435 config SAMSUNG_PM_DEBUG
436 bool "S3C2410 PM Suspend debug"
440 Say Y here if you want verbose debugging from the PM Suspend and
441 Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
442 for more information.
444 config S3C_PM_DEBUG_LED_SMDK
445 bool "SMDK LED suspend/resume debugging"
446 depends on PM && (MACH_SMDK6410)
448 Say Y here to enable the use of the SMDK LEDs on the baseboard
449 for debugging of the state of the suspend and resume process.
451 Note, this currently only works for S3C64XX based SMDK boards.
453 config SAMSUNG_PM_CHECK
454 bool "S3C2410 PM Suspend Memory CRC"
455 depends on PM && CRC32
457 Enable the PM code's memory area checksum over sleep. This option
458 will generate CRCs of all blocks of memory, and store them before
459 going to sleep. The blocks are then checked on resume for any
462 Note, this can take several seconds depending on memory size
465 See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
467 config SAMSUNG_PM_CHECK_CHUNKSIZE

469 depends on PM && SAMSUNG_PM_CHECK
472 Set the chunksize in Kilobytes of the CRC for checking memory
473 corruption over suspend and resume. A smaller value will mean that
474 the CRC data block will take more memory, but wil identify any
475 faults with better precision.
