Cover letter [PATCH 00/15] Add support for Hygon Dhyana Family 18h processor
As a new x86 CPU Vendor, Chengdu Haiguang IC Design Co., Ltd (Hygon) is a Joint Venture between AMD and Haiguang Information Technology Co., Ltd., and aims at providing high performance x86 processor for China server market.
The first generation Hygon's processor(Dhyana) originates from AMD technology and shares most of the architecture with AMD's family 17h, but with different CPU vendor ID("HygonGenuine") and family series
number: 18h (Hygon will negotiate with AMD to make sure that only Hygon will use family 18h).
To enable support of Xen to Hygon Dhyana CPU, we add a new vendor type (X86_VENDOR_HYGON, with value of 5), and share most of the codes with AMD family 17h.
This patch series have been applied and tested successfully on Hygon Dhyana processor. Also tested on AMD EPYC (family 17h) processor, it works fine and makes no harm to the existing codes.
