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. This patch series 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. 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.
