Device and method for program correction by kernel-level hardware monitoring and correlating hardware trouble to a user program correction

An information processing device which realizes desired functions using a hierarchical structure, the device comprising:

• a group of hardware of various types disposed in a first layer which is the lowest layer of the hierarchical structure;
• a kernel, a kernel module and a hang checking part disposed in a second layer which is the hierarchical layer above said first layer;
• and
• a group of user programs of various types and a monitoring program for monitoring and grasping operating states of the user programs disposed in a third layer which is the hierarchical layer above said second layer;
• wherein the kernel module is used to access hardware corresponding thereto in response to a request from said user program;
• wherein the hang checking part performs hang checking by inspecting whether the hardware access performed by said kernel module corresponding thereto is in a normal state or in an abnormal state, and outputting a hardware trouble detection notification in a case where an abnormality in the hardware access is detected;
• and
• wherein said monitoring program performs checking the operating states of the user programs corresponding to said hardware trouble detection notification in response to said hardware trouble detection notification, and executes a specified operation against hardware trouble when said operating states become such that the execution of said specified operation against hardware trouble is permissible.
