Abstract

The method for controlling a computer that notifies an operating system of a request event corresponding to a device event from hardware. A device event may be generated, for example by a user operating a keyboard or mouse connected to the computer. That is, the device event occurs when a certain event is provided to the hardware of the computer. A request event causes a process corresponding to the device event to be performed under the control of an operating system. Then a response event from the operating system caused by the notification of the request event is accepted and a process event corresponding to the accepted response event is output to the hardware.

Claims

1. A method for controlling a computer for a device event provided from hardware, in which said computer comprises a basic system for notifying an operating system of a request event corresponding to the device event in response to the device event from said hardware, accepting a response event of the operating system caused by the notification, and outputting a process event corresponding to the accepted response event to the hardware, comprising the steps of:

notifying said operating system of an additional event associated with the response event after receiving said response event in said basic system;

accepting an additional response event corresponding to said additional event from said operating system; and

,

outputting an additional process event corresponding to said accepted additional response event to said hardware.

2. The method for controlling a computer according to

claim 1

, further comprising the steps of:

performing the notification of an intermediate event after accepting said response event and outputting said process event in said basic system;

accepting said intermediate event; and

notifying said operating system of an additional event associated with said response event.

3. The method for controlling a computer according to

claim 2

, wherein said basic system conforms to an ACPI standard.

4. The method for controlling a computer according to

claim 3

, wherein said device event is an attach/detach event which is generated when the attachment/detachment of a peripheral device is indicated to said hardware during energy-saving mode of said computer, said process event is an event for switching said computer from said energy-saving mode to normal mode and allowing said peripheral device to be attached/detached, and

said additional process event is an event for switching said computer from said normal mode to the energy-saving mode after said process event is output.

5. The method for controlling a computer according to

claim 3

, wherein said basic system comprises the steps of:

notifying said operating system of a second request event associated with said request event as well as said request event;

accepting said second request event and monitoring said process event;

notifying said operating system of an intermediate event after accepting said response event and outputting said process event;

accepting said intermediate event; and

notifying said operating system of an additional event associated with said response event.

6. The method for controlling a computer according to

claim 4

, wherein said basic system comprises the steps of:

notifying said operating system of a second request event associated with said request event as well as said request event;

accepting said second request event and monitoring said process event;

notifying said operating system of an intermediate event after accepting said response event and outputting said process event;

accepting said intermediate event; and

notifying said operating system of an additional event associated with said response event.

8. The computer according to

claim 6

, wherein said basic system further comprises:

a second notifier for performing the notification of an intermediate event after accepting said response event and outputting said process event; and

a second acceptor for accepting said intermediate event.

10. The computer according to

claim 8

, wherein said device event is an attach/detach event which is generated when the attachment/detachment of a peripheral device is indicated to said hardware during energy-saving mode of said computer, said process event is an event for switching said computer from said energy-saving mode to normal mode and allowing said peripheral device to be attached/detached, and said additional process event is an event for switching said computer from said normal mode to the energy-saving mode after said process event is output.

11. The computer according to

claim 8

, wherein said basic system further comprises:

a third notifier for notifying said operating system of a second request event associated with said request event as well as said request event; and

a monitor for accepting said second request event and monitoring said process event.

14. The recording medium according to

claim 11

, wherein there is recorded the program further comprising the steps of:

performing the notification of an intermediate event after accepting said response event and outputting said process event in said basic system;

accepting said intermediate event; and

,

notifying said operating system of an additional event associated with said response event.

16. The recording medium according to

claim 14

, wherein said device event is an attach/detach event which is generated when the attachment/detachment of a peripheral device is indicated to said hardware during energy-saving mode of said computer, said process event is an event for switching said computer from said energy-saving mode to normal mode and allowing said peripheral device to be attached/detached, and said additional process event is an event for switching said computer from said normal mode to the energy-saving mode after said process event is output.

17. The recording medium according to

claim 14

, wherein there is recorded the program causing said basic system to further perform the steps of:

notifying said operating system of a second request event associated with said request event as well as said request event;

accepting said second request event and monitoring said process event;

notifying said operating system of an intermediate event after accepting said response event and outputting said process event;

accepting said intermediate event; and

notifying said operating system of an additional event associated with said response event.

7. A computer comprising a basic system for notifying an operating system of a request event corresponding to a device event in response to the device event from hardware, accepting a response event of the operating system caused by the notification, and outputting a process event corresponding to the accepted response event to said hardware, wherein said basic system comprises:

a notifier for notifying said operating system of an additional event associated with said response event after receiving said response event;

an acceptor for accepting an additional response event corresponding to said additional event from said operating system; and

an output for outputting an additional process event corresponding to said accepted additional response event to said hardware.

9. The computer according to

claim 7

, wherein said basic system conforms to an ACPI standard.

12. The computer according to

claim 9

, wherein said basic system further comprises:

a third notifier for notifying said operating system of a second request event associated with said request event as well as said request event; and

a monitor for accepting said second request event and monitoring said process event.

13. A recording medium containing a program for controlling a computer for a device event provided from hardware, said computer comprising a basic system for notifying an operating system of a request event corresponding to the device event in response to the device event from the hardware, accepting a response event of the operating system caused by the notification, and outputting a process event corresponding to the accepted response event to said hardware, wherein there is recorded the program comprising the steps of:

notifying said operating system of an additional event associated with said response event after receiving said response event in said basic system;

accepting an additional response event corresponding to said additional event from said operating system; and

outputting an additional process event corresponding to said accepted additional response event to said hardware.

15. The recording medium according to

claim 13

, wherein said basic system conforms to an ACPI standard.
