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 4ba3a17af3 Kernel: Add more APIs to FramebufferDevice 2023-11-22 21:56:27 +02:00
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

Bananymous f2397b775c BuildSystem: Remove old bootloader target 
And creating image now builds the bootloader

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 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

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!
