Using new 6285 and 6985 together

[hovis]

Hello, we have been successfully using an older 6284 (DVB-T) and 6985 (DVB-S) together for months in the same server with no issue.

Today we received a new 6285 (note the xxx5 instead of the older xxx4!) for testing and installed it into our server and removed the older 6284 card.

We are now finding that the 6985 (satellite) card is generating errors every other second when the szap software does the read(). We are running all 4 inputs on the 6285 and 6985 simultaneously. (we process the entire transponder/multiplex of each input for remuxing and multicasting).

I know the 6285 card is very new, has anyone tried this and a satellite card in the same server together?

Linux kernel 3.8.0-33 (ubuntu 64bit) - driver version 130927

driver options in use:-

options saa716x_tbs-dvb int_type=1

Server: amd quad core 9600 (2.3Ghz).

HI,
This issue may relate with your mother board PCIE bandwidth,please try 'dvbtraffic -a 0 n' with 'szap',you will see the bandwidth is about 99000 kbit.
It means there are 8x 99000kbit data pass your PCIE bus,that would cause some data packages loss.
So please try to use the two patch files ,https://hotfile.com/dl/257317581/44d6f8c/patch.rar.html
with latest linux driver:
http://www.tbsdtv.com/download/document ... 130927.zip

replace them at \linux-tbs-drivers\linux\drivers\media\common\saa716x\ ,make and make install.
Then before shutdown the PC,you need to add driver option to "/etc/modprobe.d/tbs.conf",
options saa716x_tbs-dvb int_type=1
options saa716x_tbs-dvb enable_gts=0
That's means disable the TS generator with NULL packets ,the bandwidth will down to the nature level.
BTW,please send you feedback to support@tbsdtv.com and euro_support@tbsdtv.com, we can fast reply you.
Best regards!

@bob, is that patch still available anywhere? I might have a similar problem...
