Sorry, add a title . Hi I have a problems that I want create a watchpoint to monitor a data for Debug in kernel , but I don't know how to do it , I try the kprobes , but seems it only support create .text section probe , Can't monitor data access , then I try perf_event_create to create a hardware Data watchpoint , it can work , but has a problem: When the data access hit , I don't know how to bypass this time's watchpoint , This need simulate the data access or step the break instructions in data abort Exception handler , seems kernel don't provide these for perf_event .. I test this on ARM arch , My question is that how to create data watchpoint in kernel ? It there some modules have implemented this ?
