My understanding is: 1. OSXSAVE must be enabled 2. AVX must be enabled 3. XGETBV must have XMM & XMM state enabled Otherwise AVX can not be used. This (for example) causes Xen to fail miserably. -- 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.
