The patch by Intel's Adrian Negreanu allows for Android's fbdev HAL to be used through libhybris with this library being implementing wayland-egl. Libhybris is a compatibility layer for allowing Bionic-based Android libraries/drivers to be loaded by glibc-based Linux systems. Hybris was originally written by a Mer developer who went on to join Jolla. Hybris has since been utilized by Canonical's Ubuntu Touch/Mir and Wayland. Carsten Munk the original libhybris developer had made it possible to run Wayland with Android graphics drivers.
Hybris translates Bionic and Android EGL library calls into glibc and Wayland EGL calls, respectively. The single patch proposed on Friday is to mainline libhybris support for Android's fbdev HAL.
