[v2,0/3] Add Rockchip VPU JPEG encoder

Message

Ezequiel Garcia Aug. 1, 2018, 9:07 p.m. UTC

This series adds support for JPEG encoding via the VPU block
present in Rockchip platforms. Currently, support for RK3288
and RK3399 is included.

The hardware produces a Raw JPEG format (i.e. works as a
JPEG accelerator). It requires quantization tables provided
by the application, and uses standard huffman tables,
as recommended by the JPEG specification.

In order to support this, the series introduces a new pixel format,
and a new pair of controls, V4L2_CID_JPEG_{LUMA,CHROMA}_QUANTIZATION
allowing userspace to specify the quantization tables.

Userspace is then responsible to add the required headers
and tables to the produced raw payload, to produce a JPEG image.
