I've been searching Google, the Wiki and the forum, trying on my own and asking for help in ##slackware on freenode, and I can't figure out how to compile a new kernel with added DVB drivers directly from my existing unRAID installation.

 

The "methods of user customization" Wiki page says that it should be possible to do this on a standard unRAID installation booting from from the flash, but all information I can find starts with installing a full Slackware development environment.

I just want to add DVB drivers, and keep everything else the same, so that I can run Tvheadend on my unRAID server. I'm running 5.0 beta 8c.

 

I downloaded the source for the same kernel that is already installed, 2.6.37.6, from kernel.org, extracted it, copied /usr/src/linux-2.6.37.6-unRAID/.config to /usr/src/linux-2.6.37.6, ran make oldconfig, answered no (the default) for the various new MD_* options, then ran make menuconfig.

 

In between, I downloaded and installed whatever make complained was missing.

 

In menuconfig, I looked in almost every single menu I could for something that looked like DVB drivers. I think it should be in device drivers > multimedia or something like that, but every place that looks like it might be it, is empty or has other things in it that don't mean anything to me.

 

When I grep the src for the particular driver that I am looking for (saa7164), it is there in drivers/media/video/saa7164, but it's not listed in the old .config or the updated one.

 

I don't want to install a full Slackware system, then try to get unRAID working on it. I just want to add this DVB driver so that Tvheadend will work, and otherwise keep everything as close to stock unRAID as possible.

 

How can I recompile the kernel to include this driver, from within my existing unRAID 5.0 beta 8c installation, booting from the flash?

 

Cheers.

 

...check this article from the wiki: http://lime-technology.com/wiki/index.php?title=Installing_VirtualBox_in_unRAID

It gives a great example on how to compile a new kernel in an existing unRAID.

 

Thanks for the link. I assume I should do make oldconfig, then make menuconfig (to enable the DVB drivers) before running make? When I do, I still can't find anything related to DVB or saa7164 in there.

 

I also get this warning during make oldconfig. Not sure if it means anything.

Is there something special I need to do to make the DVB drivers visible, so that I can enable them?

 

Cheers.

 

I am working on the same thing (getting tvheadend working on unRAID) and I am almost there.

 

My understanding is that because of the symlinks you will only succeed in repackaging the bzImage and bzroot on a stock unRAID (without a dev machine) if you are doing it on one of your drives instead of the USB (which is FAT and doesn't support symlinking).

 

...myself I am working on it on a Dev machine.
