Date: Sat, 02 Apr 2011 00:14:00 -0000 [thread overview] Message-ID: <bug-12587-131-CmT5xONrfH@http.sourceware.org/bugzilla/> (raw) In-Reply-To: <bug-12587-131@http.sourceware.org/bugzilla/> http://sourceware.org/bugzilla/show_bug.cgi?id=12587 Ulrich Drepper <drepper.fsp at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|REOPENED |RESOLVED Resolution| |FIXED --- Comment #12 from Ulrich Drepper <drepper.fsp at gmail dot com> 2011-04-02 00:13:38 UTC --- Intel's documentation doesn't say that leaf 4 is guaranteed to contain the cache information if the largest standard function number is >= 4. It only says the data is available that leaf can be queried and that if leaf 2 indicates that leaf 4 contains the data that it can be found there. If you want the patch to be added you have to get Intel to clarify their documentation. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
