This section here +explains what exactly those requirements are, and why they exist. + +The short summary is that any addition of DRM uAPI requires corresponding +open-sourced userspace patches, and those patches must be reviewed and ready for +merging into a suitable and canonical upstream project. + +GFX devices (both display and render/GPU side) are really complex bits of +hardware, with userspace and kernel by necessity having to work together really +closely. The interfaces, for rendering and modesetting, must be extremely wide +and flexible, and therefore it is almost always impossible to precisely define +them for every possible corner case.

And debugging such regressions without access to source code is pretty +much impossible. As a consequence this means: + +- The Linux kernel's "no regression" policy holds in practice only for + open-source userspace of the DRM subsystem.

Making sure that the interface indeed covers the use-case fully +leads to a few additional requirements: + +- The open-source userspace must not be a toy/test application, but the real + thing. Specifically it needs to handle all the usual error and corner cases. + These are often the places where new uAPI falls apart and hence essential to + assess the fitness of a proposed interface. + +- The userspace side must be fully reviewed and tested to the standards of that + userspace project.

As + * opposed to all other KMS objects representing hardware (like CRTC, encoder or + * plane abstractions) connectors can be hotplugged and unplugged at runtime. + * Hence they are reference-counted using drm_connector_reference() and + * drm_connector_unreference(). + * + * KMS driver must create, initialize, register and attach at a struct + * &drm_connector for each such sink. The instance is created as other KMS + * objects and initialized by setting the following fields. + * + * The connector is then registered with a call to drm_connector_init() with a + * pointer to the connector functions and a connector type, and exposed through + * sysfs with a call to drm_connector_register(). + * + * Connectors must be attached to an encoder to be used. For devices that map + * connectors to encoders 1:1, the connector should be attached at + * initialization time with a call to drm_mode_connector_attach_encoder(). The + * driver must also set the struct &drm_connector encoder field to point to the + * attached encoder. + * + * For connectors which are not fixed (like built-in panels) the driver needs to + * support hotplug notifications. The simplest way to do that is by using the + * probe helpers, see drm_kms_helper_poll_init() for connectors which don't have + * hardware support for hotplug interrupts. Connectors with hardware hotplug + * support can instead use e.g. drm_helper_hpd_irq_event(). + */ + +struct drm_conn_prop_enum_list { + int type; + const char *name; + struct ida ida; +}; + +/* + * Connector and encoder types. + */ +static struct drm_conn_prop_enum_list drm_connector_enum_list[] = { + { DRM_MODE_CONNECTOR_Unknown, "Unknown" }, + { DRM_MODE_CONNECTOR_VGA, "VGA" }, + { DRM_MODE_CONNECTOR_DVII, "DVI-I" }, + { DRM_MODE_CONNECTOR_DVID, "DVI-D" }, + { DRM_MODE_CONNECTOR_DVIA, "DVI-A" }, + { DRM_MODE_CONNECTOR_Composite, "Composite" }, + { DRM_MODE_CONNECTOR_SVIDEO, "SVIDEO" }, + { DRM_MODE_CONNECTOR_LVDS, "LVDS" }, + { DRM_MODE_CONNECTOR_Component, "Component" }, + { DRM_MODE_CONNECTOR_9PinDIN, "DIN" }, + { DRM_MODE_CONNECTOR_DisplayPort, "DP" }, + { DRM_MODE_CONNECTOR_HDMIA, "HDMI-A" }, + { DRM_MODE_CONNECTOR_HDMIB, "HDMI-B" }, + { DRM_MODE_CONNECTOR_TV, "TV" }, + { DRM_MODE_CONNECTOR_eDP, "eDP" }, + { DRM_MODE_CONNECTOR_VIRTUAL, "Virtual" }, + { DRM_MODE_CONNECTOR_DSI, "DSI" }, + { DRM_MODE_CONNECTOR_DPI, "DPI" }, +}; + +void drm_connector_ida_init(void) +{ + int i; + + for (i = 0; i < ARRAY_SIZE(drm_connector_enum_list); i++) + ida_init(&drm_connector_enum_list[i].ida); +} + +void drm_connector_ida_destroy(void) +{ + int i; + + for (i = 0; i < ARRAY_SIZE(drm_connector_enum_list); i++) + ida_destroy(&drm_connector_enum_list[i].ida); +} + +/** + * drm_connector_get_cmdline_mode - reads the user's cmdline mode + * @connector: connector to quwery + * + * The kernel supports per-connector configuration of its consoles through + * use of the video= parameter.

Applications explicitly request the creation of frame + * buffers through the DRM_IOCTL_MODE_ADDFB(2) ioctls and receive an opaque + * handle that can be passed to the KMS CRTC control, plane configuration and + * page flip functions. + * + * Frame buffers rely on the underlying memory manager for allocating backing + * storage. When creating a frame buffer applications pass a memory handle + * (or a list of memory handles for multi-planar formats) through the + * struct &drm_mode_fb_cmd2 argument. For drivers using GEM as their userspace + * buffer management interface this would be a GEM handle. Drivers are however + * free to use their own backing storage object handles, e.g. vmwgfx directly + * exposes special TTM handles to userspace and so expects TTM handles in the + * create ioctl and not GEM handles. + * + * Framebuffers are tracked with struct &drm_framebuffer. They are published + * using drm_framebuffer_init() - after calling that function userspace can use + * and access the framebuffer object. The helper function + * drm_helper_mode_fill_fb_struct() can be used to pre-fill the required + * metadata fields. + * + * The lifetime of a drm framebuffer is controlled with a reference count, + * drivers can grab additional references with drm_framebuffer_reference() and + * drop them again with drm_framebuffer_unreference(). For driver-private + * framebuffers for which the last reference is never dropped (e.g. for the + * fbdev framebuffer when the struct struct &drm_framebuffer is embedded into + * the fbdev helper struct) drivers can manually clean up a framebuffer at + * module unload time with drm_framebuffer_unregister_private(). But doing this + * is not recommended, and it's better to have a normal free-standing struct + * &drm_framebuffer. + */ + +/** + * drm_mode_addfb - add an FB to the graphics configuration + * @dev: drm device for the ioctl + * @data: data pointer for the ioctl + * @file_priv: drm file for the ioctl call + * + * Add a new FB to the specified CRTC, given a user request.
