Fig. 1 is a schematic block diagram of an example computing device 100.
As shown in FIG. 1, in a basic configuration 102, a computing device 100 typically includes a system memory 106 and one or more processors 104. The memory bus 108 may be used for communication between the processor 104 and the system memory 106.
Depending on the desired configuration, the processor 104 may be any type of processing including, but not limited to: a microprocessor (UP), a microcontroller (UC), a digital information processor (DSP), or any combination thereof. The processor 104 may include one or more levels of caches, such as a first level cache 110 and a second level cache 112, a processor core 114, and registers 116. The example processor core 114 may include an Arithmetic Logic Unit (ALU), a Floating Point Unit (FPU), a digital signal processing core (DSP core), or any combination thereof. The example memory controller 118 may be used with the processor 104, or in some implementations, the memory controller 118 may be an internal part of the processor 104.
Depending on the desired configuration, system memory 106 may be any type of memory including, but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. The system memory 106 may include an operating system 120, one or more applications 122, and program data 124. In some implementations, the application 122 may be arranged to execute instructions on an operating system by the one or more processors 104 using the program data 124.
Computing device 100 may also include a storage interface bus 134. Storage interface bus 134 enables communication from storage devices 132 (e.g., removable storage 136 and non-removable storage 138) to base configuration 102 via bus/interface controller 130. At least a portion of the operating system 120, applications 122, and data 124 may be stored on removable storage 136 and/or non-removable storage 138, and loaded into the system memory 106 via the storage interface bus 134 and executed by the one or more processors 104 when the computing device 100 is powered up or the application 122 is to be executed.
Computing device 100 may also include an interface bus 140 that facilitates communication from various interface devices (e.g., output devices 142, peripheral interfaces 144, and communication devices 146) to basic configuration 102 via bus/interface controller 130. The example output device 142 includes a graphics processing unit 148 and an audio processing unit 150. They may be configured to facilitate communication with various external devices such as a display or speakers via one or more a/V ports 152. Example peripheral interfaces 144 may include a serial interface controller 154 and a parallel interface controller 156, which may be configured to facilitate communication with external devices such as input devices (e.g., keyboard, mouse, pen, voice input device, touch input device) or other peripherals (e.g., printer, scanner, etc.) via one or more I/O ports 158. An example communication device 146 may include a network controller 160, which may be arranged to facilitate communication with one or more other computing devices 162 via one or more communication ports 164 over a network communication link.
The network communication link may be one example of a communication medium. Communication media may typically be embodied by computer readable instructions, data structures, program modules, and may include any information delivery media in a modulated data signal, such as a carrier wave or other transport mechanism. A "modulated data signal" may be a signal that has one or more of its data set or changed in such a manner as to encode information in the signal. By way of non-limiting example, communication media may include wired media such as a wired network or special purpose network, and wireless media such as acoustic, radio Frequency (RF), microwave, infrared (IR) or other wireless media. The term computer readable media as used herein may include both storage media and communication media.
Computing device 100 may be implemented as a personal computer including desktop and notebook computer configurations. Of course, computing device 100 may also be implemented as part of a small-sized portable (or mobile) electronic device such as a cellular telephone, a digital camera, a Personal Digital Assistant (PDA), a personal media player device, a wireless web-watch device, a personal headset device, an application-specific device, or a hybrid device that may include any of the above functions. And may even be implemented as servers, such as file servers, database servers, application servers, WEB servers, and the like. The embodiments of the present invention are not limited in this regard.
In an embodiment in accordance with the invention, computing device 100 is configured to perform operating system boot method 200 in accordance with the invention. Wherein the computing device 100 contains a plurality of program instructions for executing the operating system boot method 200 according to the present invention, such that the operating system boot method 200 of the present invention can be executed in the computing device.
FIG. 2 illustrates a flowchart of an operating system boot method 200 according to one embodiment of the invention. It should be noted that, in the embodiment of the present invention, the operating system boot method of the present invention is described in detail only with the Live operating system as the target operating system, but the operating system boot policy of the present invention is not limited to the Live operating system.
It should be noted that the storage device (e.g., hard disk) local to the computing device 100 includes a local operating system, such as, but not limited to, a Linux operating system. According to the method 200 of the present invention, the target operating system may be stored and booted in the computing device 100 with the local operating system installed, the storage of the target operating system being independent of a storage medium external to the computing device.
As shown in fig. 2, the method 200 begins at step S210. In step S210, the boot item of the target operating system is booted so as to boot the boot of the target operating system based on the boot item of the target operating system. In one embodiment, the target operating system may be a Live operating system.
It should be noted that the Live operating system is a minimized Linux kernel-based operating system. In the prior art, the Live operating system needs to be stored based on a storage medium outside the computing device, and the storage medium where the Live operating system is located needs to be designated as a boot disk for starting the Live operating system.
According to one embodiment of the invention, a target root file system corresponding to a target operating system (Live system) is pre-built, a corresponding compressed file is generated based on the target root file system, and for example, the target root file system can be compressed based on squarfs-tools to generate a squarfs file. The compressed file squaresfs for the target root file system is then stored in the local operating system of the computing device 100. In this way, storing the compressed file of the Live operating system in a storage device local to the computing device is achieved, without relying on additional storage media to store the Live operating system.
In addition, according to one embodiment, after the target root file system is built, the boot items of the target operating system are also configured based on the boot manager. Specifically, the kernel and temporary root file system for starting the designated target operating system are respectively the same as the kernel and temporary root file system of the local operating system. That is, the kernel that designates the target operating system to start is the same file as the kernel of the local operating system, and the temporary root file system that designates the target operating system to start is the same file as the temporary root file system of the local operating system. The path of the target root file system (corresponding to its corresponding location where the compressed file is stored in the local operating system) is specified, so that the compressed file of the target root file system can be obtained based on the corresponding path when the target operating system is started. And, the specified operating system boot program is a boot program corresponding to the target operating system so as to boot the target operating system (Live system) on the basis of a boot method corresponding to the target operating system.
Here, the boot manager may be implemented as Syslinux, GRUB, GRUB Legacy, lio, etc., but it should be noted that the present invention is not limited to the specific kind of boot manager.
In one embodiment, the target operating system boot may be directed based on the GRUB boot manager. It should be noted that the main configuration file of the GRUB boot manager is/boot/GRUB. The GRUB/etc/grub.d directory contains all the scripts that GRUB needs to use, which are the basis for creating grub.cfg. When configuring the boot items of the target operating system based on the GRUB boot manager, the configuration file/boot/GRUB/grub.cfg of the GRUB is updated based on the script in the grub.d folder. Specifically, the startup item of the Live system is added by adding a script in the grub.d folder, and the added startup item is the configured startup item corresponding to the target operating system. That is, a corresponding script file is generated based on configuration information such as a kernel, a temporary root file system, a boot mode and the like of the designated target operating system boot, the script file is added to the per-etc/grub.d directory, and the boot item of the target operating system is configured in the GRUB boot manager through updating the per-boot/GRUB/grub.cfg file.
Based on this, the target operating system may be started based on the local disk, specifically, the startup manager at the local disk selects a startup item of the startup and target operating system to start the target operating system. When the target operating system is started based on the specified boot file, the starting item of the target operating system is started, and the starting of the target operating system is guided through the kernel of the local operating system and the temporary root file system, so that the Live operating system is started from the local operating system. See in particular the relevant description of the following steps.
In step S220, the kernel and temporary root file system of the local operating system are loaded into memory. It should be noted that by loading the kernel of the local operating system, the target operating system may use the kernel of the local operating system to implement sharing the kernel with the local operating system. By loading the temporary root file system of the local operating system, the root file system of the local operating system can be mounted.
Specifically, after loading the kernel of the local operating system and the temporary root file system into the memory, a virtual root file system is generated in the memory based on the temporary root file system (initrimfs) of the local operating system. Furthermore, the real root file system of the local operating system is mounted based on the virtual root file system, so that the mounting of the root file system of the local operating system is realized. Here, the first process/sbin/init of Linux may be invoked after the real root file system is mounted.
It is understood that the temporary root file system is a memory-based file system. In one embodiment, the temporary root file system may be implemented as an initumfs, for example.
After the real root file system of the local operating system is mounted, according to the mounted real root file system, the compressed file corresponding to the target root file system stored in the local operating system can be acquired based on the corresponding path.
Subsequently, in step S230, the compressed file corresponding to the target root file system is loaded into the memory, so as to mount the target root file system. The target root file system can be called by the target operating system through mounting the target root file system.
After the target root file system is mounted, step S240 may be performed. In step S240, based on the root file system of the installed local operating system, one or more kernel modules required by the local operating system in the starting process are copied to the target root file system in the memory. In this way, the target operating system may call these kernel modules in the target root file system, so that the target operating system may call the same kernel modules as the local operating system during the boot process.
It should be noted that the kernel module in the temporary root file system (initrimfs) of the local operating system only includes some necessary hardware drivers for the operating system to boot, and other kernel modules required during the booting process, such as a graphics video card, a sound card, etc., are all stored in the/lib/modules directory. Thus, in one embodiment, the present invention enables copying one or more kernel modules required by the local operating system during boot-up to the target root file system in memory by copying content (including one or more kernel modules) in the root file system of the local operating system to the same directory in the target root file system of the target operating system.
According to one embodiment, during the initialization phase of the temporary root file system, the content (including one or more kernel modules) under the local operating system/lib/modules directory is copied to the corresponding directory in the target operating system. Thus, based on the real root file system of the mounted local operating system, the target operating system can call one or more kernel modules under the corresponding directory in the target operating system, namely, the kernel module same as the local operating system, so that the kernel module which is required in the starting process shared with the local operating system is realized. Based on the method, the sharing of the kernel modules can be realized, namely, one or more kernel modules required by the local operating system in the starting process are used for starting the target operating system.
In one embodiment, the one or more kernel modules include, but are not limited to, drives for USB, SATA, SCSI hard disks and drives for LVMs, RAID file systems, for example.
After copying the next kernel module or modules of the/lib/modules directory into the corresponding directory of the target root file system in memory, the root file system of the local operating system may be uninstalled.
In summary, according to the operating system startup method of the present invention, the Live operating system is stored by storing the compressed file of the Live operating system in a storage device local to the computing device, without relying on an additional storage medium. According to a pre-configured starting item of a target operating system, when the target operating system is started, the starting of the target operating system is guided through a kernel and a temporary root file system of a local operating system, so that the starting of a Live operating system is guided from the local operating system, and the Live operating system can share the kernel with the local operating system. In addition, the invention copies one or more kernel modules required by the local operating system in the starting process into the target root file system in the memory, so that the target operating system can call the kernel module the same as the local operating system in the starting process. In this way, the invention realizes that the Live operating system shares the kernel module with the local operating system, and the target operating system is started by using one or more kernel modules required in the starting process of the local operating system.
