Can it be that qemu (-system-sparc in my case, but I guess it's more or less similar on all platforms) reacts to irqs slower than a real hardware due to tcg optimizations?
I see one test pattern which fails on qemu: <cause an interrupt> nop * N <check whether the interrupt happened> What I observe is that the proper interrupt does take a place, but after the check, so no-one expects it anymore. Is there a way to reduce the interrupt latency? Or maybe there is a good substitute to a nop*N, so that irq would definitely get through in the mean time? Artyom
