media_build updated Update blacklist for <5.19

[elkizana]

thanks how can update the the media_folder ?

[elkizana]

got this

[crazycat69]

another update, tested with 5.16.20-051620-generic

[elkizana]

compiled but unfortunately the graphics are broken, nouveau doesn't seem to work

[crazycat69]

Use install.sh script

[elkizana]

did it the problem still even the sound is gone

[crazycat69]

Maybe you delete kernel media modules before install ?

[elkizana]

Maybe you delete kernel media modules before install ?

with a fresh kernel :

• when I use install.sh it compiles and install normally but the driver doesn't load up
• when I install it manually the driver loads up but the graphics and the sound are broken. the steps I put :

git clone https://github.com/tbsdtv/media_build.git git clone --depth=1 https://github.com/tbsdtv/linux_media.git -b latest ./media cd media_build make dir DIR=../media make distclean make -j4 make install reboot

[crazycat69]

what dvb device used ?

[elkizana]

TechniSat SkyStar 2 eXpress HD I have tested several kernels; kernels 5.10 and below work fine. The ones above 5.10 install but broke the graphics.

[crazycat69]

Compile/install with install.sh and try: modinfo saa716x_tbs_dvb modprobe saa716x_tbs_dvb dmesg

[elkizana]

dmesg.txt

[elkizana]

it's working now. I installed it with the the and executed the commands. Strange.

[crazycat69]

ok you use old mainline unsupported kernels 5.16, 5.18 instead current ubuntu kernels ?

[elkizana]

Now i'm using 5.18.0 (or below) because I have WiFi card that neither works out of the box in the 6.x kernels nor could I install the driver I'm using for it now. Thank you for the work you are doing for the community @crazycat69
