Subject: DMA to static address
Date: Fri, 28 May 2010 16:43:41 +1000 [thread overview]
Message-ID: <1275029021.4690.83.camel@Ubuntu-Desktop> (raw)
Hi,
I've been looking around in the kernel source and googling, and I'm
having trouble finding any information about doing a DMA transfer with
an I/O device that implements a single address for DMA. I.e. the
external memory address should not be auto incremented during the
transfer.
Is that mode supported by the Linux generic DMA system, and where should
I look?
Specifically this is for the i.MX27 and friends.
Regards,
James.
