Understanding the Diagnostic Subsystem for AIX

get_cpu_model

Purpose

Returns the CPU model number.

Syntax

#include     <diag/modid.h>
 
unsigned int  get_cpu_model ( model_code )
int model_code;

Description

The get_cpu_model subroutine gets the CPU model number.

init_dgodm must be called before starting this subroutine.

Implementation Specifics

POWER-based

Parameters

Parameter	Description
model_code	Attribute stored in the CuAt database for the sys0 model code. The unsigned integer returned by the function is the raw model code obtained from the IPL control block. Macros are defined in modid.h. These macros can be used to determine the following information: Package Type Tower, Rack, or Desktop. Speed Low, Medium, High, or Turbo Charged. Machine Type Release 1, RSC, Release 2, or PowerPC.

Parameter

Description

model_code

Attribute stored in the CuAt database for the sys0 model code. The unsigned integer returned by the function is the raw model code obtained from the IPL control block. Macros are defined in modid.h. These macros can be used to determine the following information:

Package Type: Tower, Rack, or Desktop.
Speed: Low, Medium, High, or Turbo Charged.
Machine Type: Release 1, RSC, Release 2, or PowerPC.

Return Value

Upon successful completion, the model code as stored in the iplcb structure is returned. Otherwise, a value of -1 is returned.
