Hi, while reworking the ARM vGIC emulation layer to use the kvm_io_bus framework, I wonder why the whole KVM MMIO handling always passes the pointer to struct kvm_run along with the struct kvm_vcpu pointer. As kvm_run is a member of kvm_vcpu, the vcpu alone should be sufficient, right? Also I see the very top of the call chain is effectively: kvm_arch_vcpu_ioctl_run(vcpu, vcpu->run); So is that just legacy code still lingering around from the dawn of time and nobody dared to rework this or is there a particular reason for doing so? I am asking because I lack the kvm_run pointer in the MMIO handler, so I just use vcpu->run and I wonder if there are potential issues in doing so. Cheers, Andre. _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
