Low-level ioctl-based access to DRM devices.

Structs§

Constants§

DRM_CAP_ADDFB2_MODIFIERS: If set to 1, the driver supports supplying modifiers in [DRM_IOCTL_MODE_ADDFB2].
DRM_CAP_ASYNC_PAGE_FLIP: If set to 1, the driver supports DRM_MODE_PAGE_FLIP_ASYNC for legacy page-flips.
DRM_CAP_ATOMIC_ASYNC_PAGE_FLIP: If set to 1, the driver supports DRM_MODE_PAGE_FLIP_ASYNC for atomic commits.
DRM_CAP_CRTC_IN_VBLANK_EVENT: If set to 1, the kernel supports reporting the CRTC ID in crate::event::raw::DrmEventVblank::crtc_id for crate::event::raw::DRM_EVENT_VBLANK and crate::event::raw::DRM_EVENT_FLIP_COMPLETE events.
DRM_CAP_CURSOR_HEIGHT: A plane height that is valid to use for a cursor plane.
DRM_CAP_CURSOR_WIDTH: A plane width that is valid to use for a cursor plane.
DRM_CAP_DUMB_BUFFER: If set to 1, the driver supports creating “dumb buffers” via DRM_IOCTL_MODE_CREATE_DUMB.
DRM_CAP_DUMB_PREFERRED_DEPTH: The preferred bit depth for “dumb buffers”.
DRM_CAP_DUMB_PREFER_SHADOW: If set to 1, the driver prefers userspace to render to a shadow buffer instead of directly rendering to a dumb buffer. For best speed, userspace should do streaming ordered memory copies into the dumb buffer and never read from it.
DRM_CAP_PAGE_FLIP_TARGET
DRM_CAP_PRIME: Bitfield of supported PRIME sharing capabilities. See DRM_PRIME_CAP_IMPORT and DRM_PRIME_CAP_EXPORT.
DRM_CAP_SYNCOBJ: If set to 1, the driver supports sync objects.
DRM_CAP_SYNCOBJ_TIMELINE: If set to 1, the driver supports timeline operations on sync objects.
DRM_CAP_TIMESTAMP_MONOTONIC: If set to 0, the kernel will report timestamps with CLOCK_REALTIME in crate::event::raw::DrmEventVblank. If set to 1, the kernel will report timestamps with CLOCK_MONOTONIC.
DRM_CAP_VBLANK_HIGH_CRTC: If set to 1, the kernel supports specifying a CRTC index in the high bits of [DrmWaitVblankRequest::type].
DRM_CLIENT_CAP_ASPECT_RATIO: If set to 1, the DRM core will provide aspect ratio information in modes.
DRM_CLIENT_CAP_ATOMIC: If set to 1, the DRM core will expose atomic properties to userspace.
DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOT: Drivers for para-virtualized hardware (e.g. vmwgfx, qxl, virtio and virtualbox) have additional restrictions for cursor planes (thus making cursor planes on those drivers not truly universal,) e.g. they need cursor planes to act like one would expect from a mouse cursor and have correctly set hotspot properties. If this client cap is not set the DRM core will hide cursor plane on those virtualized drivers because not setting it implies that the client is not capable of dealing with those extra restictions. Clients which do set cursor hotspot and treat the cursor plane like a mouse cursor should set this property. The client must enable DRM_CLIENT_CAP_ATOMIC first.
DRM_CLIENT_CAP_STEREO_3D: If set to 1, the DRM core will expose the stereo 3D capabilities of the monitor by advertising the supported 3D layouts in the flags of struct drm_mode_modeinfo.
DRM_CLIENT_CAP_UNIVERSAL_PLANES: If set to 1, the DRM core will expose all planes (overlay, primary, and cursor) to userspace.
DRM_CLIENT_CAP_WRITEBACK_CONNECTORS: If set to 1, the DRM core will expose special connectors to be used for writing back to memory the scene setup in the commit. Depends on client also supporting DRM_CLIENT_CAP_ATOMIC
DRM_IOCTL_DROP_MASTER

DRM_IOCTL_MODE_CREATEPROPBLOB
DRM_IOCTL_MODE_CREATE_DUMB
DRM_IOCTL_MODE_DESTROYPROPBLOB
DRM_IOCTL_MODE_DESTROY_DUMB
DRM_IOCTL_MODE_DIRTYFB: Mark a region of a framebuffer as dirty.

DRM_IOCTL_MODE_GETENCODER
DRM_IOCTL_MODE_GETFB
DRM_IOCTL_MODE_GETPLANE
DRM_IOCTL_MODE_GETPLANERESOURCES
DRM_IOCTL_MODE_GETPROPERTY: User-space can perform a GETPROPERTY request to retrieve information about a property. The same property may be attached to multiple objects.
DRM_IOCTL_MODE_GETRESOURCES
DRM_IOCTL_MODE_MAP_DUMB
DRM_IOCTL_MODE_OBJ_GETPROPERTIES
DRM_IOCTL_MODE_OBJ_SETPROPERTY
DRM_IOCTL_MODE_PAGE_FLIP: Request a page flip on the specified crtc.
DRM_IOCTL_MODE_RMFB
DRM_IOCTL_MODE_SETCRTC
DRM_IOCTL_MODE_SETPLANE
DRM_IOCTL_SET_CLIENT_CAP
DRM_IOCTL_SET_MASTER
DRM_IOCTL_SET_VERSION
DRM_IOCTL_VERSION
DRM_MODE_ATOMIC_ALLOW_MODESET: Allow the update to result in temporary or transient visible artifacts while the update is being applied. Applying the update may also take significantly more time than a page flip. All visual artifacts will disappear by the time the update is completed, as signalled through the vblank event’s timestamp.
DRM_MODE_ATOMIC_FLAGS: Bitfield of flags accepted by DRM_IOCTL_MODE_ATOMIC in DrmModeAtomic::flags.
DRM_MODE_ATOMIC_NONBLOCK: Do not block while applying the atomic commit. The DRM_IOCTL_MODE_ATOMIC request returns immediately instead of waiting for the changes to be applied in hardware. Note, the driver will still check whether the update can be applied before retuning.
DRM_MODE_ATOMIC_TEST_ONLY: Do not apply the atomic commit, and instead check whether the hardware supports this configuration.

DRM_MODE_PAGE_FLIP_ASYNC: Request that the page-flip is performed as soon as possible, ie. with no delay due to waiting for vblank. This may cause tearing to be visible on the screen.
DRM_MODE_PAGE_FLIP_EVENT: Request that the kernel sends back a vblank event (see struct drm_event_vblank) with the crate::event::raw::DRM_EVENT_FLIP_COMPLETE type when the page-flip is done.
DRM_MODE_PAGE_FLIP_FLAGS: Bitmask of flags suitable for DrmModeCrtcPageFlip::flags.

DRM_PRIME_CAP_EXPORT: If this bit is set in DRM_CAP_PRIME, the driver supports exporting PRIME buffers via [DRM_IOCTL_PRIME_HANDLE_TO_FD].
DRM_PRIME_CAP_IMPORT: If this bit is set in DRM_CAP_PRIME, the driver supports importing PRIME buffers via [DRM_IOCTL_PRIME_FD_TO_HANDLE].
