"uname -p" on a AMD hardware shows i386 why?
Hi,
We have Solaris 10 installed on an AMD hardware.
Why does the "uname -p" command, which is supposed to display the processor type return i386?
I should have displayed x86_64, isn't it?
# uname -p
i386
# psrinfo -pv
The physical processor has 1 virtual processor (0)
x86 (AuthenticAMD family 15 model 5 step 10 clock 2389 MHz)
AMD Opteron(tm) Processor 850
The physical processor has 1 virtual processor (1)
x86 (AuthenticAMD family 15 model 5 step 10 clock 2389 MHz)
AMD Opteron(tm) Processor 850
The physical processor has 1 virtual processor (2)
x86 (AuthenticAMD family 15 model 5 step 10 clock 2389 MHz)
AMD Opteron(tm) Processor 850
The physical processor has 1 virtual processor (3)
x86 (AuthenticAMD family 15 model 5 step 10 clock 2389 MHz)
AMD Opteron(tm) Processor 850
# isainfo -kv
64-bit amd64 kernel modules
Please suggest,
Thanks & Regards,

Depends on what is intended by 'type', I suppose. Even on SPARC, the individual processor model is not shown, just 'sparc'. Both of them form processor families which have upward binary compatibility for executables.
Use other commands like you've done (such as psrinfo and isainfo) to get more specific processor information.
I guess the question is, why do you care about the specific processor model? What depends on that information? Given that, we might be able to suggest alternatives.

Hi,
I am looking for a way in which end users / developers at my location can determine the hardware architecture by themselves, without needing to be root user.
They determine the hardware architecure of a linux server themselves by using the "uname -m" command as shown below:
[root@bangpcrh214 ~]# uname -m
i686
[root@bangpcia3 ~]# uname -m
ia64
[root@bgpcem15 ~]# uname -m
x86_64
[root@bangpcplin1 ~]# uname -m
ppc64
However on a solaris server irrespective of i686 or x86_64 (EM64T/AMD) the "uname -m" command shows x86pc.
bash-2.05# uname -m
i86pc
below output is from a AMD server:
# uname -m
i86pc
# uname -m
sun4u
Please suggest,
Thanks & Regards

I don't have access to an opteron system at the moment. I assume that 'uname -k' also is identical though.
psrinfo -v (which you showed earlier) does not require root access.
I'm not sure if 'prtdiag' works properly on the original release of Solaris 10, but it should be available on later versions. It will mention the processor type.

I have no idea where that is coming from.
$ id
uid=1004(ddunham) gid=10(staff)
$ /usr/sbin/psrinfo
0on-linesince 09/11/06 16:51:14
1on-linesince 09/11/06 16:51:15
In addition, I don't see that error message within psrinfo...
# strings /usr/sbin/psrinfo | grep root

Sorry. Was thinking 'arch -k'. But I'm afraid that'll give the same information as 'uname -m'.
