Hi, all. I have some questions about Multi-touch(MT) Protocal. First, what is the purpose of ABS_MT_TOUCH_MAJOR event? I wonder how it is used at userspace side. Should the ABS_MT_TOUCH_MAJOR be the mininum set of events for multi touch? I'm not sure whether this question is valid because of first question. Finally, what is difference of ABS_MT_TOUCH_MAJOR and ABS_MT_WIDTH_MAJOR? I read the MT Protocol document of kernel, but i cannot understand above things clearly.
