Getting a patched driver?

English Hardware

What is the easiest way to get this driver into OpenSUSe 42.1?

Hi
The easiest way would be to add kernel:stable which is at 4.8.1, else use the 4.8.1 source and build in tree, or create a KMP? I would guess those commits missed 4.4?

Just tested it with sources from 4.8.1 and it compiled for 4.1.X without adding
extra patches, you need

dvbdev.h

and

dvb_frontend.h

from drivers/media/dvb-core

and

mn88473.c

mn88473.h

mn88473_priv.h

from media/dvb-frontends

plus a very simple Makefile like this one

Makefile for the kernel DVB frontend device driver mn88473.

obj-m += mn88473.o

all in the same directory,

make -C /lib/modules/$(uname -r)/build M=$(pwd) clean modules

make: Entering directory /usr/src/linux-4.1.33-1.gdd1494b-obj/i386/pae' LD /tmp/mn88473-4.8.1/built-in.o CC [M] /tmp/mn88473-4.8.1/mn88473.o Building modules, stage 2. MODPOST 1 modules CC /tmp/mn88473-4.8.1/mn88473.mod.o LD [M] /tmp/mn88473-4.8.1/mn88473.ko make: Leaving directory /usr/src/linux-4.1.33-1.gdd1494b-obj/i386/pae’

Works for me™

Yup, looks like it was added in 4.5.

Added “mn88473” kmp packages (plus a firmware package which is mandatory for
this driver) for openSUSE 13.1,13.2 and 42.1:

If it still does not work, don’t blame me and report bugs/problems upstream.

Well I am running:

tvburk:~ # uname -a
Linux tvburk 4.1.15-8-default #1 SMP PREEMPT Wed Jan 20 16:41:00 UTC
2016 (0e3b3ab) x86_64 x86_64 x86_64 GNU/Linux

As the box will not even boot with the later kernel… Just hangs.

You could also have installed the latest set of v4l-dvb drivers by using the media build (see the v4l-dvb wiki on linuxtv for details)
