If you say Y here, the system time will be 663 reset after a RESUME operation, the /proc/apm device will provide 664 battery status information, and user-space programs will receive 665 notification of APM "events" (e.g. battery status change). 666 667 In order to use APM, you will need supporting software. For location 668 and more information, read <file:Documentation/pm.txt> and the 669 Battery Powered Linux mini-HOWTO, available from 670 <http://www.tldp.org/docs.html#howto>. 671 672 This driver does not spin down disk drives (see the hdparm(8) 673 manpage ("man 8 hdparm") for that), and it doesn't turn off 674 VESA-compliant "green" monitors. 675 676 Generally, if you don't have a battery in your machine, there isn't 677 much point in using this driver and you should say N. If you get 678 random kernel OOPSes or reboots that don't seem to be related to 679 anything, try disabling/enabling this option (or disabling/enabling 680 APM in your BIOS). 681 682endmenu 683 684source "net/Kconfig" 685 686menu "Device Drivers" 687 688source "drivers/base/Kconfig" 689 690source "drivers/connector/Kconfig" 691 692if ALIGNMENT_TRAP 693source "drivers/mtd/Kconfig" 694endif 695 696source "drivers/parport/Kconfig" 697 698source "drivers/pnp/Kconfig" 699 700source "drivers/block/Kconfig" 701 702source "drivers/acorn/block/Kconfig" 703 704if PCMCIA || ARCH_CLPS7500 || ARCH_IOP3XX || ARCH_IXP4XX \ 705 || ARCH_L7200 || ARCH_LH7A40X || ARCH_PXA || ARCH_RPC \ 706 || ARCH_S3C2410 || ARCH_SA1100 || ARCH_SHARK || FOOTBRIDGE 707source "drivers/ide/Kconfig" 708endif 709 710source "drivers/scsi/Kconfig" 711 712source "drivers/md/Kconfig" 713 714source "drivers/message/fusion/Kconfig" 715 716source "drivers/ieee1394/Kconfig" 717 718source "drivers/message/i2o/Kconfig" 719 720source "drivers/net/Kconfig" 721 722source "drivers/isdn/Kconfig" 723 724# input before char - char/joystick depends on it.
