在PL1129平台上,如何檢驗新的攝相機或編碼晶片驅動程式(Sensor or decoder chip Driver)傳送影像是否正確?
目前應該先確定grabber是否正確收到sensor傳過來的資料....
After boot, the kernel frees up a special section; functions marked with __init and data structures marked with __initdata are dropped after boot is complete (within modules this directive is currently ignored). __exit is used to declare a function which is only required on exit: the function will be dropped if this file is not compiled as a module. See the header file for use. Note that it makes no sense for a function marked with __init to be exported to modules with EXPORT_SYMBOL() - this will break.
Static data structures marked as __initdata must be initialised (as opposed to ordinary static data which is zeroed BSS) and cannot be const.
