Default Missing DVB driver(s) in centosplus 5.2 kernel

I've been trying to install a mythtv backend in centos 5.2 under Xen,
with PCI passthrough of a DVB-T tuner to the domU.


In theory I should just need to use the centosplus kernel to get the
additional video capture drivers. In practice I've got two problems, the
first of which I think is easy to solve.


Once I got the PCI device visible in the domU, I could load the saa7134
driver for the analogue section of the card, but I couldn't load the
saa7134_dvb driver for the digital section of the card, this driver is
missing from the centosplus kernel.


I've installed the kernel source, and modified the .config file as shown
in the patch below (the extra SAA7134_DVB settings are what my card
requires, but I figure there are potentially users of the BT848_DVB
driver that might appreciate that being included too).


After re-building the relevant modules, copying them to /lib/modules and
doing "depmod -a" I can load the saa7134_dvb module.


I saw another user who experienced the same issue with centos 5.1 and
Johnny Hughes said he would be willing to enable extra modules if they
would help.

Could the relevant .config files for centosplus kernels be patched as
follows?

My second problem is a bit harder, or possibly a sign that I've not

loaded in the domU, I see the following messages in dmesg

I'm not sure if the saa7134 driver is unusual in trying to perform an
ioremap which is causing the error?


dev->lmmio = ioremap(pci_resource_start(pci_dev,0), 0x1000);

Any suggestions on that one?

I will do this without Xen and slightly other hardware. (Terratec
Synergy 1200 card.) But my last MythTV install was when FC4 was still hot.

Will you be using the MythTV packages from ATrpms?

0.21 is a very big improvement

Yes, I'm using it already, I used to have a combined frontend/backend,
now the backend is on xen (and in a cupboard) and I have a nice new
dedicated frontend under the TV.

Just curious. What repo's are you using? Because it seems my first
attempts led straight to dependency hell.

I just need it to be a backend with a DVB-C card and webinterface for
programming. My MVPMC box will be my frontend.

The normal centos 5.2 repos (with centosplus for dvb drivers, although
now I use a self-built/patched centosplus kernel) and atrpms, nothing
else, no dependency issues :-)

similar setup to mine except my backend is virtual.

Could you forward the repo settings (/etc/yum.conf + /etc/yum.repos.d/*)
and package list (rpm -qa|sort) offlist? I do not think we need to
bother the list with that sort of details.

Hugo.
