Using TrustZone would be a great way to reduce overhead, but as you guessed, I am currently targeting the arm926EJ-S core, which is ISA ARMv5 without any TrustZone support. The reason being that it is the one emulated by QEMU. Even arm1136, which is the core in the G1 developer phone doesn't have the TrustZones. Which ways to use ARMv6 and ARMv7 features to optimize performance will hopefully occupy starting January :) /Christoffer On Mon, Nov 23, 2009 at 3:52 PM, Hollis Blanchard <hollis at penguinppc.org> wrote: > Why aren't you using TrustZone, a.k.a.
