Implement framebuffer host GUI for ChrysaLisp #272

Closed ghaerr closed 1 year ago

ghaerr commented 1 year ago

This PR will be updated following the work-in-progress of getting CL running on Raspberry PI framebuffer.

This replaces the preview draft version previously submitted in #270, and builds a (somewhat) working version of CL by running make GUI=fb on a Linux system with framebuffer support. It has currently only been tested on RPi 3. To run the framebuffer version, the ./run.sh script doesn't work well, since stdin is closed by the shell script executing the system in the background. Instead, run obj/arm/ARM64/Linux/main_gui obj/arm64/ARM64/sys/boot_image -run gui/gui/gui.lisp. (Yes, all of that is required!)

The mouse and keyboard are working, but graphics text output is still a bit funky due to lack of proper alpha blending support and a back buffer (coming soon). There's still lots to do on this, but I thought to post it in case others might want to play around with it a bit.

After more implementation and much more testing, the plan would be to merge this PR to support CL framebuffer.

Here's a screenshot of the system after the login screen: IMG_4802D

For some reason, keyboard input isn't working in the Terminal app, but it does work in Login.

To exit the system, type ESC.

The framebuffer host GUI for CL is working well with all features present. It probably ought to be tested a bit on various PI systems. The framebuffer format should be set for 32bpp ARGB.

CL FB 6

host_gui_set_color color premul done, single alloc for textures, control characters and scroll wheel working.

No known problems.
