From 9a4b9efa1d39d7d31bed08fbe5a9b2a03b2759d4 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Wed, 27 Sep 2006 01:50:53 -0700 Subject: [PATCH] x86 microcode: add sysfs and hotplug support Add sysfs support. Currently each CPU has three microcode related attributes. One is 'version' which shows current ucode version of CPU. Tools can use the attribute do validation or show CPU ucode status. one is 'reload' which allows manually reloading ucode. Another is 'processor_flags', which exports processor flags, so we can write tools to check if CPU has latest ucode. Also add suspend/resume and CPU hotplug support.
