Then, upon reboot, one could add 611 the boot command line "verbose_mcheck=1" to get the normal 612 verbose machine check printing, or "verbose_mcheck=2" to get 613 the maximum information available. 614 615 Take the default (1) unless you want more control or more info. 616 617config HZ 618 int 619 default 1200 if ALPHA_RAWHIDE 620 default 1024 621 622source "drivers/pci/Kconfig" 623source "drivers/eisa/Kconfig" 624 625source "drivers/pcmcia/Kconfig" 626 627config SRM_ENV 628 tristate "SRM environment through procfs" 629 depends on PROC_FS 630 ---help--- 631 If you enable this option, a subdirectory inside /proc called 632 /proc/srm_environment will give you access to the all important 633 SRM environment variables (those which have a name) and also 634 to all others (by their internal number). 635 636 SRM is something like a BIOS for Alpha machines. There are some 637 other such BIOSes, like AlphaBIOS, which this driver cannot 638 support (hey, that's not SRM!). 639 640 Despite the fact that this driver doesn't work on all Alphas (but 641 only on those which have SRM as their firmware), it's save to 642 build it even if your particular machine doesn't know about SRM 643 (or if you intend to compile a generic kernel). It will simply 644 not create those subdirectory in /proc (and give you some warning, 645 of course). 646 647 This driver is also available as a module and will be called 648 srm_env then. 649 650source "fs/Kconfig.binfmt" 651 652endmenu 653 654source "net/Kconfig" 655 656source "drivers/Kconfig" 657 658source "fs/Kconfig" 659 660source "arch/alpha/Kconfig.debug" 661 662# DUMMY_CONSOLE may be defined in drivers/video/console/Kconfig 663# but we also need it if VGA_HOSE is set 664config DUMMY_CONSOLE 665 bool 666 depends on VGA_HOSE 667 default y 668 669source "security/Kconfig" 670 671source "crypto/Kconfig" 672 673source "lib/Kconfig" 674 675
