- This option adds support for using cryptoapi hashing

- This option adds support for using cryptoapi compression

- more than double your suspend and resume speed (depending

- default y
- ---help---
- This option enabled support for a userspace based user interface
- to TuxOnIce, which allows you to have a nice display while suspending
- and resuming, and also enables features such as pressing escape to
- cancel a cycle or interactive debugging.

- depends on TOI_CORE
- ---help---
- This entry allows you to specify a default image size limit. 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.

- 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"

-
- 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"

-
- 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. If your debugging output
- always says no pages were resaved, you may be able to safely disable this
- option.
