[PATCH 0/5] crypto/uadk: introduce uadk crypto driver

[Zhangfei Gao]

Introduce a new crypto PMD for UADK, which relies on UADK library [1].

UADK is a framework for user applications to access hardware accelerators.
UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share
the same page table between IOMMU and MMU.
Thereby user application can directly use virtual address for device dma,
which enhances the performance as well as easy usability.

Currently supported platforms:
HiSilicon kunpeng920 & kunpeng930.

This patch adds a basic framework.

Test:
sudo dpdk-test --vdev=crypto_uadk (--log-level=6)

[PATCH 5/5] doc: Update doc for UADK crypto PMD

[Zhangfei Gao]

Update doc for the new UADK crypto PMD, which relies on UADK library [1].

UADK is a framework for user applications to access hardware accelerators.
UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share
the same page table between IOMMU and MMU.

Sorry for the misunderstanding.
Will change to this

Introduce a new crypto PMD for hardware accelerators based on UADK [1].

UADK is a framework for user applications to access hardware accelerators.
UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share
the same page table between IOMMU and MMU.
Thereby user application can directly use virtual address for device dma,
which enhances the performance as well as easy usability.
