Hi, My application reads 1 line of spectometer data from the parallel port every 40.8ms. Each line contains about 12kb of data, and a full image is made up of upto 3200 lines, or about 38mb of data per image. Problem is that since fifos are limited to 128kb I must transfer each line as it comes in which seems excessive. Does anyone have any suggestions? Can the kmalloc in rtl_fifos be changed to use vmalloc which would alleviate the problem?
