All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a method and a system for processing PCIE errors in linux, which are used for processing PCIE error events and avoiding the problem that the system cannot provide reliable service due to errors or faults of the PCIE.
Referring to fig. 1, a method for processing a PCIE error based on linux provided in an embodiment of the present invention includes:
s101, counting the occurrence frequency of each event type of each error event in a PCIE event source;
the counting of the occurrence frequency of the event type of each error event in the PCIE event source includes:
and triggering a timer to start timing, sequentially analyzing the event types of the error events in the PCIE event source, and recording the occurrence times of the error events of the same event type to a corresponding counter.
Specifically, in this embodiment, the occurrence number of each event type needs to be counted; the statistics of the occurrence number of each event type are as follows: the number of occurrences of the same type is recorded, for example: if the event types of the error events in the PCIE event source are sequentially analyzed as follows: m, N, N, N, C, C, C, C, K; the number of occurrences of each event type is: the number of M occurrences was 1, the number of N occurrences was 3, the number of C occurrences was 4, and the number of K occurrences was 1.
S102, if the event type with the occurrence frequency larger than N is detected to exist in the first preset time, marking the error event corresponding to the event type with the occurrence frequency larger than N as a PCIE fault format event; wherein N is a positive integer;
if it is detected that an event type with the occurrence frequency greater than N exists within the first preset time, marking an error event corresponding to the event type with the occurrence frequency greater than N as a PCIE failure format event, including:
detecting whether the timing duration of the timer is a first preset duration or not in real time;
if yes, detecting whether an event type with occurrence frequency more than N times exists in the counter;
and if so, marking the error event corresponding to the event type with the occurrence frequency more than N times as a PCIE fault format event.
Specifically, in this embodiment, the diagnosis is performed according to the error event in the PCIE event source, the diagnosis principle is to perform analysis according to a rule, where the rule indicates that a fault occurs if the same event occurs N times within a certain time T, and then the error information event is marked as a PCIE fault format event.
If it is detected that an event type with the occurrence frequency greater than N exists within a first predetermined time, marking an error event corresponding to the event type with the occurrence frequency greater than N as a PCIE failure format event, including:
and marking error events corresponding to the event types with the occurrence frequency more than 3 in 24 hours as PCIE fault format events.
It is understood that the optimal principle is as follows: iodine series, i.p. pie { N ═ 3, T ═ 24 hours }; that is, the number of occurrences of a certain type of event in 24 hours is 3
For example, in the above-described example, M is 1, N is 3, C is 4, and K is 1, i.e., the number of occurrences of different event types within 24 hours; if N is set to be 3, it can be seen that, only if the number of occurrences of the error event with the event type C is greater than 3, the error event with the event type C is marked as a PCIE failure format event.
When the timing duration of the timer is a first preset duration and a second preset duration is set, the counting is triggered again, the counting is cleared and the timing is started, and the counter is triggered again to be cleared and the counting is started.
It can be understood that, in this embodiment, after detecting that the first predetermined time period is T, the detection may be performed after stopping the second predetermined time period, where the second predetermined time period may be set by itself; for example: if the time interval is desired to be small, the second predetermined period of time is set to 15s, and if the time interval is desired to be long, the predetermined period of time may be set to 1 hour.
S103, if the event type of the PCIE fault format event is judged to be an uncorrectable error, resetting the PCIE link corresponding to the PCIE fault format event.
Specifically, if the PCIE failure format event is an uncorrectable error, the processing method further includes:
judging whether the target equipment corresponding to the PCIE fault format event is the lowest-level equipment or not;
if yes, determining superior equipment connected with the target equipment, and resetting a link between the target equipment and the superior equipment.
Specifically, in the present embodiment, it is determined whether the error is a fatal error according to the event type, and the fatal error is understood as not correcting the error; if so, the PCIE link is reset. And according to the position of the bit, if the device at the bottom level has errors, the upper level device link connected with the devices is also reset; if not, the error can be corrected, the working state of the message sending source is checked, and finally the error of each device is cleared.
Based on the above technical scheme, this scheme still includes:
and generating a log file corresponding to the PCIE fault format event.
Specifically, for example, specific information of a failure occurring in a PCIE link is clearly known, and a log file corresponding to a PCIE failure format event is generated; the log file at least comprises the event type, the event occurrence frequency, the event occurrence time, the event processing and other detailed information.
