From: Anton Blanchard Date: Tue, 30 Jun 2009 23:00:49 +0000 (+1000) Subject: perf report: Add hypervisor dso X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fb9c818873a788c5c01c9868cc6050df96e2c7df;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git perf report: Add hypervisor dso Add a dso for hypervisor samples. We don't get any symbol information on the ppc64 hypervisor but this at least gives us a high level summary of the time spent in there.
