The 1108 * type defines the type of event, the length specifies the total 1109 * length of the event (including the header), and user_data is 1110 * typically a 64 bit value passed with the ioctl that triggered the 1111 * event. A read on the drm fd will always only return complete 1112 * events, that is, if for example the read buffer is 100 bytes, and 1113 * there are two 64 byte events pending, only one will be returned. 1114 * 1115 * Event types 0 - 0x7fffffff are generic drm events, 0x80000000 and 1116 * up are chipset specific. 1117 */ 1118struct drm_event { 1119 __u32 type; 1120 __u32 length; 1121}; 1122 1123#define DRM_EVENT_VBLANK 0x01 1124#define DRM_EVENT_FLIP_COMPLETE 0x02 1125#define DRM_EVENT_CRTC_SEQUENCE 0x03 1126 1127struct drm_event_vblank { 1128 struct drm_event base; 1129 __u64 user_data; 1130 __u32 tv_sec; 1131 __u32 tv_usec; 1132 __u32 sequence; 1133 __u32 crtc_id; /* 0 on older kernels that do not support this */ 1134}; 1135 1136/* Event delivered at sequence.
