RH-Commit: [3/4] 5a049fbd48fda9c1b2d74dc8b389c43547029df2 (anisinha/centos-qemu-kvm)
|
||
|
|
||
|
It is better to check if some older cpu models like 486, athlon, pentium,
|
||
|
penryn, phenom, core2duo etc are available before running their corresponding
|
||
|
tests. Some downstream distributions may no longer support these older cpu
|
||
|
models.
|
||
|
|
||
|
Signature of add_feature_test() has been modified to return void as
|
||
|
FeatureTestArgs* was not used by the caller.
|
||
|
|
||
|
One minor correction. Replaced 'phenom' with '486' in the test
|
||
|
'x86/cpuid/auto-level/phenom/arat' matching the cpu used.
