| Subject: perf tools: Add Hygon Dhyana support |
| |
| [ Upstream commit 4787eff3fa88f62fede6ed7afa06477ae6bf984d ] |
| |
| 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. |
