pci spec中,没有明确要求intx 和msi 不能共存。 pci dirver中,一般是在使能msi/msi-x的时候,关闭intx。 如下代码: drivers/pci/msi.c static int msi_capability_init(struct pci_dev *dev, int nvec, struct irq_affinity *affd) { ... /* Set MSI enabled bits */ pci_intx_for_msi(dev, 0)...

#definepci_enable_msi(pdev) pci_enable_msi_block(pdev, 1) 这里看到,实际上它调用了pci_enable_msi_block接口。同样在msi-HOWTO中也提到了这个函数,有如下说明: intpci_enable_msi_block(structpci_dev*dev,intcount) This variation on the above call allows a device driver to request multiple MSIs...
