This patch set introduces a more generic renderonly driver library based on "[RFC] tegra: Initial support" [0] from Thierry Reding.
I am re-using almost all of the existing code and extended it with a struct renderonly_ops, which defines the wanted behavior for the target hardware. There are two different usage patterns, which are supported. 1) Set a required tiling on the scanout buffer (tegra) 2) Use an intermediate buffer and blit to dumb buffer (imx) The setup of struct renderonly_ops happens in winsys. So it is possible to support different configurations for different versions of an IP core, which are using the same KMS driver. I really hope to get some feedback as the bare metal EGL use case is important as not everyone runs a compositor, which understands rendernodes. This patch set was successfully tested on tegra and imx-drm (etnaviv based) and runs kmscube.
