From : Erwan Velu <erwan.velu at free.fr> This patch add the ability to read the long-mode flag from the processor. This helps you to know if the processor is x86_64 capable or not. So "dmi->processor.cpu_flags.lm " is a boolean that represent the "Long Mode" cpu flag. It also add two bugfix : - some cpu flags were shifted due to some "null" messages in the structure - the "BB" cpu type from Intel were not supported This new code comes mainly from the Linux kernel. Greetings are for those who wrote it. Testing and feedback are welcome. Signed-off-by:Erwan Velu <erwan.velu at free.fr> -------------- next part -------------- A non-text attachment was scrubbed...

Also, it might we worthwhile to have the CPUID level/model/stepping fields available. -hpa
