getconf return values

Hi,

When I issue getconf CPU_VERSION it returns on some machines value 528 and on others 532. I suspect it has something to do with CPU-architecture (RISC 1.1 -> 528, RISC 2.0 -> 532). Can someone confirm this? And, what is the meaning of the returned valus? I couldn?t find an explanation in man pages.

Re: getconf return values



To determine the architecture version of the system,
execute the following command:
extract from Patch Name: PHSS_18609.text :
confirmed ? :)
"getconf CPU_VERSION"

This will return an integer which can be mapped
to the PA-RISC architecture version as follows:

528 PA 1.1
532 PA 2.0

Re: getconf return values

From /usr/include/sys/unistd.h

# define CPU_HP_MC68020 0x20C /* Motorola MC68020 */
# define CPU_HP_MC68030 0x20D /* Motorola MC68030 */
# define CPU_HP_MC68040 0x20E /* Motorola MC68040 */
# define CPU_PA_RISC1_0 0x20B /* HP PA-RISC1.0 */
# define CPU_PA_RISC1_1 0x210 /* HP PA-RISC1.1 */
# define CPU_PA_RISC1_2 0x211 /* HP PA-RISC1.2 */
# define CPU_PA_RISC2_0 0x214 /* HP PA-RISC2.0 */
# define CPU_PA_RISC_MAX 0x2FF /* Maximum value for HP PA-RISC systems */


Therefore PA_RISC1_1 is 528 and CPU_PA_RISC2_0 is 532

Re: getconf return values

with

grep $(getconf _SC_CPU_VERSION |awk '{printf("0x%X\n",$0)}') /usr/include/sys/unistd.h

you can get it more comfortable
