On real devices, signal strength is always a negative number when represented in dBm. A more interesting range is to use dBmV (which is what Kaffeine does, for example). The conversion from the two units are simple: dBmV = dBm - 108 Usually, signal strength ranges up to 100dBmV. Adjust the maximum value to be around 74 dBmV, when there's no frequency shift, which represents a good signal. With that, Kaffeine displays it a lot better.

The dvb_frontend will already call status periodically, when a channel is tuned. So, no need to have a work queue for such purpose. Signed-off-by: -

The current stats code is broken on so many ways. It ends reporting 0 for signal strengh, and the work queue doesn't run. If it would run, the code would crash. Fix such issues and add the minimum stuff for DVBv5 stats. Right now, only strength and cnr and UCB are implemented. pre/post BER stats will always return zero. Signed-off-by: -

The code there is already doing the right thing, as it uses value & 0xff, value & 0xff00, which already ensures the expected endiannes. So, it doesn't make any sense to touch the order depending on the CPU endiannes. Yet, as pointed by Daniel at the mailing list: https://lore.kernel.org/linux-media/e614351c-215c-c048-52af-7c200b164f41@xs4all.nl/T/#m8d221684a151833966359c2ed8bdce0f0ee4e5fd The reverse code is needed by the decoder. So, keep it no matter the endiannes. Signed-off-by:

Use 474 MHz frequency for DVB-T/DVB-C, as this is the at the channel range that it is valid on most places for DVB-T. In the case of DVB-S, let's add Astra 19.2E initial frequency at the scan files as the default, e. g. 12.5515 GHz. Signed-off-by: -

Right now, there are some issues at the tuning logic: 1) the config struct is not copied at the tuner driver. so, it won't use any frequency table at all; 2) the code that checks for frequency shifts is called at set_params. So, lock_status will never be zeroed; 3) the signal strength will also report a strong signal, even if not tuned; 4) the logic is not excluding non-set frequencies. Fix those issues. Signed-off-by: -

Digital TV devices consist of several independent hardware components which are controlled by different drivers. Each media device is controlled by a group of cooperating drivers with the bridge driver as the main driver. This patch adds a bridge driver for the Virtual Digital TV driver [vidtv]. The bridge driver binds to the other drivers, that is, vidtv_tuner and vidtv_demod and implements the digital demux logic, providing userspace with a MPEG Transport Stream. The MPEG related code is split in the following way: - vidtv_ts: code to work with MPEG TS packets, such as TS headers, adaptation fields, PCR packets and NULL packets. - vidtv_psi: this is the PSI generator. PSI packets contain general information about a MPEG Transport Stream. A PSI generator is needed so userspace apps can retrieve information about the Transport Stream and eventually tune into a (dummy) channel. Because the generator is implemented in a separate file, it can be reused elsewhere in the media subsystem. Currently vidtv supports working with 3 PSI tables: PAT, PMT and SDT. - vidtv_pes: implements the PES logic to convert encoder data into MPEG TS packets. These can then be fed into a TS multiplexer and eventually into userspace. - vidtv_s302m: implements a S302M encoder to make it possible to insert PCM audio data in the generated MPEG Transport Stream. This shall enable passing an audio signal into userspace so it can be decoded and played by media software. - vidtv_channels: Implements a 'channel' abstraction When vidtv boots, it will create some hardcoded channels: Their services will be concatenated to populate the SDT. Their programs will be concatenated to populate the PAT For each program in the PAT, a PMT section will be created The PMT section for a channel will be assigned its streams. Every stream will have its corresponding encoder polled to produce TS packets These packets may be interleaved by the mux and then delivered to the bridge - vidtv_mux - Implements a MPEG TS mux, loosely based on the ffmpeg implementation The multiplexer is responsible for polling encoders, interleaving packets, padding the resulting stream with NULL packets if necessary and then delivering the resulting TS packets to the bridge driver so it can feed the demux.

Implement a I2C demodulator driver, simulating support for DVB-T, DVB-C and DVB-S. This demodulator will periodically check the signal quality against a table and drop the TS lock if it drops below a threshold value, regaining it in the event that the signal improves. Signed-off-by:

The virtual DVB test driver serves as a reference DVB driver and helps validate the existing APIs in the media subsystem. It can also aid developers working on userspace applications. This dummy tuner should support common TV standards such as DVB-T/T2/S/S2, ISDB-T and ATSC when completed. Signed-off-by:

It sounds that earlier versions of GCC have troubles when doing const math at compile time, if no typecast is used: on i386: ERROR: modpost: "__floatunsidf" [drivers/media/pci/ttpci/dvb-ttpci.ko] undefined! ERROR: modpost: "__ltdf2" [drivers/media/pci/ttpci/dvb-ttpci.ko] undefined! The warning was generated on gcc (SUSE Linux) 7.5.0. Gcc 9.2 compiles it fine. As an added bonus, it also fixes this objtool warning: drivers/media/pci/ttpci/av7110_v4l.c:163:11: error: SSE register return with SSE disabled Reported-by:

v4l2_async_notifier_add_subdev() requires the asd to be allocated dynamically, but the max9286 driver embeds it in the max9286_source structure. This causes memory corruption when the notifier is destroyed at remove time with v4l2_async_notifier_cleanup(). Fix this issue by registering the asd with v4l2_async_notifier_add_fwnode_subdev(), which allocates it dynamically internally. A new max9286_asd structure is introduced, to store a pointer to the corresonding max9286_source that needs to be accessed from bound and unbind callbacks. There's no need to take an extra explicit reference to the fwnode anymore as v4l2_async_notifier_add_fwnode_subdev() does so internally. While at it, use %u instead of %d to print the unsigned index in the error message from the v4l2_async_notifier_add_fwnode_subdev() error path.

The v4l2_async_notifier_add_subdev() function requires the asd pointer it receives to be allocated dynamically, but doesn't explicitly say so. Only one driver out of 13 get its right (atmel-sama5d2-isc.c, but with memory leaks in the error paths), clearly showing we have an issue. Update the v4l2_async_notifier_add_subdev() documentation to clearly state the allocation requirement. Whether this will be enough to avoid new offending code isn't certain, but it's a good first step nonetheless.
