4 Marvell CN10K DMA packet interface (DPI) driver
10 DPI is a DMA packet interface hardware block in Marvell's CN10K silicon.
11 DPI hardware comprises a physical function (PF), its virtual functions,
14 DPI PF function is an administrative function which services the mailbox
18 mrvl_cn10k_dpi.ko misc driver loads on DPI PF device and services the
21 /dev/mrvl-cn10k-dpi node to set DMA engine and PEM (PCIe interface) port
24 DPI PF driver is just an administrative driver to setup its VF device's
48 DPI VF devices are probed and accessed from user space applications using
49 vfio-pci driver. Below is a sample dpi dma application to demonstrate on
50 how applications use mailbox and ioctl services from DPI PF kernel driver.
