It can - be overridden at run-time using /sys/power/tuxonice/image_size_limit. - - config TOI_KEEP_IMAGE - bool "Allow Keep Image Mode" - depends on TOI_CORE - ---help--- - This option allows you to keep and image and reuse it. It is intended - __ONLY__ for use with systems where all filesystems are mounted read- - only (kiosks, for example). To use it, compile this option in and boot - normally. Set the KEEP_IMAGE flag in /sys/power/tuxonice and suspend. - When you resume, the image will not be removed. You will be unable to turn - off swap partitions (assuming you are using the swap allocator), but future - suspends simply do a power-down. The image can be updated using the - kernel command line parameter suspend_act= to turn off the keep image - bit. Keep image mode is a little less user friendly on purpose - it - should not be used without thought! - - config TOI_INCREMENTAL - bool "Incremental Image Support" - depends on TOI_CORE && 64BIT && TOI_KEEP_IMAGE - default n - ---help--- - This option enables the work in progress toward using the dirty page - tracking to record changes to pages. It is hoped that - this will be an initial step toward implementing storing just - the differences between consecutive images, which will - increase the amount of storage needed for the image, but also - increase the speed at which writing an image occurs and - reduce the wear and tear on drives. - - At the moment, all that is implemented is the first step of keeping - an existing image and then comparing it to the contents in memory - (by setting /sys/power/tuxonice/verify_image to 1 and triggering a - (fake) resume) to see what the page change tracking should find to be - different. If you have verify_image set to 1, TuxOnIce will automatically - invalidate the old image when you next try to hibernate, so there's no - greater chance of disk corruption than normal. - - comment "No incremental image support available without Keep Image support." - depends on TOI_CORE && !TOI_KEEP_IMAGE && 64BIT - - config TOI_REPLACE_SWSUSP - bool "Replace swsusp by default" - default y - depends on TOI_CORE - ---help--- - TuxOnIce can replace swsusp. This option makes that the default state, - requiring you to echo 0 > /sys/power/tuxonice/replace_swsusp if you want - to use the vanilla kernel functionality. Note that your initrd/ramfs will - need to do this before trying to resume, too. - With overriding swsusp enabled, echoing disk to /sys/power/state will - start a TuxOnIce cycle. If resume= doesn't specify an allocator and both - the swap and file allocators are compiled in, the swap allocator will be - used by default. - - config TOI_IGNORE_LATE_INITCALL - bool "Wait for initrd/ramfs to run, by default" - default n - depends on TOI_CORE - ---help--- - When booting, TuxOnIce can check for an image and start to resume prior - to any initrd/ramfs running (via a late initcall). - - If you don't have an initrd/ramfs, this is what you want to happen - - otherwise you won't be able to safely resume. You should set this option - to 'No'. - - If, however, you want your initrd/ramfs to run anyway before resuming, - you need to tell TuxOnIce to ignore that earlier opportunity to resume. - This can be done either by using this compile time option, or by - overriding this option with the boot-time parameter toi_initramfs_resume_only=1. - - Note that if TuxOnIce can't resume at the earlier opportunity, the - value of this option won't matter - the initramfs/initrd (if any) will - run anyway. - - menuconfig TOI_CLUSTER - bool "Cluster support" - default n - depends on TOI_CORE && NET && BROKEN - ---help--- - Support for linking multiple machines in a cluster so that they suspend - and resume together. - - config TOI_DEFAULT_CLUSTER_INTERFACE - string "Default cluster interface" - depends on TOI_CLUSTER - ---help--- - The default interface on which to communicate with other nodes in - the cluster. - - If no value is set here, cluster support will be disabled by default. - - config TOI_DEFAULT_CLUSTER_KEY - string "Default cluster key" - default "Default" - depends on TOI_CLUSTER - ---help--- - The default key used by this node. All nodes in the same cluster - have the same key. Multiple clusters may coexist on the same lan - by using different values for this key. - - config TOI_CLUSTER_IMAGE_TIMEOUT - int "Timeout when checking for image" - default 15 - depends on TOI_CLUSTER - ---help--- - Timeout (seconds) before continuing to boot when waiting to see - whether other nodes might have an image. Set to -1 to wait - indefinitely. In WAIT_UNTIL_NODES is non zero, we might continue - booting sooner than this timeout. - - config TOI_CLUSTER_WAIT_UNTIL_NODES - int "Nodes without image before continuing" - default 0 - depends on TOI_CLUSTER - ---help--- - When booting and no image is found, we wait to see if other nodes - have an image before continuing to boot. This value lets us - continue after seeing a certain number of nodes without an image, - instead of continuing to wait for the timeout. Set to 0 to only - use the timeout. - - config TOI_DEFAULT_CLUSTER_PRE_HIBERNATE - string "Default pre-hibernate script" - depends on TOI_CLUSTER - ---help--- - The default script to be called when starting to hibernate. - - config TOI_DEFAULT_CLUSTER_POST_HIBERNATE - string "Default post-hibernate script" - depends on TOI_CLUSTER - ---help--- - The default script to be called after resuming from hibernation. - - config TOI_DEFAULT_WAIT - int "Default waiting time for emergency boot messages" - default "25" - range -1 32768 - depends on TOI_CORE - help - TuxOnIce can display warnings very early in the process of resuming, - if (for example) it appears that you have booted a kernel that doesn't - match an image on disk. It can then give you the opportunity to either - continue booting that kernel, or reboot the machine. This option can be - used to control how long to wait in such circumstances. -1 means wait - forever. 0 means don't wait at all (do the default action, which will - generally be to continue booting and remove the image). Values of 1 or - more indicate a number of seconds (up to 255) to wait before doing the - default. - - config TOI_DEFAULT_EXTRA_PAGES_ALLOWANCE - int "Default extra pages allowance" - default "2000" - range 500 32768 - depends on TOI_CORE - help - This value controls the default for the allowance TuxOnIce makes for - drivers to allocate extra memory during the atomic copy. The default - value of 2000 will be okay in most cases. If you are using - DRI, the easiest way to find what value to use is to try to hibernate - and look at how many pages were actually needed in the sysfs entry - /sys/power/tuxonice/debug_info (first number on the last line), adding - a little extra because the value is not always the same. - - config TOI_CHECKSUM - bool "Checksum pageset2" - default n - depends on TOI_CORE - select CRYPTO - select CRYPTO_ALGAPI - select CRYPTO_MD4 - ---help--- - Adds support for checksumming pageset2 pages, to ensure you really get an - atomic copy. Since some filesystems (XFS especially) change metadata even - when there's no other activity, we need this to check for pages that have - been changed while we were saving the page cache.
