Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
Referring to fig. 1, a flowchart illustrating steps of a display method according to a first embodiment of the present invention may specifically include the following steps:
and step 101, adding the attribute identification information of the display acquired in advance into display driving source codes of the operating system kernel, and compiling to generate a binary file of the operating system kernel.
The attribute identifying information of the display includes, but is not limited to, EDID information and the like for enabling a computer or other image output apparatus to better identify the attribute of the display, which is not limited in the embodiment of the present invention. EDID information refers to screen resolution data containing parameters related to the display and its capabilities, such as character strings including vendor information, maximum image size, color settings, vendor presets, frequency range limits, and display name and serial number, etc.; typically, the EDID information is present in a PROM (Programmable read-only memory ) or EEPROM (Electrically Erasable Programmable read only memory, electrically erasable programmable read-only memory) of the display. If EDID information is to be read, it can be implemented by DDC via I2C bus (a simple, bi-directional two-wire synchronous serial bus).
The operating system kernel is the core part of most operating systems. It consists of parts of the operating system that are used to manage memory, files, peripherals, and system resources. The operating system kernel is capable of running processes and providing inter-process communication. Specifically, in a computer architecture, some programs that are closely related to hardware are often separated, and the separated programs are called operating system kernels. The method comprises a driver, wherein the driver is a special program which can enable a computer and equipment to communicate with each other; the driver program comprises a display driver for driving the display card device, so that the display is driven to display after the display card device converts the information to be displayed.
In the embodiment of the invention, when the attribute identification information of the display cannot be acquired in a special scene, for example, when the display is accessed remotely, the attribute identification information of the display cannot be acquired, and at the moment, the problem that the display card cannot identify the display is caused, so that the display cannot normally display the information; therefore, the attribute identification information of the display needs to be acquired in advance, and in particular, the attribute identification information of the display can be acquired by a short-distance access mode. And then, in order to facilitate the identification and processing of the attribute identification information of the display by the operating system, adding the attribute identification information acquired in advance into the display driving source code, and compiling the display driving source code to generate a binary file of an operating system kernel. The display driver source code refers to source code of a display driver, and the binary file is a file of display driver data and instructions which can be used on an operating system through compiling. For example, a compiler is used to compile the display driver source code to obtain a corresponding binary file.
In the embodiment of the present invention, the attribute identifying information of the display acquired in advance is added to the display driving source code of the operating system kernel, and the step of generating the binary file of the operating system kernel through compiling may be performed on the target device, may be performed on the device that acquires the attribute identifying information of the display in advance, or may be performed on any other suitable device, which is not limited in the embodiment of the present invention. The target device is a device that cannot obtain the EDID through the DDC, for example, the target device is a device that is remotely connected to the display, and the target device may include a computer or other image output device, or any other suitable device, which is not limited in this embodiment of the present invention.
And 102, updating the binary file into an operating system of the target device.
In the embodiment of the present invention, the generated binary file includes attribute identification information of the display; based on this, the generated binary file is updated into the operating system of the target device, and when step 101 is executed on the target device, the binary file may be directly updated into the operating system; implementations of updating the binary file into the operating system of the target device when step 101 is performed on another device may include, for example, transmitting the binary file to the target device over a network, or copying the binary file to the target device for use by the operating system, or any other suitable implementation, as the embodiments of the present invention are not limited in this respect.
In the embodiment of the invention, in the operating system of the target device, the attribute identification information of the display is not acquired in a conventional manner, for example, the EDID information of the display is acquired through the DDC. But rather saves the attribute identification information present in the binary file to the target cache based on the data and instructions in the binary file. The target cache refers to an area for displaying and storing attribute identification information in an operating system of the target device, and the position of the target cache in the memory is generally determined by display driver source codes.
The DDC generally includes a central control device (such as a central control computer, a color monitor, a keyboard, a printer, an uninterruptible power supply, a communication interface, etc.), a field DDC controller, a communication network, and corresponding components such as a sensor, an actuator, and a regulating valve. The DDC controller is the core of the whole hardware control system and is a key component for realizing the control function of the hardware control system. The DDC is a channel for transmitting EDID information, but there is a problem in that EDID information cannot be acquired through the DDC when a display is remotely accessed.
And 104, displaying on a display of the target equipment according to the attribute identification information in the target cache.
In the embodiment of the invention, when the display accessed by the target equipment is displayed, the attribute identification information can be extracted from the target cache, and the target equipment can output the information to be displayed to the display for displaying according to the attribute identification information.
According to the embodiment of the invention, the attribute identification information of the display is added into the display drive source code of the kernel of the operating system, the binary file of the kernel of the operating system is generated through compiling, the binary file is updated into the operating system of the target device, the attribute identification information is stored into the target cache according to the binary file in the operating system of the target device, and the display is carried out on the display of the target device according to the attribute identification information in the target cache, so that the attribute identification information of the display cannot be obtained even when the target device is remotely accessed into the display, the problem that the display cannot normally carry out display output or does not carry out display output is solved, and the operation stability of the target device accessed into the display is improved; furthermore, in an application scene with a plurality of target devices, the plurality of target devices can use the same binary file to obtain the attribute identification information at the same time, so that the efficiency of obtaining the attribute identification information by the plurality of target devices is improved.
Referring to fig. 2, a flowchart illustrating steps of a display method according to a second embodiment of the present invention may specifically include the following steps:
step 201, searching the attribute identification information of the display driver cache of the assisting equipment, and outputting the searched attribute identification information to a kernel log of the assisting equipment.
In the embodiment of the invention, the assisting equipment is relative to the target equipment, and the assisting equipment can acquire the attribute identification information; the assisting equipment acquires attribute identification information of the display in advance by accessing the display in a short distance. And the assisting equipment is provided with a chip with the capability of acquiring the attribute identification information. For example, data and instructions are exchanged directly with the processor, acting as a processing chip, also called a bridge, connected to the bridge, which is designed as a bridge that can acquire attribute identification information.
The assisting device obtains the attribute identification information of the display through the bridge piece, and the display accessed by the assisting device is not necessarily the same display as the display accessed by the target device, but is necessarily the same model or at least the same display as the attribute identification information. The acquired attribute identification information is firstly stored in a cache of the assisting equipment, and the cache storing the attribute identification information is marked as a display driving cache; and outputting the acquired attribute identification information to a kernel log of the assisting equipment.
In the embodiment of the present invention, optionally, one implementation manner of outputting the searched attribute identification information to the kernel log of the assisting device includes: and printing the attribute identification information into the kernel log.
The kernel log is actually a part of the memory in the kernel, and is used for recording the information about the kernel which cannot be written into the disk, because the information is generated before the file system is loaded, and the attribute identification information belongs to the information; based on the particularity of the kernel log, the attribute identification information can be output to the kernel log in a kernel printing mode. It may appear that the kernel log may be implemented by a printk function, which has a similar effect as the user space corresponding function printf (print by format). In the kernel, a printk (print kernel) can write a formatted message into a cache of a memory using a format almost identical to a printf function.
In the concrete implementation, the display driving cache for storing the attribute identification information is found by reading the kernel code, and the kernel code is recompiled by modifying the kernel code; and putting the recompiled file into an operating system; and (3) placing the operating system on the assisting equipment for running, starting the assisting equipment, and printing attribute identification information into a kernel log of the assisting equipment according to the recompiled kernel code after the operating system runs normally.
In the embodiment of the invention, the attribute identification information is extracted from the kernel log and stored, for example, in a file form.
And 203, adding the attribute identification information of the display acquired in advance into display driving source codes of the operating system kernel, and compiling to generate a binary file of the operating system kernel.
In the embodiments of the present invention, the specific implementation manner of this step may be referred to the description in the foregoing embodiments, which is not repeated herein.
And step 204, updating the binary file into an operating system of the target device.
In the embodiments of the present invention, the specific implementation manner of this step may be referred to the description in the foregoing embodiments, which is not repeated herein.
In the embodiment of the present invention, since the target device cannot acquire the attribute identification information from the display, in order to keep the hardware state of the target device consistent with the software state of the operating system on the target device, it is necessary that the operating system controlling the target device does not perform the operation of acquiring the attribute identification information through the Direct Digital Controller (DDC). For example, before the binary file is generated by compiling, in the display driver source code, a sentence for obtaining the EDID information by the DDC is found and annotated, so that the operation system of the target device will not perform the operation for obtaining the attribute identification information by the direct digital controller in accordance with the binary file obtained after compiling.
And 206, storing the attribute identification information in the binary file into a target cache.
In the embodiment of the invention, in order to use the attribute identification information on the target device, the attribute identification information in the binary file needs to be stored in the target cache.
In an embodiment of the present invention, optionally, in an implementation manner of adding the attribute identification information of the display acquired in advance to the display driving source code of the operating system kernel and generating the binary file of the operating system kernel through compiling, the method may include: storing the attribute identification information in the display drive source code in an array form; adding a copy instruction of the attribute identification information to the display drive source code; compiling a source code containing the attribute identification information and the copy instruction stored in an array form to generate a binary file of the operating system kernel; accordingly, according to the binary file, the implementation manner of saving the attribute identification information into the target cache may include: acquiring a copy instruction and the attribute identification information in the binary file; and storing the attribute identification information into a target cache according to the copy instruction.
The copy instruction is an instruction for copying the attribute identification information into the target cache. That is, when the attribute identification information is added to the display driver source code, the attribute identification information is stored in an array form, and in order to store the attribute identification information in the binary file into the target cache, a copy instruction is also required to be added to the display driver source code, and after the binary file is generated by compiling, the copy instruction can be executed according to the binary file.
For example, EDID information stored in a file is added to the display driver source code; when the EDID information is 128 bytes, the corresponding preferred mode is that the array is also designed into 128-byte numbers, the added EDID information is stored in the display drive source code in the form of 128-byte arrays, the display drive source code is modified, and a copy instruction is added; the copying instruction is an instruction for copying the EDID information stored in the array into a target cache; and compiling the display drive source code added with the EDID information and the copy instruction to generate a binary file of the operating system kernel. After the operating system of the target device is started, according to the data and the instructions in the binary file, the EDID information in the binary file is stored in the target cache.
And step 207, displaying on a display of the target device according to the attribute identification information in the target cache.
In the embodiments of the present invention, the specific implementation manner of this step may be referred to the description in the foregoing embodiments, which is not repeated herein.
According to the embodiment of the invention, the attribute identification information of the display driving cache of the assisting equipment is searched, the searched attribute identification information is output to the kernel log of the assisting equipment, the attribute identification information in the kernel log is stored, the attribute identification information is printed to the kernel log, the attribute identification information of the display acquired in advance is added to the display driving source code of the operating system kernel, the binary file of the operating system kernel is generated through compiling, the binary file is updated to the operating system of the target equipment, the operating system of the target equipment is controlled not to execute the operation of acquiring the attribute identification information through a direct digital controller according to the binary file, the attribute identification information in the binary file is stored in the target cache, and the attribute identification information of the display of the target equipment is displayed on the display of the target equipment according to the attribute identification information in the target cache, so that the attribute identification information of the display cannot be obtained even when the target equipment is remotely accessed to the display, and the problem that the display cannot normally output or the display cannot be output is solved or the operation stability of the target equipment is not accessed to the display is improved is solved; furthermore, in an application scene with a plurality of target devices, the plurality of target devices can use the same binary file to obtain the attribute identification information at the same time, so that the efficiency of obtaining the attribute identification information by the plurality of target devices is improved.
