2007-08-18ivtv: fix VBI reinsertion decodingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - Invalid VBI packets should result in an empty VBI frame, not in an zero-sized frame that causes the reader to incorrectly return a 0 (EOF) value. - PIO completion should not reset the sg_pending_size field. - The DMA offset detection code should be ignored for PIO transfers: it somehow messes up the data on the card and is not needed anyway for PIO.

2007-07-29ivtv: Fix scatter/gather DMA timeoutsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> It turns out that the cx23415/6 DMA engine cannot do scatter/gather DMA reliably. Every so often depending on the phase of the moon and your hardware configuration the cx2341x DMA engine simply chokes on it and you have to reboot to get it working again. This change replaced the scatter/gather DMA by single transfers at a time, where the driver is now responsible for DMA-ing each buffer. UDMA is still done using scatter/gather DMA, that will be fixed soon. Many thanks to Mark Bryars <mark.bryars@etvinteractive.com> for discovering the link between scatter/gather and the DMA timeouts.

2007-07-28ivtv: always steal full frames if out of buffers.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> When there are no more free buffers, then buffers are stolen from the predma queue. Buffers should be stolen from the head of that queue (which is where the most recently added buffers are) and all buffers belonging to a frame should be stolen. Otherwise 'half-frames' would remain in the queue, which leads to ugly playback and complete sync failure for YUV buffers. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-18ivtv: fix handling of INITIALIZE_INPUT fw callHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The CX2341X_ENC_INITIALIZE_INPUT firmware call requires careful handling, otherwise the computer can freeze or the top-third of the screen can start flickering. This patch ensures that CX2341X_ENC_INITIALIZE_INPUT is called at the right time and in the right way. In addition the stop capture handling was improved so that the last pending DMA transfer is also processed. Otherwise this would be the first data that arrived when a new capture was started which is not what you want. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-05ivtv: no need to mute the audio inputHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> When changing channels the audio has to be muted. This is done by calling CX2341X_ENC_MUTE_AUDIO and by muted the audio input. The latter is not necessary and is now removed. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-04ivtv: add AverMedia M116, prepare for userspace Xceive tunerHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - Split Club3D card from Yuan PG600-2, GotView PCI DVD Lite (different composite input) - Add AVerTV MCE 116 Plus (M116) card - Allow Xceive cards to be used without Xceive support - Update Xceive support to latest userspace tuner (still not on by default, pending inclusion of userspace tuner in the kernel). - Use CONFIG_XC3028 rather than HAVE_XC3028: gentree.pl will remove them automatically.

2007-08-03ivtv: attach yuv field order to each frameHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> In the current driver, the field order is global. As soon as it's changed it takes immediate effect. This is a problem when the video changes order mid stream. Although it mostly works okay, the video may judder / flicker. This patch attaches the field order to the frame, so that any buffered frames will not be displayed until the correct field. In the event that the field order is changed mid stream, the driver will ensure that the previous frame is displayed for a minimum of 3 fields. These are the two original fields the frame should have occupied, plus the one extra since the new frame still has to wait for the correct field.

2007-08-03ivtv: prevent yuv register updates from being missedHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> The yuv output code always compares the new frame position & size with those of the previous frame. If they are different, a flag is set to request the yuv output registers be updated when the new frame is displayed. If the incoming frames are delivered too fast, exhausting the buffers, the most recent frame already buffered will be discarded. Unfortunately, any update request will also be discarded. If the new frame matches the size & position of the now discarded frame, the yuv registers are not flagged for update & will remain in their old state. This patch preserves the register update flag in the event that a frame is dropped. Signed-off-by: Ian Armstrong <ian@iarmst.demon.co.uk> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-03ivtv-fb: framebuffer timings no longer locked on module loadHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> Framebuffer timings are currently locked to the video format in use when the module is loaded. If the video format is then changed, the timings returned by the framebuffer will be for the original format. This patch ensures that the timings returned reflect the current video format.

2007-08-03ivtv: prevent vertical overflow of yuv outputHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> When the video standard is changed, there's no guarantee the framebuffer dimensions are still legal. The yuv output code uses these dimensions to calculate the size & position for the video overlay. If the framebuffer dimensions are now illegal, the output may exceed the vertical limit of the display, causing distortion. This patch adds an additional check to ensure the output doesn't exceed the limits for the current video standard, cropping if required.

2007-07-22ivtv: fix TV-out VBI handling, only reset on last close.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> While decoding (MPEG or YUV) is active or when VBI output is in use, then do not clear the VBI output of the saa7127. Only after the last user is gone can we clear it. This fixes the case where playback was stopped, another channel was chosen and playback was restarted, while /dev/vbi16 was used to set the WSS (widescreen) setting. Without this fix the WSS was reset on every stop instead of just keeping the last value. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-07-18ivtv: fix DMA timeout when capturing VBI + another streamHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The VBI DMA is handled in a special way and is marked with a bit. However, that bit was set at the wrong time and could be cleared by mistake if a PCM (or other) DMA request would arrive before the VBI DMA was completed. So on completion of the VBI DMA the driver no longer knew that that DMA transfer was for VBI data. And this in turn caused havoc with the card's DMA engine.
