[Qemu-devel] [PATCH 12/13] spapr/xics: ignore the lower 4K in the IRQ number space

2019-01-07 Thread Cédric Le Goater
The IRQ number space of the XIVE and XICS interrupt mode are aligned when using the dual interrupt mode for the machine. This means that the ICS offset is set to zero in QEMU and that the KVM XICS device should be informed of this new value. Unfortunately, there is now way to do so and KVM still ma
