pa-risc1.1 pa-risc2.0

[jerry1]

What is the difference between
pa-risc1.1 pa-risc2.0? How can I tell which
one I have? I know my servers are not
Itanium processors.

[Torsten. · Accepted solution]

pa-risc1.1 and pa-risc2.0 are both PA-RISC CPUs.


Go to sam -> performance monitors -> system properties

result can be similar to this:

CPU Version: 1.1e PA7300

this is a PA-7300 CPU pa-risc1.1

CPU(0) PA8700 3.1

PA-RISC = ??

It is a stepwise process to determine the PARISC architecture of the CPU unless you can code it in C. See the example below:

-- Determine the CPU version
# getconf CPU_VERSION
532

-- Convert above decimal value to hexadecimal
# echo 0d532=x | adb
214

-- Match hex value to PARISC version given in the unistd.h file
# grep 0x214 /usr/include/sys/unistd.h
# define CPU_PA_RISC2_0 0x214 /* HP PA-RISC2.0 */

So the above CPU is a PA-RISC 2.0

Yes, definitely. The PA in PA8700 gives it away.

Sandman, thank you very much for excellent tip

Wow Sandman, how did you figure that out?

Does ported versions of software for
PA-RISC 1.0 work with PA-RISC 2.0 ?

Thanks guys

Look at the manpage of sysconf(2). The stepwise procedure was gleaned from that manpage. It has the information needed to classify the PA-RISC version of the processor.

I would say porting from PARISC 1.0 to PARISC 2.0 should not be a problem owing to backward compatibility but then again this is one of those questions that only HP can provide a definitive answer for.
