We have differing implementations for display runtime pm in i915 and xe drivers. Add struct of function pointers into display_parent_interface which will contain used implementation of runtime pm.
v2: - add _interface suffix to rpm function pointer struct - add struct ref_tracker forward declaration - use kernel-doc comments Signed-off-by: Jouni Högander <[email protected]> --- include/drm/intel/display_parent_interface.h | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/include/drm/intel/display_parent_interface.h b/include/drm/intel/display_parent_interface.h index 28c976815327a..26bedc360044d 100644 --- a/include/drm/intel/display_parent_interface.h +++ b/include/drm/intel/display_parent_interface.h @@ -7,6 +7,23 @@ #include <linux/types.h> struct drm_device; +struct ref_tracker; + +struct intel_display_rpm_interface { + struct ref_tracker *(*get)(const struct drm_device *drm); + struct ref_tracker *(*get_raw)(const struct drm_device *drm); + struct ref_tracker *(*get_if_in_use)(const struct drm_device *drm); + struct ref_tracker *(*get_noresume)(const struct drm_device *drm); + + void (*put)(const struct drm_device *drm, struct ref_tracker *wakeref); + void (*put_raw)(const struct drm_device *drm, struct ref_tracker *wakeref); + void (*put_unchecked)(const struct drm_device *drm); + + bool (*suspended)(const struct drm_device *drm); + void (*assert_held)(const struct drm_device *drm); + void (*assert_block)(const struct drm_device *drm); + void (*assert_unblock)(const struct drm_device *drm); +}; /** * struct intel_display_parent_interface - services parent driver provides to display @@ -21,6 +38,8 @@ struct drm_device; * check the optional pointers. */ struct intel_display_parent_interface { + /** @rpm: Runtime PM functions */ + const struct intel_display_rpm_interface *rpm; }; #endif -- 2.43.0
