Hauppauge WinTV DualHD HWC 955D

The following allows building kernel modules for the Hauppauge WinTV DualHD HWC 955D media adapter allowing to use TVheadEnd (TVH) natively within the NAS.

https://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-955Q

In theory this procedure is also valid to build most supported DVB adaptors available from the Media Tree within the Linux Media Subsystem.

Tested on the following hardware:

model: DS918+
OS: DSM 6.2.2 build #24922
kernel: 4.4.59+
arch: x86_64
core name: Apollo Lake

Finding your running kernel:

$ uname -mvr
4.4.59+ #24922 SMP PREEMPT Thu Mar 28 11:07:03 CST 2019 x86_64

Finding your CPU type:

https://en.wikichip.org/wiki/intel/celeron/j3455

$ cat /proc/cpuinfo | grep model.name | head -1
model name	: Intel(R) Celeron(R) CPU J3455 @ 1.50GHz

Current status

I had backported patches to the Synology DSM 6.x 4.4.59+ kernel but there where a few pending issues. Since then b-rad-NDi ended-up providing a backporting tool that allows rebuilding the media tree over the Synology DSM kernel. This solution as been playing really nicely on my NAS over the last months. Big thanks to b-rad-NDi!!!
For more details on b-rad-NDi project refer to:

https://github.com/b-rad-NDi/Embedded-MediaDrivers

Working:

em28xx: both tuners detected & firmware loading OK
lgdt3306a: fully functional

End result:

tvheadend: fully detects both tuners

Instead of building your own I’ve made available a pre-built module package for Hauppauge 955D USB DVB dongle to work on Synology NAS 6.2.2 kernel 4.4.59+ with Apollolake CPU (e.g. DS918+):

Preparation

Using a Ubuntu 18.04 OS to build the updated modules install a few essential packages:

$ sudo apt update
$ sudo apt install build-essential ncurses-dev bc libssl-dev libc6-i386 curl libproc-processtable-perl

Clone b-rad-NDi git repository:

$ git clone https://github.com/b-rad-NDi/Embedded-MediaDrivers.git
$ cd Embedded-MediaDrivers
~/Embedded-MediaDrivers$

Create a SYNO-Apollolake download directory:

$ mkdir dl/SYNO-Apollolake

Download the toolchain

https://sourceforge.net/projects/dsgpl/files/DSM%206.2%20Tool%20Chains/

$ wget --content-disposition https://sourceforge.net/projects/dsgpl/files/DSM%206.2%20Tool%20Chains/Intel%20x86%20Linux%204.4.59%20%28Apollolake%29/apollolake-gcc493_glibc220_linaro_x86_64-GPL.txz/download -P dl/SYNO-Apollolake/

Download the Synology DSM kernel sources:

https://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/22259branch/

$ wget --content-disposition https://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/22259branch/apollolake-source/linux-4.4.x.txz/download -P dl/SYNO-Apollolake/

Initialize the repository:

$ ./md_builder.sh -i -d SYNO-Apollolake

Build a default Synology DSM kernel build (takes a while):

$ export MAKEOPTS="-j`nproc`"
$ ./md_builder.sh -B media -d SYNO-Apollolake

Configure the media tree, get the latest media tree patches that applies over the default Synology DSM kernel and build the media drivers:

$ ./md_builder.sh -g -d SYNO-Apollolake
$ cd build/SYNOAPOLLOLAKE/media_build
build/SYNOAPOLLOLAKE/media_build$ ./build

Installation

Using SSH login as admin on the synology NAS:

$ ssh admin@<my.syno.nas.ip>

Create a new local module directory (name will match kernel version):

$ sudo mkdir -p /usr/local/lib/modules/$(uname -r)
$ cd /usr/local/lib/modules/$(uname -r)

Download the updated media drivers modules over to the NAS (the following downloads not only the mandatory modules for Hauppauge WinTV but rather all the media tree modules):

$ cd /usr/local/lib/modules/$(uname -r)
$ sudo scp "username@<my.ubuntu.linux.ip>:~/Embedded-MediaDrivers/build/SYNOAPOLLOLAKE/media_build/v4l/*.ko" .

Copy the start/stop/load/reset script to the NAS (and make it executable):

$ cd /usr/local/lib/modules/$(uname -r)
$ wget https://raw.githubusercontent.com/th0ma7/synology/master/hauppauge.sh
$ chmod 755 hauppauge.sh

Create a symbolic link to /opt/bin/hauppauge.sh for ease of use:

$ sudo ln -s -T -f /usr/local/lib/modules/$(uname -r)/hauppauge.sh /opt/bin/hauppauge.sh

Create a local rc file locate at /usr/local/etc/rc.d/media.sh that will be executed at boot time:

$ cat << EOF | sudo tee /usr/local/etc/rc.d/media.sh
#!/bin/sh
/usr/local/lib/modules/$(uname -r)/hauppauge.sh load
EOF
$ sudo chmod 755 /usr/local/etc/rc.d/media.sh

Execute manually the rc script to confirm there is no error:

$ sudo /usr/local/etc/rc.d/media.sh

Validate the status:

$ sudo /opt/bin/hauppauge.sh status

Normally should see something similar in kernel dmesg:
