This change allows the IDX stream to be started and stopped as any other stream even though it has no associated device node. This is needed for cx18 driver internal use. Also always tell the CX23418 to generate index entries when an analog capture starts and the IDX stream has had buffers allocated (i.e. is enabled). Signed-off-by:

Fix a long standing memory leak of stream buffers for streams that did not have a struct video_device allocated: namely the TS and IDX streams. Signed-off-by:

Update the module options related to INDEX stream buffer allocation. A single CX2341[5678] index entry is only 24 bytes. Large buffers for the IDX stream will prevent the CX23418 from transferring index data over at all. Buffers of around 1.5 kB or 64 index entries seem to be just fine. We'll default to 63 buffers/MDLs as that is the firmware limit per stream and IDX stream buffers are not high rate. There is no reason on earth to allocate the previous 1 MB default of buffer space for the IDX stream. This is in anticipation of implementing the G_ENC_INDEX ioctl() in the cx18 driver.

After taking a look at the driver's history and doing some tests with DVB and ISDB-T, it was noticed that the stats were incomplete, for ISDB-T, and weren't working for DVB. Fixed the code and added a debug code to print the complete stats at dmesg. This debug is useful to improve the stats of this driver. Signed-off-by: -

Based on a patch originally written by Michael Krufky <mkrufky@linuxtv.org> for a preliminar S2API spec. The patch were ported to the S2API and had the ISDB-T API additions to honor the auto mode, while keep allowing manual tuning. Tested with both the original dvb-apps and the new dvb-apps-isdbt scan, that uses a different channel.conf and uses S2API with ISDB-T extensions. Thanks-to: Michael Krufky <mkrufky@linuxtv.org> for his first version Signed-off-by: -

Siano series of patches seemed to cause a regression on reporting DTV statistics. Due to that, signal indication weren't received, preventing applications like scan to work. Tested with ISDB-T signals and got the same scan result as with a dib0700/dib8000 device. Signed-off-by: -

For some unknown reason, on a MacBookPro5,3 the iSight sometimes report a different video format GUID. This patch add the other (wrong) GUID to the format table, making the iSight work always w/o other problems.

The quirks module parameter is or'ed with the built-in quirks for the device being probed. This make it impossible to disable a built-in quirk without recompiling the driver. Replace the built-in quirks with the quirks module parameter instead of or'ing the values. Signed-off-by:

The realtime clock provided by do_gettimeofday() is affected by time jumps caused by NTP or DST. Furthermore, preliminary investigation showed that SMP systems the realtime clock is based on the CPU TSC, and those could get slightly out of sync, resulting in jitter in the timestamps depending on which processor handles the USB interrupts. Instead of the realtime clock, use a monotonic high resolution clock to timestamp the buffer. As this could in theory introduce a regression with some userspace applications expecting a realtime clock timestamp, add a module parameter to switch back to the realtime clock. Thanks to Paulo Assis for pointing out and investigating the issue. Signed-off-by:
