I'm working on a FPGA vga controller, with an arm cpu (at91rm9200). My FPGA= is plugged on a 16 bits data bus. I'm trying to develop the framebuffer driver, from the epson s1d13xxxfb driver to use my controller. I have a first driver which works well. To accelerate my controller, I would like to read and wri= te in my video memory (controlled by the FPGA) by 8 words bursts. Is it possible = to tell the kernel that the memory must be accessed only by 8 words bursts ?? My driver is available on http://xcsnake.free.fr/driver Thanks a lot Micka=EBl ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
