Converting kdrive server to Xorg driver

[Graeme Gregory]

Hi, I have been trying to convert a kdrive server for the freerunner
phone into an Xorg driver and I have one small question that I can't
seem to answer myself from TFM.

This is on an arm device if that makes any difference.

Is the following code in kdrive

reg_base = (char *)KdMapDevice(0x8000000, 0x2400);
KdSetMappedMode(0x8000000, 0x2400, KD_MAPPED_MODE_REGISTERS);

equivalent to this code in Xorg?

reg_base = xf86MapVidMem(pScreen->myNum, VIDMEM_MMIO, 0x8000000, 0x2400);

Thanks

Graeme
