| |
As a new x86 CPU Vendor, Shanghai Zhaoxin Semiconductor Co., Ltd. ("Zhaoxin") provide high performance general-purpose x86 processors.
CPU Vendor ID "Shanghai" belongs to Zhaoxin.
To enable the supports of Linux kernel to Zhaoxin's CPUs, add a new vendor type (X86_VENDOR_ZHAOXIN, with value of 10) in arch/x86/include/asm/processor.h.
To enable the support of Linux kernel's specific configuration to Zhaoxin's CPUs, add a new file arch/x86/kernel/cpu/zhaoxin.c.
This patch series have been applied and tested successfully on Zhaoxin's Soc silicon. Also tested on other processors, it works fine and makes no harm to the existing codes.
v1->v2: - Rebased on 5.2.0-rc2 and tested against it. - remove GPL "boilerplate" text in the patch. - adjust signed-off-by: line match From: line. - run patch series through checkpatch.pl.
v1: - Rebased on 5.2.0-rc1 and tested against it. - Split the patch set to small series of patches. - Rework patch descriptions.
TonyWWang (3): x86/cpu: Create Zhaoxin processors architecture support file ACPI, x86: add Zhaoxin processors support for NONSTOP TSC x86/acpi/cstate: add Zhaoxin processors support for cache flush policy in C3
