h1. Known Good Kernel And Driver Combinations TV Headend is entirely dependent on a reliable combination of a kernel, drivers and hardware. In order to help people set up their server, this page will provide a list of combinations that people have found to work. h2. TBS 6982 DVB-S/S2, Kernel 4.8.0, on Ubuntu 16.04-LTS This combination of kernel and drivers was found to be stable: * Ubuntu: 16.04.5-LTS * kernel: 4.8.0-58-lowlatency * drivers: tbs-linux-drivers_v170330.zip * TV Headend: 4.3-1292~g9b9ee68~xenial The key factor in making the TBS card work was to ensure MSI Interrupts were enabled when the kernel module loads. Firstly, use "dpkg -l | grep linux-" to list This section of the linux kernel and associated packages. Use "dpkg -r" to remove kernel packages, and use "dpkg -P" to then purge everything. Check /boot remove any left over vmlinux and init.rd files etc; then likewise clean out /lib/modules. DO NOT REBOOT at any time when you have no kernel installed! Then install the kernel and associated packages, to get to the following state <pre> ii linux-headers-4.8.0-58 4.8.0-58.63~16.04.1 all Header files related to Linux kernel version 4.8.0 ii linux-headers-4.8.0-58-lowlatency 4.8.0-58.63~16.04.1 amd64 Linux kernel headers for version 4.8.0 on 64 bit x86 SMP ii linux-hwe-tools-4.8.0-58 4.8.0-58.63~16.04.1 amd64 Linux kernel version specific tools for version 4.8.0-58 ii linux-image-4.8.0-58-lowlatency 4.8.0-58.63~16.04.1 amd64 Linux kernel image for version 4.8.0 on 64 bit x86 SMP ii linux-signed-image-4.8.0-58-lowlatency 4.8.0-58.63~16.04.1 amd64 Signed kernel image lowlatency ii linux-tools-4.8.0-58-lowlatency 4.8.0-58.63~16.04.1 amd64 Linux kernel version specific tools for version 4.8.0-58 </pre> Then install the driver supplied by TBS. Create a script containing this: <pre> #!/bin/bash #VER="180822" #ZIPFILE="tbs-open-linux-drivers_v$VER.zip" #TARFILE=media_build-2018-0822.tar.bz2 VER="170330" ZIPFILE="tbs-linux-drivers_v170330.zip" TARFILE=linux-tbs-drivers.tar.bz2 DIR=/home/build mkdir -p "$DIR" cd "$DIR" if [ ! -f "$ZIPFILE" ] ; then wget "https://www.tbsiptv.com/download/common/$ZIPFILE" fi mkdir -p "$DIR/tbs_$VER" cd "$DIR/tbs_$VER" pwd ls -la "../$ZIPFILE" unzip "../$ZIPFILE" tar jxvf "$TARFILE" cd linux-tbs-drivers ./v4l/tbs-x86_64.sh make -j4 make install </pre> And execute it. Finally, set the driver to use MSI Interrupts by creating a file called "/etc/modprobe.d/tbs.conf" containing these lines: <pre> options tbs_pcie-dvb tbs_int_type=1 options saa716x_tbs-dvb int_type=1 </pre> It should now page will be possible to reboot your computer. Afterwards, check updated with more details, in the kernel module is loaded thus: <pre>$ lsmod | egrep "saa|dvb" saa716x_tbs_dvb 77824 0 </pre> And check that the interrupts are MSI by checking the /proc/interrupts, like this: <pre> $ egrep -i "saa|dvb" /proc/interrupts 31: 29757 0 0 0 PCI-MSI 1572864-edge SAA716x Core </pre> Also meanwhile see this: https://tvheadend.org/boards/5/topics/32496?r=34042#message-34042
