title: Rockchip 2D raster graphic acceleration controller (RGA)

description:
  RGA is a standalone 2D raster graphic acceleration unit. It accelerates 2D
  graphics operations, such as point/line drawing, image scaling, rotation,
  BitBLT, alpha blending and image blur/sharpness. There exist many versions
  of this unit that differ in the supported inputs/output formats,
  the attached IOMMU and the supported operations on the input. As some SoCs
  include multiple RGA units with different versions, a more specific
  compatible name to differentiate the concrete unit is used for them.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
