From 3f98bc4991df8e7b5972489b4632e1e5c03cd1ee Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 11 Jan 2006 22:42:51 +0100 Subject: [PATCH] i386/x86-64: Update AMD CPUID flags Print bits for RDTSCP, SVM, CR8-LEGACY. Also now print power flags on i386 like x86-64 always did. This will add a new line in the 386 cpuinfo, but that shouldn't be an issue - did that in the past too and I haven't heard of any breakage. I shrunk some of the fields in the i386 cpuinfo_x86 to chars to make up for the new int "x86_power" field. Overall it's smaller than before.
