2011-05-20[media] cx18: Make RF analog TV work for newer HVR-1600 models with silicon ↵Andy Walls
tuners A previous changes which added the newer model HVR-1600's and DTV support for them, neglected to add RF analog TV for them. Fix RF analog TV for the newer HVR-1600's which have a worldwide analog tuner assembly with a TDA18271 tuner and TDA8295 demodulator. Thanks go to Jeff Campbell and Mike Bradley for reproting the problem, and also to Mike Bradley for doing a lot of the legwork to figure out the tuner reset GPIO line, the demodulator I2C address, and that the GPIOs have to be reinitialized after a cardtype switch.

With cmwq, there's no reason to use separate out_work_queue. Drop it and use system_wq instead.

2010-12-29[media] Patch for cx18 module with added support of GoTView PCI DVD3 Hybrid ↵Alexey Chernov
tuner I've got code which adds support of GoTView PCI DVD3 Hybrid tuner in cx18 module and Andy Walls in ivtv mailing-list gave me some advice on making a patch and sending it here. So here's the patch against staging/2.6.37-rc1 branch (the tutorial recommends to include it as plain text but if it's the case I can surely send as an attachment): Several comments on the patch: 1. Both users on the official Gotview forum and support said that PCI DVD3 is very similar to Yuan MPC718 card so the main part of code is taken from Yuan configuration. Some users reported it to work properly. 2. Everything is being initialized correctly including analog, dvb, radio and alsa parts. Analogue part and alsa virtual card is tested by myself using original Gotview card.

2010-12-24media/video: explicitly flush request_module workTejun Heo
Video drivers request submodules using a work during probe and calls flush_scheduled_work() on exit to make sure the work is complete before being unloaded. This patch makes these drivers flush the work directly instead of using flush_scheduled_work(). While at it, relocate request_submodules() call in saa7134_initdev() right right before successful return as in other drivers to avoid failing after the work is scheduled and returning failure without the work still active. This is in preparation for the deprecation of flush_scheduled_work(). Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Mauro Carvalho Chehab <mchehab@infradead.org>

2010-02-26V4L/DVB (13902): cx18: Update MPEG Index stream buffers module option processingAndy Walls
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.

2009-12-05V4L/DVB (13430): cx18: Fix YUV capture so that encoder passes a single frame ↵Andy Walls
per transfer Fix YUV capture such that the encoder will pass one frame per transfer. This will allow the application to maintain frame alignment when a transfer from the encoder is missed due to high system latency in service the CX23418 IRQ. Also force YUV buffer sizes to be specified in multiples of 33.75 kB, the smalled amount of buffer sizes need to store a complete set of HM12 4:2:0 macroblocks specifying 32 lines of the frame. A full 60Hz/525 line screen requires 15 * 33.75 kB per frame and a full 50Hz/625 line screen requires 18 * 33.75 kB per frame so the default buffer size is 3 * 33.75 kB, requiring exactly 5 or 6 buffers per MDL respectively. The bytes needed per frame and hence MDL need not be the bytes in an integer number of buffers. However, if frame artifacts are seen with scaled screen sizes, the YUV buffer size can be set 34 kB (33.75 kB) to get rid of the artifacts at the cost of more copies between the kernel and userspace.
