How to use MSI interupt and DMA on dm8168

Hi all:

Followed TI81XX_PSP_PCI_Express_Endpoint_Boot_Driver_User_Guide,

I boot my dm8168 ep from dm8168 rc successfully,

And now i want to use MSI and DMA to improve the transmission efficiency,

As the epboot driver run at RC part  do not support interupt and DMA transfer,

How should add this module then?

I also see TI81XX_PSP_PCI_Express_Endpoint_Driver_User_Guide,

 ti81xx_pcie_epdrv.ko and ti81xx_edma.ko ,

EDMA transfer enable and MSI interrupt, can i use this two modules when ep is loaded from RC

without ti81xx_pcie_rcdrv.ko,just use ti81xx_pcie_bootdrv.ko instead ?

If not how to change this

best regards
