USB tuner problem - ET10K, kernel upgraded to 4.8.3

[ccs-ccs]

SUNDTEK USB TUNER CABLE TERRESTRIAL HD DVB-C/T/T2 works fine on OpenViX 4.2.026, but updating to 4.2.027 (which includes a kernel change from 4.0.1 to 4.8.3) causes the driver to fail to install and the box hangs. No other usb devices connected. (dmesg now on 4.2.028) .......

ViX 5.0.003 has now been released and the problem still hasn't been sorted.

I've currently got £100 worth of tuners which don't work - the SundTek usb T2 tuner and a hybrid DVB-C/T2 tuner. My ET10K has 4xDVB-C/T2 tuners. They all work independently, but 4 do not work at the same time. All 4 tuners have individual feeds (no loop thru's) - if I remove the feed to tuner D, tuner C stops working!!!

sure wait new update coming use old image and dont update

[ccs-ccs]

Thanks.

I should add that the ET10K hybrid DVB-C/T2 problem I mentioned in my previous comment has always been there, it is not as a result of the kernel upgrade. It would be great if it could be made to work - I was told that it would work, but everyone who has this configuration says that it doesn't.

[original-birdman]

When? You are still denying these Xtrend models a working kernel when one is available.

People have updated (which is how they know it is broken).

[ccs-ccs]

Is it really over 2 months since I first raised this issue?

[original-birdman]

Is it really nearly a month since I posted a fix (to revert to an kernel that actually works) for OpenVix (only), that was rejected by non-OpenViX people?

[atvcaptain]

internal we test new version with fix , and new features

[ccs-ccs]

@atvcaptain: internal we test new version with fix , and new features

That's good to hear, the "new features" sound intriguing.

Thanks again.

[original-birdman]

internal we test new version with fix , and new features

Meanwhile the rest of us have to live with a broken kernel, even though there was a perfectly good fix presented (for those who wanted a working kernel) which you rejected? And since you didn't see anything wrong with the 4.8.3 kernel (when there manifestly was), how confident should we be that you spot any similar problems with this new version?

OK - it looks promising. Let's hope it fixes things for all USB tuners,. and USB Wifi.

[RobvanderDoes]

I fail to see why ViX isn't testing this. After all ViX was (at least as far as I know) the only image that had issues with the current unofficial drivers.

[original-birdman]

Not fixed for the PCTV 292e triplestick, as it no longer loads any firmware, so now does nothing.

fix it and add correct firmware , that is the problem ?

[atvcaptain]

https://www.linuxtv.org/wiki/index.php/PCTV_Systems_tripleStick_T2_(292e)

[original-birdman]

I do have the correct firmware in place. There's set of different version at: http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/ but the issue is that this file is not being downloaded to the stick.

It was all working with the 4.0.1 kernel. It crashed with the 4.8.3 kernel, and with the 4.10.6 kernel it doesn't download the firmware to the stick.

My fix was to revert to the WORKING 4.0.1 kernel, but you won't let OpenViX do that.

[xtrendsupport]

Revert a kernel update is not a fix... Can you tell me what the manufacture PCTV say about this issue.

Please, if possible can you send a new dmesg and lsmod log with the new kernel. Maybe stupid question but did you install kernel-module-tveeprom and all other necessary modules

[atvcaptain]

you have not read the info linux tv org, driver and firmware must use the correct version

Please note that last version of the driver is needed as there is a strong symbiosis between drivers and firmware.

[original-birdman]

Please, if possible can you send a new dmesg and lsmod log with the new kernel.

For dmesg see the first comment on: https://github.com/oe-alliance/oe-alliance-core/commit/51ee8486c183b8e34be6a330f4bff92a68f5ed75#commitcomment-21762957

It isn't a fix for the kernel, but it is a fix for a broken OpenViX image.

[original-birdman]

I have read it. I have tried different versions of the firmware. You haven't read that I posted a link to where you can find 5 different versions.

[xtrendsupport]

Your (stripped?) log given no errors. Actually the device is initialize in a right way. em28xx 1-1:1.0: DVB: registering adapter 1 frontend 0 (Silicon Labs Si2168)...

The missing part is that enigma2 should make a Vtuner device so that's accessible as a nim device.

[original-birdman]

There are no errors. It just never gets round to downloading the firmware file.

The missing part is that enigma2 should make a Vtuner device so that's accessible as a nim device.

As I keep saying - all of this was working fine with the 4.0.1 kernel.

[Huevos]

The missing part is that enigma2 should make a Vtuner device so that's accessible as a nim device

How can it be a fault in enigma2? It works fine on every other brand of STB and also on the Xtrend when using the older drivers.

[original-birdman]

The missing part is that enigma2 should make a Vtuner device so that's accessible as a nim device

OpenViX 5.0.011 (release). uses kernel 4.8.3. When I start-up enigma2 with the triplestick in place, the firmware is downloaded to it and the dvb module crashes.

OpenVix 5.0.012.001 (dev). uses kernel 4.10.6. When I start-up enigma2 with the triplestick in place the firmware is not downloaded. The tuner is not visible to ViX.

The only difference between the enigma2 source code for those two versions on git is a few differences in some *.py files, non of which has anything to do with discovering tuners.

[Then there is also the older 5.0.002.006 (dev) that I built with the original 4.0.1 kernel. When I start-up enigma2 with the triplestick in place using that, the firmware is downloaded; the tuner is visible to ViX; the tuner works. You refuse to let ViX use it.]

ask steff send me a usb stick and i fix it for you

[ccs-ccs]

@original-birdman Any chance you could build an ET10k 4.10.6 image for me to try out the SundTek usb tuner? You could pop it in OpenVix/debug/CCS as before. Cheers ccs

[original-birdman]

ask steff send me a usb stick and i fix it for you

I doubt that he has one. He doesn't sell them.

PS: I've just noticed one thing about the 4.8.3 kernel crashes.

The "standard" 3 tuners show this:

Jan  1 01:00:16 et8000 user.info kernel: [    9.455000] platform dvb0.0: DVB: registering adapter 0 frontend 0 (DVB-T/T2/C)...
Jan  1 01:00:16 et8000 user.info kernel: [    9.471000] platform dvb0.0: DVB: registering adapter 0 frontend 1 (DVB-T/T2/C)...
Jan  1 01:00:16 et8000 user.info kernel: [    9.481000] platform dvb0.0: DVB: registering adapter 0 frontend 2 (DVB-T/T2/C)...

then the USB tuner shows as this (first plugged in)

Jan 24 16:43:01 et8000 user.info kernel: [ 6271.396000] usb 1-1: DVB: registering adapter 1 frontend 0 (Silicon Labs Si2168)...

then this, as enigma2 stars up

Jan 24 16:43:43 et8000 user.info kernel: [ 6311.381000] platform dvb0.0: DVB: registering adapter 0 frontend 3 (vtuner)...

So although the tuner was adapter 1, frontend 0, the xtrend dvb module was trying to do something with the non-existent adapter 0 frontend 3.

With the 4.10.6 dvb module it doesn't see this USB tuner at all.

[original-birdman]

OK. I can confirm that the USB stick is actually working with the 4.10.6 kernel, but is is NOT being seen by enigma2.

If I copy the files for dvbv5-scan from a Debian mips system onto the box I can run a scan - this works. The scan is on adaptor 1, frontend 0. the firmware download works OK.

But the /proc/bus/nim_sockets file (which is what enigma2 uses to get the list of adaptors to use( never contains any info about the USB tuner. The sysfs files and /dev/usb files do all get created as expected when I plug in the stick.

So the problem appears to be with the /proc/bus/nim_sockets file, which I presume is handled by the Xtrend kernel dvb module(?).

[ccs-ccs]

I've now been able to test the SundTek T2 usb tuner on 4.10.6 and can confirm that it works fine.

Here's my nim_sockets file.

What's odd is that sockets 2 and 3 have the same I2C_Device number. I wonder if this is why I can't record 4 different mux's using hybrid dvb-c/t/t2 tuners? All 4 work individually, but only 3 out 4 when all 4 are needed. Tuners C and D certainly share something, because Tuner C doesn't work when I remove the feed to tuner D.

root@et10000:~# cat  /proc/bus/nim_sockets
NIM Socket 0:
        Type: DVB-T2
        Name: Si2169

        Name: Si2169
        Has_Outputs: yes

        Has_Outputs: no
        Frontend_Device: 4
        I2C_Device: -1
root@et10000:~#

(Even though it is configured as DVB-T2, the /proc/bus/nim_sockets entry for the SundTek says it's DVB-C)

ask steff send me a usb stick and i fix it for you

I can see what he problem is!!! (But I don't know the solution).

Wandering through the OpenViX source I found that it is looking for an ep_00 entry in /sys/class/dvb/dvb1.frontend0/device to mark this as a USB tuner. So I had a look at the contents of this directory when running with the (working) 4.0.1 kernel and the (not working) 4.10.6 kernel. The contents are quite different (I do have both listings). The former contains an ep_00, while the latter contains an ep_84.

Fortunately, the script I used to generate the listing (and the content of each file) started with running /bin/pwd (to get the physical location) and there is a (very) significant difference.

4.0.1 has: /sys/devices/platform/ehci-brcm.0/usb1/1-1 4.10.6 has: /sys/devices/platform/ehci-brcm.0/usb1/1-1/1-1:1.0

i.e. 4.10.6 is one level further down. And if I look at that one level higher it contains the same info as does 4.0.1.

So the problem would appear to be that whatever is setting up the symlinks in the sysfs is getting it wrong!

There are two symlinks along the way to /sys/class/dvb/dvb1.frontend0/device, so I'll need to re-flash the 4.0.1 image to find out which the right ones are (and hence which the wrong one is in 4.10.6.

[original-birdman]

As a result of this symlink oddity the dvb directory, and also the i2c-7 and i2c-8 ones, end up one level further down in the 4.10.6 kernel sysfs file-system. The fact that the dvb one is one level further down results in its device symlink pointing to the wrong location and enigma2 not realizing that it is a USB tuner.

It looks like the dvb1.frontend0 symlink is at fault.

In 4.0.1 this is: dvb1.frontend0 -> ../../devices/platform/ehci-brcm.0/usb1/1-1/dvb/dvb1.frontend0 In 4.10.6 it is: dvb1.frontend0 -> ../../devices/platform/ehci-brcm.0/usb1/1-1/1-1:1.0/dvb/dvb1.frontend0

in both cases the device symlink is to an entry 3 levels higher.

[original-birdman]

Thanks, but it sill doesn't work for me on OpenVix. The enigma2-plugin-drivers-ct2-dvb-usb-pctv292e package just adds kernel-module-em28xx-rc beyond what I already have, so I installed that (and removed kernel-module-si21xx, which was never used anyway). boot up still shows this:

with em28xx registering the device as 1-1:1.0 (i.e. one level below where it "should" be).

With the 4.0.1 kernel this looked like:

with the em28xx register being different, and then "platform" picking it up for the vtuner.

What does the OpenATV message file show for this?

[atvcaptain]

check atv e2 git and update vix e2 fix your issue

https://github.com/openatv/enigma2/commit/16c47dd2e78ca70c5ad2467d0d2952628050a3ec

[original-birdman]

Well, that makes the tuner show up. A recording started just after I tested that, so I'll have to wait to check that the tuner is usable (it's certainly configurable, as I had to switch it from the default DVB-C to DVB-T2). The code, though, strikes me as a horrible kludge. I have a feeling that it should be check for something specific not "is endpoint 0 there - if not do we happen to be somewhere else with an endpoint 84, so there must be an endpoint 0 above it....".

But many thanks anyway.

[original-birdman]

I can confirm that it is now working.

(It can't get a signal from the 2 low-power muxes broadcast to me - something I've only noticed as a result of this testing, but it's fine with the other ones).

[original-birdman]

The code, though, strikes me as a horrible kludge.

My gut feeling is that you should read the symlink at /sys/class/dvb/dvb%d.frontend%d/device/subsystem and check that it ends with /bus/usb (or just /usb)
