maybe you should have a look here ?h=montage-3103b.v2
this is likely upstreamd from Brad and if you have some patch he is likely helpful in getting it upstream too
This is his gh repo, just open an issue if you have questions/patches for the driver Issues · b-rad-NDi/Ubuntu-media-tree-kernel-builder · GitHub
I already tried with brad's patches but I got no luck just too many errors and I reported to him as issue
I am not a driver developer I can't go further from here
m88ds3103b shares more code from m88rs6000 rather than m88ds310's code
setting ts_clk=18000 with more channels gone even it can't fetch some of channel names
when I check m88rs6000 code
if CI mode enabled ts_clk set 8000 without CI mode ts_clk=16000
parallel/CI mode target_mclk=144000 serial mode=96000
with my patch i got the best result
Any chance the channels which still don't work are on transponders with a bit rate higher than 53 Mb/s? I'm using channels available from the UK at 28.2°E, so I haven't really been able to test it with any transponder carrying more data than that, unless you count the 8k test channel, which doesn't work. I might have another go with the upstream drivers at some point, and see if they are working any better.
some of high bitrate channels are ok (higher then 53 Mb/s) after changing ts_clk and target_mclk
but still some of transponders are not showning or green/broken video
with ts_clk=16000 and target_mclk = 144000 copied from m88rs6000.c values
more channels shows up and running good but not perfect still some channels are not stable
i am having the same problem
it can't tune some of transponders it's not related to encryption
Looks like ds3103 B revision use same firmware from m88rs6000
Maybe ds3103b is alike from m88rs6000 but without built-in tuner
Modifying in kernel m88rs6000 code may can work
and if it will work we will get mainline kernel support
when I checked ds3000_firmware.h I found ds3103 firmware have completely different from old ones
old firmwares(ds300x/ds3103) header starts with 0x83, 0x01, 0x00, 0x30
new one header starts with 0x8a, 0x11, 0x11, 0x28
if the problem is caused by the wrong firmware loading but I dont know
does vendor driver upload firmware from ds3000_firmware.h or /lib/firmware/dvb-fe-ds3103.fw(old header)
Hi,
Vendor sent to me new driver and there is support for DS3103B
I don't have V3.0 hardware i can't test for it
But still I can't watch high bitrate channels with v2.1 board
i think it is related to usb bandwidth problem of linux
ds3k driver is better than ds3000 but still it is not same quality like windowz driver
tested with su3000 v2.1
