Subject: 8 words bursts for fbdev driver
Date: Mon, 28 May 2007 17:25:59 +0200	[thread overview]
Message-ID: <1180365959.465af4876a6a8@imp.free.fr> (raw)

Hello,

I have posted this message on the linux-kernel mailing list, but I think it
could be more appropriate here.
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

Thanks a lot

Mickaël
