The service_set field was used in saa7115 and cx25840 to determine whether raw or sliced VBI was desired. This is incorrect since it is perfectly valid to select sliced VBI with a service_set of 0.

2008-04-24V4L/DVB (7243): ivtv: yuv framebuffer trackingIan Armstrong
The existing yuv code limits output to the display area occupied by the framebuffer. This patch allows the yuv output to be 'detached' via V4L2_FBUF_FLAG_OVERLAY. By default, the yuv output window will be restricted to the framebuffer dimensions and the output position is relative to the top left corner of the framebuffer. This matches the behaviour of previous versions. If V4L2_FBUF_FLAG_OVERLAY is cleared, the yuv output will no longer be linked to the framebuffer. The maximum dimensions are either 720x576 or 720x480 depending on the current broadcast standard, with the output position relative to the top left corner of the display. The framebuffer itself can be resized, moved and panned without affecting the yuv output.

2008-01-25V4L/DVB (6717): ivtv: Initial merge of video48 yuv handling into the ↵Ian Armstrong
IVTV_IOC_DMA_FRAME framework Previously, all yuv data written to /dev/video48 had only basic support with no double buffering to avoid display tearing. With this patch, yuv frames written to video48 are now handled by the existing IVTV_IOC_DMA_FRAME framework. As such, the frames are hardware buffered to avoid tearing, and honour scaling mode & field order options. Unlike the proprietary IVTV_IOC_DMA_FRAME ioctl, all parameters are controlled by the V4L2 API. Due to mpeg & yuv output restrictions being different, their V4L2 output controls have been separated. To control the yuv output, the V4L2 calls must be done via video48. If the ivtvfb module is loaded, there will be one side effect to this merge. The yuv output window will be constrained to the visible framebuffer area. In the event that a virtual framebuffer size is being used, the limit to the output size will be the virtual dimensions, but only the portion that falls within the currently visible area of the framebuffer will be shown. Like the IVTV_IOC_DMA_FRAME ioctl, the supplied frames must be padded to 720 pixels wide. However the height must only be padded up the nearest multiple of 32. This would mean an image of 102 lines must be padded to 128. As long as the true source image size is given, the padding will not be visible in the final output.

2008-01-25V4L/DVB (6716): ivtv: yuv interlace mode changeIan Armstrong
Interlace mode selection code moved into the frame setup phase, so it's now run before the frame is loaded into a hardware buffer. Given that it can affect how a new frame is displayed, it was a bit stupid running it after the frame was already visible. A few stray interlace related variables which were linked to individual frames have now been moved into the yuv_frame_info struct. This means that all variables linked to a specific frame are in the same place & not scattered. Minor code reformatting in areas touched by the above changes.

2008-01-25V4L/DVB (6712): ivtv: ivtv yuv stream handling changeIan Armstrong
Currently the yuv output stream buffer is divided into blocks whose size depend on the broadcast standard selected during the driver init phase. However, the standard can be changed after the init phase. This effectively breaks the yuv output stream handler, since it relies on the different yuv planes being block aligned. This patch changes the setup, so that the block size is always the same. The decoder dma function has been modified to cope with the fact that the second yuv plane may no longer be block aligned. The start of the yuv frame must still be at the beginning of a block, so the stream write function has also been modified to ensure this is always true. Also, the stream write function will now initiate a yuv dma transfer as soon as a full frame is ready. It will not wait until the current write request has completed, or the stream buffer becomes full.

This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke. Instead of increasing the header file spider web I choose to include <linux/scatterlist.h> directly into the affectes files.

2007-10-09V4L/DVB (6047): ivtv: Fix scatter/gather DMA timeoutsHans Verkuil
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.

2007-10-09V4L/DVB (5973): ivtv: attach yuv field order to each frameIan Armstrong
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.
