System hangs when execute google-chrome

Hi All,

We are running Yocto L3.10.53-1.1.2_patch with wayland backend on our customized board.

We sometimes get errors when we use google-chrome.

The system sometimes hangs or only console is alive.

The console.log is dumped from console when system hangs.

The chrome_debug.log is the log that we find in chrome dir when system hangs but console is alive.

BSP: Yocto L3.10.53-1.1.2_patch with wayland backend

CPU: i.MX6Q 1.2 GHZ

RAM: 1GB

Chrome version: 40.0.2214.91

I'd appreciate any advice to solve this problem. Thanks.

HI Wei-Fong

from console.log:

"1.2G chip, increase VDDARM_IN/VDDSOC_IN

Read SW1AB error!

....

pfuze100-regulator 1-0008: unrecognized pfuze chip ID!

pfuze100-regulator: probe of 1-0008 failed with error -5 "

seems you are not using pmic mmpf0100 or use ldo-bypass mode.

For 1.2GHz chip one needs to use only ldo enable option

(from i.MX_Linux_Release_Notes.pdf):

Best regards

igor

Hi igorpadykov,

Thanks for apply.

I trace the source code of chrome. I find it shows gpu out of memory error.

Then I add "--gpu-program-cache-size-kb=5242880" parameter when I start chrome.

It makes situation better.

So, my questions are

1. How do I know the current gpu memory usage ?

2. How do I increase the reserved gpu memory ?

Many Thanks,

Frank
