From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- ANDROID_3.4.5/arch/x86/include/asm/msr.h | 319 ------------------------------- 1 file changed, 319 deletions(-) delete mode 100644 ANDROID_3.4.5/arch/x86/include/asm/msr.h (limited to 'ANDROID_3.4.5/arch/x86/include/asm/msr.h') diff --git a/ANDROID_3.4.5/arch/x86/include/asm/msr.h b/ANDROID_3.4.5/arch/x86/include/asm/msr.h deleted file mode 100644 index 95203d40..00000000 --- a/ANDROID_3.4.5/arch/x86/include/asm/msr.h +++ /dev/null @@ -1,319 +0,0 @@ -#ifndef _ASM_X86_MSR_H -#define _ASM_X86_MSR_H - -#include - -#ifndef __ASSEMBLY__ - -#include -#include - -#define X86_IOC_RDMSR_REGS _IOWR('c', 0xA0, __u32[8]) -#define X86_IOC_WRMSR_REGS _IOWR('c', 0xA1, __u32[8]) - -#ifdef __KERNEL__ - -#include -#include -#include - -struct msr { - union { - struct { - u32 l; - u32 h; - }; - u64 q; - }; -}; - -struct msr_info { - u32 msr_no; - struct msr reg; - struct msr *msrs; - int err; -}; - -struct msr_regs_info { - u32 *regs; - int err; -}; - -static inline unsigned long long native_read_tscp(unsigned int *aux) -{ - unsigned long low, high; - asm volatile(".byte 0x0f,0x01,0xf9" - : "=a" (low), "=d" (high), "=c" (*aux)); - return low | ((u64)high << 32); -} - -/* - * both i386 and x86_64 returns 64-bit value in edx:eax, but gcc's "A" - * constraint has different meanings.
