Background
With the rapid development of science and technology, people have higher and higher requirements for the functions of intelligent devices, for example, compared with a common gateway, the current intelligent gateway has various plug-in functions such as "checking networking users", "restricting user from surfing the internet", and the like, so that a large number of plug-ins are usually integrated on the intelligent devices, various plug-in libraries need to be loaded during operation, and more DDR (Double Data Rate, Double Data synchronous dynamic random access memory) resources of the intelligent devices are occupied.
Taking the intelligent gateway as an example, the intelligent gateway consumes more than ten and several million DDR resources than the common gateway, and because the common gateway adopts more 128M DDR, the memory resource of the intelligent gateway needs to be increased by multiple, namely 256M DDR, which increases the cost.
Before leaving the factory, the intelligent gateway is programmed according to a system image file which is manufactured in advance, a physical memory (namely a storage memory) of the intelligent gateway is used for storing a programmed system program file, the programmed intelligent gateway can be used, and the system file is loaded from the storage memory to an operating memory (namely DDR) after the intelligent gateway is started. In the existing intelligent gateway, all the dynamic libraries of the plug-ins are all loaded on the DDR at one time along with the system file, because the positions of the dynamic libraries of the plug-ins in the system image file are random when the system image file is generated, and in order to improve the safety, the system program file containing the dynamic libraries of the plug-ins is of a read-only type, the dynamic libraries of the plug-ins on the DDR can not be deleted or repeatedly loaded and the like.
On the other hand, the intelligent gateway generally has a remote upgrade function, and even if there is no upgrade task currently, sufficient DDR resources are reserved for caching upgrade files, and this space is completely used when the intelligent gateway is in normal operation.
In summary, the DDR resources of the existing smart devices cannot be reasonably utilized, and the resource loading and allocating manner is not flexible.

First, the intelligent gateway is briefly introduced from two aspects:
in a first aspect: burning process of the intelligent gateway;
the intelligent gateway burns according to the manufactured image file, and can be understood as copying the image file into the storage memory. The mirror image file is a plug-in dynamic library which comprises an embedded system program operated by the intelligent gateway and various plug-ins, and can be started to use after burning is finished.
After the intelligent gateway is started, all the image files in the storage memory are loaded into the DDR (double data rate) of the operation memory at one time, and after the loading of the intelligent gateway is completed, various functions and plug-ins are operated, namely, the image files directly determine the working mode of the intelligent gateway. The following introduces the relevant contents of the image file produced by the embodiment of the present invention:
as shown in fig. 2, which is a schematic view of a partition architecture of an image file provided in an embodiment of the present invention, a system program is placed in a Flash partition 1, and a plug-in is placed in a Flash partition 2, in the present invention, the content of the Flash partition 2 is not involved, the function of the Flash partition 2 is generally two independent manufacturing parts with the system program, and finally, an integration process is performed, so the following description focuses on a complete flow of generating an image file by the Flash partition 1:
Dividing the Flash partition 1 into a system program area, a filling area and a plug-in LIB (LIB, a file name suffix) area according to preset address parameters, wherein an embedded system file of an intelligent gateway is stored in the system program area; a plug-in dynamic library is stored in the plug-in LIB area; the filling area is obtained by calculation according to the set storage address of the plug-in LIB area and the memory size of the system program area, and is used for filling between the system program area and the plug-in LIB area to ensure that the initial storage address of the plug-in LIB area is fixed.
And respectively manufacturing files in the system program area, the filling area and the plug-in LIB area into a system image file, a filling image file and a plug-in dynamic library image file.
For example, the following steps are carried out:
creating a folder named filesystem in a system program area, storing an embedded system used by an intelligent gateway into a filesystem directory of the system program area according to a preset directory structure, removing a plug-in dynamic library in subfolders/LIBs/glib used for storing a plug-in dynamic library in the filesystem directory, cutting the plug-in dynamic library into a temporary folder temp/glib in the filesystem1 of a plug-in LIB area, establishing a soft link pointing to the temporary folder temp/glib in the filesystem1 at the original/LIB/glib position in the filesystem, and making the filesystem into a system mirror image file system.bin by using a mirror image tool;
As shown in fig. 3, the offset of the LIB area of the plug-in the Flash partition 1 is set to 16M, and the filesysem 1 in the LIB area of the plug-in is made into a plug-in dynamic library image file glib.
Because the offset of the LIB area of the plug-in is 16M, assuming that the memory occupied by the system image file is calculated to be 12.3M, the size of the filling area can be calculated to be 3.7M according to the offset of the system image file and the LIB area of the plug-in, that is, 3.7M of memory space is left between the system image file system.bin and the plug-in dynamic library image file glib.bin, and a mirror image tool is used to generate a 3.7M empty file as the filling image file pad.bin.
The system image file system.bin, the filling image file pad.bin and the plug-in dynamic library image file glib.bin are used for generating a total image file packet clinux.bin by using a command cat system.bin pad.bin glib.bin > tclinux.bin, and the offset of the plug-in dynamic library image file glib.bin in the total image file packet tclinux.bin is 16M.
Note that the temporary folder temp/glib in filesystems 1 is of a read-write type. Due to the limitation of authority, the system program file is read-only, the content in the system program cannot be modified such as increased, decreased or moved, the dynamic library file of the plug-in is contained in the original system program file, but the position of the dynamic library of the plug-in the system program file is not fixed, so that the deletion and the repeated loading of the dynamic library of the plug-in cannot be realized if the original system program file is used. The embodiment of the invention respectively packs the system program file and the plug-in dynamic library based on the content of the original system program file to generate the mirror image file, and realizes the deletion and repeated loading of the plug-in dynamic library in the temporary folder because the temporary folder is of a readable and writable type.
The process is a complete process for manufacturing the image file, the total image file package is used for burning the intelligent gateway, and the intelligent gateway can be started to use after burning is completed. The operation of the intelligent gateway is described in the second aspect.
In a second aspect: the operation process of the intelligent gateway;
1, starting up and loading:
after starting up, loading tclinux.bin in a memory into a DDR, firstly, reading a partition header of a system partition by a boot (loading operating system) according to a traditional Flash loading mode, wherein the partition header comprises memory size information and offset information of kernel and rootfs, dividing tclinux.bin into kernel and rootfs (file system) according to related information in the partition header, and loading 12.3M system.bin into the DDR according to the traditional loading mode because the header of the system partition is also the header of the system.bin; bin is the data from the offset 16M of the system area to the end of the system program area, and before the plug-in is started, bin needs to be loaded into/temp/glib in DDR.
2, system upgrading process:
in the system upgrading task, the plug-in is required to be closed, then the plug-in dynamic library in the temporary folder temp on the DDR is deleted, and the released DDR resource is used for storing the upgrading data packet required by the system upgrading.
It should be noted that the temporary folder on the DDR is compatible with the security and the read-write function, the dynamic library of the plug-in can be released quickly, and the plug-in function is stopped in advance, so that the embedded system will not crash even after the dynamic library of the plug-in is deleted, and the released DDR resources can be used to download the upgrade data packet, thereby realizing the multiplexing of the DDR resources.
For example, the following steps are carried out:
and the/temp/glib on the DDR is a plug-in dynamic library loaded from glib.
After determining that the plug-in meets the idle condition, the intelligent network can delete the plug-in dynamic library, and store the upgrade data packet or cache for other functions by using the released DDR resource, for example, using the released DDR resource as the cache of Wi-Fi. Among them, there are many possibilities to satisfy the idle condition of the plug-in, which are described below:
The first idle condition is as follows: the plug-in state is a closed state;
and when the intelligent gateway detects that the plug-in is in a closed state, determining that the idle condition of the plug-in is met.
And (2) idle condition two: the non-operation time of the plug-in reaches the preset time;
such as: and setting the non-operation time of the plug-in unit meeting the idle condition to be 10min (minutes), and after the non-operation time of the plug-in unit is checked to reach 10min, determining that the plug-in unit meets the idle condition.
It should be noted that, if there is one plug-in the intelligent gateway, it is only necessary to determine whether the plug-in meets the idle condition, and if there are multiple plug-ins in the intelligent gateway, after detecting which plug-in meets the idle condition, the dynamic library of the plug-in corresponding to the plug-in is deleted.
For example, the following steps are carried out: assume that there are 3 plug-in dynamic libraries: the plug-in dynamic library 1, the plug-in dynamic library 2 and the plug-in dynamic library 3 are respectively loaded into a/temp/glib 1,/temp/glib 2 and/temp/glib 3 of the DDR, and if the plug-in dynamic library 1 is detected to meet an idle condition, the/temp/glib 1 of the DDR is deleted; and deleting the DDR/temp/glib 2 if the plug-in dynamic library 2 is detected to meet the idle condition, and the like.
It should be noted that, in addition to system upgrade, after determining that a plug-in meets an idle condition, the intelligent network may use the removed dynamic library of plug-ins to use the released DDR resources as a cache of other functions, for example, the more DDR the Wi-Fi function in the intelligent gateway runs, the better the performance is, therefore, the embodiment of the present invention may also allocate the removed dynamic library of plug-ins to the Wi-Fi function using the released DDR resources as a cache of Wi-Fi.
3, reloading the plug-in dynamic library:
when the condition of running the plug-in is detected to be met, the running environment of the plug-in needs to be recovered because the plug-in dynamic library is deleted, and the method comprises the following specific steps: deleting the upgrade data packet on the DDR, and reloading the deleted plug-in dynamic library to the DDR according to the storage address parameter of the plug-in dynamic library in the storage memory.
For example, the following steps are carried out: after the condition that the plug-in meets the plug-in operation condition is checked, firstly deleting a/temp/packet folder for storing an upgrading data packet on the DDR, determining a glib.bin file according to the offset 16M of the LIB partition of the plug-in the Flash partition 1, reloading the glib.bin into the/temp/glib of the DDR, and at the moment, restarting the plug-in. Among them, there are many possibilities to satisfy the operation condition of the plug-in, which are described below:
the operating conditions are as follows: the system upgrading is finished;
after the upgrade data packet is downloaded, the upgrade data packet is not verified, and olt (optical line terminal) does not issue an upgrade implementation instruction; or
After downloading the upgrading data packet, receiving a system upgrading cancelling instruction; or after the system upgrading is finished by using the downloaded upgrading data packet, the system upgrading is considered to be finished.
And (2) operating conditions are as follows: receiving a plug-in starting instruction;
for example, after receiving the plug-in starting instruction, the operating condition of the plug-in is considered to be satisfied.
In a general situation, the library file is released and reloaded, which can only be used in an operating system with complete memory management, such as a server and a PC, and is equivalent to a SWAP cache of the operating system, and an embedded system does not have a SWAP cache, but in an intelligent gateway, a plug-in dynamic library file is characterized in that a plug-in dynamic library is not changed in the running process of the intelligent gateway, so that setting a fixed offset of the plug-in dynamic library in a storage memory to load the plug-in dynamic library file is equivalent to realizing a SWAP cache function of a large operating system.
Based on the same concept, as shown in fig. 4, an embodiment of the present invention provides an apparatus for loading data, including: a processor 400 and a memory 401, wherein the memory 401 stores program code, and wherein one or more computer programs stored in the memory 401, when executed by the processor 400, cause the apparatus to perform the following:
deleting the plug-in dynamic library of the plug-in meeting the idle condition from the running memory after the plug-in meets the idle condition and needs to be upgraded; loading an upgrade data packet into the operating memory; deleting the upgrading data packet in the running memory after the plug-in meets the running condition; and acquiring the deleted dynamic plug-in library from the storage memory and loading the deleted dynamic plug-in library into the running memory according to the storage address parameter of the dynamic plug-in library in the storage memory.
Optionally, the processor 400 is specifically configured to:
acquiring a mirror image file containing the dynamic plug-in library from a storage memory according to the storage address parameter of the dynamic plug-in library in the storage memory;
