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

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

[Arnd Bergmann]

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.

[PATCH 2/2] amdgpu: make SOC15/navi support conditional

[Arnd Bergmann]

Enabling amdgpu but not CONFIG_DRM_AMD_DC leads to a warning:

drivers/gpu/drm/amd/amdgpu/nv.c: In function 'nv_set_ip_blocks':
drivers/gpu/drm/amd/amdgpu/nv.c:400:3: error: #warning "Enable CONFIG_DRM_AMD_DC for display support on navi." [-Werror=cpp]
 # warning "Enable CONFIG_DRM_AMD_DC for display support on navi."
   ^~~~~~~
drivers/gpu/drm/amd/amdgpu/soc15.c: In function 'soc15_set_ip_blocks':
drivers/gpu/drm/amd/amdgpu/soc15.c:653:3: error: #warning "Enable CONFIG_DRM_AMD_DC for display support on SOC15." [-Werror=cpp]

However, CONFIG_DRM_AMD_DC can only be enabled on x86, so we
cannot do that when building for other architectures.

Add another Kconfig symbol to handle the SOC15 and navi, making
sure that we implicitly enable DC.

DC is not limited to x86.  I can drop the warning if that is the concern.
