commit 5fa88151ecdb ("[media] dvb-usb-cxusb: Geniatech T230 - resync TS FIFO after lock") does not solve the problem for all devices. This is the same issue reported on the T230C, which was moved to the dvbsky.c driver to work around this issue in commit 5742240577b6 ("media: dvbsky: MyGica T230C support"). In addition, the cxusb driver causes an oops when unplugging the device while streaming; this problem does not happen any more.

2019-03-19media: dvbsky: Avoid leaking dvb frontendStefan Brüns1-8/+10
Commit 14f4eaeddabc ("media: dvbsky: fix driver unregister logic") fixed a use-after-free by removing the reference to the frontend after deleting the backing i2c device. This has the unfortunate side effect the frontend device is never freed in the dvb core leaving a dangling device, leading to errors when the dvb core tries to register the frontend after e.g. a replug as reported here: https://www.spinics.net/lists/linux-media/msg138181.html media: dvbsky: issues with DVBSky T680CI === [ 561.119145] sp2 8-0040: CIMaX SP2 successfully attached [ 561.119161] usb 2-3: DVB: registering adapter 0 frontend 0 (Silicon Labs Si2168)... [ 561.119174] sysfs: cannot create duplicate filename '/class/dvb/ dvb0.frontend0' === The use after free happened as dvb_usbv2_disconnect calls in this order: - dvb_usb_device::props->exit(...) - dvb_usbv2_adapter_frontend_exit(...) + if (fe) dvb_unregister_frontend(fe) + dvb_usb_device::props->frontend_detach(...) Moving the release of the i2c device from exit() to frontend_detach() avoids the dangling pointer access and allows the core to unregister the frontend. This was originally reported for a DVBSky T680CI, but it also affects the MyGica T230C. As all supported devices structure the registration/ unregistration identically, apply the change for all device types.

2018-10-05Revert "media: dvbsky: use just one mutex for serializing device R/W ops"Mauro Carvalho Chehab1-6/+10
As pointed at: https://bugzilla.kernel.org/show_bug.cgi?id=199323 This patch causes a bad effect on RPi. I suspect that the root cause is at the USB out of tree RPi driver, with uses high priority interrupts instead of normal ones. Anyway, as this patch is mostly a cleanup, better to revert it.

2015-06-10[media] TS2020: Calculate tuner gain correctlyDavid Howells1-0/+2
The TS2020 and TS2022 tuners take an input from the demodulator indicating the AGC setting on that component that is then used to influence the tuner's own gain. This should be taken into account when calculating the gain and signal strength. Further, the existing TS2020 driver miscalculates the signal strength as the result of its calculations can exceed the storage capacity of the 16-bit word used to return it to userspace. To this end: (1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that the tuner can call to get the AGC PWM value from the demodulator. (2) Modify the TS2020 driver to calculate the gain according to Montage's specification with the adjustment that we produce a negative value and scale it to 0.001dB units (which is what the DVBv5 API will require): (a) Callback to the demodulator to retrieve the AGC PWM value and then turn that into Vagc for incorporation in the calculations. If the callback is unset, assume a Vagc of 0. (b) Calculate the tuner gain from a combination of Vagc and the tuner's RF gain and baseband gain settings. (3) Turn this into a percentage signal strength as per Montage's specification for return to userspace with the DVBv3 API. (4) Provide a function in the M88DS3103 demodulator driver that can be used to get the AGC PWM value on behalf of the tuner. (5) The ts2020_config.get_agc_pwm function should be set by the code that stitches together the drivers for each card. For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022, set the get_agc_pwm function to point to m88ds3103_get_agc_pwm. I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022. Thanks to Montage for providing access to information about the workings of these parts.

2015-06-09[media] dvb: Get rid of typedev usage for enumsMauro Carvalho Chehab1-5/+6
The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

2015-05-12[media] si2157: support selection of IF interfaceOlli Salonen1-0/+2
The chips supported by the si2157 driver have two IF outputs (either pins 12+13 or pins 9+11). Instead of hardcoding the output to be used add an option to choose which output shall be used. As this patch changes the default behaviour, the IF interface is specified in each driver currently using si2157 driver. This is to keep bisectability.
