The tuning request coming in from userspace is already center adjusted, so we should not adjust to center (+1.75mhz) within the driver. Signed-off-by:

cx25840_read4 reads a little-endian 32-bit value whereas cx25840_write4 writes the 32-bit value as big-endian. Convert write4 to use little-endian as well (that's the correct endianness). Signed-off-by:

After this patch, the order of the functions will be the same as before the patch converting the driver to user video_ioctl2. This makes easier to diff between the previous version and the newer one. Signed-off-by: -

ivtv-yuv code clean up & reformat. Includes minor changes to some debug lines. Also fixes a bug found during the reformatting, which would cause the incorrect amount of yuv data to be sent to the card if source cropping coordinates were used. Apart from the bug-fix, there should be no functional difference to the previous version. Signed-off-by:

The driver was incorrectly reporting that it supported YUV 4:2:2 output, when it is actually YUV 4:2:0. Though I believe the hardware can be pushed to 4:2:2, we don't currently support that. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

To reduce the number of display register accesses, the yuv code keeps track of the current video settings. Should there be a change in any single parameter, it will update the associated display registers to ensure everything is displayed correctly. The existing check also looks at the field order for the video. This is not required, since field reversal does not require any display register changes. This patch removes the field order from the check. Signed-off-by:

Inadvertently missed a line when converting code to new hardware buffering method. In some circumstances, this would lead to a frame being displayed using parameters belonging to another frame. Signed-off-by:

ivtv_yuv_prep_frame is split in smaller code blocks. Modified yuv buffer handling on the PVR350 itself. We now cycle through all 8 hardware buffers. With this patch in place, driver behaviour should remain unchanged from the existing release. Signed-off-by:

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. Signed-off-by:

pvrusb2: Eliminate use of volatile in pipeline control state variables. These were all cases of paranoia; upon further review the overall mechanism employed here should not require use of volatile. This had originally been done out of paranoia, and I have since been convinced that the paranoia is not required. Signed-off-by:

This changeset allows the pvrusb2 driver to operate a new device type ("GOTVIEW USB2.0 DVD2"). Changes amount to defining a new routing scheme for the device and adding appropriate table entries into pvrusb2-devattr.c. Signed-off-by: -

The pvrusb2 driver has been successfully recovering from a crashed encoder now for over 2 years. I think it's time to reduce the perceived severity of the warning message. While I'd still very much like to stop these crashes, the recovery logic is solid enough that the problem is effectively benign. No point in panicing the users over it. Signed-off-by:

For Hauppauge 24xxx devices, the IR receiver is a custom piece of logic that is very specific to the device. The pvrusb2 driver can virtualize this to make it look like a more normal IR receiver found in other Hauppauge devices. The decision of whether or not to enable this virtualization however is a device-specific attribute, thus this changeset. Signed-off-by:

The exact routing of video and audio signals within a device is a device-specific attribute. Hauppauge devices do it one way; other types of device may route things differently. Unfortunately it is rather impractical to define chip-specific routing at the device attribute level, so instead what happens here is that "schemes" are defined. Each chip level interface implements its part of a given scheme and the scheme as a whole is made into a device specific attribute controlled via a table entry in pvrusb2-devattr.c. The only scheme defined here is for Hauppauge devices, but clearly this opens the door for other possibilities to follow. Signed-off-by:
