Jolla Brings Wayland Atop Android GPU Drivers
Jolla, the start-up company built around former Nokia N9 engineers developing the Sailfish OS for mobile phones, might be dating Wayland. Jolla's Chief Research Engineer has made it possible to run Wayland atop Android GPU drivers. Additionally, it's being done with glibc rather than Android's Bionic libc derivative.
Carsten Munk, the Chief Research Engineer at Jolla, has been working on a solution to enable the use of Wayland on top of Android hardware, particularly with its GPU drivers. However, as part of it, for the operating system to not depend upon Google's Bionic libc library.
Right now the patches aren't out in the wild but Munk is planning on putting them out under LGPLv2.1. He sees this work as potentially benefiting not only the Sailfish OS but also OpenWebOS, Qt, KDE, GNOME, Hawaii, Nemo, Mer, EFL, etc. The code to this point is at a stage of being able to handle a QML compositor on top of Wayland while rendering to Qualcomm's GPU Android drivers.
first blog post he documents at a low-level all of the different components and his experience in working with them. The second yet-to-be-posted blog entry will cover his actual implementation for achieving Wayland on Android GPU drivers. Until then, he's shared this video of Wayland on Android GPU drivers and using libhybis:
This is rather interesting work. Canonical's Mir Display Server can also run with Android graphics drivers. Canonical's reasonings for supporting Android drivers with Mir were much the same reason with device manufacturers largely only caring about Android. Carsten's work though does go to show the adaptability of Wayland. It's been looking like Jolla would use Wayland for Sailfish OS and with today's information, the situation is still looking positive in that direction.
