* include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LISTRichard Henderson2024-12-191-1/+0
| | | | | | | | | | | | | | Now that all of the Property arrays are counted, we can remove the terminator object from each array. Update the assertions in device_class_set_props to match. With struct Property being 88 bytes, this was a rather large form of terminator. Saves 30k from qemu-system-aarch64.

* hw/ssi: ibex_spi_host: Clear the interrupt even if disabledAlistair Francis2023-11-071-2/+4
| | | | | | | | | | | | | | | | | | | | We currently don't clear the interrupts if they are disabled. This means that if an interrupt occurs and the guest disables interrupts the QEMU IRQ will remain high. This doesn't immediately affect guests, but if the guest re-enables interrupts it's possible that we will miss an interrupt as it always remains set. Let's update the logic to always call qemu_set_irq() even if the interrupts are disabled to ensure we set the level low. The level will never be high unless interrupts are enabled, so we won't generate interrupts when we shouldn't.
