Hi I have a custom board which is essentially an icecube with an FPGA on the local bus. I have a driver which pulls data from the FPGA in response to interrupts using memcpy_fromio(). I would like to reduce the CPU usage.
Has anyone used bestcomm to move data from LPB to memory? Is there an example anywhere? From the app note AN2604 it looks like writing a bestcomm task is difficult at best. Perhaps it is possible to re-use the ethernet rx task for this purpose? I'm using mainline 2.6.16.18 with Sylvain's patches for ethernet/bestcomm/ide. (BTW, will that code make it into the mainline any time soon?) Thanks in advance for any advice -roger __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
