Subject: mmap dma address
Date: Fri, 1 May 2009 10:03:41 -0500	[thread overview]
Message-ID: <bb6204720905010803u1f9a3bc3g121d044c279b79e9@mail.gmail.com> (raw)

Could someone tell me how to mmap a dma buffer allocated with
dma_alloc_coherent?  I have found some patches that Takashi Iwai
submitted to create a dma_mmap_coherent function but it doesn't look
like its been accepted upstream, is there a reason why?  Is there a
better way for mmaping a dma address?  I am trying to get mmaping
working on a mpc5121e i2s audio driver so that I can do alsa audio
mixing.

Thanks,
Gabe
