Abstract
The invention provides a method for managing a watchdog in a user mode. The method is characterized by comprising: S1, acquiring equipment information in the process of starting the user mode; S2, sending the equipment information to an inner core which starts a corresponding watchdog according to the equipment information. According to the method, the debugging difficulty is effectively reduced and the debugging efficiency is improved.
Description
Technical field
The present invention relates to network communication technology field, under particularly relating to a kind of User space, manage the method for watchdog.
Background technology
Watchdog(hardware watchdog) be utilize a timer circuit, its timing output is connected to the reset terminal of circuit, program resets (being commonly called as " feeding dog ") timer within the scope of certain hour, therefore when program normally works, timer always can not overflow, and also just can not produce reset signal.If program malfunctions, do not reset house dog in timing cycle, just makes WatchDog Timer overflow to produce reset signal to lay equal stress on starting system.
But because hardware is diversified, the hardware implementation mode of watchdog is closely not identical yet, what have passes through GPIO(GeneralPurposeInputOutput, universal input/output) realize, have by IO(I/O) bus realize, what have passes through CPLD(ComplexProgrammableLogicDevice, CPLD) realize etc., therefore can only for each hardware, the enable different types of watchdog of initialization, or for different hardware, compile different system versions and carry out adaptation, and comparatively bother from kernel state adjustment.
Summary of the invention
In order to strengthen the environment that watchdog is suitable for, manage the method for watchdog under the present invention proposes a kind of User space, concrete scheme is as follows:
Manage a method of watchdog under User space, it is characterized in that, described method comprises:
S1, in the process starting User space, obtains facility information;
S2, sends to kernel by described facility information, and kernel enables corresponding watchdog according to described facility information.
Preferably, described acquisition facility information is specially: the chipset information of fetch equipment, and equipment information.
Preferably, kernel is sent to be specially described facility information: by ioctl function, described facility information to be sent to kernel.
Preferably, described facility information is product form and the sub-form of product.
Preferably, also comprised before step S1: S0, when starting kernel state, do not enable watchdog.
Preferably, also comprise after step S1: S3, by sending the operational order control watchdog of watchdog to kernel state under User space.
The present invention by mutual to facility information of kernel state and User space, thus carries out unified management to the diversified equipment of hardware, and implementation platformization manages, and can operate watchdog under User space, reduces the difficulty of debugging, makes flexibility ratio higher.
Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Manage the method for watchdog under a kind of User space provided by the invention, concrete grammar is as described below:
S0, when starting kernel state, does not enable watchdog.
When system starts kernel state, first do not enable watchdog, i.e. first not enable watchdog, but directly start User space.
S1, in the process starting User space, obtains facility information.
After system starts kernel state, when starting User space, obtain facility information, wherein, described facility information is specially product form and the sub-form of product.Be specially, in the process of program starting User space, by equipment interface (as: PCI etc.), the chipset information of fetch equipment, and equipment information, the i.e. product form (as: industrial computer hardware, hardware server, virtual machine etc.) of equipment and the sub-form of product (as: 10G platform industrial computer, 20G platform industrial computer, 40G platform industrial computer etc.).
S2, sends to kernel by described facility information, and kernel enables corresponding watchdog according to described facility information.
After the User space of system gets facility information, facility information is sent to kernel, kernel, according to the facility information obtained, enables corresponding watchdog, i.e. the watchdog of enable correspondence.Be specially, facility information is obtained in the program of User space, by ioctl function, described facility information is sent to kernel, send out message to system kernel by product form and the sub-form of product, after kernel obtains product form and sub-form, enable corresponding watchdog, and open the monitoring function of watchdog, start simultaneously and feed dog timer, timing carries out dog feeding operation, the normal operation of keeping system.
S3, by sending the operational order control watchdog of watchdog to kernel state under User space.
Can also by operational order row under User space, send to close to kernel state and feed dog timer, by operations such as the enable closedowns of watchdog, realize the object of User space control watchdog flexibly, for the debugging of researching and developing and location.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of the claims in the present invention.
