The etnaviv driver causes a link failure if it is built-in but THERMAL is built as a module: drivers/gpu/drm/etnaviv/etnaviv_gpu.o: In function `etnaviv_gpu_bind': etnaviv_gpu.c:(.text+0x4c4): undefined reference to `thermal_of_cooling_device_register' etnaviv_gpu.c:(.text+0x600): undefined reference to `thermal_cooling_device_unregister' drivers/gpu/drm/etnaviv/etnaviv_gpu.o: In function `etnaviv_gpu_unbind': etnaviv_gpu.c:(.text+0x2aac): undefined reference to `thermal_cooling_device_unregister' Adding a Kconfig dependency on THERMAL || !THERMAL to avoid this causes a dependency loop on x86_64: drivers/gpu/drm/tve200/Kconfig:1:error: recursive dependency detected! For a resolution refer to Documentation/kbuild/kconfig-language.txt subsection "Kconfig recursive dependency limitations" drivers/gpu/drm/tve200/Kconfig:1: symbol DRM_TVE200 depends on CMA For a resolution refer to Documentation/kbuild/kconfig-language.txt subsection "Kconfig recursive dependency limitations" mm/Kconfig:489: symbol CMA is selected by DRM_ETNAVIV For a resolution refer to Documentation/kbuild/kconfig-language.txt subsection "Kconfig recursive dependency limitations" drivers/gpu/drm/etnaviv/Kconfig:2: symbol DRM_ETNAVIV depends on THERMAL For a resolution refer to Documentation/kbuild/kconfig-language.txt subsection "Kconfig recursive dependency limitations" drivers/thermal/Kconfig:5: symbol THERMAL is selected by ACPI_VIDEO For a resolution refer to Documentation/kbuild/kconfig-language.txt subsection "Kconfig recursive dependency limitations" drivers/acpi/Kconfig:189: symbol ACPI_VIDEO is selected by BACKLIGHT_CLASS_DEVICE For a resolution refer to Documentation/kbuild/kconfig-language.txt subsection "Kconfig recursive dependency limitations" drivers/video/backlight/Kconfig:158: symbol BACKLIGHT_CLASS_DEVICE is selected by DRM_PARADE_PS8622 For a resolution refer to Documentation/kbuild/kconfig-language.txt subsection "Kconfig recursive dependency limitations" drivers/gpu/drm/bridge/Kconfig:62: symbol DRM_PARADE_PS8622 depends on DRM_BRIDGE For a resolution refer to Documentation/kbuild/kconfig-language.txt subsection "Kconfig recursive dependency limitations" drivers/gpu/drm/bridge/Kconfig:1: symbol DRM_BRIDGE is selected by DRM_TVE200 To work around this, add a new option DRM_ETNAVIV_THERMAL to optionally enable thermal throttling support and make DRM_ETNAVIV select THERMAL at the same time.
