* [media] v4l: ti-vpe: create a color space converter block libraryArchit Taneja2014-01-07
| | | | | | | | | | | | | | | | | | | VPE and VIP IPs in DAR7x contain a color space converter(CSC) sub block. Create a library which will perform CSC related configurations and hold CSC register definitions. The functions provided by this library will be called by the vpe and vip drivers using a csc_data handle. The vpe_dev holds the csc_data handle. The handle represents an instance of the CSC hardware, and the vpe driver uses it to access the CSC register offsets or helper functions to configure these registers. The CSC register offsets are now relative to the CSC block itself, so we need to use the macro GET_OFFSET_TOP to get the CSC register offset relative to the VPE IP in the vpe driver.

* [media] v4l: ti-vpe: enable basic scaler supportArchit Taneja2014-01-07
| | | | | | | | | | | | | | | | | | | | | | | | Add the required SC register configurations which lets us perform linear scaling for the supported range of horizontal and vertical scaling ratios. The horizontal scaler performs polyphase scaling using it's 8 tap 32 phase filter, decimation is performed when downscaling passes beyond 2x or 4x. The vertical scaler performs polyphase scaling using it's 5 tap 32 phase filter, it switches to a simpler form of scaling using the running average filter when the downscale ratio is more than 4x. Many of the SC features like peaking, trimming and non-linear scaling aren't implemented for now. Only the minimal register fields required for basic scaling operation are configured. The function to configure SC registers takes the sc_data handle, the source and destination widths and heights, and the scaler address data block offsets for the current context so that they can be configured.

* [media] v4l: ti-vpe: make vpe driver load scaler coefficientsArchit Taneja2014-01-07
| | | | | | | | | | | | | | | | | | | | | Make the driver allocate dma buffers to store horizontal and scaler coeffs. Use the scaler library api to choose and copy scaler coefficients to a the above buffers based on the scaling ratio. Since the SC block comes after the de-interlacer, make sure that the source height is doubled if de-interlacer was used. These buffers now need to be used by VPDMA to load the coefficients into the SRAM within SC. In device_run, add configuration descriptors which have payloads pointing to the scaler coefficients in memory. Use the members in sc_data handle to prevent addition of these descriptors if there isn't a need to re-load coefficients into SC. This comes helps unnecessary re-loading of the coefficients when we switch back and forth between vpe contexts.

* [media] v4l: ti-vpe: support loading of scaler coefficientsArchit Taneja2014-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SC block in VPE/VIP contains a SRAM within it. This internal memory requires to be loaded with appropriate scaler coefficients from a contiguous block of memory through VPDMA. The horizontal and vertical scaler each require 2 sets of scaler coefficients for luma and chroma scaling. The horizontal polyphase scaler requires coefficients for a 32 phase and 8 tap filter. Similarly, the vertical scaler requires coefficients for a 5 tap filter. The choice of the scaler coefficients depends on the scaling ratio. Add coefficient tables for different scaling ratios in sc_coeffs.h. In the case of horizontal downscaling, we need to consider the change in ratio caused by decimation performed by the horizontal scaler. In order to load the scaler coefficients via VPDMA, a configuration descriptor is used in block mode. The payload for the descriptor is the scaler coefficients copied to memory. Coefficients for each phase have to be placed in memory in a particular order understood by the scaler hardware. The choice of the scaler coefficients, and the loading of the coefficients from our tables to a contiguous buffer is managed by the functions sc_set_hs_coefficients and sc_set_vs_coefficients. The sc_data handle is now added with some parameters to describe the state of the coefficients loaded in the SC block. 'loaded_coeff_h' and 'loaded_coeff_v' hold the address of the last dma buffer which was used by VPDMA to copy coefficients. This information can be used by a vpe mem-to-mem context to decide whether it should load coefficients or not. 'hs_index' and 'vs_index' provide some optimization by preventing loading of coefficients if the scaling ratio didn't change between 2 contexts. 'load_coeff_h' and 'load_coeff_v' tell the vpe/vip driver whether we need to load the coefficients through VPDMA or not.

In order for VPDMA to configure registers, it requires it's offset from the top level VPE module. A macro called GET_OFFSET_TOP is added to return the offset of the register relative to the VPE IP.

* [media] v4l2: move tracepoints to video_usercopyHans Verkuil2014-01-07
| | | | | | | | | | | | | | | | | The (d)qbuf ioctls were traced in the low-level v4l2 ioctl function. The trace was outside the serialization lock, so that can affect the usefulness of the timing. In addition, the __user pointer was expected instead of a proper kernel pointer. By moving the tracepoints to video_usercopy we ensure that the trace calls use the correct kernel pointer, and that it happens right after the ioctl call to the driver, so certainly inside the serialization lock. In addition, we only trace if the call was successful.

| | | | | | | | | | | | | | | | | | Both the PAL and NTSC standards are interlaced where a frame consist of two fields. Total number of lines in a frame in both systems are an odd number so the two fields will have different length. In the 625 line standard ("PAL") the odd field of the frame is transmitted first, while in the 525 standard ("NTSC") the even field is transmitted first. This adds the possibility to change output config between the fields and standards. This setting will reduce the "format-jitter" on the signal sent by the pixelport moving the difference between the fields to vertical front/back-porch only.
