mx 25 linux power management issue with Xfbdev -keybd
We are facing linux power management failures .Our h/w and s/w details are
ARM -------- i.mx25
LTIB -------- L2.6.35-11-01-00_ER
Linux kernel -------- Linux - 2.6.31
Cross compiler ------- arm-none-linux-gnueabi-*(version-.4.4)
We make the LTIB for Gnome desktop environment.For normal follow it was working fine.
But when we are using the Power management (echo mem > /sys/power/state) our device going to sleep.
But after wakeup 'Xfbdev' not resuming properly.
Our Xfbdev cmd is
"Xfbdev -mouse tslib,2,device=/dev/input/ts0 -keybd keyboard,,device=/dev/input/event0"
What we observe that, when we pass "-keybd keyboard,,device=/dev/input/event0" to Xfbdev resuming fails
(This event0 is device specific keyboard event ).
We checked linux standardised usb keyboard driver along with lenovo usb keyboard ,but same issue appears.
Note : If we kill the Xfbdev and run once again its working normally.If we again going to Power management Xfbdev resuming fails.
Thanks and regards,
