This option 57 will generate CRCs of all blocks of memory, and store them before 58 going to sleep. The blocks are then checked on resume for any 59 errors. 60 61 Note, this can take several seconds depending on memory size 62 and CPU speed. 63 64 See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt> 65 66config S3C2410_PM_CHECK_CHUNKSIZE 67 int "S3C2410 PM Suspend CRC Chunksize (KiB)" 68 depends on ARCH_S3C2410 && PM && S3C2410_PM_CHECK 69 default 64 70 help 71 Set the chunksize in Kilobytes of the CRC for checking memory 72 corruption over suspend and resume.
