Step S102 matches abnormal identify with the daily record mark to prestore.
Step S103 if abnormal mark identifies successful match with daily record, is closed according to daily record identifier lookup and daily record mark The log information of connection, and obtain the progress information of process corresponding with direct Memory Allocation.
After direct Memory Allocation corresponding abnormal mark is got, mobile terminal is by acquired abnormal mark and storage The daily record mark stored in reboot operation reason data storehouse is matched.If abnormal mark identifies successful match with daily record, mobile Terminal then identifies to search in the database of storage reboot operation reason according to daily record identifies associated log information with daily record, and Obtain the progress information that process corresponding with direct Memory Allocation carries out.It should be noted that the daily record, which is identified as, causes movement eventually Hold the corresponding mark of log information of reboot operation.Wherein, log information includes but not limited to WiFi power allocation management modules It is middle to occur occurring direct Memory Allocation exception in the nodename of direct Memory Allocation exception and WiFi power allocation management modules Position.Progress information includes but not limited to when direct Memory Allocation occurs abnormal, the title of corresponding process relates to thing process Title, associate thread title, with relate to thing process interaction or the ID (identification, identity) of association process The functional node of WiFi power allocation managements module corresponding with Thread Id and key message point.
In the present embodiment, when mark is consistent with the daily record mark to prestore extremely, then confirm what exception identified and prestored Daily record identifies successful match；If abnormal mark and the daily record mark to prestore are inconsistent, the abnormal daily record identified with prestoring is confirmed It fails to match for mark.Such as when being identified as a extremely, find to identify the daily record mark of a in the database, then confirm abnormal mark Successful match is identified with the daily record to prestore, otherwise, then confirms that it fails to match for the abnormal daily record mark for identifying and prestoring.In other realities It applies in example, may be configured as when mark is associated with the daily record mark to prestore extremely, then confirming the abnormal daily record identified with prestoring Successful match is identified, otherwise, confirms that it fails to match for the abnormal daily record mark for identifying and prestoring.It is arranged to and abnormal mark a1 as worked as When associated daily record is identified as a2, if when the exception that some key message point corresponds to direct Memory Allocation is identified as a1, and in number According to the daily record for being identified as a2 mark is found in storehouse, then the abnormal daily record mark successful match identified with prestoring is confirmed, otherwise, really Recognizing the abnormal daily record mark for identifying and prestoring, it fails to match.
Step S104 restarts daily record according to progress information and log information generation, with mobile eventually according to daily record positioning is restarted Restart reason in end.
After progress information and log information is got, mobile terminal restarts day according to progress information and log information generation Will, and daily record will be restarted and exported to designated position, in order to which mobile terminal is after occurring reboot operation, corresponding staff can With quick obtaining, this restarts daily record, restarts reason according to restart that daily record quickly determines to cause mobile terminal reboot operation.
Further, in logging process is restarted according to progress information and log information generation, mobile terminal is according to specific Form generation restart daily record, in order to which corresponding staff can quickly analyze mobile terminal according to daily record is restarted The reason for reboot operation.
Further, the localization method of restarting based on direct Memory Allocation is somebody's turn to do to further include：
Step a, determines whether the monitoring direct Memory Allocation of key message point correspondence position abnormal Monitoring instruction pair occurs The thread answered, and thread is deployed in Kernel layers of kthreadd processes and kernel processes.
Further, mobile terminal determines its Kernel layers of WiFi power point of monitoring when disposing Kernel layers of process Whether the direct Memory Allocation for presetting key point correspondence position with management module there is abnormal Monitoring instruction and corresponds to thread, and will The corresponding thread of Monitoring instruction is deployed in Kernel layers of kthreadd processes and kernel processes, in order to whole supervise Survey whether Kernel layers of WiFi power allocation management moulds direct Memory Allocation in the block exception occur.It should be noted that prison It is independent operating in the terminal to survey and instruct corresponding thread.
The present embodiment monitors Kernel layers of WiFi power allocation management moulds default key in the block of mobile terminal by working as After exception occurs in the direct Memory Allocation of information point correspondence position, the corresponding abnormal mark of direct Memory Allocation is read；It will be abnormal It identifies and is matched with the daily record mark to prestore；If abnormal mark identifies successful match with daily record, according to daily record identifier lookup Associated log information is identified with daily record, and obtains the progress information of process corresponding with direct Memory Allocation；According to progress information Restart daily record with log information generation, restarting daily record positioning mobile terminal with basis restarts reason.It realizes in mobile terminal not Before generation reboot operation, obtaining mobile terminal in advance can occur that reboot operation is corresponding to restart daily record, in order to it is mobile eventually After reboot operation occurs for end, corresponding staff can quickly determine the original that mobile terminal is caused to be restarted according to daily record is restarted Cause improves the efficiency for the reason for positioning mobile terminal restarts failure and reduces human cost.
Further, propose that the present invention is based on restart localization method the second of direct Memory Allocation based on first embodiment Embodiment.The second embodiment for restarting localization method based on direct Memory Allocation based on direct Memory Allocation with restarting positioning Difference lies in include the first embodiment of method according to the step of state value of Monitoring instruction reading key message point：
Step b presets the first state value of quantity according to Monitoring instruction according to the first reading frequency reading key message point.
Step c, if all determining that direct Memory Allocation does not occur exception according to the first state value of default quantity, according to Two reading frequencies read the second state value that key message point presets quantity.
Step d, if all determining that direct Memory Allocation does not occur exception according to the second state value of default quantity, according to Three reading frequencies read the third state value of key message point, wherein, the second reading frequency is more than the first reading frequency, less than the Three reading frequencies.
Mobile terminal is in the process of state value for reading key message point according to Monitoring instruction：Mobile terminal is according to monitoring Instruction reads key message point according to the first reading frequency and presets the first state value of quantity, and judges read default quantity First state value whether can determine that direct Memory Allocation does not occur exception.If the first state value of read default quantity It can determine that direct Memory Allocation does not occur exception, then read key message point according to the second reading frequency and preset the second of quantity State value, and judge whether the second state value of read default quantity can determine that direct Memory Allocation does not occur exception. If the second state value of read default quantity can determine that direct Memory Allocation does not occur exception, frequency is read according to the 3rd Rate reads the third state value that key message point presets quantity, to determine key message point correspondence position according to third state value Whether direct Memory Allocation there is exception.
Wherein, the second reading frequency is more than the first reading frequency, and less than the 3rd reading frequency.First reading frequency, Two reading frequencies, the 3rd reading frequency and default quantity can be set according to specific needs, can such as be set the first reading frequency To be read once at interval of 1 second, the second reading frequency is arranged to read once at interval of 3 seconds, set of frequency is read by the 3rd To be read once at interval of 5 seconds, default quantity is arranged to 5.I.e. when mobile terminal according to Monitoring instruction continuous 5 times with 1 second between After the state value of reading all shows that direct Memory Allocation exception does not occur, 5 key message points pair were continuously read at interval of 3 seconds The state value answered, if 5 state values read at interval of 3 seconds all showed that direct Memory Allocation does not occur exception, at interval of 5 seconds The corresponding state value of 5 key message points is continuously read, key is determined according to 5 state values continuously read at interval of 5 seconds Whether the direct Memory Allocation of information point correspondence position there is exception.
It should be noted that it in other embodiments, can be further added by setting the reading for reading the dotted state value of key message Frequency, if all show that direct Memory Allocation does not occur abnormal at interval of 5 state values that 5 seconds continuously read, at interval of 8 Second continuously reads the corresponding state value of 5 key message points.This is not particularly limited in the present embodiment.
Further, the localization method of restarting based on direct Memory Allocation is somebody's turn to do to further include：
Whether step e if it is abnormal to determine that direct Memory Allocation occurs according to a first state value, detects mobile terminal Generation reboot operation.
If reboot operation does not occur for mobile terminal, the state of key message point is read according to the 4th reading frequency by step f Value.
Further, if presetting the first shape of quantity according to the first reading frequency reading key message point according to Monitoring instruction During state value, it is abnormal to determine that direct Memory Allocation occurs according to a first state value, mobile terminal then detects whether it sends out Raw reboot operation.If reboot operation does not occur for mobile terminal, mobile terminal reads key message point according to the 4th reading frequency State value.Further, if reboot operation occurs for mobile terminal, show that mobile terminal has been initialized, mobile terminal is then It detects whether to detect the prison for monitoring its Kernel layers of WiFi power allocation management mould default dotted state value of key message in the block Survey instruction.Wherein, the 4th reading frequency can be set according to specific needs, and such as the 4th reading frequency may be configured as reading with first Frequency is equal, is both configured to read once at interval of 1 second；Or it is arranged to unequal with the first reading frequency, such as the 4th is read It is to be read once or every reading in 2 seconds once at interval of 0.8 second to take set of frequency.
In order to make it easy to understand, illustrate the process：When mobile terminal according to Monitoring instruction according to continuous at interval of 1 second During reading 5 dotted state value of key message, if the state value of the key message point read according to the 3rd second determines correspondence position House dog occur abnormal, and reboot operation does not occur for mobile terminal, and mobile terminal is then crucial according to being read once at interval of 0.8 The state value (at this point, the 4th reading frequency is arranged to read once for 0.8 second) of information point.
It is understood that if it is different to determine that direct Memory Allocation occurs according to second state value or third state value Often, mobile terminal then detects whether that reboot operation occurs.
The present embodiment reads the reading frequency of key message point by setting, with crucial in WiFi power allocation managements module When the direct Memory Allocation of information point correspondence position does not occur abnormal, the reading frequency of the dotted state value of key message is read in increase, When direct Memory Allocation does not occur abnormal, to reduce the number for reading the dotted state value of key message.
