Design - - The WiMAX stack is designed to provide for common WiMAX control - services to current and future WiMAX devices from any vendor. - - Because currently there is only one and we don't know what would be the - common services, the APIs it currently provides are very minimal. - However, it is done in such a way that it is easily extensible to - accommodate future requirements. - - The stack works by embedding a struct wimax_dev in your device's - control structures. This provides a set of callbacks that the WiMAX - stack will call in order to implement control operations requested by - the user. As well, the stack provides API functions that the driver - calls to notify about changes of state in the device. - - The stack exports the API calls needed to control the device to user - space using generic netlink as a marshalling mechanism. You can access - them using your own code or use the wrappers provided for your - convenience in libwimax (in the wimax-tools package). - - For detailed information on the stack, please see - include/linux/wimax.h. - -2. Usage - - For usage in a driver (registration, API, etc) please refer to the - instructions in the header file include/linux/wimax.h. - - When a device is registered with the WiMAX stack, a set of debugfs - files will appear in /sys/kernel/debug/wimax:wmxX can tweak for - control. - -2.1. Obtaining debug information: debugfs entries - - The WiMAX stack is compiled, by default, with debug messages that can - be used to diagnose issues. By default, said messages are disabled. - - The drivers will register debugfs entries that allow the user to tweak - debug settings. - - Each driver, when registering with the stack, will cause a debugfs - directory named wimax:DEVICENAME to be created; optionally, it might - create more subentries below it. - -2.1.1. Increasing debug output - - The files named *dl_* indicate knobs for controlling the debug output - of different submodules of the WiMAX stack: - * -# find /sys/kernel/debug/wimax\:wmx0 -name \*dl_\* -/sys/kernel/debug/wimax:wmx0/wimax_dl_stack -/sys/kernel/debug/wimax:wmx0/wimax_dl_op_rfkill -/sys/kernel/debug/wimax:wmx0/wimax_dl_op_reset -/sys/kernel/debug/wimax:wmx0/wimax_dl_op_msg -/sys/kernel/debug/wimax:wmx0/wimax_dl_id_table -/sys/kernel/debug/wimax:wmx0/wimax_dl_debugfs -/sys/kernel/debug/wimax:wmx0/.... # other driver specific files - - NOTE: Of course, if debugfs is mounted in a directory other than - /sys/kernel/debug, those paths will change. - - By reading the file you can obtain the current value of said debug - level; by writing to it, you can set it. - - To increase the debug level of, for example, the id-table submodule, - just write: - -$ echo 3 > /sys/kernel/debug/wimax:wmx0/wimax_dl_id_table - - Increasing numbers yield increasing debug information; for details of - what is printed and the available levels, check the source.
