Hi Deepali, I tried merging the DSPLINK 1.6x into 2.6.10 kernel. But some of the mutex functions and files are not present in the 2.6.10 kernel. (Attached file gives the compilation errors, when I try to build the DSPLINK 1.6x w.r.t 2.6.10 kernel)
But in the TI E2E mails, Mugdha has mentioned that few changes in the OSAL files of DSPLINK 1.6x could make the DSPLINK work with 2.6.10 kernel with RT mode. (Link - http://e2e.ti.com/forums/t/2833.aspx) 1) Do I need to add few patches to 2.6.10 kernel, to make DSPLINK 1.6x compatible with 2.6.10? 2) Can you please tell me what all changes needs to be done in DSPLINK 1.6x for making it compatible with 2.6.10 kernel? Thank you.

Support for RT mode was added in DSPLink 1.6x, and in this version, MVL Pro 4 support was removed. One thing that the you could try is to merge support for 2.6.10 kernel into DSPLink 1.6x.

And I am looking for a DSPLINK which can work with 2.6.10 kernel(with PREEMPT_RT enabled) with MVL pro 4. Has anybody tried using/building DSPLINK on 2.6.10 kernel with PREEMPT_RT mode enabled? Please let me know. Regards, Santosh
