Subject: [PATCH 67/84] lscpu: Fix model and model name on Power Systems
|
|
|
b394b9 |
|
|
|
b394b9 |
On Power System, lspcu presently displays system model number instead of
|
|
|
b394b9 |
processor model name. 'model' tag in cpuinfo contains system model name,
|
|
|
b394b9 |
not processor model. Instead it uses 'cpu' tag for processor model name.
|
|
|
b394b9 |
Also it uses 'revision' tag for processor model.
|
|
|
b394b9 |
|
|
|
b394b9 |
Fix lspcu so that it displays processor model number. Also display processor
|
|
|
b394b9 |
model name.
