Description
Technical Field
The invention relates to the technical field of computers, in particular to a hardware isolation-based hybrid virtualization model, electronic equipment and a vehicle cabin.
Background
Currently, with the performance of a nanoscale System On Chip (SOC) becoming higher and higher, a single SOC often causes excessive hardware capability when running a single operating System. To avoid the hardware capability excess of an SOC, multiple systems, i.e., multi-system solutions, may be run in one SOC. In particular, for example, in the field of intelligent cabins, multi-system solutions fully exploit the performance of the SOC and are able to meet the experience of users in different areas within the cabin. The existing multi-system solutions are diverse and each has advantages and disadvantages. For example, lightweight kernel virtualization (LXC) is the weakest in isolation and the best in sharing performance; hypervisor virtualization technology isolation and sharing performance is centered; hardware isolated multisystem solutions are the most isolated and the least shared (lack of open-source device sharing solutions).
To avoid the problems with existing multi-system solutions, some manufacturers have proposed a dual SOC solution under the intelligent cabin, specifically connecting the two SOCs via a high-speed bus. Although the central processing unit (Central Processing Unit, abbreviated as CPU) and peripheral performance of a single SOC are general, the performance weakness can be made up by increasing the number and the problem of device sharing can be solved. While high speed communication is possible between SOCs in a dual SOC solution, the high number of peripheral dual backups necessarily drives up hardware costs, not meeting the initiative of a multi-system solution. And, the problem of device sharing between SOC internal systems is not fundamentally solved.

FIG. 2 is a schematic architecture diagram of a hardware isolation based hybrid virtualization model according to another embodiment of the present invention; fig. 3 is a flow chart of a method of audio virtualization of a hybrid virtualization model, according to one embodiment of the present invention. The audio virtualization of the hardware-based hybrid virtualization model 100 of the present invention is described in detail below in conjunction with fig. 2 and 3. The example is applicable to the scene of sharing requirements of high-power SOC and peripheral equipment by using hardware isolation, and is particularly applicable to the field of intelligent cabins. There may be multiple cores in the SOC.
Specifically, as shown in fig. 2 and 3, the SOC is isolated into a first system 102 (meter system) and a second system 104 by means of hardware isolation, and the second system 104 may be a Hypervisor host system. The second system 104 may have two subsystems running therein, such as two hypervisors subsystems 103.

The virtualization type of the instrumentation system may be type3. The virtualization type of the Hypervisor host system may be type1. In fig. 2, an arrow (1) represents an audio data stream (audio data stream) of type3, an arrow (2) represents an audio data stream (audio data stream) of type1, an arrow (3) represents an image data stream (graphics data flow), and an arrow (4) represents a physical data stream (physical data flow). When the vehicle-mounted cabin is started, domain image files of the Hypervisor main system and the instrument system can be loaded, and the Hypervisor main system and the instrument system are started.
Taking the audio-video virtualization example of the hybrid virtualization model 100, the audio-video virtualization process may include:
step S21: and initializing the type3 kernel mode back-end program and the type1 user mode back-end program of the Hypervisor main system. After the initialization is finished, the central control system can be started, and an AudioFinger service, a surface eFinger service and a weston service on the central control system are operated to display the picture of the central control system on a central control screen. The gaming system and Xorg service may also be started, displaying the game screen with a picture of the gaming system.
Step S22: the hardware isolated instrumentation system initializes the type3 front-end audio driver, creating a virtual sound card device for the instrumentation system. After creating the virtual sound card device of the instrumentation system, the weston service of the instrumentation system may be started, and the screen of the instrumentation system may be displayed on the corresponding instrumentation screen or the lift-off screen.
Step S23: the Pulse Audio service in the instrument system is started, and the Pulse Audio service writes the Audio data of the instrument system into a virtual sound card created by the type3 front-end driver. The Pulse Audio service is mainly responsible for the Audio mixing function inside the meter system.
Step S24: the audio backend program (qemu) of the Hypervisor host system parses the audio data of the central control system or game system.
Step S25: the audio backend program (qemu) of the Hypervisor host system writes the audio data of the central control system or the game system into the physical Sound card device (Sound driver).
Step S26: the type3 audio backend program of the Hypervisor host system parses the audio data of the instrumentation system.
Step S27: the physical sound card of the Hypervisor main system drives and processes the audio data received by the rear end of the type1 and the rear end of the type3, and the cross-system sound mixing function of the mixed virtualization model 100 is realized.
The steps ensure the safety of the instrument system and the sharing performance advantage of the Hypervisor main system while realizing the cross-system audio mixing function of the hybrid virtual model 100, and have remarkable progress.
