Move tuners to common/tuners There were several issues in the past, caused by the hybrid tuner design, since now, the same tuner can be used by drivers/media/dvb and drivers/media/video. This patch moves those common tuners into a common dir. It also moves saa7146 driver into drivers/media/video, where other hybrid drivers are placed. Kconfig items were rearranged, to split V4L/DVB core from their drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-04-20 Fix VIDIOCGAP corruption in ivtvMauro Carvalho Chehab
From: Alan Cox <alan@lxorguk.ukuu.org.uk> Frank Bennett reported that ivtv was causing skype to crash. With help from one of their developers he showed it was a kernel problem. VIDIOCGCAP copies a name into a fixed length buffer - ivtv uses names that are too long and does not truncate them so corrupts a few bytes of the app data area. Possibly the names also want trimming but for now this should fix the corruption case.

2008-02-21ivtv: yuv framebuffer trackingHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> 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. Signed-off-by: Ian Armstrong <ian@iarmst.demon.co.uk> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-11-05ivtv: Initial merge of video48 yuv handling into the IVTV_IOC_DMA_FRAME ↵Hans Verkuil
framework From: Ian Armstrong <ian@iarmst.demon.co.uk> 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.
