Bananymous 6ccb1bbbf9 init: set default termios on every username prompt
Before if e.g. Shell crashed init would have broken termios

Bananymous 9b841cb823 BuildSystem/Kernel: Enable -Wextra and -Werror in kernel

Bananymous 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

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

Bananymous 327b330338 Kernel: Make internal framebuffer bpp constexpr defined in libc 2023-11-29 20:07:33 +02:00
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 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

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.
