Some questions about DM8168 Linux pcie driver

Hi all:

I download TI81XX-LINUX-PSP-04.04.00.02.tgz to run the TI81XX PSP PCI Express Endpoint Boot Driver.

followed TI81XX_PSP_PCI_Express_Endpoint_Boot_Driver_User_Guide.pdf,

i boot my ep mode.

But as a newer to pcie, i still have some questions :

1. How to use TI81XX-LINUX-PSP-04.04.00.02.tgz patches, so many pathces,

should i have to patch one by one to the kernel src code ?

2. Followed TI81XX_PSP_PCI_Express_Endpoint_Boot_Driver_User_Guide,

I boot my dm8168 ep from dm8168 rc successfully,

the qustions is how to use the driver at the userspace, there is no ep application interface then ?

3.How to enable  EDMA transfer and MSI in this driver RC?

4.What about the EP side should i have to write a new driver for ep side?

5.when EP is boot from nand there is no pcie init is done in the u-boot, should i have to write this by myself?

Can someone answer me these qustions ?

best regards

xavier
