Embodiment Construction
[0037] The implementation steps of the kernel code soft fault-tolerant method for hardware non-recoverable memory failure in the embodiment of the present invention are as follows:
[0038] 1) When the operating system loads the kernel code into the physical memory, mark the kernel code as the main code, set multiple code copies for each kernel code and load the code copy into the physical memory;
[0039] 2) When the operating system is running, if the memory where the kernel code is located encounters a memory exception, locate the error kernel page of the current main code, compare the code of the error kernel page with the code copy corresponding to the current main code, and if it is determined to be the error kernel If an error occurs in the code of the page, the operation of the computer is suspended, the kernel code page table of the wrong kernel page is modified, a normal code copy is selected from the code copies corresponding to the current main code to replace the c...
