Looks like product datasheets for tuners containing STB0899 are suggesting specification for min. symbol rate of 2MS/s. Some specs found here, all suggesting 2MS/s for min. symbol rate: Comtech DVBS2-6899 http://comtech.sg1002.myweb.hinet.net/pdf/dvbs2-6899.pdf TechniSat SkyStar HD2 http://www.scaistar.com/skystar2/skystarhd2.htm Azurewave AD-SP400 http://www.pulsat.com/products/AzureWave-AD%252dSP400-High-Definition-PC-Card.html New patch: This makes minimum symbol rate driver capabilities on par with some accessible datasheet specifications*, and allows tuning on linux to transponders that have symbol rate between 2000000-5000000, too. Patch was tested successfully on Eutelsat 16A transponders that became reachable with it (2000000 < symbol rate < 5000000): * DVB/S 12507050 V 2532000 3/4 * DVB/S2 12574000 V 4355000 3/4 8PSK * DVB/S 12593000 V 2500000 2/3 * DVB/S 12596940 V 2848000 2/3 * DVB/S 12600750 V 2500000 1/2 * DVB/S 12675590 H 4248000 3/4 (*) Datasheet: http://comtech.sg1002.myweb.hinet.net/pdf/dvbs2-6899.pdf Maximum Symbol Rate QPSK/LDPC/PCH: 20-30Mbps 8PSK/LDPC/BCH: 10-30Mbps DVB: 2-45Mbps ^--------- min. symbol rate Signed-off-by:Zoran Turalija <zoran.turalija@gmail.com> Signed-off-by:

Throughout the zig-zag-implementations, inversion is taken into account when reading and writing the CFR register, which contains the derotator frequency. As swapping IQ signals changes the sign of that register for example, the idea is to compensate that sign change by multiplying the register value with the inversion enum value. The current enum values 0 and 1 for IQ_SWAP_OFF and IQ_SWAP_ON don't work in the case IQ_SWAP_OFF, due to the multiplication by zero (I've only found a single device which actually uses IQ_SWAP_OFF in it's config). I've changed the enum values to +1 and -1 to accommodate to the intended usage. Signed-off-by:

It seems that current inversion handling addresses only the signal routing on the PCB, i. e. IQ signals are either swapped or not. But when the device is operated in a Satellite Channel Router (SCR) environment, an additional inversion is required due to the way how the SCR works. Therefore it makes sense to me to always enable auto inversion handling and drop the enum value IQ_SWAP_AUTO. Signed-off-by:

Contrary to the chip's specs, the register's value is signed, so we need to sign extend the value before using it in calculations like when determining the offset frequency. Signed-off-by:

Maintaining the users count using an atomic variable makes sure that access to the counter won't be racy, but doesn't serialize access to the operations protected by the counter. This creates a race condition that could result in the status URB being submitted multiple times. Use a mutex to protect the users count and serialize access to the status start and stop operations.

If we just declare the job finished here while the CODA is still running, the call to v4l2_m2m_ctx_release in coda_release, which is supposed to wait for a running job to finish, will return immediately and free memory that the CODA is still using. Just set the 'aborting' flag and let coda_irq_handler deal with it. Signed-off-by:

Not only do we need to wait for job completion when we want to call a command on the CODA in start/stop_streaming, we also need to make sure that a new job doesn't start before the command finished. Use a mutex to lock the coda command handling. On timeout, the device_run job must be marked as finished and the mutex released, as otherwise coda_release will block. Signed-off-by:

This patch adds a list of supported codecs per device type which is used to determine the allowed pixel formats and maximum frame sizes depending on the possible codecs. It allows frame sizes larger than 720 x 576 on CODA7 and adds support for the YVU420 (planar YUV 4:2:0 with switched Cb and Cr) format. Other uncompressed formats that could be added in the future are the chroma interleaved NV12 and NV21 formats and the multiplanar variants YUV420M, YVU420M, NV12M, and NV21M. Further, rawstreamon is renamed to streamon_out and compstreamon is renamed to streamon_cap in preparation for decoding support. The maximum encoded frame buffer size is increased to 1 MiB. Instead of tracking inst_type and codec across S_FMT calls, set the codec and inst_type in start_streaming. Signed-off-by:

The orig code will release all the resources if v4l2_device_register() failed and return 0. But what we need in this case is to return an negative error code to let the caller known we are failed.
