AI Technical Summary
Technical Problem
Existing page fault handling methods cannot effectively identify and accurately locate the specific process causing the page fault, resulting in user processes being unable to perceive and handle the exception.
Method used
By introducing a shared memory region and a range tree structure into the graphics processing system, data exchange is carried out between the kernel-mode driver module and the user-mode driver module. The range tree structure is used for fast querying to determine the resource range node of the page fault and to perform corresponding processing.
Benefits of technology
It enables accurate location and handling of page faults, improves the efficiency and accuracy of fault handling, and ensures the stability and performance of the system.

Abstract
The application relates to a page fault exception problem processing method and device, computer equipment, a computer readable storage medium and a computer program product. The method is applied to a user state driving module of a graphics processing system, the graphics processing system comprises a kernel state driving module and the user state driving module; the method comprises the following steps: in response to a page fault exception event trigger instruction, obtaining a processor virtual address of a page fault exception from a shared memory area; wherein the shared memory area refers to a shared storage area of the kernel state driving module and the user state driving module; according to the processor virtual address, performing a query in an interval tree structure to obtain a resource interval node corresponding to the processor virtual address; wherein the interval tree structure is used for storing allocation information of the resource interval node by taking a start address of a processor virtual address interval as a key value; and performing page fault exception processing according to the resource interval node. The method can accurately locate and process the page fault exception problem.
