Subject: top: always validate that p-core/e-core identification
X-Git-Tag: v4.0.1rc3~3
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c7568b28fbca2d808e8773c1db939fddf2d00f8a;p=procps-ng

top: always validate that p-core/e-core identification

Prior to this commit, when the '5' key was struck, top
would check for the presence of e-cores just one time.

That meant if a some cpu was brought online, and it in
turn exposed a new e-core after top has started, users
needed a top restart to activate the  new '5' feature.

So, now we'll check for any e-cores with each '5' key.
