Map BUG power button to Android power button #10

Closed kgilmer closed 13 years ago

kgilmer commented 13 years ago

Currently (as of build 47) the power button causes no change on an Android-booted BUG.

kgilmer commented 13 years ago

I had played around with enabling the TWL4030 power button but wasn't able to get it working. Kernel panics on boot saying that the button could not be registered twice.

kgilmer commented 13 years ago

After some more digging I've found that the power button is enabled via TWL4030 code in 2.6.32 that varies greatly from 2.6.31 BL kernel. Enabling the option in the defconfig naturally causes a conflict. It's unclear if the pre-existing button configuration yet works, but it is present here:

/sys/devices/platform/twl4030_pwrbutton

teknosalsero commented 13 years ago

Yes, power button would be nice!

teknosalsero commented 13 years ago

This should also trigger sleep mode.

kgilmer commented 13 years ago

Suspend will be addressed as a separate issue as it's more complex than just shutdown.

Matt Isaac's commit https://github.com/buglabs/android-froyo-kernel/commit/7c887e04f1147df4713f728b61e1166b609e2e5f has enabled the power button. Now, when holding down the power button, a shutdown menu is provided allowing the user to shut the device down. After some time the screen goes blank but the backlight and LEDs are still on. Logcat provides the following clues:

kgilmer commented 13 years ago

I tried commenting out the stanza generating the error in the omap3 framebuffer.cpp driver:

if (ioctl(m->framebuffer->fd, OMAPFB_WAITFORVSYNC, 0)) { LOGE("ioctl OMAPFB_WAITFORVSYNC failed!!\n"); //m->base.unlock(&m->base, buffer); return -errno; }

This results in different log data but the same situation: LEDs and backlight are on, system says "halted" but still response to serial console. Logcat contents:

kgilmer commented 13 years ago

As of build 89 this feature works thanks to Matt's kernel fixes.

bcruskie commented 13 years ago

I confirmed the following functionality of the power button in build 89:

Press and release: lockscreen Press and hold for 1 second: Phone options menu displays, user can select Power off to shutdown

teknosalsero commented 13 years ago

I confirmed too. How awesome!
