UADK is an open source accelerator framework, the kernel support part is UACCE, which has been merged in Kernel for several years, targeting to provide Shared Virtual Addressing (SVA) between accelerators and processes. UADK provider users with a unified programming interface to efficiently harness the capabilities of hardware accelerators. It furnishes users with fundamental library and driver support. Now UADK can offer the hardware accelerator engine(e.g: Kunpeng KAE), Arm SVE and Crypto Extension CPU. UADK is hosted by Linaro.

UADK now has already supports different communities for compressor and encryption, such as OpenSSL, DPDK and SPDK, so now, we would like to bring it to Ceph for Acceleration of  zlib compressor. As first step, we can see that,

1. save almost 50% cpu usage compared with no-isal compression in RBD 4M workload
2. save almost 40% cpu usage compared with no-isal compression in RGW put op (4M) workload

The PR is under review, welcome any comments or reviews.

Have a nice day~
