Embodiment Construction

[0029] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0030] As mentioned above, the establishment and use of the current multi-domain communication channel is limited to between multi-domain operating systems, and the multi-domain communication channel between the OBP and the multi-domain operating system has not yet been realized. Therefore, OBP cannot use various services provided by the operating system. According to the OBP-based BIOS communication method with the multi-domain operating s...

Abstract

The invention discloses a method for communicating between an OBP-based BIOS and a multi-domain operating system, which is used for communication between the OBP supporting multi-domain startup and the BIOS in an operating system supporting multi-domain communication and the multi-domain operating system. The method includes: after the multi-domain hardware platform system is powered on, the middle software layer is run to allocate hardware resources; the main domain OBP completes the hardware initialization of the main domain operating system, starts the multi-domain communication channel driver, and establishes the multi-domain communication channel under the main domain; The domain OBP completes the hardware initialization of the slave domain operating system, establishes a multi-domain communication channel under the slave domain, and sends a communication request to the master domain operating system; the master domain operating system responds to the communication request sent by the slave domain operating system; the slave domain OBP Establish communication with the primary domain operating system through the multi-domain communication channel, invoke services provided by the primary domain operating system, and complete customized functions. The invention realizes the communication with the main domain operating system, and can call the service provided by the main domain operating system.

Description

technical field [0001] The invention relates to the technical field of cloud computers, in particular to a method for communicating between an OBP-based BIOS and a multi-domain operating system. Background technique [0002] OBP (Open Boot PROM) is an implementation method of computer BIOS. It was first applied to the servers of SUN Microsystems in the United States, and then widely used on SPARC architecture processor computer platforms. OBP initializes and configures hardware, loads drivers for third-party boards, controls the computer's boot process, and provides diagnostic tools under the command line. OBP is implemented by FORTH language, which can support users to manage computer systems, such as interactive diagnosis work, etc.; it can be used to interpret and execute or incrementally compile device drivers written in FCODE stored in the EEPROM of the external device to realize the "peripheral" Plug and Play". [0003] A multi-domain operating system refers to two o...
