From 1f828b4dd40264028d9b481c0412e63837d968f6 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Mon, 14 Oct 2024 10:55:25 +0200 Subject: [PATCH 0494/5403] drm/client: Make client support optional MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Only build client code if DRM_CLIENT has been selected. Automatially do so if one of the default clients has been enabled. If client support has been disabled, the helpers for client-related events are empty and the regular client functions are not present. Amdgpu has an internal DRM client, so it has to select DRM_CLIENT by itself unconditionally. v3: - provide empty drm_client_debugfs_init() if DRM_CLIENT=n (kernel test robot) Signed-off-by: Thomas Zimmermann Cc: Alex Deucher Cc: "Christian König" Cc: Xinhui Pan Reviewed-by: Jonathan Cavitt Link: https://patchwork.freedesktop.org/patch/msgid/20241014085740.582287-12-tzimmermann@suse.de --- drivers/gpu/drm/drm_client_event.c | 2 ++ drivers/gpu/drm/drm_debugfs.c | 1 - drivers/gpu/drm/drm_internal.h | 8 ++++++++ include/drm/drm_client.h | 2 -- include/drm/drm_client_event.h | 13 +++++++++++++ 5 files changed, 23 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/drm_client_event.c b/drivers/gpu/drm/drm_client_event.c index c52e93643672..e303de564485 100644 --- a/drivers/gpu/drm/drm_client_event.c +++ b/drivers/gpu/drm/drm_client_event.c @@ -14,6 +14,8 @@ #include #include +#include "drm_internal.h" + /** * drm_client_dev_unregister - Unregister clients * @dev: DRM device diff --git a/drivers/gpu/drm/drm_debugfs.c b/drivers/gpu/drm/drm_debugfs.c index 52783eac078e..536409a35df4 100644 --- a/drivers/gpu/drm/drm_debugfs.c +++ b/drivers/gpu/drm/drm_debugfs.c @@ -32,7 +32,6 @@ #include #include #include -#include #include #include #include diff --git a/drivers/gpu/drm/drm_internal.h b/drivers/gpu/drm/drm_internal.h index 1705bfc90b1e..b2b6a8e49dda 100644 --- a/drivers/gpu/drm/drm_internal.h +++ b/drivers/gpu/drm/drm_internal.h @@ -48,6 +48,14 @@ struct drm_prime_file_private; struct drm_printer; struct drm_vblank_crtc; +/* drm_client_event.c */ +#if defined(CONFIG_DRM_CLIENT) +void drm_client_debugfs_init(struct drm_device *dev); +#else +static inline void drm_client_debugfs_init(struct drm_device *dev) +{ } +#endif + /* drm_file.c */ extern struct mutex drm_global_mutex; bool drm_dev_needs_global_mutex(struct drm_device *dev); diff --git a/include/drm/drm_client.h b/include/drm/drm_client.h index c03c4b0f3e94..3b13cf29ed55 100644 --- a/include/drm/drm_client.h +++ b/include/drm/drm_client.h @@ -236,6 +236,4 @@ int drm_client_modeset_dpms(struct drm_client_dev *client, int mode); drm_for_each_connector_iter(connector, iter) \ if (connector->connector_type != DRM_MODE_CONNECTOR_WRITEBACK) -void drm_client_debugfs_init(struct drm_device *dev); - #endif diff --git a/include/drm/drm_client_event.h b/include/drm/drm_client_event.h index 72c97d111169..99863554b055 100644 --- a/include/drm/drm_client_event.h +++ b/include/drm/drm_client_event.h @@ -5,10 +5,23 @@ struct drm_device; +#if defined(CONFIG_DRM_CLIENT) void drm_client_dev_unregister(struct drm_device *dev); void drm_client_dev_hotplug(struct drm_device *dev); void drm_client_dev_restore(struct drm_device *dev); void drm_client_dev_suspend(struct drm_device *dev, bool holds_console_lock); void drm_client_dev_resume(struct drm_device *dev, bool holds_console_lock); +#else +static inline void drm_client_dev_unregister(struct drm_device *dev) +{ } +static inline void drm_client_dev_hotplug(struct drm_device *dev) +{ } +static inline void drm_client_dev_restore(struct drm_device *dev) +{ } +static inline void drm_client_dev_suspend(struct drm_device *dev, bool holds_console_lock) +{ } +static inline void drm_client_dev_resume(struct drm_device *dev, bool holds_console_lock) +{ } +#endif #endif -- 2.54.0
