Subject: [PATCH] ras-mce-handler: Add support for Hygon Dhyana family 18h processor
Date: Thu, 23 May 2019 21:00:22 +0800 [thread overview]
Message-ID: <1558616422-22997-1-git-send-email-puwen@hygon.cn> (raw)
The Hygon Dhyana family 18h processor is derived from AMD family 17h.
The Hygon Dhyana support to Linux is already accepted upstream[1].
Add Hygon Dhyana support to mce handler of rasdaemon in order to handle
MCE events on Hygon Dhyana platforms.
