Only thing that comes to mind is whether it might make sense to hierarchically make Broadwell the parent type of Broadwell-noTSX, to avoid duplication. But then again we already have a lot of it. ;) Regards, Andreas > hw/i386/pc_piix.c | 4 --- > hw/i386/pc_q35.c | 4 --- > target-i386/cpu.c | 74 +++++++++++++++++++++++++++++++++++++++++++++++++++++-- > 3 files changed, 72 insertions(+), 10 deletions(-) -- SUSE Linux GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Jane Smithard, Jennifer Guild, Dilip Upmanyu, Graham Norton; HRB 21284 (AG Nürnberg) -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
