Re: Help - trying to get multiproto TT03200 driver working via old API

Hmm,

Looking at this further. I think the patch will break compatibility with all the old non multi-protocol drivers. That is the last thing I want to do. What is needed is something that converts to the new api only when needed. I wonder if there is a simple test to see if the underlying driver is old or new.

I am somewhat out of my depth here!

I am beginning to think I should have bought a DVB-S card after all. Especially as none of the services I want to view are S2!

Thanks,

Looking at the patch diff is does not appear too complex. I will try and see if I can work out a minimal patch against the current tree. If not I will fall back on your suggestion. I think it would be desireable if what makes it into the kernel supports new cards been driven in the old way.

I feel your pain, patch-hell isn't a fun place to be :)

Lots of people make guides on how to fix something, unfortunately they forget that trees grow, and a patch that works today probably won't work tomorrow.
Thankfully you can check out different revisions!

I'd sugest you try this patch out on manu's original multiproto tree, revision number 7213 (that was the last update, in april, before she made her patch)

hg clone -r 7213 http://jusst.de/hg/multiproto

I am have been trying to get gnutv to drive the TT-3200 driver using the old api (gnutv uses dvb-apps/lib which is not patched for multi proto). After much head scratching I realised that the fialure of the driver to get lock when exercised in this way seemed to be related to DVBFE_ALGO_SEARCH_AGAIN not being set when the FE_SET_FRONTEND ioctl path was followed rather than than the DVBFE_SET_PARAMS path. A search of the list revealed that Anssi Hannula had already worked this out and made a patch (http://www.spinics.net/lists/linux-dvb/msg26174.html). However it does not look like this patch has made it into the code that Manu has asked to be merged into the kernel. Does this mean that the merged code will not be compatible with applications such as gnutv which use dvb-apps/lib or other apps which use the old api?

To help me carry on with my testing. Is there as version of Anssi's patch that can be applied against a recent clone of Manu's code.

I apologise if this has been visited before; but I am finding it virtually impossible to unravel the complexities of what patch matches what tree.

Help
