Assign tuner numbers

Post by zorrua » Fri Jun 22, 2018 12:31 pm

Hello,

I am using dvb modules option to assign each DVB tuner to different device numbers:

Code: Select all

# cat /etc/modprobe.d/dvb.conf
options dvb_usb_dib0700 adapter_nr=3
options dvb_usb_af9015 adapter_nr=2

Code: Select all

# ls -l /dev/dvb/
total 0
drwxr-xr-x 2 root root 120 jun 22 14:20 adapter2
drwxr-xr-x 2 root root 120 jun 22 14:20 adapter3
How are the minisatip tuners assigned?

Image

Minisat tuner 0 is dev 2 and tuner 1 is dev 3?

Is it possible to match the tuners in minisatip with the Linux system?

Thanks for all your help.

Kind regards.

Hi,

At this point is not really possible because the numbers are assigned based on first adapters detected. For example you could have /dev/dvb/adapter0/frontend0-8. There are all kinds of combinations that could prevent you from assuming that adapter2 at the OS level is adapter2 in minisatip

Thanks cata,

So, could I asume that if I have adapter2 and adapter3, the adapter2 is going to be always tuner 0 and adapter 3 the tuner 1?

yeah, the logic is that it iterates on all adapterX/frontendY with X=[0...32] and Y=[0..32] until it finds all the adapters

Great!

So I could asume that the assigment will go in order.

Best regards.!

Hi cata,

I have some trouble understanding the -e parameter.

Code: Select all

[b]-e --enable-adapters list_of_enabled adapters: enable only specified adapters[/b]
eg: -e 0-2,5,7 (no spaces between parameters)
keep in mind that the first adapters are the local ones starting with 0 after that are the satip adapters if you have 3 local dvb cards 0-2 will be the local adapters, 3,4, ... will be the satip servers specified with argument -s

I have 3 DVBC tuners of which I want to exclude 1 in minisatip. I have excluded 1 TT-4650-CI tuners with adding this in /etc/modprobe.d/dvb.conf

Code: Select all

# TT-4650-CI
options dvb_usb_dvbsky adapter_nr=5
So now I have:

/dev/dvb/adapter0 (TBS 5881)
/dev/dvb/adapter1 (TBS 5881)
/dev/dvb/adapter5 (TT-4650-CI)

How can I start minisatip with only the TBS tuners? The order of those doesn't really matter.

you should use:

-e 0,1
