From 9b779edf4b97798d037bb44fca2719ac184d0f14 Mon Sep 17 00:00:00 2001 From: Jaswinder Singh Rajput Date: Tue, 10 Mar 2009 15:37:51 +0530 Subject: x86: cpu architecture debug code Introduce: cat /sys/kernel/debug/x86/cpu/* for Intel and AMD processors to view / debug the state of each CPU. By using this we can debug whole range of registers and other cpu information for debugging purpose and monitor how things are changing. This can be useful for developers as well as for users.
