I would like to know if the i915 driver supports all the features of DirectFB. I don't know whether this is the right way to ask what I have in my mind. When I look at the code, I find that it support just 'fill rectangle' and 'image blitting'. Is that all or does it support more? Please guide me.
If you're looking at the code, and finding support only for 'fill rectangle' and 'image blitting', then that's probably all that's supported. If you need help analysing the code, try asking one of the DirectFB mailing lists.
