In KVM ARM/ARM64 one can run cross-endian guset with respect to host kernel. For virtio to work with this we need to make virtio code aware of guest's endianness. This patchset adds the guest endianness determination for KVM ARM/ARM64 and related small fix in KVM ARM64.
V2->V3: - Renamed arm_cpu_virtio_endianness() to arm_cpu_is_big_endian() - Added check for current exception level so that endianness for el0 is determined by looking at sctlr EOE and for others from sctlr EE bit. V1->V2: - Change the patch to be used generically for both ARM and ARM64. - Define TARGET_IS_BIENDIAN for target-arm - Address the review comments received in v1. - Rebased code on top of latest qemu code. V1: - First patch in this series. - http://lists.gnu.org/archive/html/qemu-devel/2014-10/msg03321.html Pranavkumar Sawargaonkar (2): target-arm: KVM64: Get and Sync up guest register state like kvm32. target-arm: Guest cpu endianness determination for virtio KVM ARM/ARM64 target-arm/cpu.c | 24 ++++++++++++++++++++++++ target-arm/cpu.h | 2 ++ target-arm/kvm64.c | 13 ++++++++++++- 3 files changed, 38 insertions(+), 1 deletion(-) -- 1.9.1
