Vendor Unique iSCSI CRC32C

256 T10000: Interface Reference Manual August 2016

Vendor Unique iSCSI CRC32C

Build Instructions

The following instructions must be put into a Makefile. Include all of the “C” code

identified in all sections below into a file called main.c and put the SPARC assembler

in a file called crc32.il. Then run “make”.

MACH:sh = uname -p

# SunOS

i386_CFLAGS =

sparc_CFLAGS = crc32.il

# Linux

x86_64_CFLAGS =

CFLAGS = $($(MACH)_CFLAGS)

main : main.c

cc $(CFLAGS) -o main main.c

Main Function and Defines

#include <unistd.h>

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#if defined(__sparc)

#define CRC32C_SIZE 8 /* 8 data bytes per cpu crc inst */

#else

#if defined(__amd64) || defined(__x86_64)

#define CRC32C_INST "0x48, " /* byte code for 64-bit code */

#define CRC32C_SIZE 8 /* 8 data bytes per cpu crc inst */

#else

#define CRC32C_INST /* no inst byte code for 32-

bit code */

#define CRC32C_SIZE 4 /* 4 data bytes per cpu crc inst */

#endif

#define CRC32C_ALIGN (CRC32C_SIZE - 1)

#define CRC32C_XOR 0xFFFFFFFF /* ending polynomial crc xor

value */

#define CRC32C_INIT 0xFFFFFFFF

#define CRC32C_LEN 4 /* crc length in bytes */

#if defined(__sun__) || defined(__SunOS)
