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. As Hygon will negotiate with AMD to make sure that only Hygon will use family 18h, so try to minimize code modification and share most codes with AMD under this consideration. This patch series have been applied and tested successfully on Hygon Dhyana SoC silicon. Also tested on AMD EPYC (Family 17h) processor, it works fine and makes no harm to the existing codes. v5->v6: - Rebased on 4.19-rc3 and tested against it. - Add Reviewed-by from Borislav Petkov for cacheinfo, smpboot, alternative and kvm. - Rework the patch subjects and patch descriptions. - Rework vendor checking for some patches to minimize the code modification. v4->v5: - Rebased on 4.19-rc1 and tested against it. - Add Reviewed-by from Boris Ostrovsky for Xen. - Rework EDAC patch without vendor checking for minimal modification. v3->v4: - Rebased on 4.18.3 and tested against it. - Merge patchs 05/17 perfctr and 10/17 events in v3 to patch 05/16 PMU for better patch function group. - Add hygon_get_topology_early() in patch 01/16. - Rework vendor checking and refine coding style. - Add Acked-by from Bjorn Helgaas for pci. - Add Acked-by from Rafael J. Wysocki for cpufreq and acpi. v2->v3: - Rebased on 4.18-rc8 and tested against it. - Rework vendor checking codes to improve consistency. v1->v2: - Rebased on 4.18-rc6 and tested against it. - Split the patchset to small series of patches. - Rework patch descriptions. - Create a separated arch/x86/kernel/cpu/hygon.c for Dhyana CPU initialization to reduce long-term maintenance effort.
