From f50079985c97404d62a208f2937ad6afd3f07f0f Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 22 May 2017 16:50:47 -0700 Subject: [PATCH] perf: Depend on KERNEL_PERF_EVENTS The kernel needs to have PERF_EVENTS built otherwise we will run into the following: root@(none):/# perf top perf_event_open(..., PERF_FLAG_FD_CLOEXEC) failed with unexpected error 89 (Function not implemented) perf_event_open(..., 0) failed unexpectedly with error 89 (Function not implemented) Error: The sys_perf_event_open() syscall returned with 89 (Function not implemented) for event (cycles). /bin/dmesg may provide additional information. No CONFIG_PERF_EVENTS=y kernel support configured? Make sure this functional dependency is captured.
