FakeDisplayStack is a series of drivers provided as standalone device nodes (device tree) independent from the system display coordinator and display engine drivers.
This includes a fake display driver, a fake display coordinator driver and a fake sysmem Allocator driver.
fake-display is a display engine driver that allows clients to import and present images and capture the current displayed contents.
The fake-display driver exports structured display configuration and state using the Inspect API only for developer debugging purpose. Tests must not depend on the inspection contents from driver host or components providing fake-display.
