Subject: [PATCH RFC 0/2] net: macb: Fixing DMA usage
Date: Fri, 21 Feb 2014 11:30:23 -0800 [thread overview]
Message-ID: <1393011025-18537-1-git-send-email-soren.brinkmann@xilinx.com> (raw)
Hi,
when I enabled CONFIG_DMA_API_DEBUG recently, I started seeing warnings
caused by the macb's DMA usage.
I read trough Documentation/DMA-API_HOWTO.txt and tried solving these to
the best of my knowledge of the networking and DMA systems. But that
knowledge is not very deep. So, there might be fundamental flaws with
these patches, hence as RFC only.
Thanks,
Sören
