Hi, everyone
I am Seiya Nuta, a university student in Japan and I=92m going to submit =
a GSoC proposal.
I want to develop a new bootsplash mechanism to add animation such as =
progress bar.
It eases concern whether it works on boot and enhances the =
attractiveness of FreeBSD
to desktop users.
I=92m willing to work on this even if my proposal is not accepted so I =
would like you to tell
me your frank opinion about my proposal.
My proposal is as follows:
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. I worry whether it works well on boot so I assume we need a new =
bootsplash which can
display animation: progress bar, loading circle ball. Themes are kernel =
modules and draw
images in two ways: direct drawing and layered drawing. Direct drawing =
is same as
splash_bmp; only draw an image. Layered drawing is a new way; stack =
images and text. It
also enables technique like CSS sprite.
Deliverables:
- Implementation of bootsplash direct drawing / layered drawing
- Makefile and scripts for creating bootsplash themes
- Example themes
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
Schedule:
Work Period #1
- (May 19 - May 25) implement direct drawing
- (May 26 - June 8) add changes to src/sys
- (June 9 - June 15) write Makefile and scripts for creating themes
- (June 16 - June 22) create and enjoy a flip book in bootsplash =
using direct drawing
Work Period #2
- (June 23 - June 29) print characters in a framebuffer
- (June 30 - July 20) implement layered drawing
- (July 21 - July 27) support layered drawing in scripts for =
creating themes
- (July 28 - 'pencils down' date) create themes
Regards,
Seiya Nuta
