Pages are compressed using the zlib library, with a default + setting (in code) of fastest compression (still VERY slow!). If your swap + device is painfully slow compared to your CPU, you might possibly want + this.

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 /proc/software_suspend 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 writer), 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! + + comment 'Debugging' + + config SOFTWARE_SUSPEND_DEBUG + bool ' Compile in debugging output' + ---help--- + This option enables the inclusion of debugging info in the software + suspend code.
