DEFINE_VMAPPLE_MACHINE_AS_LATEST(10, 0)
This change enables the new conditional interrupt mapping support property on the vmapple machine type's integrated XHCI controller using compat_props. The macOS guest driver attempts to use event rings 1 and 2 on the XHCI controller, despite there being only one (PCI pin) interrupt channel available. With conditional interrupt mapping enabled, the XHCI controller will only schedule events on interrupter 0 in PCI pin mode. Signed-off-by: Phil Dennis-Jordan <phil@philjordan.eu> --- v2: * Set the "conditional-intr-mapping" property via compat_props, not directly on the created XHCI controller object. hw/vmapple/vmapple.c | 11 +++++++++++ 1 file changed, 11 insertions(+)
