Then, upon reboot, one could add 613 the boot command line "verbose_mcheck=1" to get the normal 614 verbose machine check printing, or "verbose_mcheck=2" to get 615 the maximum information available. 616 617 Take the default (1) unless you want more control or more info. 618 619config HZ 620 int 621 default 1200 if ALPHA_RAWHIDE 622 default 1024 623 624source "drivers/pci/Kconfig" 625source "drivers/eisa/Kconfig" 626 627source "drivers/pcmcia/Kconfig" 628 629config SRM_ENV 630 tristate "SRM environment through procfs" 631 depends on PROC_FS 632 ---help--- 633 If you enable this option, a subdirectory inside /proc called 634 /proc/srm_environment will give you access to the all important 635 SRM environment variables (those which have a name) and also 636 to all others (by their internal number). 637 638 SRM is something like a BIOS for Alpha machines. There are some 639 other such BIOSes, like AlphaBIOS, which this driver cannot 640 support (hey, that's not SRM!). 641 642 Despite the fact that this driver doesn't work on all Alphas (but 643 only on those which have SRM as their firmware), it's save to 644 build it even if your particular machine doesn't know about SRM 645 (or if you intend to compile a generic kernel). It will simply 646 not create those subdirectory in /proc (and give you some warning, 647 of course). 648 649 This driver is also available as a module and will be called 650 srm_env then. 651 652source "fs/Kconfig.binfmt" 653 654endmenu 655 656source "net/Kconfig" 657 658source "drivers/Kconfig" 659 660source "fs/Kconfig" 661 662source "arch/alpha/Kconfig.debug" 663 664# DUMMY_CONSOLE may be defined in drivers/video/console/Kconfig 665# but we also need it if VGA_HOSE is set 666config DUMMY_CONSOLE 667 bool 668 depends on VGA_HOSE 669 default y 670 671source "security/Kconfig" 672 673source "crypto/Kconfig" 674 675source "lib/Kconfig" 676 677
