Yeah, I've been busy, quite ironic though that the day before you came along I started working on it again.....   I uploaded v6.6.6 last night.   There are some caveats, can't get

DEPRECATED

@trurl Please lock this thread.  Due to an unexpected announcement from @limetech about Nvidia, I have since made the decision to do no further development work on Unraid. I'm quitting Unraid work.  A

cx23885 present in the release? I'm afk at the moment so can't check.

@CHBMB Yeah the driver is there:

root@USS-Enterprise:~# find /lib/modules/4.12.14-unRAID | grep cx23885
/lib/modules/4.12.14-unRAID/kernel/drivers/media/pci/cx23885
/lib/modules/4.12.14-unRAID/kernel/drivers/media/pci/cx23885/altera-ci.ko.xz
/lib/modules/4.12.14-unRAID/kernel/drivers/media/pci/cx23885/cx23885.ko.xz

Just throws a dirty error when trying to load it

Problem is Hauppage only explicitly support Ubuntu, not even sure where to report an error.

@CHBMB I did find this: https://patchwork.kernel.org/patch/9717037/
Unsure if it is related, the videobuf2_memops errors are exactly the same, So I wonder if the solution they suggest would work (Enable VB2).

Am happy to test if you want to provide me a test build

Any chance I can get you on board with this then?  I'm pretty time poor at the moment, and debugging cards that I don't own is a major pain in the ass.

 

Compiling the kernel for the LibreELEC build involves two scripts.

 

1. https://github.com/CHBMB/Unraid-DVB/blob/master/build_scripts/kernel-compile-module.sh

2. https://github.com/CHBMB/Unraid-DVB/blob/master/build_scripts/libreelec-module.sh

 

Now when you look at them please bear in mind I don't actually work with Linux/computers at all.  So go easy on me!

Packages are pulled from Slackware current, so shouldn't be out of date.

the FILE_LIST my build seems to be pulling is out of date (Must be a mirror out of sync)
I managed to get a build done, but it caused my server to hose itself - Parity drive went nuts - Do you having this running in a test env for your builds? e.g. a test/dev version of unraid or do you build these on your live server ?

I wonder is LimeTech will give us a test license (1 disk in array) for developing - Since a trial license only lives for so long. REALLY not comfortable doing this on my live machine (I already have a failed drive im trying to replace, dont want my parity to disappear :P )

@ProGEEK & @Zan Try replacing bzmodules and bzfirmware of the current LibreELEC rc9f release with the ones in this zip file and reboot.  See if that fixes the Hauppage issue.

 

No luck,

 

Still getting the modprobe cx23885 errors from before.

 

I'll try to build it as well, using your script @CHBMB, and just step through the media_build part to see what Mauro and Matthias are referring to in this https://patchwork.kernel.org/patch/9717037/

Might take me a few days, so I'll let you know how I go then.

I just can't figure it out. Have tried a few things including deleting of the compressed modules from the original kernel compile of kernel-compile-module.sh, as per https://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

 

and still no luck.

 

@ProGEEK, my process was to create a stock 6-4-0-rc9f USB stick using the unraid USB creator tool (https://forums.lime-technology.com/topic/59025-unraid-usb-creator-tool-version-01-beta/), then just ran the following steps:

mkdir /unraid-dvb
cd /unraid-dvb
wget https://raw.githubusercontent.com/CHBMB/Unraid-DVB/master/user.scripts/scripts/unraid-dvb/script .
sed -i -e 's/mnt\/disk1\//unraid-/g' script
chmod +x script
./script
sed '/libre/d' /unraid-dvb/build.sh | sed '/tbs-os/d' | sed '/dd-module/d' | sed '/upload/d' | sed '$ s/&& \//' > /unraid-dvb/build-new.sh
chmod +x /unraid-dvb/build-new.sh
#Remove compressed modules as per https://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers
for file in `find /lib/modules -name "*.ko"`; do if [[ -e $file.xz ]]; then rm $file.xz; fi; done
/unraid-dvb/media-build-2017-09-20/make reload
/unraid-dvb/media-build-2017-09-20/depmod -a
rm /unraid-dvb/6-4-0-rc9f/tbs-crazy-dvbst/bzmodules
mksquashfs /lib/modules/4.12.14-unRAID/ /unraid-dvb/6-4-0-rc9f/tbs-crazy-dvbst/bzmodules -keep-as-directory -noappend

Ok guys, keep at it, I'm also chatting to cvh over at libreelec about this and he's been helpful, and there's something else we can try, but I'm struggling a bit with free time at the moment but give me a week or so and hopefully I'll get a chance.

My Theory is that the compiled modules cannot find the symbols needed that are compiled into the kernel.

These USUALLY live at /boot/System.map-$(uname -r)
https://en.wikipedia.org/wiki/System.map#Filesystem_location

I am testing a build by building the kernel, trying to load the module (With the System.map file missing) then im gonna move this file into position and see if there is a difference.

I'm near the end of the build so will report back in an hour or so

EDIT: Nope, No-go. As far as I can tell, FRAME_VECTOR isnt being included in the kernel, and im unsure why.
 

root@Tower:/mnt/user/UnRAID/kernel# cat /proc/kallsyms | grep frame_vector_create
root@Tower:/mnt/user/UnRAID/kernel#

Run the same on my laptop:

[rdavies@USS-Stargazer build]$ cat /proc/kallsyms | grep frame_vector_create
ffffffff86223780 T frame_vector_create
[rdavies@USS-Stargazer build]$

So need to work out why this isnt being included in the build when it is specified in the config
