Hi all, I'm a hw/fw designer and I'm now involved in developing a simple QVGA controller inside a FPGA for an ambedded architecture (using PPC8270 micro and a sharp TFT 6bit/color display). I found on opencores a VGA IP core that seems to be interesting and usable but it doesn't manage OVERLAY.
I do not know how Linux manage X window sys... I google a lot whithout find an useful answer, so please help:
- Do I need to implement an OVERLAY MANAGEMENT feature inside my FPGA or not? Could I charge Linux's for OVERLAY features ?
- Should I write overlay features inside the driver or it's already implemented in kernel?
- Where I could find info about video driver developing and kernel integration?
- Do you have suggestion ?
Any help will be appreciated! Thanks in advance, regards!
