The development of the EDVAC computer system of 1948 is often cited as the beginning of the computer era. Since that time, computer systems have evolved into extremely complicated devices. Today's computers are much more sophisticated than early systems such as the EDVAC. Computer systems typically include a combination of hardware and software components, application programs, operating systems, processors, buses, memory, input/output devices, and so on. As advances in semiconductor processing and computer architecture push the performance of the computer higher and higher, more sophisticated computer software has evolved to take advantage of the higher performance of the hardware, resulting in computer systems today that are much more powerful than just a few years ago.
As computer software advances, hardware requirements for executing such computer software also advance. Increased hardware requirements typically include increased power consumption in computer systems. Consider computer gaming software as one example type of computer software for which hardware requirements and associated power consumption have increased greatly in the recent past. High power consuming graphics adapters capable of meeting graphics processing requirements of computer gaming software continue to consume larger amounts of power than an integrated graphics adapter, or other low-power graphics adapter, even when the computer system is not executing graphics- intensive computer gaming software. Such power consumption during idle, or nearly idle, periods of time, is inefficient and wasteful when alternative, low-power consuming graphic adapters, such as an integrated graphics adapter of a computer motherboard are available in most, if not all, computer systems.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Exemplary methods, apparatus, and products for dynamically managing power consumption of a computer in accordance with the present invention are described with reference to the accompanying drawings, beginning with Figure 1. Figure 1 sets forth a block diagram of an exemplary system for dynamically managing power consumption of a computer (152) according to embodiments of the present invention. The computer (152) of Figure 1 includes at least one computer processor (156) or 'CPU' as well as random access memory (168) ('RAM') which is connected through a high speed memory bus (166) and bus adapter (158) to processor (156) and to other components of the computer (152).
Stored in RAM (168) is an application (126), a module of computer program instructions that carries out user-level data processing tasks. Examples of such applications (126) include video games, spreadsheet applications, work processors, multimedia players, web browsers, and so on as will occur to readers of skill in the art. Also stored in RAM (168) is an operating system (154). Operating systems useful for dynamically managing power consumption of a computer according to embodiments of the present invention include UNIX™, Linux™, Microsoft XP™, AIX™, IBM's i5/OS™, and others as will occur to those of skill in the art.
The operating system (154) in the example of Figure 1 includes a graphics driver (102), a module of computer program instructions that enables higher-level computer program applications to interact with the graphics adapters (207, 209). In addition to enabling higher- level computer program applications to interact with the graphics adapters (207, 209), the graphics driver (102) in the example of Figure 1 also operates generally for dynamic power consumption management of the computer (152). Although the graphics driver (102) in the example of Figure 1 is depicted as a software component of the operating system, readers of skill in the art will recognize that graphics drivers configured for dynamic power consumption management of a computer according to embodiments of the present invention may also be standalone modules of computer program instructions separate from an operating system. The operating system (154), graphics driver (102), and application (126), in the example of Figure 1 are shown in RAM (168), but many components of such software typically are stored in non-volatile memory also, such as, for example, on a disk drive (170).
The example computer (152) of Figure 1 also includes one or more input/output ('I/O') adapters (178). I/O adapters implement user-oriented input/output through, for example, software drivers and computer hardware for controlling output to display devices such as computer display screens, as well as user (101) input from user input devices (181) such as keyboards and mice. The example computer (152) of Figure 1 includes two graphics adapters (207, 209), which are examples of I/O adapters specially designed for graphic output to a display device (180) such as a display screen or computer monitor. Graphics adapters (207, 209) are connected to processor (156) through a high speed video bus (164), bus adapter (158), and the front side bus (162), which is also a high speed bus. The example computer (152) is configured with a number of graphics adapter configurations (104). Each graphics adapter configuration (104) identifies one or more of the graphics adapters (207, 209) to activate and use for graphics processing in particular graphics processing-related circumstances, referred to in this specification as predefined graphics processing criteria (106). The predefined graphics processing criteria (106) in the example of Figure 1 is a data structure including an association of graphics loads (105) and graphics adapter configurations (104). A graphics load (105) is a metric of graphics processing operation or consumption, such as frame rates, graphics quality settings, or in some embodiments, particular user applications each of which may consume a different amount of graphics processing during execution. The predefined graphics processing criteria (106) in the example of Figure 1 specifies a particular graphics adapter configuration (104) for each different graphics load (105).
The graphics driver (102), as mentioned above, in addition to enabling higher- level computer program applications to interact with the graphics adapters (207, 209) also operates generally for dynamic power management of the computer (152) in the example of Figure 1. The graphics driver is said to manage power consumption 'dynamically' in that the graphics driver manages power consumption of the computer automatically, without human intervention, during operation of the computer. The graphics driver (102) may manage power consumption in the computer (152) by: monitoring operation of a current graphics adapter configuration (104), the monitored operation characterized by a graphics processing load (110); determining, in dependence upon the graphics processing load (110) of the current graphics adapter configuration (104), whether operation of the current graphics adapter configuration (104) conforms to predefined graphics processing criteria (106); if operation of the current graphics adapter configuration (104) conforms to the predefined graphics processing criteria (106), processing graphics for display with the one or more graphics adapters of the current graphics adapter configuration (104); and if operation of the current graphics adapter configuration (104) does not conform to the predefined graphics processing criteria (106), processing graphics for display with the one or more graphics adapters (207, 209) of another graphics adapter configuration (104). In some computers for which power consumption is dynamically managed by a graphics adapter according to embodiments of the present invention, the graphics adapters (207, 209) include a graphics adapter integrated with the computer's main motherboard and a graphics adapter installed as a hardware component, a video card, in an expansion slot of the computer, such as Peripheral Component Interconnect ('PCF) slot or an Accelerated
Graphics Port ('AGP') slot. Such integrated graphics adapters typically consume less power than a non- integrated, expansion graphics adapter. The graphics driver (102) then may manage power consumption in such a computer by processing graphics with the low-power consuming integrated graphics adapter when under a low graphics processing load and with the expansion graphics adapter when under a high graphics processing load. That is, the graphics driver manages power, reduces power consumption, by processing graphics with lower-power graphics adapter configurations when the computer is operating under a lower graphics processing load. In other computers in which power consumption is managed by the graphics according to embodiments of the present invention, the graphics adapters installed in the computer (152) may include, in addition to an integrated graphics adapter, a multi-Graphics Processing Unit ('GPU') graphics adapter, such as an ATI Technologies Crossfire graphics card or an nVidia Scalable Link Interface ('SLF) graphics card, where each GPU of the graphics card is capable of operating as an individual graphics adapter. That is, each graphics card includes multiple graphics adapters. In such computers in which such multi-GPU graphics card are installed, each GPU may be capable of consuming an equal amount of power. As such, the graphics driver may manage power consumption, reducing such power consumption, by processing graphics with fewer than all GPUs or only the integrated graphics adapter when the computer is operating under a low graphics processing load.
The computer (152) of Figure 1 also includes flash memory (186) is connected through a high speed memory bus (166) and bus adapter (158) to processor (156). Stored in flash memory (186) is a Basic Input/Output Services ('BIOS') module (188), a module of computer program instructions, executed upon startup of the computer (152), that initializes system component hardware, through initial boot procedures, such as the graphics adapters
(207, 209), hard disk drives (170), and floppy disk drives, and some other hardware devices. Such initialization prepares the computer into a known low-capability state, so other software programs, such as the operating system (154), stored in computer memory may be loaded, executed, and given control of the computer. The BIOS module (188) in the example of Figure 1 may be configured such that upon startup and during initial boot procedures of the computer (152), the BIOS module (188) activates only a default graphics adapter configuration - a least power consuming graphics adapter of the computer (152). In most embodiments, the least power consuming graphics adapter (207, 209), the default graphics adapter, is the integrated graphics adapter, not an expansion adapter, as described above.
In computers of the prior art, the output of each separate graphics adapter installed in a computer enclosure is typically connected to a separate port. Outputs of separate graphics adapters installed in a computer enclosure of the prior art are typically not connected to the same input port of a computer display. In fact, a separate data communications cable typically connects each separate port to an input port on a separate display. That is, one display for each graphics adapter installed in a computer enclosure of the prior art. The outputs of the graphics adapters (207, 209) in the example computer (152) of Figure 1, however, are configured for connection to the same input port of a computer display (180). In the example computer (152) of Figure 1 for which power consumption is managed, the outputs of the two or more graphics adapters (207, 209) are connected, inside a computer enclosure, depicted in Figure 1 by the dashed-line square enclosing the computer (152) components, to a same output port of the computer, the output port connecting the computer to a computer display. That is, the outputs of the graphics adapters are connected within the computer enclosure, and instead of having multiple separate output ports on a computer enclosure, the computer (152) of Figure 1 is configured with only one output port.
The exemplary computer (152) of Figure 1 also includes disk drive adapter (172) coupled through expansion bus (160) and bus adapter (158) to processor (156) and other components of the computer (152). Disk drive adapter (172) connects non-volatile data storage to the computer (152) in the form of disk drive (170). Disk drive adapters useful in computers for dynamically managing power consumption of a computer according to embodiments of the present invention include Integrated Drive Electronics ('IDE') adapters, Small Computer System Interface ('SCSI') adapters, and others as will occur to those of skill in the art. Non- volatile computer memory also may be implemented for as an optical disk drive, electrically erasable programmable read-only memory (so-called 'EEPROM' or 'Flash' memory), RAM drives, and so on, as will occur to those of skill in the art.
The exemplary computer (152) of Figure 1 also includes a communications adapter (167) for data communications with other computers (182) and for data communications with a data communications network (100). Such data communications may be carried out serially through RS-232 connections, through external buses such as a Universal Serial Bus ('USB'), through data communications data communications networks such as IP data communications networks, and in other ways as will occur to those of skill in the art.
Communications adapters implement the hardware level of data communications through which one computer sends data communications to another computer, directly or through a data communications network. Examples of communications adapters useful in systems that dynamically manage power consumption of a computer according to embodiments of the present invention include modems for wired dial-up communications, Ethernet (IEEE 802.3) adapters for wired data communications network communications, and 802.11 adapters for wireless data communications network communications.
The arrangement of servers and other devices making up the exemplary system illustrated in Figure 1 are for explanation, not for limitation. Data processing systems useful according to various embodiments of the present invention may include additional servers, routers, other devices, and peer-to-peer architectures, not shown in Figure 1, as will occur to those of skill in the art. Networks in such data processing systems may support many data communications protocols, including for example TCP (Transmission Control Protocol), IP (Internet Protocol), HTTP (HyperText Transfer Protocol), WAP (Wireless Access Protocol),
HDTP (Handheld Device Transport Protocol), and others as will occur to those of skill in the art. Various embodiments of the present invention may be implemented on a variety of hardware platforms in addition to those illustrated in Figure 1.
As mentioned above, in computers of the prior art, the output of each separate graphics adapter installed in a computer enclosure is typically connected to a separate port. In computers for which power consumption is managed dynamically by a graphics driver according to embodiments of the present invention, the outputs of graphics adapters may be configured differently. For further explanation, therefore, Figure 2 sets forth a block diagram depicting an exemplary system in which power consumption of a computer is dynamically managed according to embodiments of the present invention. The system of Figure 2 includes a computer, enclosed in a computer enclosure (214) and a computer display (180). Installed in the computer enclosure (214) in the example system of Figure 2 are two graphics adapters similar to those depicted in the example system of Figure 1. The outputs of the two or more graphics adapters, represented in Figure 2 by graphics adapter ports (212), are connected, external to the computer enclosure (214), to the same input port (202) of the computer display (180). In this example, the each graphics adapter output port
(212) is connected by a data communications cable (206, 208) through an adapter (210) and another data communications cable (204) to one input port (202) of the computer display (180). In this way the graphics adapter may seamlessly, or near-seamlessly, alternate between processing graphics with the two graphics adapters. Furthermore, connecting the outputs of graphics adapters external to the computer enclosure enables implementation of dynamic power consumption management of a computer according to embodiments of the present invention with no need of hardware reconfiguration of currently configured computers and computer enclosures such as reconfiguration of motherboards Printed Circuit Board (TCB') layouts, internal bus ports, internal data communications cables, port availability of enclosures, and so as will occur to readers of skill in the art.
Readers of skill in the art will immediately recognize that connecting multiple graphics adapter outputs to a single computer display (180) input port (202) is just one way among many to connect outputs of multiple graphics adapters to a display of a computer for which power consumption is managed by a graphics driver according to embodiments of the present invention. Another example way in which outputs of multiple graphics adapters to a display of a computer for which power consumption is managed by a graphics driver according to embodiments of the present invention includes connecting the output of each graphics adapter to a separate input of computer display. Computer displays may include multiple input ports such as, for example, a Video Graphics Array ('VGA') port, a Digital
Visual Interface Port ('DVF) port, a DiplayLink™ Universal Serial Bus ('USB') port, and so on. For further explanation, Figure 3 sets forth a flow chart illustrating an exemplary method for dynamically managing power consumption of a computer according to embodiments of the present invention. The method of Figure 3 is carried out in a computer configured similar to the computer of Figure 1 above. Such a computer (152 on Figure 1) includes two or more graphics adapters (207, 209 on Figure 1) with each graphics adapter configured to process graphics for display on a computer display (180 on Figure 1). The computer (152 on Figure 1) is configured with a number of graphics adapter configurations (104) with each graphics adapter configuration (104) including one or more of the graphics adapters (207, 209 on Figure 1).
Upon startup and during initial boot procedures of the computer, the method of Figure 3 includes activating (314), by the BIOS module (316) of the computer, only a default graphics adapter configuration (301) including a least power consuming graphics adapter of the computer. Activating (314), by the BIOS module (316) of the computer, only a default graphics adapter configuration (301) including a least power consuming graphics adapter of the computer may be carried out by only initializing the graphics adapter integrated with the main motherboard of the computer.
The method of Figure 3 also includes monitoring (304), by a graphics driver (102), operation of a current graphics adapter configuration, the monitored operation characterized by a graphics processing load (110). Monitoring (304), by a graphics driver (102), operation of a current graphics adapter configuration, the monitored operation characterized by a graphics processing load (110) may be carried out in several ways including monitoring frame display buffers, measuring an amount of time to display each frame on a computer display, receiving changes in graphics quality settings, monitoring application program launches, receiving function calls from higher-level application programs through an API exposed by the graphics driver that indicate changes in graphics processing loads, and so on as will occur to readers of skill in the art.
The method of Figure 3 also includes determining (306), in dependence upon the graphics processing load (110) of the current graphics adapter configuration (302), whether operation of the current graphics adapter configuration conforms to predefined graphics processing criteria (106). In the method of Figure 3 the predefined graphics processing criteria (106) is depicted as a table having a column of graphics adapter configurations (104) and a column of graphics processing loads (312). Each graphics adapter configuration (104) in the example predefined graphics processing criteria (106) table is associated with a particular load (312). Determining (306) whether operation of the current graphics adapter configuration conforms to predefined graphics processing criteria (106) includes determining whether the load (110) of the current graphics processing conforms to the load (312) associated with the current configuration (302) in the predefined graphics processing criteria
(106).
If operation of the current graphics adapter configuration conforms to the predefined graphics processing criteria (106), the method of Figure 3 continues by processing graphics for display with the one or more graphics adapters of the current graphics adapter configuration (302). That is, the graphics driver makes no changes in graphics adapter operation. If operation of the current graphics adapter configuration (302) does not conform to the predefined graphics processing criteria (106), however, the method of Figure 3 continues by processing graphics for display with the one or more graphics adapters of another graphics adapter configuration (406). Processing graphics for display with the one or more graphics adapters of another graphics adapter configuration (406) includes identifying from the predefined graphics processing criteria (106) a graphics adapter configuration (406) that does in fact conform to the current graphics processing load (110) and activating the one or more graphics adapters of the configuration, by loading graphics adapter-specific graphics drivers.
For further explanation, Figure 4 sets forth a flow chart illustrating a further exemplary method for dynamically managing power consumption of a computer according to embodiments of the present invention. The method of Figure 4, like the method of Figure 3, is carried out in a computer configured similar to the computer of Figure 1 above. Such a computer (152 on Figure 1) includes two or more graphics adapters (207, 209 on Figure 1) with each graphics adapter configured to process graphics for display on a computer display
(180 on Figure 1). The computer (152 on Figure 1) is configured with a number of graphics adapter configurations (104) with each graphics adapter configuration (104) including one or more of the graphics adapters (207, 209 on Figure 1). The method of Figure 4 is also similar to the method of Figure 3 including as it does, the graphics driver's (102) monitoring (304) operation of a current graphics adapter configuration, the monitored operation characterized by a graphics processing load (110); determining (306), in dependence upon the graphics processing load (110) of the current graphics adapter configuration (302), whether operation of the current graphics adapter configuration conforms to predefined graphics processing criteria (106); if operation of the current graphics adapter configuration (302) conforms to the predefined graphics processing criteria (106), processing graphics for display with the one or more graphics adapters of the current graphics adapter configuration (302); and if operation of the current graphics adapter configuration (302) does not conform to the predefined graphics processing criteria (106), processing graphics for display with the one or more graphics adapters of another graphics adapter configuration (406). The method of Figure 4 differs from the method of Figure 3, however, in that in the method of Figure 4 monitoring (304) operation of a current graphics adapter configuration, the monitored operation characterized by a graphics processing load (110) includes monitoring (402) an instantaneous display frame rate (404) of the current graphics adapter configuration (304). In the method of Figure 4 determining (306) whether operation of the current graphics adapter configuration conforms to predefined graphics processing criteria (106) includes determining (410) whether the instantaneous display frame rate (404) of the current graphics adapter configuration (302) falls within a range of frame rates (408) specified by the predefined graphics processing criteria (106) for the current graphics adapter configuration (302).
For further explanation, Figure 5 sets forth a flow chart illustrating a further exemplary method for dynamically managing power consumption of a computer according to embodiments of the present invention. The method of Figure 5, like the method of Figure 3, is carried out in a computer configured similar to the computer of Figure 1 above. Such a computer (152 on Figure 1) includes two or more graphics adapters (207, 209 on Figure 1) with each graphics adapter configured to process graphics for display on a computer display (180 on Figure 1). The computer (152 on Figure 1) is configured with a number of graphics adapter configurations (104) with each graphics adapter configuration (104) including one or more of the graphics adapters (207, 209 on Figure 1). The method of Figure 5 is also similar to the method of Figure 3 including as it does, the graphics driver's (102) monitoring (304) operation of a current graphics adapter configuration, the monitored operation characterized by a graphics processing load (110); determining (306), in dependence upon the graphics processing load (110) of the current graphics adapter configuration (302), whether operation of the current graphics adapter configuration conforms to predefined graphics processing criteria (106); if operation of the current graphics adapter configuration (302) conforms to the predefined graphics processing criteria (106), processing graphics for display with the one or more graphics adapters of the current graphics adapter configuration (302); and if operation of the current graphics adapter configuration (302) does not conform to the predefined graphics processing criteria (106), processing graphics for display with the one or more graphics adapters of another graphics adapter configuration (406).
The method of Figure 5 differs from the method of Figure 3, however, in that in the method of Figure 5 monitoring (304) operation of a current graphics adapter configuration, the monitored operation characterized by a graphics processing load (110) includes detecting
(502) a launch of an application program. Detecting (502) a launch of an application program may be carried out in various ways including subscribing to an operating system provided notification module that sends notification upon each launch, through computer program code in the fork-exec system command to notify the graphics driver, and in other ways as may occur by readers of skill in the art. Detecting (502) a launch of an application program may also include identifying the application program, typically by application program name (504).
In the method of Figure 5 determining (306) whether operation of the current graphics adapter configuration conforms to predefined graphics processing criteria (106) includes identifying, in accordance with the predefined graphics processing criteria (106), a graphics adapter configuration (512) for the launched application program (508). Identifying a graphics adapter configuration (512) for the launched application program (508) may be carried out by finding in the predefined graphics processing criteria (106) a configuration (512) associated with the application name (504) of the launched application program. For further explanation, Figure 6 sets forth a flow chart illustrating a further exemplary method for dynamically managing power consumption of a computer according to embodiments of the present invention. The method of Figure 6, like the method of Figure 3, is carried out in a computer configured similar to the computer of Figure 1 above. Such a computer (152 on Figure 1) includes two or more graphics adapters (207, 209 on Figure 1) with each graphics adapter configured to process graphics for display on a computer display (180 on Figure 1). The computer (152 on Figure 1) is configured with a number of graphics adapter configurations (104) with each graphics adapter configuration (104) including one or more of the graphics adapters (207, 209 on Figure 1). The method of Figure 6 is also similar to the method of Figure 3 including as it does, the graphics driver's (102) monitoring (304) operation of a current graphics adapter configuration, the monitored operation characterized by a graphics processing load (110); determining (306), in dependence upon the graphics processing load (110) of the current graphics adapter configuration (302), whether operation of the current graphics adapter configuration conforms to predefined graphics processing criteria (106); if operation of the current graphics adapter configuration (302) conforms to the predefined graphics processing criteria (106), processing graphics for display with the one or more graphics adapters of the current graphics adapter configuration (302); and if operation of the current graphics adapter configuration (302) does not conform to the predefined graphics processing criteria (106), processing graphics for display with the one or more graphics adapters of another graphics adapter configuration (406).
The method of Figure 6 differs from the method of Figure 3, however, in that in the method of Figure 6 monitoring (304) operation of a current graphics adapter configuration, the monitored operation characterized by a graphics processing load (110) includes detecting (502) a system-wide change in graphics quality settings (604). Examples of types of graphics quality settings include anisotropic filtering, bilinear texture filtering, trilinear filtering, antialising, display resolution, video color settings, and so on as will occur to those of skill in the art.
In the method of Figure 6 determining (306) whether operation of the current graphics adapter configuration conforms to predefined graphics processing criteria (106) includes identifying (610), in accordance with the predefined graphics processing criteria (106), a graphics adapter configuration (612) for the changed system- wide graphics quality settings (604). The predefined graphics processing criteria (106) in the example of Figure 6 includes records associating a graphics adapter configuration (104) with a graphics processing load, in this case a graphics quality setting (508). Identifying (610) a graphics adapter configuration (612) for the changed system- wide graphics quality settings (604) then, may be carried out by finding in the predefined graphics processing criteria (106) a configuration associated with the changed system- wide graphics quality settings (604).
In view of the explanations set forth above, readers will recognize that the benefits of dynamically managing power consumption of a computer according to embodiments of the present invention include:
