Abstract

PROBLEM TO BE SOLVED: To automatically evade the conflict between the system resources and the peripheral device resources of an existing environment and an emulator environment and setting a user free from setting a peripheral device in an H/W emulator environment. SOLUTION: A device recognition part 1 recognizes whether the resource information requests of a device driver 10 and an emulator device 12 are given to an emulator environment or an existing environment. A device management part 2 manages a peripheral device 9 and an emulator peripheral device 11 based on the recognized resource information. A resource management part 3 and an emulator resource management part 5 manage the resources. Then a resource setting part 4 and an emulator resource setting part 6 set the resource information to the equipment 9 and 11 respectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resource management device for a peripheral device, and more particularly to a resource management device for a peripheral device in a computer system using peripheral devices having different H / W control interfaces.

[0002]

2. Description of the Related Art Conventionally, in an H / W emulator environment of a computer system that uses peripheral devices having different H / W control interfaces, the same interface is used for each device driver, so that resource information of peripheral devices is There will be conflicting problems. For this reason,
It is necessary to individually manage the resources, and the setting is made by the user by referring to the resources already used.

[0003]

However, in such a conventional resource management method for a peripheral device, the user has to perform resource management for each environment, and if there is no knowledge of the user, resource competition occurs. There are cases where it cannot be avoided and peripheral devices cannot be used. In addition, since resource management by software cannot be performed in the emulation environment, there is a problem that the user must set the resources of the peripheral device using a switch or the like.

[0004]

The device of the present invention is an H / W
In a resource management device for a peripheral device in a computer system using a peripheral device with a different control interface, it is automatically determined whether the resource of the peripheral device used is for the H / W emulator environment or the existing environment. Device recognizing unit, which manages the peripheral device for each environment based on the recognized resource information, a resource managing unit which manages the resource of the peripheral device corresponding to the environment, and an emulator resource management. Section, and a resource setting section and an emulator resource setting section for setting the resource information of the resource managing section and the emulator resource managing section to the peripheral device and the emulator peripheral apparatus, respectively, and the existing environment and the emulator environment are maintained even under the H / W emulator environment. Peripheral resources and system resources Resource management device over scan is characterized by automatically avoid the conflict.

[0005]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The HW lease management unit 100 includes a device recognition unit 1, a device management unit 2, a resource management unit 3, a resource setting unit 4, and an emulator resource. It is composed of a management unit 5 and an emulator resource setting unit 6. Further, the management unit 2 has a non-volatile memory 7, and the device recognition unit 1 has a device driver 10 and an emulator device driver 1.
2. A peripheral device 9 is connected to the resource certifying unit 4, and an emulator peripheral device 11 is connected to the emulator resource setting unit 6.

Initially, the non-volatile memory 7 is written with resource information of peripheral devices (memory space address, I / O space address, interrupt signal, etc.) corresponding to the minimum necessary computer system configuration. . Also,
The peripheral device setting information file 8 stores, for each peripheral device, resource candidates that can be used by the peripheral device.

Next, the operation of this embodiment will be set with reference to the drawings.

When the computer system is started up, the device management unit 2 acquires the resource information of the peripheral device in the non-volatile memory 7, and the resource information is for the time of functioning as an H / W emulator, or of the existing environment. It is determined whether or not it is for the functioning below, and the resource information of each peripheral device is notified to the resource management unit 3 or the emulator resource management unit 5 and registered. The resource information is grasped by the device management unit 2 as connection information of the peripheral device (information indicating whether or not the peripheral device is connected to the computer system).

Further, the device recognition unit 1 searches for a peripheral device newly added corresponding to the computer system in which the resource information of the peripheral device does not exist in the non-volatile memory 7 by input / output access. When the newly added peripheral device is confirmed, the device recognition unit 1 acquires a resource candidate usable by the peripheral device from the peripheral device setting information file 8. The device management unit 2 recognizes the environment to be used depending on the difference in peripheral device resources, and by referring to the resource management unit 3 or the emulator resource management unit 5, it is checked whether or not the resource information is already registered, and the resource setting is performed. Check if it is possible. If the setting is possible, the settable resource information is registered in the device management unit 2.

If the peripheral device needs to be reset when the processing by the computer system is completed and then restarted, the device management unit 2 sets the peripheral device under the environment of the target peripheral device. It notifies / registers the resetting candidates of all certain peripheral devices to the resource managing unit 3 or the emulator resource managing unit 5. When the resource information corresponding to all peripheral devices can be set, the resource information is registered in the device management unit 2, the resource management unit 3, or the emulator resource management unit 5. The resource information of the peripheral device that cannot be set is deleted from the device management unit 2.

After that, the resource setting unit 4 and the emulator resource setting unit 6 set the resource information of the peripheral device 9 and the emulator peripheral device 11, respectively, based on the data set by the device management unit 2. When all the settings are completed, the information of the device management unit 2 is stored in the nonvolatile memory 7
Is evacuated to. As a result, all the peripheral devices 9 and the emulator peripheral device 11 are automatically set.

During operation of the computer system in which the operating environment is prepared as described above, the device driver 10 and the emulator device driver 12 acquire the resource information of the peripheral device 9 and the emulator peripheral device 11 which are controlled by themselves. / W Access the resource management unit 100. At this time, the device recognition unit 1 determines whether this request is a request from the conventional environment or a request from the emulator environment, and the device management unit 2 searches whether or not a peripheral device for the request exists. If the peripheral device exists, the resource information set in the peripheral device is provided. This allows resource management in the emulator environment to be performed by software.

[0014]

As described above, the present invention automatically recognizes whether the requested resource is used in the H / W emulator environment or the existing environment, and the peripheral device unit By managing each resource collectively with, resource conflicts can be avoided and software can automatically perform resource management in the H / W emulator environment, which was previously done by the user. Has the effect of being reduced.
