Subject: [PATCH] drivers/perf: arm_pmu: Show PMU version on boot
Date: Thu, 30 Jul 2020 18:47:21 +0800 [thread overview]
Message-ID: <1596106041-7688-1-git-send-email-zhangshaokun@hisilicon.com> (raw)
The @pmuver field has been initialized and can tell the PMU version.
Let's show it on boot and the user obtains this information directly.
