Hi:

This is lvan.zhang. Recently we try to improve the performance of DMA memcpy, so we want to use DRU engine to perform it.

We wonder know whether A72 support DRU?

Hi Ivan,

When you mean A72 supporting DRU are you asking for Linux supporting DRU?

Hi Ivan,

I have confirmed with our Linux expert that there is no support for DRU from A72 Linux side.
There are no plans in future to support from A72 side.

Hope you can resolve the issue.

Best Regards,
Keerthy

Hi Keerthy:

So the answer is A72 is support DRU, but there is no software code for DRU from A72 Linux side?

Ivan,

You understanding is correct - it is supported by hardware but not enabled in linux driver.

you may find some baremetal example under PDK:

\pdk_j7_1_0_0\packages\ti\drv\udma\src

but will have to manually program it.
