From 612f8f074fa1099cf70faf495d46cc647762a031 Mon Sep 17 00:00:00 2001 From: ARM gem5 Developers Date: Fri, 24 Jan 2014 15:29:34 -0600 Subject: arm: Add support for ARMv8 (AArch64 & AArch32) Note: AArch64 and AArch32 interworking is not supported. If you use an AArch64 kernel you are restricted to AArch64 user-mode binaries. This will be addressed in a later patch. Note: Virtualization is only supported in AArch32 mode. This will also be fixed in a later patch.
