RE: CMEM/DSPLink and 2.6.28 kernel?
The wiki page below has been updated with patches/changes required (over DSPLink 1.6x) for building with 2.6.28 kernel http://tiexpressdsp.com/wiki/index.php?title=Building_DSPLink_with_kbuild Regards, Mugdha -Original Message- From: davinci-linux-open-source-boun...@linux.davincidsp.com [mailto:davinci-linux-open-source-boun...@linux.davincidsp.com] On Behalf Of Tivy, Robert Sent: Friday, January 30, 2009 4:02 AM To: Yusuf Caglar AKYUZ; Ryan Talbot Cc: davinci-linux-open-source@linux.davincidsp.com Subject: RE: CMEM/DSPLink and 2.6.28 kernel?
