------- Comment From [email protected] 2017-11-30 14:15 EDT------- I was talking to Kleber and he's getting some errors like:
KVM: Failed to create TCE64 table for liobn 0x71000002 KVM: Failed to create TCE64 table for liobn 0x80000000 TCE is responsible to translate IO address to physical address. QEMU checks if KVM supports TCE64 (64-bit window size) capability before creating it. https://github.com/torvalds/linux/blob/master/Documentation/virtual/kvm/api.txt#L2985 [QEMU] target/ppc/kvm.c : kvmppc_create_spapr_tce ... if (cap_spapr_tce_64) { struct kvm_create_spapr_tce_64 args = { .liobn = liobn, .page_shift = page_shift, .offset = bus_offset >> page_shift, .size = nb_table, .flags = 0 }; fd = kvm_vm_ioctl(kvm_state, KVM_CREATE_SPAPR_TCE_64, &args); if (fd < 0) { fprintf(stderr, "KVM: Failed to create TCE64 table for liobn 0x%x\n", liobn); return NULL; } } ... I'm now investigating why that failure happened. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1733864 Title: kernel 4.10.0-40 is hanging with a CPU soft lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1733864/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
