The following allows building kernel modules for the Hauppauge WinTV DualHD HWC 955D media adapter allowing to use TVheadend natively within the NAS.
It was 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:
$ cat /proc/cpuinfo | grep model.name | head -1
model name : Intel(R) Celeron(R) CPU J3455 @ 1.50GHz
Available patches makes both tuner detected by the kernel using the em28xx.ko updated driver. The lgdt3306a.ko demodulator driver providing the dvb-frontend devices now works and has a few DEBUG messages output. It originally failed because I was also sharing the USB device with a Ubuntu VM running on-top and loading the kernel modules in the wrong order.
Working:
em28xx: both tuners detected & firmware loading OKlgdt3306a: now functional End result:tvheadend: fully detects both tuners
Work is based on the backporting of the following upstream kernel patches:
Demodulator (lgdt3306a):
Adaptor (em28xx):

Along with backported patches from the media-tree that b-rad-NDi made available here:
Using a Ubuntu 18.04 OS VM in order 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
The toolchain & kernel sources are located here: https://sourceforge.net/projects/dsgpl/files/
I use a $HOME/synology directory to drop all the downloaded files and a $HOME/source as my working directory. Later references make usage of theses both paths:
$ mkdir $HOME/synology
$ mkdir $HOME/sources
Download the toolchain from Home / DSM 6.2 Tool Chains / Intel x86 Linux 4.4.59 (Apollolake)
$ wget 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 -O apollolake-gcc493_glibc220_linaro_x86_64-GPL.txz -P $HOME/synology
Download the synology kernel sources from Home / Synology NAS GPL Source / 22259branch / apollolake-source:
$ wget https://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/22259branch/apollolake-source/linux-4.4.x.txz/download -O linux-4.4.x.txz -P $HOME/synology
Extract the files:
- The toolset is decompressed into the
$HOME/synologydirectory - Kernel sources are decompresed in the
$HOME/sourcesdirectory
$ tar -xvf $HOME/synology/apollolake-gcc493_glibc220_linaro_x86_64-GPL.txz -C $HOME/synology
$ tar -xvf $HOME/synology/linux-4.4.x.txz -C $HOME/sources
Download the lgdt3306a and em28xx patches:
$ wget https://raw.githubusercontent.com/th0ma7/synology/master/hauppauge/001-Hauppauge955D-lgdt3306a-v3.patch -P $HOME/sources
$ wget https://raw.githubusercontent.com/th0ma7/synology/master/hauppauge/002-Hauppauge955D-em28xx-Tuner1.patch -P $HOME/sources
$ wget https://raw.githubusercontent.com/th0ma7/synology/master/hauppauge/003-Hauppauge955D-em28xx-Tuner2-v6.patch -P $HOME/sources
We now have to prepare the kernel sources for compilation. Move down to the $HOME/sources directory:
$ cd $HOME/sources/linux-4.4.x
Frist need to copy the apollolake synology kernel configuration
~/sources/linux-4.4.x$ synoconfigs/apollolake .config
Secondly, using a text editor you need to adjust a few variables in the Makefile such as:
EXTRAVERSION = +
ARCH ?= x86_64
CROSS_COMPILE ?= /usr/local/x86_64-pc-linux-gnu/bin/x86_64-pc-linux-gnu-
Lastly, apply the necessary patches:
~/sources/linux-4.4.x$ patch -p1 < ../001-Hauppauge955D-lgdt3306a-v3.patch
~/sources/linux-4.4.x$ patch -p1 < ../002-Hauppauge955D-em28xx-Tuner1.patch
~/sources/linux-4.4.x$ patch -p1 < ../003-Hauppauge955D-em28xx-Tuner2-v6.patch
Modify the original configuration:
~/sources/linux-4.4.x$ sudo make oldconfig
~/sources/linux-4.4.x$ sudo make menuconfig
Device Drivers --->
<M> Multimedia support --->
[*] Media Controller API
[*] V4L2 sub-device userspace API
Everything should now all set for building the modules:
~/sources/linux-4.4.x$ make modules_prepare
~/sources/linux-4.4.x$ make modules M=drivers/media -j4
Using SSH login as admin on the synology NAS:
$ ssh [email protected]
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)
Copy the updated media drivers modules over to the NAS (or download the one from my repository on github - Use at your own risks):
$ sudo scp "[email protected]:~/sources/linux-4.4.x/drivers/media/usb/em28xx/*.ko" .
$ sudo scp "[email protected]:~/sources/linux-4.4.x/drivers/media/dvb-frontends/lgdt3306a.ko" .
$ sudo scp "[email protected]:~/sources/linux-4.4.x/drivers/media/dvb-frontends/media.ko" .
Copy the load/unload script to the NAS as well (and make it executable):
$ wget https://raw.githubusercontent.com/th0ma7/synology/master/hauppauge/hauppauge-load.sh
$ wget https://raw.githubusercontent.com/th0ma7/synology/master/hauppauge/hauppauge-unload.sh
$ chmod 755 hauppauge-*.sh
Create a local rc file locate at /usr/local/etc/rc.d/hauppauge.sh that will be executed at boot time (or copy hauppauge-load.sh script):
#!/bin/sh
# Load mandatory modules
sudo insmod /lib/modules/dvb-core.ko
sudo insmod /lib/modules/rc-core.ko
sudo insmod /lib/modules/dvb-usb.ko
sudo insmod /lib/modules/videodev.ko
sudo insmod /lib/modules/v4l2-common.ko
sudo insmod /lib/modules/tveeprom.ko
# Load Hauppauge updated drivers
sudo insmod /lib/modules/si2157.ko
sudo insmod /usr/local/lib/modules/$(uname -r)/media.ko
sudo insmod /usr/local/lib/modules/$(uname -r)/lgdt3306a.ko
sudo insmod /usr/local/lib/modules/$(uname -r)/em28xx.ko
sudo insmod /usr/local/lib/modules/$(uname -r)/em28xx-dvb.ko
Execute manually the rc script to confirm all is ok:
$ sudo /usr/local/etc/rc.d/hauppauge.sh
Normally should see the following in kernel dmesg (added a few DEBUG to lgdt3306a):

Now reboot the NAS using the admin web page and confirm after reboot that the dmesg output and lsusb are still ok.
In case you run into issue where your NAS refuses to fully shutdown (and thus reboot) with the power button led blinking, it is most probably due to tainted modules still in memory. Using the hauppauge-unload.sh script prior to shutdown/reboot will remove all the tainted modules from memory thus allowing the NAS to properly shutdown/reboot.
