Detailed Description

Raster (software) implementation of RDevice.

RRSDevice is a CPU software-rendering device owned by RRSCore, and can be obtained from an RDevice via asRS(). Depending on the platform it wraps a Wayland connection (no DRM node), a DRM node (opened for dumb-buffer allocation and GBM), or a pure offscreen software device. Its supported texture/render formats are the intersection of the Skia- and DRM-supported formats, always with linear layout.

Member Function Documentation

core()

RRSCore & core ( )

inlinenoexcept

Returns the owning Raster core.

wait()

void wait ( )

inlineoverridevirtualnoexcept

No-op for the Raster backend.

Software rendering is synchronous, so there is nothing to wait on.
