i.MX6DQ GPU stops.

Hi community,

Our partner met a GPU problem with the following log on a i.MX6DQ android_jb4.2.2_1.1.0-ga based custom board..

<4>[galcore]: Can't dump when GPU is power off or clock off.

Would you let me know the condition to output the above log?

Only when GPU power or clock is gating as indicated the log?

Or is it output when GPU is hang up also?

Best Regards,

Satoshi Shimoda

Hi Igor,

Thank you for your reply.

I think the patch is for L3.10.17_1.0.0-ga or later.

Then, I found same code in android_jb4.2.2_1.1.0-ga (kernel = L3.0.35_4.1.0) as below.

So the following codes should be inserted after line 5727 in this case.

gckOS_Delay(gcvNULL, gcdPOWEROFF_TIMEOUT);

if (Hardware->chipPowerState != gcvPOWER_ON

&& Hardware->chipPowerState != gcvPOWER_IDLE

)

{

gcmkPRINT("[galcore]: Can't dump when GPU is power off or clock off.");

gcmkFOOTER_NO();

return gcvSTATUS_OK;

}

Best Regards,
