Hi Kirill, You'll need to be a little more specific :) Are you writing a custom driver for this card or does a driver exist and you want to enable DMA use? Assuming you are writing a driver, then you'll need to tell us all what the DMA controller chip is. For example, PLX-Technologies makes a wide range of PCI controller chips, eg. the PLX PCI-9054 is a Bus Master/Target device. Only a Bus Master capable device can perform DMA. Give us some more info and we can start a discussion. The output of lspci might be useful. First type lspci (or /sbin/lspci) to see all devices, then use the syntax /sbin/lspci -s 01:04.0 -vv where 01:04.0 would be replaced with the bus/device IDs of your PCI board. The vv option gives verbose info as to the capabilities of the board.
