cx23885: DVBSky S952 dvb_register failed err = -22

cx23885: DVBSky S952 dvb_register failed err = -22

[Ole Ernst]

Hi,

using linux-3.19.1-1 (Archlinux) I get the following output while
booting without the media-build-tree provided by DVBSky:

cx23885 driver version 0.0.4 loaded
cx23885 0000:04:00.0: enabling device (0000 -> 0002)

Obviously there are no device in /dev/dvb. Using the media-build-tree
works just fine though. The following firmware files are installed in
/usr/lib/firmware:
dvb-demod-m88ds3103.fw
dvb-demod-m88rs6000.fw
dvb-demod-si2168-a20-01.fw
dvb-demod-si2168-a30-01.fw
dvb-demod-si2168-b40-01.fw
dvb-fe-ds300x.fw
dvb-fe-ds3103.fw
dvb-fe-rs6000.fw
dvb-tuner-si2158-a20-01.fw

Output of lspci -vvvnn:
https://gist.githubusercontent.com/olebowle/6a4108363a9d1f7dd033/raw/lscpi

I also set the module parameters debug, i2c_debug, irq_debug and
irq_debug in cx23885.
The output is pretty verbose and can be found here:
https://gist.githubusercontent.com/olebowle/6a4108363a9d1f7dd033/raw/debug.log

Thanks,
Ole

Re: cx23885: DVBSky S952 dvb_register failed err = -22

[Ole Ernst]

Hi,

I added some printk in cx23885-dvb.c and the problem is in
i2c_new_device:
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/drivers/media/pci/cx23885/cx23885-dvb.c?id=refs/tags/v3.19.1#n1935

The returned client_tuner is not NULL, but client_tuner->dev.driver is.
Hence it will goto frontend_detach, which will then return -EINVAL. Any
idea why client_tuner->dev.driver is NULL?

Thanks,
Ole

[Antti Palosaari]

You don't have m88ts2022 driver installed.

Hello,

what is the "chip_id" debug output from m88ts2022 module?

I think you maybe hold the old S952 card.
Its satellite tuner is M88TS2020, not M88TS2022.

Best Regards,
Max

Re: cx23885: DVBSky S952 dvb_register failed err = -22

[Ole Ernst]

Hi Max,

I get a chip_id of 0x81, which returns -ENODEV in the default branch of
the subsequent switch. So I guess my S952 is too old? :-( How hard would
it be to add support for it?

Thanks,
Ole

If it is m88ts2020, there is a tuner driver "ts2020" in "dvb-frontends" directory.
If fail to load m88ts2022 driver, then try to load ts2020 driver.
m88ts2022 driver is an i2c driver, but ts2020 is traditional dvb-attach driver.
Please check the other code using ts2020 for reference.

Re: cx23885: DVBSky S952 dvb_register failed err = -22

[Ole Ernst]

Hi Max,

I'm afraid I'm not experienced enough to adapt the ts2020 driver to
interwork with the current kernel driver for the S952. I'd be more than
happy to test patches though!

Thanks,
Ole

I will migrate M88TS2022 to TS2020 and it will start working after that.

Very much appreciated, thanks Antti! Let me know, if you need someone to

Could you test that tree?
http://git.linuxtv.org/cgit.cgi/anttip/media_tree.git/log/?h=ts2020

git clone -b ts2020 git://linuxtv.org/anttip/media_tree.git

then compile and install whole kernel

Re: cx23885: DVBSky S952 dvb_register failed err = -22

[Ole Ernst]

Hi Annti,

I generated a patch using git diff 8a56b6b..5786103 on your branch and
applied it to the current media_build tree, because I'm more experienced
with it as compared to building my own kernels. After installing it, I
removed m88ts2022.ko.gz shipped with my kernel and ran depmod -a. After
a power-down/up cycle I can see
/dev/dvb/adapter{0,1}/{demux,dvr,frontend,net}0. Unfortunately the
frontends time out while tunning to a channel.

It looks as if the firmware dvb-fe-ds3103.fw is not getting downloaded
with your patch. I thought there shouldn't be nodes in /dev/dvb/ in this
case?
To roll back I reinstalled the old tree, moving the original
m88ts2022.ko.gz back in and running depmod -a. Rebooting didn't bring
the S952 up, it said:

Mär 24 10:39:07 htpc kernel: Unable to find Montage chip
Mär 24 10:39:07 htpc kernel: cx23885[0]: frontend initialization failed
Mär 24 10:39:07 htpc kernel: cx23885_dvb_register() dvb_register failed
err = -22
Mär 24 10:39:07 htpc kernel: cx23885_dev_setup() Failed to register dvb
adapters on VID_B

So maybe it left it in a strange/undefined state? I had to poweroff the
machine and start from there. Afterwards everything is fine again.

Thanks,
Ole

Looks strange as firmware is not downloaded. It is downloaded on when 
first tuning attempt is done, so nodes are created in any case. TS2020 
tuner is detected correctly, which looks somehow promising. Could you 
test my patches again as I have done some changes (tree is rebased).

Hi Antti,

I don't know what went wrong on first try, but after enabling some debug
output I can see the firmware being downloaded.

However, the tuner still times out even with your rebase. I sometimes
also get this output from vdr:

Which basically says the waiting time has exceeded.

I was playing a bit with femon plugin and often there will be a regained
lock, with no picture though. Two times I also got a divide error:

Someone has reported SCR/Unicable does not work with that demod driver, 
but I have no personal experience from whole thing... Could you try 
direct connection to LNB?

m88ds3103_read_snr crash look bad. No idea how it could happen.

I will test a direct connection over Easter, as I don't have physical
access to the htpc right now. I will try to get someone else to test
your patch, who hopefully doesn't use SCR.

Hi Antti,

I was able to test your current tree (8a56b6b..754594d) without SCR and
the frontends still run into a timeout. There seems to be an issue with
the patch in general. Is there something else I can test/try or do you
require some debug output?

Thanks,
Ole

It is a bit hard to debug remotely... Somehow it must be find out where 
it starts failing. Is there some I/O communication problem with chips or 
tuning is failing for some other reason.

I have only old DS3000/TS2020 USB device and newer DS3103/TS2022 USB 
device, but no DS3103/TS2020 combination.

Could you try w_scan for example? Or szap? Some simple commandline tool.

Antti
