Standby option not available under /sys/power/state

[B_K_Ankur]

Hello Friends,

I am using kernel 3.10.32 on imx28evk board. Please find the attached config file with the post. Even I have selected CONFIG_SUSPEND is selected, there is no standby option under /sys/power/state.

Command:

root@imx28evk:~# cat  /sys/power/state

freeze mem

Snipp of config file:

CONFIG_SUSPEND=y

CONFIG_SUSPEND_FREEZER=y

CONFIG_PM_SLEEP=y

# CONFIG_PM_AUTOSLEEP is not set

CONFIG_PM_WAKELOCKS=y

CONFIG_PM_WAKELOCKS_LIMIT=100

CONFIG_PM_WAKELOCKS_GC=y

CONFIG_PM_RUNTIME=y

CONFIG_PM=y

CONFIG_PM_DEBUG=y

CONFIG_PM_ADVANCED_DEBUG=y

# CONFIG_PM_TEST_SUSPEND is not set

# CONFIG_APM_EMULATION is not set

CONFIG_PM_CLK=y

CONFIG_CPU_PM=y

CONFIG_ARCH_SUSPEND_POSSIBLE=y

CONFIG_ARM_CPU_SUSPEND=y

Can anyone please give me some hint or clue what I am missing in the config file to enable the standby mode?

Regards,

Ankur

Thank you Fabio,

Could you please share your thoughts:

1) What to do to enable the support (where I can start) for Standby for Kernel version 3.10.32?

2) Which latest kernel supports Standby Mode for imx28?

Regards,

Ankur
