Subject: [RFC PATCH RESEND] tools/perf: Add Hygon Dhyana support
Date: Mon, 12 Nov 2018 15:40:51 +0800
Message-ID: <1542008451-31735-1-git-send-email-puwen@hygon.cn> (raw)

The tool perf is useful for the performance analysis on the Hygon Dhyana
platform. But right now there is no Hygon support for it to analyze the
KVM guest os data. So add Hygon Dhyana support to it by checking vendor
string to share the code path of AMD.
