Hello, I have been playing with your tests for a while and I cannot seem to get them to work all right. When I run them disabling kvm on the arm-run script, they do work, but when I run them with kvm enabled they fail. This is my output: ./arm-run arm/boot.flat -smp 1 -m 256 -append 'info 0x10000000 0x1000' qemu-system-arm -device virtio-testdev -display none -serial stdio -M virt -cpu cortex-a15 -enable-kvm -kernel arm/boot.flat -smp 1 -m 256 -append info 0x10000000 0x1000 kvm [1252]: load/store instruction decoding not implemented error: kvm run failed Function not implemented ./arm-run: line 16: 1251 Aborted $command "$@" Return value from qemu: 134 FAIL boot_info ./arm-run arm/boot.flat -smp 1 -append 'vectors' qemu-system-arm -device virtio-testdev -display none -serial stdio -M virt -cpu cortex-a15 -enable-kvm -kernel arm/boot.flat -smp 1 -append vectors kvm [1257]: load/store instruction decoding not implemented error: kvm run failed Function not implemented ./arm-run: line 16: 1256 Aborted $command "$@" Return value from qemu: 134 FAIL boot_vectors I am using FastModels Model Debugger version 8.2.028, with a model of this characteristics: Model: ------ Model name: ARM_Cortex-A15 Instance: cluster.cpu0 Using CADI 2.0 interface revision 0. Version: 8.2.72 Generated by Core Generator: No Needs SimGen License: No running the latest stable linux release and qemu-devel's latest qemu with the patches indicated here https://lists.gnu.org/archive/html/qemu-devel/2013-10/msg02428.html plus > [1] http://lists.nongnu.org/archive/html/qemu-devel/2013-10/msg01815.html I tested the instalation by running a linux with the same setup using this call: qemu-system-arm \ -display none \ -enable-kvm \ -kernel zImage\ -m 128 -M virt -cpu cortex-a15 \ -drive if=none,file=linux.img,id=fs \ -device virtio-blk-device,drive=fs As I said, the tests pass if the kvm is not enabled and fail otherwise. I have added a few printfs for debugging and I can tell that the code in boot.c runs ok, but then when virtio_testdev is called (from virtio_testdev_exit) the execution throws an exception (more specifically the line *tdp++ = cpu_to_le32(va_arg(va, unsigned)); inside the first while. I am not used to sending emails to this kind of list, so I don't know if I am being too specific, too little or maybe not even giving the right information. Please tell me what else you need and if you can help me solve this problem. Thank you very much, María. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
