bootloader and a installer to put it into
a disk image.

Bananymous cec04a2858 Kernel: Remove now obsolete RamFS 
Everything is using now the better TmpFS which uses physical pages
