Scenario 2: When the application (that is, the privilege escalation application) falls into the operating system kernel state due to a trigger exception, the operating system kernel determines whether the independent physical resources allocated for the application need to be updated;

Scenario 3: The operating system kernel periodically determines whether the independent physical resources allocated for the application need to be updated; if the hardware supports it, it directly modifies the task permissions, directly updates and sets the CPU and registers, and dynamically adjusts its execution permissions. Set the data structure provided by the virtual machine control block (Virtual machine control block, VMCS for short) to change some of its access management rights to the CPU hardware; if the hardware does not support it, trigger an interrupt to make the application (privilege escalation application) fall into the kernel state , and update the individual physical resources allocated for the application.

To sum up, in this embodiment, by allocating independent physical resources to the application and assigning the application an interface for directly accessing the physical resource, the application can serve the function library according to the user space system The physical resources are directly managed or accessed without managing the physical resources through the operating system kernel, thereby reducing resource contention of the operating system kernel by different applications and improving system performance.

FIG. 2A is a second operating system architecture diagram of the resource management method of the present invention. As shown in Figure 2A, the management core (core) is used to set the instruction execution authority, register read and write authority, and I/O devices of the application core (core); the privilege escalation application uses the customized user space system service function library (LibXOS) Directly access or manage the independent physical resources corresponding to the privilege escalation application; the resource management device is used for process privilege escalation (that is, to upgrade a common application to a privilege escalation application, specifically, setting the process execution value on the application core through the management core). Scope of resource authority; in which, ordinary applications need to access or operate physical resources through the operating system kernel each time, and privilege-escalation applications can directly access or operate their corresponding physical resources according to their corresponding user space system service function libraries); The resource management device is also used to handle exceptions when the privilege escalation application exceeds the execution authority; the user space system service function library obtains remote I/O services through message-based system calls; in addition, when the privilege escalation application cannot pass When a certain kernel function is implemented by the user space system service function library, it can be written to the specified memory through the request queue, and the response is read by the service thread.

Management, including operations such as reading, writing and/or updating page tables. When the application falls into root mode from non-root mode, that is, falls into the operating system kernel due to active or passive (such as exception) reasons, the page table data structure needs to be synchronized to the original Kernel-managed page table structure. Since the virtual memory and physical memory are discretely mapped in the page table, when copying the page table data structure, the physical memory that has been mapped in the kernel page table needs to be locked in the kernel and not allowed to be swapped out. ; For items that have not yet been filled in the page table, they are managed by the user-mode system service function library according to information such as application requests, execution process status, and reserved physical memory.

As shown in FIG. 2C , the content of managing, applying, allocating and releasing memory through the user space system service function library (LibXOS) is described in detail. The memory management in LibXOS mainly provides two parts of functions, among which, 1) the first part of the function is: for the function routines required by the application to apply and release the memory, LibXOS only manages the physical memory allocated by the resource management device when the application is elevated. Therefore, all application and release operations are only for the reserved physical memory; but when the physical memory is exhausted, it is necessary to apply for new physical memory to the operating system kernel by actively interacting with the operating system kernel to increase the For the physical memory reserved for the application, the process of applying for a new physical memory is to actively fall into the operating system mode, that is, fall into the operating system kernel through vmcall, and then respond by the exception handling function in the operating system kernel according to the passed parameters , and allocate physical memory, and finally return; 2) The second part of the function is: user mode page fault exception handling, where page fault exception refers to the hardware exception triggered by accessing the virtual address when the mapping entry in the page table does not exist Existing Linux and most of other operating systems are completed by the exception handling function of the kernel, but in the embodiment of the present invention, the existing hardware exception handling function is updated and initialized when the common application is elevated, and the VMCS data structure is set, When a page fault exception occurs, the hardware will throw the page fault exception to the user mode, and it will be processed by the user mode page fault exception handling function in the user space system service function library. The user-mode page fault exception handling function can be written by paging, or the user-mode page fault exception processing function can be written by paging in advance. Therefore, the system performance of applications with different memory usage requirements is improved.
