When the number of online CPUs is less than 16, we found that it will fail to allocate 32 MSI interrupts (including 16 affinity interrupts) after the hisi_sas module is unloaded and then reloaded.
After analysis, it is found that a bug exists when the ITS releases interrupt resources, and this patch set contains a bugfix patch and a patch for appending debugging information.
Luo Jiaxing (2): irqchip/gic-v3-its: don't set bitmap for LPI which user didn't allocate genirq/msi: add an error print when __irq_domain_alloc_irqs() failed
