I'm trying to convert my EGL code to use the virtual framebuffer on Android 4.4 and I'm looking for the symbols fbGetDisplayByIndex and fbCreateWindow, but I don't see them in the Vivante EGL libraries. I pulled libEGL_VIVANTE.so and libGLESv2_VIVANTE.so from the demo BSP and neither one has these functions. I also pulled the 5.0 BSP and tried the same (newer versions won't work with 4.4 due to linker/loader incompatibilities) with no luck.
Is there a separate library that contains these functions, or am I looking at the wrong version of the libraries? When I search "GPU SDK" and similar terms in the download center, I find an SDK that contains documents and very nice demo code, but no libraries. It's not clear to me where I should be getting the libs and headers to support this feature.
