From Pu Wen <> Subject [PATCH 00/11] Add support for Hygon's Dhyana Family 18h processor Date Sat, 9 Jun 2018 21:20:10 +0800 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")/PCIE Device Vendor ID

(0x1D94)/Family series number(Family 18h).



To enable the support of Linux kernel to Hygon's CPU, we added a new

vendor type (X86_VENDOR_HYGON, with value of 9) in arch/x86/include/

asm/processor.h, and shared most of kernel support codes with AMD

family 17h.



These patches have been applied and tested successfully in Hygon's

Dhyana SoC silicon. Also tested on AMD's EPYC (Family 17h) processor

works fine and makes no harm to existing codes.



Thanks.
