Question about pci programming

[Indranil Bhattacharya]

Hi,

 

In freebsd, how do I set a dma mask for a pci device ?  In linux the
kernel api is pci_set_dma_mask(). In particular, I will like to enable
PCI double address cycle mapping (64 bit addressing) for our device.

 

Thanks in advance,

Indranil
