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?

Thanks in advance,

Dan Peters
