Hi, cpu_interrupt() doesn't scale well with heterogenous machines because its mask is target specific (defined in target/ARCH/cpu.h).
While it is (often...) used by target-specific hw to notify cpu, there is no restriction to use such target-specific hw in a heterogeneous setup, where it'd still target the same kind of target cpus. The Alpha Typhoon HW is unlikely to be used heterogeneously, but it is the simplest case I found to illustrate how I plan to remove cpu_interrupt() calls from hw/: use the QDev GPIO API. Does that sound good enough? Thanks, Phil.
