AP_POWER_STATE_REQ in Vehicle HAL

vinothkumars — Tue, 28 Apr 2020 04:51:18 GMT

Hi All,

I am working in Android Automotive with IMX8QM-MEK.

Tested with dumsys (dumpsys activity service com.android.car inject-vhal-event 0x11410a00 4,2). Upon executing the above command Board and display suspend for a few seconds (2-3 secs) and resumes. When the system is suspended terminal cannot be used to communicate.

My expectation is after the system resumes, it should be restored to previous configuration. Suppose the system goes to sleep when I was in Settings, after it wakes up it should open with settings screen. In this case launches with default screen.
From second time onward the touch control doesn't work after the system resumes.
Also sometimes after the system resumes, it isn't showing default CAN parameters ( Gear = P, HVAC = ON , Temp.=66 )

Reference: Power Management | Android Open Source Project

Thanks & Regards,

Vinoth S,

Hi Vinoth

one can look in Android P9.0.0_2.1.1_Auto Documentation

to check what is supported for power control.

In particular Release Notes Table 2. Features :

Power - CPU Freq, Power - Bus Freq

and Table 12. SRTM AUTO Control in Android_User's_Guide.pdf

Best regards
igor
