The first generation Hygon 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 negotiated with AMD to make sure that only Hygon will use family 18h). To enable support of Xen to Hygon Dhyana CPU, add a new vendor type (X86_VENDOR_HYGON, with value of 5), and share most of the code with AMD family 17h. The MSRs and CPUIDs which are used by this patch series are all defined in this PPR[1]. This patch series have been applied and tested successfully on Hygon Dhyana processor, also been tested on AMD EPYC (family 17h) processor. It works fine and makes no harm to the existing code. Reference: [1] https://www.amd.com/system/files/TechDocs/54945_PPR_Family_17h_Models_00h-0Fh.pdf v4->v5: - Rebased over https://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=0763cd26 to fit the new x86 vendor lookup mechanism. - Rework patch 15/15 to fit the new x86 vendor lookup mechanism. - Add Acked-by from Jan Beulich for patch 02/15 and 04/15. - Retain more conditionals from amd.c. - Refine coding style. v3->v4: - Revert opt_cpuid_mask_l7s0_(eax/ebx) to amd.c. - Create a separate patch to fix common cpuid faulting probing issue for AMD and Hygon. - Rename _vpmu_init() to common_init() and move the default case into it. - Coding style refine. v2->v3: - Rebased on 4.13-unstable and tested against it. - Simplify code of hygon.c by re-using early_init_amd(). - Return false in the function probe_cpuid_faulting(). - Adjust code for calculating phys_proc_id for Hygon. - Abstract common function _vpmu_init() and add hygon_vpmu_init(). - Refine some comments and descriptions. - Add Acked-by from Jan Beulich for x86/cpu/mtrr, x86/cpu/mce, x86/spec_ctrl, x86/apic, x86/acpi, x86/iommu, x86/pv, x86/domain, x86/domctl and x86/cpuid. v1->v2: - Rebased on 4.12.0-rc3 and tested against it. - Move opt_cpuid_mask_l7s0_(eax/ebx) to common.c. - Insert Hygon cases after AMD ones instead of above. - Remove (rd/wr)msr_hygon_safe and use (rd/wr)msr_safe instead. - Remove wrmsr_hygon and use wrmsrl instead. - Remove the unnecessary change to xstate. - Refine some codes and comments. - Add Acked-by from Jan Beulich for x86/traps. - Add Acked-by from Wei Liu for tools/libxc.
