media: vsp1: Add VSPX support

2025-06-18T07:20:47Z

Add support for VSPX, a specialized version of the VSP2 that transfers data to the ISP. The VSPX is composed of two RPF units to read data from external memory and an IIF instance that performs transfer towards the ISP. The VSPX is supported through a newly introduced vsp1_vspx.c file that exposes two interfaces: vsp1_vspx interface, declared in vsp1_vspx.h for the vsp1 core to initialize and cleanup the VSPX, and a vsp1_isp interface, declared in include/media/vsp1.h for the ISP driver to control the VSPX operations.

media: renesas: vsp1: Expose color space through the DRM API

2025-05-02T08:16:44Z

Now that the VSP1 driver supports color spaces, expose them through the API used by the DU driver. This allows configuring the YCbCr encoding and quantization used by each plane, ensuring correct color rendering.

media: vsp1: Add premultiplied alpha support

2022-09-07T20:48:39Z

To support DRM blend mode in R-Car DU driver, we must be able to pass a plane with the premultiplied alpha. Adding a new property to vsp1_du_atomic_config allows the R-Car DU driver to pass the premultiplied alpha plane.

media: vsp1: drm: Implement writeback support

2019-03-18T15:24:14Z

Extend the vsp1_du_atomic_flush() API with writeback support by adding format, pitch and memory addresses of the writeback framebuffer. Writeback completion is reported through the existing frame completion callback with a new VSP1_DU_STATUS_WRITEBACK status flag.

media: vsp1: drm: Extend frame completion API to the DU driver

2019-03-18T15:24:09Z

The VSP1 driver will need to pass extra flags to the DU through the frame completion API. Replace the completed bool flag by a bitmask to support this. Signed-off-by: Laurent Pinchart Reviewed-by: Kieran Bingham Reviewed-by: Mauro Carvalho Chehab

media: vsp1: Fix YCbCr planar formats pitch calculation

2018-09-17T18:51:43Z

YCbCr planar formats can have different pitch values for the luma and chroma planes. This isn't taken into account in the driver. Fix it. Based on a BSP patch from Koji Matsuoka .

2018-08-03T20:02:27Z

Calculate the top and bottom fields for the interlaced frames and utilise the extended display list command feature to implement the auto-field operations. This allows the DU to update the VSP2 registers dynamically based upon the currently processing field.

Add a parameter (in the form of a structure to ease future API extensions) to the VSP atomic flush handler to pass CRC source configuration, and pass the CRC value to the completion callback.
