Linux Plumbers Conf 2014

One Line Summary

Abstract

This presentation will focus on the issues we faced while porting Android’s IPC mechanisms, binder and ashmem, to 64-bit. We will discuss about Android’s compact layer, support for 32-bit applications running on 64-bit kernels, as well as 64-bit ABI changes. We will also propose a path for replacing Binder, Android’s IPC.

  Biography

  I am Software Engineer working for ARM as part of the Android team. In the past few years I have been involved on a couple of Android subsystems from Ashmem and Binder to libc, Dalvik and ART. I have been actively involved in the ARM64 Android bootstrap and previously I have been maintaining the ARM Versatile Express Android ports.

  At roots I have an electronics background, graduated the Polytechnic University of Bucharest and a master at Bristol University.

  Ask me about:

  • ARM
  • Binder
  • Bionic
  • Art
  • Android
  • OpenCV (though a bit rusty now)
