Then, upon reboot, one could add 610 the boot command line "verbose_mcheck=1" to get the normal 611 verbose machine check printing, or "verbose_mcheck=2" to get 612 the maximum information available. 613 614 Take the default (1) unless you want more control or more info. 615 616config HZ 617 int 618 default 1200 if ALPHA_RAWHIDE 619 default 1024 620 621source "drivers/pci/Kconfig" 622source "drivers/eisa/Kconfig" 623 624source "drivers/pcmcia/Kconfig" 625 626config SRM_ENV 627 tristate "SRM environment through procfs" 628 depends on PROC_FS 629 ---help--- 630 If you enable this option, a subdirectory inside /proc called 631 /proc/srm_environment will give you access to the all important 632 SRM environment variables (those which have a name) and also 633 to all others (by their internal number). 634 635 SRM is something like a BIOS for Alpha machines. There are some 636 other such BIOSes, like AlphaBIOS, which this driver cannot 637 support (hey, that's not SRM!). 638 639 Despite the fact that this driver doesn't work on all Alphas (but 640 only on those which have SRM as their firmware), it's save to 641 build it even if your particular machine doesn't know about SRM 642 (or if you intend to compile a generic kernel). It will simply 643 not create those subdirectory in /proc (and give you some warning, 644 of course). 645 646 This driver is also available as a module and will be called 647 srm_env then. 648 649source "fs/Kconfig.binfmt" 650 651endmenu 652 653source "net/Kconfig" 654 655source "drivers/Kconfig" 656 657source "fs/Kconfig" 658 659source "arch/alpha/Kconfig.debug" 660 661# DUMMY_CONSOLE may be defined in drivers/video/console/Kconfig 662# but we also need it if VGA_HOSE is set 663config DUMMY_CONSOLE 664 bool 665 depends on VGA_HOSE 666 default y 667 668source "security/Kconfig" 669 670source "crypto/Kconfig" 671 672source "lib/Kconfig" 673 674
