Fig. 1 is the process flow diagram of the method for the key invokes application among the embodiment.
[embodiment]
Fig. 1 shows the method flow of the key invokes application among the embodiment, and this method flow may further comprise the steps:
Among the step S100, button is pressed, and the control of generation system is interrupted.
(System Control Interrupt is interrupted in system's control; Be called for short " SCI ") be a kind of advanced configuration and power-management interface (Advanced Configuration and Power Interface of stemming from; Abbreviation " ACPI ") system break of compatible chip; The ACPI event interrupt vector that system map is different is so that share this interruption, when the control of bottom hardware generation system is interrupted, according to notice OSPM (OS-directed PowerManagement; The management of operating system direct energy source) layer is handled corresponding ACPI incident, and the OSPM layer can call preassembled interrupt handler.
Among the step S200, responding system control is interrupted, output and said button corresponding identifier.The different identifier of the corresponding output of different keys can be set.
Among the step S300, call corresponding application program according to said identifier.The application program that can call comprises but is not limited to virus scan antivirus applet, system reducing program, system backup program, system upgrade program, application software upgrade program and data sync program etc.
Stipulated in some chipset the general input and output of part (General Purpose Input Output, GPIO) pin can be realized multiple function according to different configurations, these GPIO pins belong to function reusable interface.For example: Intel5 family chip group and Intel3400 family chip group.In the embodiment of the invention, adopt the GPIO0～GPIO15 in the general input and output pin, these pins all can be configured to the GPIO pin that responding system control is interrupted.
In the foregoing description, before execution in step S100, need carry out hardware and connect and register configuration.Wherein, it is that button is connected with general input and output pin GPIO0～GPIO15 that hardware connects, and can connect 16 buttons at most.
In order the general input and output pin GPIO0～GPIO15 that is connected with button to be produced and correct responding system control interruption under operating system, need the configuration relevant register, wherein the register of required configuration is following:
Configuration advanced configuration and power-management interface control register ACPI_CNTL (ACPI ControlRegister) enable the ACPI pattern.Because system's control interruption needs the support of operating system, only under the ACPI pattern, just can use, and therefore need enable the ACPI pattern.The bit of ACPI_CNTL [7] position can enables/disables ACPI pattern, and the bit of ACPI_CNTL [7] position is set to " 1 ", then enables the ACPI pattern.
Configuration register ACPI_CNTL, the interruption route mapping that enabled systems control is interrupted.The bit of register ACPI_CNTL [2:0] position can be used to be provided with the interruption route mapping that system's control is interrupted; System's control is interrupted can being mapped as IRQ9, IRQ10, IRQ11, IRQ12, IRQ22 or IRQ23 according to the configuration of bit [2:0] position, and IRQ is an interrupt request.If bit [2:0] is configured to 000b, then system's control interrupt map is IRQ9, if bit [2:0] is configured to 010b, then system's control interrupt map is IRQ11, and the like.In the embodiment of the invention, acquiescence is interrupted in system's control be mapped as IRQ9.
Configuration power management control register, enabled systems control is interrupted.General input and output pin GPIO0～GPIO15 can be correctly under operating system responding system control interrupt, also need enabled systems control to interrupt.The bit [0] that will dispose power management control register PM1_CNT (Power Management 1 Control) is set to " 1 ", and then enabled systems control is interrupted.
Configure generic input and output control register, enable pass is used input/output function.Can responding system general input and output pin GPIO0～GPIO15 of interrupting of control must be configured to the GPIO function; The bit [4] of general input and output control register GC (GPIO Control Register) position is used for enables/disables GPIO function, bit [4] position of GC is configured to " 1 " enables the GPIO function.
Configure generic input and output route control register, enable pass is interrupted with the control of input and output pin route generation system.In order under operating system, to control interruption by correct responding system, general input and output pin GPIO0～GPIO15 need be configured to and can the control of route generation system interrupt.Configuration to the bit [31:0] of general input and output route control register GPIO_ROUT (GPIO Routing Control Register) can realize general input and output pin GPIO0～GPIO15 route control that control is interrupted to system.Wherein, Bit [1:0] is configured to the route setting that 10b realizes that promptly control is interrupted to general input and output pin GPIO0 system; Bit [3:2] is configured to the route setting that 10b realizes that promptly control is interrupted to general input and output pin GPIO1 system; Bit [5:4] is configured to the route setting that 10b realizes that promptly control is interrupted to general input and output pin GPIO2 system, and the like.
Configure generic input and output pin uses mask register, selects the mode of operation of general input and output pin is arranged to general input and output mode.Be used for the signal that transmission system control interrupts through input and output pin GPIO0～GPIO15, therefore need be arranged to the GPIO pattern to the mode of operation of general input and output pin GPIO0～GPIO15.Use the bit [15:0] of mask register GPIO_USE_SEL (GPIOUse Select Register) to enable accordingly to be provided with general input and output pin; Wherein, Bit [0] position is set to " 1 ", and expression input and output pin GPIO0 is set to the GPIO pattern, and bit [1] position is set to " 1 "; Expression is arranged to the GPIO pattern to input and output pin GPIO1, and the like.
Configure generic purpose enable register, enable pass is with the status information position of input and output pin.When general input and output pin GPIO0～GPIO15 only is configured to input pattern, could receive the variation of outside level signal, responding system control is interrupted.The bit [31:16] of general purpose enable register GPE0_EN (General Purpose Event0 Enables Register) is used for enabling the status information position of GPIO0～GPIO15, so that corresponding general input and output pin can generation system control interrupt event.Wherein, bit [16] enable pass is with the status information position GPI0_STS of input and output pin GPIO0, and bit [17] enable pass is with the status information position GPI1_STS of input and output pin GPIO1, and the like.
Configure generic input and output mask register becomes input pattern with general input and output pin configuration.Correctly receiving system control interruption when general input and output pin GPIO0～GPIO15 only is configured to input pin; Therefore need the bit [15:0] of general input and output mask register GP_IO_SEL (GPIO Input/OutputSelect Register) be carried out the configuration of input pin function, be used to receive outside level signal.Wherein, bit [0] position is set to " 1 ", and expression is arranged to input pin to general input and output pin GPIO0, is used for receiving system control look-at-me; " 1 " is arranged in bit [1] position, and expression is arranged to input pin to general input and output pin GPIO1, is used for receiving system control look-at-me, and the like.
After configuring above-mentioned each register, the general input and output pin that is connected with button can be controlled look-at-me in receiving system under the operating system, and can correct responding system control interrupt.After system's control interruption generating; The ACPI that operating system can be called under the OSPM drives a method removing to carry out institute's response events; The disposal route of this incident need define in Basic Input or Output System (BIOS) (BIOS) code, and bios code a plurality of incidents that control is interrupted according to the generation system come to define respectively the disposal route of a plurality of response events.Among the present invention, the disposal route of system's control interrupt event is output and button corresponding identifier.
In step S100; When certain or certain the several buttons in a plurality of buttons are pressed; Because button links to each other with general input and output pin GPIO0～GPIO15 on hardware circuit; GPIO pin (being among the GPIO0～GPIO15) level that the button that is pressed will cause being connected with this button changes, thereby the control of generation system is interrupted.
In step S200, have no progeny in the control of generation system, the ACPI that operating system can be called under the OSPM drives the method for removing to carry out response events, and this method is the output key corresponding identifier.Output identification symbol 0x55 after for example first button is pressed, output identification symbol 0xAA after second button is pressed, output identification accorded with 0xCC after the 3rd button was pressed, and the like.
In one embodiment, the output key corresponding identifier is the port output key corresponding identifier to appointment.Preferably, the port of said appointment is the 0x80 port.Can certainly be other IO (input and output) port, so long as the operable port of user gets final product.When a plurality of buttons were pressed, each button corresponding identifier all can output to the 0x80 port, and the port that obtains these identifiers can be same 0x80 port, also can be that the pairing different identification symbol of a plurality of buttons outputs to different IO ports respectively.
In another embodiment, the output key corresponding identifier is that the button corresponding identifier is outputed in the storer.Storer can be Electrically Erasable Read Only Memory (Electrically ErasableProgrammable Read-Only Memory, EEPROM) or flash memory (Flash).
In step S300, the general application services program reads the port of appointment or the identifier in the storer, calls corresponding application program according to identifier.
When identifier outputs to the port (like the 0x80 port) of appointment; Read the identifier of this designated port through application services; The system's control that is produced is interrupted and can be distinguished through the identifier that obtains the 0x80 port because different key is pressed, and therefore can after application services defines different key through the identifier of judging the 0x80 port, call different application programs.For example; If the identifier of 0x80 port is 0x55; Then application services calls antivirus software, if the identifier of 0x80 port is 0xaa, then in application services, calls software upgrade procedure; If the identifier of 0x80 port is 0xCC, then in application services, call data sync program or the like.
In one embodiment; The process of output key corresponding identifier can also be through I2C bus (Inter-Integrated Circuit in BIOS in step S200; Be a kind of twin wire universal serial bus, be used for connecting microcontroller and peripherals thereof) different identifiers is outputed to EEPROM, then in step S300; Under operating system, read identifier through the EEPROM on the visit I2C bus, judgement is that which button has triggered system's control interruption.
In another embodiment; The process of output key corresponding identifier can also be through spi bus (Serial Peripheral Interface in BIOS in step S200; Serial peripheral equipment interface bus; A kind of synchronous serial interface is used for central processing unit and carries out full duplex, synchronous serial communication with various peripherals) different identifiers is outputed to Flash, then in step S300; Under operating system, read identifier through the Flash on the visit spi bus, judgement is that which button has triggered system's control interruption.
Because the embodiment of the invention is interrupted discrimination method for the user provides unified system's control; Know that which button is pressed and the system that triggered controls interruption; Make things convenient for the user to call different application programs at application services, and can be through the corresponding relation of application services change, increase or deletion button and application program.In addition, because the embodiment of the invention is only paid close attention to application services, need not pay close attention to the BIOS firmware code; Need not be solidificated in the function of application program among the BIOS; Do not had the restriction of BIOS chip space, can realize multiple function, particularly some complicated functions.
In addition, can change, increase or delete the pairing application program of each button through application services, need not because of button the corresponding application program of calling change and change the BIOS firmware code time and again, simple to operation.
In one embodiment, when button was pressed, application services prompting user selected corresponding application, confirmed the function of button by the user, was applicable to that available GPIO pin seldom realizes the situation that a plurality of application programs are fast called again.In addition, can also not provide unified judgement interface to the user, but directly in ACPI drives responding system control interrupt, notify the user invokes application.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
