Would be nice to get some of them in 11.2. Can be found at: https://github.com/eauger/qemu/tree/arm-cpu-model-v11-prereq-v4 History: v3 -> v4: addressed all comments from Peter - remove static local variable and keep on relying on TARGET_NONE check - add error_free on finalize - dont error_append_hint anymore - store the probe error in ARMHostCPUFeatures - add doc comment kvm_arm_get_host_cpu_features to emphasize that on failure TARGET_NONE is set and an error is set v2 -> v3: - added target/arm: Directly store cpu probe failure error (Peter) - target/arm/kvm: Pass an error handle to kvm_arm_create_scratch_host_vcpu v1 -> v2: - Fixed comma in target/ppc/kvm.c - Improved commit description and comment in last patch - collected R-b's (thanks!)
