One of the reasons why the bg stuff hasn't been re-posted is because the only user currently is the sanitation work (and hopefully maybe scan media soon), which in turn depends on the cache-flushing thing to be picked up (unless someone starts ranting again against wbinvd). And that is in Dave's pmem security series which I'm hoping will be picked up for v6.3 at some point. So I guess we're a while away from the irq thing. I was mostly suggesting sending an mbox-only just to layout the pci_alloc_irq_vectors if we're not using the common table, but per the above this might not be sooner than the pmu or events stuff... >Unused infrastructure tends to rot or not be quite what is >needed. No arguing there. Thanks, Davidlohr
