[Linaro-uefi] [linaro-uefi] How to implement GOP frame buffer

Hi Ard,

To support UEFI GOP frame buffer, is it enough to provide UEFI GOP protocol and valid FrameBufferBase and FrameBufferSize via GOP mode?

I still have some question. As we are using a PCIe VGA device, the frame buffer might probably be certain PCIe memory resource BAR of VGA device. Then is it possible for OS to re-enumerate PCIe bus and re-allocate memory BAR resources? If so, who will be responsible to update frame buffer base?

Thanks and regards,

Heyi Guo (Gary)
