往中断地址中写msg。msix使用读写方式,msi使用pci操作寄存器方式。 都是获取message addr和message data __pci_write_msi_msg:if(entry->pci.msi_attrib.is_msix){void__iomem*base=pci_msix_desc_addr(entry);//目标msix entrywritel(msg->address_lo,base+PCI_MSIX_ENTRY_LOWER_ADDR);writel(msg->addres...

Instead of going all the way to stack a IP block specific domain on top of the generic MSI domain this ended in a construct which provides a "global" platform MSI domain which allows overriding the irq_write_msi_msg() callback per allocation. In course of the lengthy discussions we ...
