So my project requires that i put a trace on a page in booke architecture (i.e removing the read and write privileges of that page) which causes all the instructions that try to read or write to this page to trap under DATA_STORAGE exit where i'm emulating them. Also the same problem appears when i try to use the existing MMIO mechnism since it resumes with the flag RESUME_HOST_NV . And iam saving the register using kvmppc_set_gpr(vcpu,register # ) and the DATA_STORAGE exit is listed in NEED_ESR_MASK -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
