Uacce (Unified/User-space-access-intended Accelerator Framework) targets to
provide Shared Virtual Addressing (SVA) between accelerators and processes.
So accelerator can access any data structure of the main cpu.
This differs from the data sharing between cpu and io device, which share
data content rather than address.
Because of unified address, hardware and user space of process can share
the same virtual address in the communication.

Uacce is intended to be used with Jean Philippe Brucker's SVA
patchset[1], which enables IO side page fault and PASID support.
We have keep verifying with Jean's sva patchset [2]
We also keep verifying with Eric's SMMUv3 Nested Stage patches [3]

This series and related zip & qm driver

The library and user application:


Change History:

   uacce: Add documents for uacce
   uacce: add uacce driver

Zhangfei Gao (2):
   crypto: hisilicon - Remove module_param uacce_mode
   crypto: hisilicon - register zip engine to uacce

Would you mind take a look at the patch set?

The patches are also used for verifying the sva feature.
