The same applies to migration: keep our mitts off these registers unless the device is supposed to be on. Does not impact backwards compatibility for the AHCI device. == For convenience, this branch is available at: https://github.com/jnsnow/qemu.git branch ahci-iommu https://github.com/jnsnow/qemu/tree/ahci-iommu This version is tagged ahci-iommu-v1: https://github.com/jnsnow/qemu/releases/tag/ahci-iommu-v1 == John Snow (1): ahci: do not remap clb/fis unconditionally hw/ide/ahci.c | 88 ++++++++++++++++++++++++++++++++++++++++++----------------- 1 file changed, 63 insertions(+), 25 deletions(-) -- 2.1.0
