How to enable DMA transiction in child FDO, which is created by custom bus driver(PDO) RRS feed

  • General discussion

  • Hi All,

    I am using windows sample toaster dynamic bus driver for creating PDO's for my PCI board. After creating PDO, i am installing my custom DMA driver on that. here is the problem. in my custom DMA driver i am not able to use  WDF_DMA_ENABLER_CONFIG_INIT/WdfDmaEnablerCreate functions.

    as somewhere i read that for using DMA capabilities your driver should directly communicate with PCI.sys, is it true??

    is not than any idea how to use DMA properties in child device??
