gpu hang

Postby bk_chuang » Tue Feb 14, 2017 2:16 am


we are poring latest wandboard-android-6 bsp on our imx6-dl board
when doing run-in test over days by our test app
(show color patterns to check display, play audio and adjust vol to check audio, just switch tests between activities)
it randomly encounters a problem that app/screen is frozen (touch is no response) about 5 mins, and then go back to home screen
check with logs, will see errors, like "gpu fence timeout..., gpu hang, automatic recovery..." (details in attachment)
seriously, the device reboots directly without msgs
do you have any idea about it?!

and we found there are two versions of gpu driver (3.14.52 (default), 3.14.26) in kernel(3.14.52)
but 3.14.26 driver is not compatible to gpu hal libraries (device/fsl-proprietary/gpu-viv)
do you have libraries for gpu-3.14.26-driver

thx in advance
