A new enhanced bootsplash
Testing this bootsplash
1. build kernel
2. install the kernel
3. add a theme for testing
4. replace /etc/rc
5. replace /boot/defaults/loader.conf
5. run bsplash-fix-grub-cfg (only for GRUB users)
6. reboot and enjoy bootsplash
Project description
I propose a new bootsplash mechanism. Currently, we can enable bootsplash by adding few options such as splash_bmp_load to /boot/loader.conf but it only displays an image file so I cannot reassure that the system works well. Therefore, I want to develop a new bootsplash mechanism which enables enhancements of attractiveness, such as progress bar. I think this will greatly improve user experience. I’m planning to implement this using src/sys/dev/fb, SYSINIT and kernel module system.
Approach to solving the problem
kernel
A bootsplash system follows configurations in /boot/splash/foo/loader.conf like this:
1 bsplash_image_name="/boot/splash/foo/image.bmp"
2 bsplash_image_load="YES"
3
4 bsplash_background_y_origin="0"
5
6 bsplash_progress_bar_y_origin="800"
7 bsplash_progress_bar_height="30"
8 bsplash_progress_bar_width="500"
9
10 bsplash_animation_y_origin="1100"
11 bsplash_animation_height="300"
12 bsplash_animation_width="300"
13 bsplash_animation_repeat="YES"
userland utilities
bsplash-create loads theme.conf and generates configuration for /boot/loader.conf and generates an image just like CSS sprites.
bsplash-install copies files generated by bsplash-create into /boot/splash.
bsplash-change overwrites bsplash configuration in /boot/loader.conf with /boot/splash/theme-name/loader.conf.

Test Plan
#1
Write code in VM on VirtualBox
make and copy generated kernel and modules to /boot
- Launch .vdi of the VM with QEMU on host OS
- Check output and dmesg
#2
make buildinstall on a real machine.
- boot it
- check output and dmesg
