WarpDrive is a general accelerator framework for the user application to
access the hardware without going through the kernel in data path.
The kernel component to provide kernel facility to driver for expose the
user interface is called uacce. It a short name for

Thank you.

Thanks, Arnd,
You are right. This is the same IP as hip04_mdio.c. We just mis-understand the
hardware design. We will merge them and re-submit the patches.

The patchset is porting from some internal-use drivers, it is tested and
working fine with the hardware. But some detail design is not that good.
But we want to know if the community can accept the structure/arch before
refining it. Thank you.

This is to add basic ethernet support for HNS. It is one of the way to use
the HNS acceleration engine. But most of the decoding/encoding capability
of the AE cannot be used in this way.
This submit contains the basic feature as a ethernet driver. More will be
added later.

There are two bugfixes in this patch:
1. When the execution go to the ib_umem_odp_get() path, pid should be put
back.
2. When the memory allocation fail, the pid also should be put back before
exit.
