Re: DViCO Fusion HDTV DVB-T Dual Express [PATCH]

[stev391@xxxxxxxxx]

Thom,

Disclaimer: This not guranteed to work and will break any webcams you have running on ubuntu, this is reversable by reinstalling the "linux-*" packages that you have already installed.

I can't seem to find any information about that version of Mythbuntu, is it supposed to be version 8.04? Anyway the following will work for previous versions as well.
All commands to be run in a terminal.

Step 1, Install the required packages to retrieve and compile the source (you also need to install the linux-headers that match your kernel, which is done by the following command as well)
sudo apt-get install mercurial build-essential patch linux-headers-`uname -r`

Step 2, Retrieve the v4l-dvb sources
hg clone http://linuxtv.org/hg/v4l-dvb

Step 3, Apply patch (which was an attachment on the previous email)
cd v4l-dvb
patch -p1 < ../DViCO_FUSIONHDTV_DVB_T_DUAL_EXP_v2.patch

Step 4, Compile which will take awhile... (maybe time to make a cup of coffee)
make all

Step 5 Remove the old modules as this causes issues when loading the modules later(this depends on version of ubuntu)
8.04:  cd /lib/modules/`uname -r`/ubuntu/media
cd /lib/modules/`uname -r`/kernel/drivers/media
sudo rm -r common
sudo rm -r dvb
sudo rm -r radio
sudo rm -r video

Step 6: return to v4l-dvb directory and run:
sudo make install

Step 7: Update the initramfs:
sudo dpkg-reconfigure linux-ubuntu-modules-`uname -r`

Step 8: Reboot and see if it worked
sudo shutdown -r now

If this didn't work with my patch please send me the output of dmesg and any relevant logs of the application that you used to identify the problem with (eg mythbackend log). Then try replacing step 2 & 3 with (This uses the older branch by Chris Pascoe, whose code I'm trying to update to bring into the main v4l-dvb):
hg clone http://linuxtv.org/hg/~pascoe/xc-test/
cd xc-test

If this still doesn't work and your dvb system is broken just reinstall your linux-* packages.

Regards,
Stephen

Hi

I have one of these cards and have been wanting to get it working
under Mythbuntu 8.01 and this looks promising.

I'm fairly new to Linux and have no idea as to how to apply this
patch to my existing Mythbuntu installation and would be very
grateful for some pointers as to how to go about it. I'm sure there
are many people in the same situation and I would be happy to write
it up as a howto and post to relevant interest groups.

Thank you for your work on this.

Regards
Thom



----------------------------------------
I have updated my patch (from a week ago) and is included inline
below as well as an attachment. The issue that was noticed and
mentioned in previous posts regarding to tuners not resetting was
possibly due to several "__FUNCTION_" in the tuner reset code,
these should be "__func__", which is fixed in the attached patch.

This patch is against the v4l-dvb head (7897, 2e9a2e4c8435) and is
intended to merge Chris Pascoe's work into the current head to
enable support for the DViCO Fusion HDTV DVB-T Dual Express (PCIe).
This enables systems with different tuners to take advantage of
other experimental drivers, (for example my TV Walker Twin USB
tuner).

Regards,

Stephen
