[dpdk-dev] PA to VA address conversion API in DPDK

[dpdk-dev] PA to VA address conversion API in DPDK

[Devendra Rawat]

Hi,

I am implementing a PMD driver for my ethernet device in DPDK.

I have allocated HW desc. queue for receiving packets. For each desc.
there's a corresponding rte_mbuf allocated and the PA of that mbuf is put
in the desc.

In the RX callback function,
On packet reception I will get the PA from a RX desc. I need to convert
this PA to VA so that I can find the corresponding mbuf address .

Is there any API available or some other way to do PA to VA conversion ?
I need an efficient way of doing PA to VA conversion, as this will be done
for every RX packet.

Thanks,
Deven
