Hi, I’ve used sdl1.2 for quite a few packages in the widely used (maybe 6 people) openwrt-zipit linux distribution because of the /dev/fb support. If a /dev/fb backend was available for sdl2 I’d be able to move forward and use that. Going through DirectFB adds one layer too many for a small device with just a framebuffer and limited RAM.
You can get some idea what I mean by “small device” here. http://macrofig.blogspot.com/
