DMA/TCE and Interrupt Remapping Linux Kernel equivalent on IBM system

Hi,

Can anyone please explain what do the following Linux kernel options do?

- Enable Intel DMA Remapping Devices by default
- Support for Interrupt Remapping

Now lets say I am not using Intel but instead using IBM POWER, what
would be the similar
options?
Are these enabled by default on IBM POWER?

All kinds of help is truly appreciated.


Thanks!


Marc
