* DRM_IOCTL_MODE_GETFB2 - Get framebuffer metadata.

*
|

|
* This queries metadata about a framebuffer. User-space fills
|

|
||
|
|
* struct as the output.
|

|
|
*
|
||
|
|
* If the client is DRM master or has &CAP_SYS_ADMIN, &drm_mode_fb_cmd2.handles
|
||
|
|
* will be filled with GEM buffer handles. Planes are valid until one has a
|
||
|
|
* zero handle -- this can be used to compute the number of planes.
|
||
|
|
*
|
||
|
|
* Otherwise, &drm_mode_fb_cmd2.handles will be zeroed and planes are valid
|
||
|
|
* until one has a zero &drm_mode_fb_cmd2.pitches.
|
||
|
|
*
|
||
|
|
* If the framebuffer has a format modifier, &DRM_MODE_FB_MODIFIERS will be set
|
||
|
|
* in &drm_mode_fb_cmd2.flags and &drm_mode_fb_cmd2.modifier will contain the
|
||
|
|
* modifier. Otherwise, user-space must ignore &drm_mode_fb_cmd2.modifier.
