OMAP3 & DSP

OMAP3 & DSP

[Sven Brandau]

Hello,

is there any driver support for the DSP on OMAP3 SOCs available in the 
current kernel?

This means DSP image loading, starting and communication mechanisms 
between ARM CPU and DSP.

The original TI driver only running on kernels with versions 2.6.x.

Best regards,
Sven

Last time I looked for, I could not find any.
However, with only small patches, the dvsdk for dm3730 for instance
runs fine on 3.10 kernel.
I did not try on later kernel.

On the other hand, the dspbridge driver that was supposed to be the
way forward is now marked as BROKEN...

we still try to support out-of-the-tree tidspbridge, last version I 
tried and it was working was 3.16 (iirc), check it if it does the job 
for you:

https://gitorious.org/linux-n900/linux-n900/source/4af08adb31709cb3e057af10675f354553848653:drivers/staging/tidspbridge

It is tailored to be compatible with Maemo 5, but should work (in 
theory) with any distro as long as you have gst-dsp.
