Support for CTX1924_V2 PCIe DVB-S2 card, NXP SAA7231 chipset

ximxxomd · May 15, 2019 at 11:44 PM

There seems to be a driver for the SAA7231 chipset. I found it here: add saa7231 driver · stsp/BeholdT8@e85a3f0 · GitHub

Here some more information about the hardware: Re: saa7231 is anybody trying · winysrj/linux-media@072daef · GitHub

I also cant find anything about that hardware here: https://bitbucket.org/crazycat/linux_media/src/latest/

This driver does not seem to be mainlined. Does someone know why? Can someone mainline the driver to the linux kernel or at least put it into libreelec or crazycat (that is been used by libreelec) code?

Sorry at first for moderators for digging arch topics. I see that is obsolete thread. If you recommend creating new one I'il do.

I have working frontend for saa7231 that tune into dvb-s/s2. Yet I need some clarifications regarding those card.

You, exactly you! You can help! Provide similar output, at first it'll be enough

If you have questions, ask questions. Otherwise you just made a statement that has no answer.
