Hi, I am new to FPGA use and seeking helpful advices.
Here is what I need on Linux:
Application needs to use the following interface to communicate with FPGA on PCIe:
fpga_processing(int fpga_channel, char *input_buf, int input_size, char *out_buf, int *output_size);
* fpga_channel: specify which fpga to use ( assuming there are multiple on board )
* input_buf stores raw data ( of size input_size) to be passed to FPGA
* FPGA stores processed data at output_buf, and returns its size to output_size
My question: are there any Linux DMA drivers ( preferably open source ones ) to accomplish this?
Thanks in advance for any info.
