Sun4v has 4 interrupt queues: cpu, device, resumable errors, and non-resumable errors. A set of head/tail offset pointers help maintain a work queue in physical memory. The entries are 64-bytes in size. Each queue is allocated then registered with the hypervisor as we bring cpus up. The two error queues each get a kernel side buffer that we use to quickly empty the main interrupt queue before we call up to C code to log the event and possibly take evasive action.
