In the embodiment of the invention, physical resource use information used for indicating physical resources required by application running is obtained; optionally, the physical resource usage information includes at least one of: physical memory information, Central Processing Unit (CPU) information, register access control authority, read-write authority of input/output equipment and privilege instruction execution authority; optionally, the physical resource usage information may further include other physical resource information, which is not limited in the present invention.
Optionally, step S101 includes: acquiring preset physical resource use information; or, obtaining the physical resource use information according to a hardware control data structure sent by the application; wherein the hardware control data structure includes the physical resource usage information.
In this embodiment of the present invention, the physical resource usage information may be preset physical resource usage information, or may be obtained according to a hardware control data structure including the physical resource usage information and sent by the application.
S102, according to the physical resource use information, independent physical resources are distributed for the application, and an interface for directly accessing the physical resources is distributed for the application, so that the application directly accesses the physical resources.
In the embodiment of the present invention, after physical resource usage information indicating a physical resource required for an application to run is acquired, an independent physical resource (i.e., a physical resource that is not usable by other applications) (e.g., a CPU, a physical memory, an I/O device, and a privilege instruction execution authority) is allocated to the application according to the physical resource usage information, and an interface for directly accessing the physical resource is allocated to the application, so that the application directly accesses the physical resource through the interface, that is, the application is upgraded to an authorization application that can directly access the physical resource (e.g., directly execute a privilege instruction, directly manage a CPU, directly manage a physical memory, and directly access an I/O device, etc.) by bypassing an operating system kernel; therefore, resource contention of different applications to the kernel of the operating system is reduced, and system performance is improved.
Optionally, allocating an interface for the application to directly access the physical resource includes: and establishing a user space system service function library for the application, and copying a management data structure of a kernel required by the application into the user space system service function library, wherein the management data structure is used for directly accessing the physical resources.
In order to ensure nutritional compatibility, an interface for directly accessing the physical resources is provided for the application in a mode of establishing a user space system service function library for the application and copying a management data structure of a kernel required by the application into the user space system service function library; optionally, processor virtualization hardware is initialized according to the physical resource, and the user space system service function library initializes the independent physical resource, so as to provide an interface for the application through the user space system service function library (optionally, the user space system service function library includes a service management function routine corresponding to the independent physical resource, and the application directly calls the service management function routine in the user space system service function library to access or manage the physical resource without trapping in an operating system kernel during execution); namely, the application after the privilege escalation can maintain the normal operation of the application directly through the operation of managing and updating the management data structure in the user space system service function library.
Optionally, the resource management method of the present invention further includes: allocating a management policy for managing the physical resources to the application; wherein the user space system service function library comprises: the management policy; so that the application can directly access or manage the physical resources through the interface and/or management policy in the user space system service function library.
In the embodiment of the present invention, the operating system may be an open-source Linux operating system, an operating system such as a Windows operating system developed by Microsoft corporation, an Android system developed by Google corporation, or an iOS system developed by Apple corporation, or an embedded operating system such as Vxworks. The operating system includes various components and/or drivers for controlling and managing conventional system tasks, such as memory management, storage device control, power management, etc., as well as facilitating communication between various hardware and software components.
In the embodiment of the invention, physical resource use information is acquired and used for indicating physical resources required by application operation; further, according to the physical resource use information, allocating an independent physical resource for the application, and allocating an interface for directly accessing the physical resource for the application, so that the application directly accesses the physical resource; namely, the application can bypass the kernel of the operating system to directly access the physical resource, so that the resource contention of different applications to the kernel of the operating system is reduced, and the system performance is improved.
When the I/O device is a shared device, in order to ensure the security of the application accessing the I/O device, optionally, the I/O device is shared with other applications through a messaging system call, for example, a message requesting the I/O device is sent to an operating system kernel through an interface provided by a user space system service function library corresponding to the application.
Optionally, after step S102, the method further includes: and dynamically updating the independent physical resources and synchronously updating the kernel management data structures in the kernel of the operating system and the kernel management data structures in the user space system service function library.
In this embodiment of the present invention, optionally, when the privilege-granting application needs to change a physical resource (for example, change a control privilege or apply for a physical memory, a CPU, an I/O device, or the like) in an operation process, the privilege-granting application may send a request message (the request message includes physical resource information that the privilege-granting application needs to update) to the resource management device in the kernel of the operating system by calling an interface that is included in the user space system service function library and used for interacting with the kernel of the operating system, so that the resource management device dynamically updates the independent physical resource according to the request message; optionally, the management data structures in the user space system service function library (i.e. the user mode specified memory) and the operating system kernel are updated according to the physical resource information to be updated.
Optionally, when the privilege offering application needs to change physical resources (for example, release a physical memory, a CPU, an I/O device, and the like) during the running process, the privilege offering application may dynamically update the independent physical resources directly through the user space system service function library, and further, may update a management data structure in the user space system service function library (that is, a user-mode specified memory) through the user space system service function library, and send modification information to the resource management device in the operating system kernel, so that the resource management device synchronously updates the kernel management data structure in the operating system kernel.
Optionally, dynamically updating the independent physical resource further includes the following three scenarios:
scenario 1: when the application (i.e. the right-lifting application) accesses the resource management device each time, the resource management device determines whether to update the independent physical resource allocated to the application according to a preset resource allocation policy and a calling parameter (optionally, the calling parameter may include parameters such as a resource type and a resource size of the independent physical resource);
scenario 2: when the application (namely the right-lifting application) falls into an operating system kernel state due to triggering exception, the operating system kernel judges whether the independent physical resource distributed to the application needs to be updated or not;
scenario 3: periodically judging whether the independent physical resources distributed to the application need to be updated by the operating system kernel; if the hardware supports, directly modifying task authority, directly updating and setting a CPU and a register, and dynamically adjusting the execution authority of the CPU and the register, for example, changing partial access management authority of the CPU to the CPU hardware by setting a data structure provided by a Virtual machine control block (VMCS for short); if the hardware does not support, triggering an interrupt to make the application (the privilege application) enter a kernel state, and updating the independent physical resource allocated to the application.
Optionally, after step S102, the method further includes: and setting an exception handling function, wherein the exception handling function is used for carrying out exception handling by the application according to the exception handling function when the application triggers exception.
In the embodiment of the present invention, an exception handling function is set, so that when the application (i.e., the authorization application) triggers an exception, the application performs exception handling according to the exception handling function. Optionally, exception handling processes fall into two categories: the first type is that the user space system service function library contains a customized exception handling function, and the second type is a handling process needing to pass through an operating system kernel; when zero-removing exception, page missing exception or invalid operation code (invalid opcode) or the like occurs in the application, the application performs exception handling through an exception handling function in the user space system service function library; when the application violates the physical resource authority range information corresponding to the application in the execution process, if a register without read-write authority is read and written, and hardware triggers exception or state switching, the application saves the current execution environment, loads the execution environment of an operating system kernel, and performs exception handling according to the exception handling function; alternatively, when the exception handling is completed, the resource management apparatus restores the application to the privileged application again (i.e., re-executes the processes of step S101 and step S102), so that the privileged application continues to execute normally.
Referring to fig. 1A, a second embodiment of the resource management method of the present invention may include the following steps:
1) an application sends physical resource use information used for indicating physical resources required by the running of the application to the resource management device through an interface provided by an operating system kernel, and optionally sends the physical resource use information to the resource management device in a form of a hardware control data structure; optionally, the physical resource usage information includes at least one of: physical memory information, Central Processing Unit (CPU) information, register access control authority, read-write authority of input/output equipment, privilege instruction execution authority and interrupt direction.
2) The resource management device of the operating system kernel allocates an independent physical resource to the application according to the physical resource usage information sent by the application, and allocates an interface for directly accessing the physical resource to the application, such as initializing a physical memory of the application, storing and initializing a register on a CPU required by the application, and constructing a new interrupt vector table and other data structures; optionally, processor virtualization hardware is initialized according to the physical resources allocated to the application, and the physical resources are initialized by a user space system service function library, so as to provide an interface for directly accessing the physical resources to the application through the user space system service function library.
3) The resource management device saves the current execution environment of the application, such as register values, register states, segment registers and the like; loading an execution context corresponding to the privileged application after the application upgrade (i.e. independent physical resources allocated to the application, such as physical memory information, Central Processing Unit (CPU) information, CPU register setting and the like), so that the privileged application directly accesses or manages the physical resources according to the user space system service function library; wherein the userspace system services function library is to provide the privileged application with an administration policy to administer the physical resource and an interface to directly access the physical resource.
4) The resource management device sets an execution entry point and an exception handling function; when the privilege-giving application triggers an exception in the execution process, the context (such as CPU register information and the like) is saved, the next process is switched to, and exception handling is carried out according to the exception handling function.
In summary, in this embodiment, an independent physical resource is allocated to the application, and an interface for directly accessing the physical resource is allocated to the application, so that the application directly manages or accesses the physical resource according to the user space system service function library, and the physical resource does not need to be managed by the operating system kernel, thereby reducing resource contention of different applications on the operating system kernel, and improving system performance.
FIG. 2A is a diagram of a second operating system architecture of the resource management method of the present invention. As shown in fig. 2A, the management core (core) is used to set an instruction execution authority, a register read-write authority, an I/O device, and the like of the application core (core); the method comprises the following steps that an authorization application directly accesses or manages independent physical resources corresponding to the authorization application through a customized user space system service function library (LibXOS); the resource management device is used for process privilege escalation (namely upgrading a common application into a privilege escalation application, specifically, setting a resource privilege range of a process executed on an application core through a management core), wherein the common application needs to access or operate physical resources through an operating system kernel each time, and the privilege escalation application can directly access or operate the corresponding physical resources according to a corresponding user space system service function library); the resource management device is also used for exception handling when the privilege-lifting application exceeds the execution privilege; the user space system service function library acquires remote I/O service through message system call; in addition, when the privilege-granting application cannot realize a certain kernel function through the user space system service function library, the privilege-granting application can write to a specified memory through the request queue, and the service thread reads a response.
Fig. 2B is a schematic diagram of a third embodiment of the resource management method of the present invention, and as shown in fig. 2B, a method for performing page table management in a user mode space is specifically described. Optionally, when the authority of the general application is lifted, the page table data structure in the kernel of the operating system of the general application is copied to a specified physical memory, and is managed by a page table management module in the user mode space system service function library, including operations such as reading, writing and/or updating the page table. When the application is trapped from a non-root mode to a root mode, i.e. to the operating system kernel for reasons such as active or passive (e.g. exception), it is necessary to synchronize the page table data structure to the page table structure managed by the original kernel. Because the virtual memory and the physical memory are discretely mapped in the page table, when the page table data structure is copied, the physical memory mapped in the kernel page table needs to be locked in the kernel and cannot be swapped out; and for the items not filled in the page table, the user mode system service function library manages according to the information of the application request, the execution process state, the reserved physical memory and the like.
Fig. 2C is a schematic diagram of a fourth embodiment of the resource management method of the present invention. As shown in fig. 2C, the content of the memory managed, applied, allocated and released by the user space system service function library (LibXOS) is specifically described. The memory management in LibXOS mainly provides two functions, wherein 1) the first function is: for the function routines of applying and releasing the memory required by the application, the LibXOS only manages the physical memory allocated by the resource management device when the application is authorized, so that all the applying and releasing operations only aim at the reserved physical memory; when the physical memory is exhausted, a new physical memory needs to be applied to the kernel of the operating system in an active and operating system kernel interaction mode to increase the physical memory reserved for the application, the process of applying for the new physical memory is an active trapping operating system mode, namely, the new physical memory is trapped into the kernel of the operating system through vmcall, then the new physical memory is responded by an exception handling function in the kernel of the operating system according to the transmitted parameters, the physical memory is distributed, and finally the process returns; 2) the second part of functions are as follows: processing a user mode page missing exception, wherein the page missing exception refers to a hardware exception triggered by accessing the virtual address when a mapping item in a page table does not exist; the existing Linux and most other operating systems are completed through an exception handling function of a kernel, but in the embodiment of the invention, when the authority of common application is lifted, the existing hardware exception handling function is updated and initialized, and a VMCS data structure is set, so that when the page fault exception occurs, the hardware throws the page fault exception to a user state and the user state page fault exception handling function in a user space system service function library is used for handling the page fault exception, specifically, the user state page fault exception handling function can be written in a page turning mode according to needs in the existing operating system, or the user state page fault exception handling function can be written in a page turning mode in advance, and therefore, the system performance of the application with different memory use requirements is improved.
