Hmm weird. I was helping Pranith with debugging one of his aarch64 guest setups under TCG and it seemed to be loosing IRQs, I could see level=1 breakpoints being hit in qemu_set_irq but no delivery of the IRQ to the CPU. Unfortunately I had to head home before we got to the bottom of it but I wonder if it is related. As far as the core code is concerned IRQ updates should be protected by the BQL. > > I'll post the palcode update once the mttcg patch set is merged. > > > r~ Good stuff ;-) -- Alex Bennée
