Surfaceflinger Error. #51

Closed Pratiksha0102 closed 5 months ago

I'm encountering the same error you might have seen earlier related to SurfaceFlinger. My system is running kernel version 5.10 for Android 12 on an rk3399 board.

For your reference, I've attached the log file here: android_log.txt

Surfaceflinger is essential for rendering the display, and I'm unable to resolve the issue despite searching various resources. Could you please guide me on how to troubleshoot this error?

Thanks in advance for your help.

Hi everyone,

I'm glad to report that I've found a solution for the SurfaceFlinger.

The problem:

The user encountered an error related to SurfaceFlinger, a critical system process responsible for managing the device's display. This error prevented the Android system from starting properly, resulting in only the u-boot logo being displayed.

Diagnosis:

By analyzing the system logs using adb shell logs, we were able to pinpoint the root cause of the problem.

The solution:

The problem stemmed from missing kernel configurations for the ION memory allocator. ION plays a vital role in shared memory functionality, which is essential for SurfaceFlinger to operate correctly.

Here's how I resolved the issue:

Enable kernel configurations:

CONFIG_ION=y CONFIG_ION_SYSTEM_HEAP=y CONFIG_ION_SYSTEM_CONTIG_HEAP=y

Enabling these configurations allows the system to utilize ION and create the necessary /dev/ion device for shared memory.

Verification:

After enabling the configurations, the SurfaceFlinger error was successfully resolved. The display is now functioning as expected.
