Experimental LinuxTV x86_64 build 20210113~f6e3542-1 for DSM-6.2.3

th0ma7 commented 3 years ago

Placeholder for comments related to success on loading modules and making a DVB device to work on your Synology NAS.

Experimental LinuxTV packages for Synology 6.2.3 x86_64 archs available at:

https://github.com/th0ma7/synology/tree/master/packages/linuxtv

It currently only loads high level modules:

rc/rc-core.ko
mc/mc.ko
v4l2-core/videodev.ko
common/tveeprom.ko
common/videobuf2/videobuf2-common.ko
common/videobuf2/videobuf2-v4l2.ko
common/videobuf2/videobuf2-memops.ko
common/videobuf2/videobuf2-vmalloc.ko
dvb-core/dvb-core.ko

The default start_stop calls my generic script located at /var/packages/linuxtv/target/bin/linuxtv.sh Modules are located at /var/packages/linuxtv/target/lib/modules Firmware are located under /var/packages/linuxtv/target/lib/firmware

In order to get your device working you will need to manually insmod the relevant modules in the right order and follow-up the dmesg output. It isn't that trivial but it should normally work.

For instance, Hauppauge WinTV would require the following modules to be loaded manually:

em28xx_dvb
em28xx
lgdt3306a
si2157

IMPORTANT NOTE: This is highly experimental at this stage, upon loading a module you might experience a NAS reboot (was hapening when trying to load DSM-6.1 modules against DSM-6.2.3 kernel).
