From 70097ecfe54a9630e1e77fdc30204a5460228193 Mon Sep 17 00:00:00 2001 From: Mounir IDRASSI Date: Tue, 20 Jun 2017 17:43:35 +0200 Subject: Crypto: Add optimized Camellia assembly implementation for x86_64 based on work by Jussi Kivilinna (https://github.com/jkivilin/supercop-blockciphers). This improve speed by a factor of 2.5 when AES-NI supported by CPU and by 30% if AES-NI not supported. --- src/Crypto/cpu.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/Crypto/cpu.h') diff --git a/src/Crypto/cpu.h b/src/Crypto/cpu.h index 05ce9d8f..68041190 100644 --- a/src/Crypto/cpu.h +++ b/src/Crypto/cpu.h @@ -196,6 +196,8 @@ extern int g_hasSSSE3; extern int g_hasAESNI; extern int g_hasCLMUL; extern int g_isP4; +extern int g_isIntel; +extern int g_isAMD; extern uint32 g_cacheLineSize; void DetectX86Features(); // must be called at the start of the program/driver int CpuId(uint32 input, uint32 *output); @@ -225,6 +227,8 @@ extern int g_hasMMX; #define HasAESNI() g_hasAESNI #define HasCLMUL() g_hasCLMUL #define IsP4() g_isP4 +#define IsCpuIntel() g_isIntel +#define IsCpuAMD() g_isAMD #define GetCacheLineSize() g_cacheLineSize #if defined(__cplusplus) -- cgit v1.2.3
