Description Riccardo 2005-01-31 06:47:32 UTC 
the CPU type of my comptuer is reported wrong. Both uname and /proc/cpuinfo show this.

Reproducible: Always
Steps to Reproduce:
1. cat /proc/cpuinfo
2. uname -a

Actual Results:  
Linux meriadoc 2.4.28-sparc #6 Mon Nov 29 01:26:10 CET 2004 sparc sun4m Texas
Instruments, Inc. - MicroSparc GNU/Linux

cpu             : Texas Instruments, Inc. - MicroSparc
fpu             : SuperSparc on-chip FPU
promlib         : Version 3 Revision 2
prom            : 2.22
type            : sun4m
ncpus probed    : 1
ncpus active    : 1
BogoMips        : 39.83
MMU type        : TI Viking
contexts        : 65536
nocache total   : 2097152
nocache used    : 410624

Expected Results:  
I would have expected "SuperSparc" as a cpu since I have a SM30 SuperSparc module.
The MicroSparc processor is quite rare (used only in the IPC IIRC, the
MicroSparc II being used more widely).
Also note how cpuinfo is inconsistent between CPU and FPU. I don't remember if
the MicroSparc is a v8 cpu as the MicroSparcII, in this case it would be of the
same generation of the SuperSparc and so a misdetection shouldn't cause big
problems. ALso I dont know how extensively this information is used and so if it
can be more than just a cosmetic problem.

Comment 1 Ciaran McCreesh 2005-01-31 09:01:20 UTC 
What kind of box is this?
Comment 2 Riccardo 2005-01-31 10:06:51 UTC 
it is a SS10 with a single SM30 module
Comment 3 Josh Grebe (RETIRED) gentoo-dev 2005-08-16 19:28:51 UTC 
This is a kernel issue, not a Gentoo issue. I'd suggest getting the part number
off the CPU and reporting it to the sparc-linux mailing list.
