[PATCH 1/2] amdgpu: make pmu support optional

From: Arnd Bergmann
Date: Mon Jul 08 2019 - 10:42:19 EST


When CONFIG_PERF_EVENTS is disabled, we cannot compile the pmu
portion of the amdgpu driver:

drivers/gpu/drm/amd/amdgpu/amdgpu_pmu.c:48:38: error: no member named 'hw' in 'struct perf_event'
struct hw_perf_event *hwc = &event->hw;
~~~~~ ^
drivers/gpu/drm/amd/amdgpu/amdgpu_pmu.c:51:13: error: no member named 'attr' in 'struct perf_event'
if (event->attr.type != event->pmu->type)
~~~~~ ^
...

Use conditional compilation for this file.

Fixes: 9c7c85f7ea1f ("drm/amdgpu: add pmu counters")
