Lines Matching full:planes

28 reports back the number of planes, CRTCs, and connectors. There are three types
29 of DRM planes that the driver can register and work with:
31 * ``DRM_PLANE_TYPE_PRIMARY``: Primary planes represent a "main" plane for a
32   CRTC, primary planes are the planes operated upon by CRTC modesetting and
34 * ``DRM_PLANE_TYPE_CURSOR``: Cursor planes represent a "cursor" plane for a
35   CRTC. Cursor planes are the planes operated upon by the cursor IOCTLs
36 * ``DRM_PLANE_TYPE_OVERLAY``: Overlay planes represent all non-primary,
37   non-cursor planes. Some drivers refer to these types of planes as "sprites"
41 following planes to userspace:
43 * 4 Primary planes (1 per CRTC).
44 * 4 Cursor planes (1 per CRTC).
48    planes.
60 limit of 4 planes across all CRTCs. Atomic commits will be rejected for display
61 configurations using more than 4 planes. Again, it is important to stress that
68 AMDGPU imposes restrictions on the use of DRM planes in the driver.
73 * Overlay planes must be in ARGB8888 or XRGB8888 format
74 * Planes cannot be placed outside of the CRTC destination rectangle
75 * Planes cannot be downscaled more than 1/4x of their original size
76 * Planes cannot be upscaled more than 16x of their original size
80 * Only primary planes have color-space and non-RGB format support
81 * Only overlay planes have alpha blending support
