| |
Hello,
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 write 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
