Hi Sangmin,

We found that this message is not a kernel panic but a warning message
It is printed by the following code

syna-release/linux_4_9_q/drivers/soc/berlin/modules/rogue/src/pvr_counting_timeline.c
188 /* This is just a safety measurement. Normally we should never see any
189 * unsignaled sw fences when we come here. Warn if we still do! */
190 WARN_ON(!list_empty(&timeline->active_fences));

We also tried v19.524.15 which also prints this warning message.

Hi Sangmin,

Is there a problem with the screencap function?
Because I can use screencap normally.
I think it's just a warning message and has been printed since the original version.
We have not modified the related code.

Thank you.
Dean

Hi, Dean,

If this is a just warning message, is it possible to remove it?

(SW) Dean Chiang

Hi Sangmin,

Yes. It can be removed.
Do you want to remove it?

Thank you.

Hi, Dean,

Are you going to remove the below line?

    /* This is just a safety measurement. Normally we should never see any
     * unsignaled sw fences when we come here. Warn if we still do! */
    WARN_ON(!list_empty(&timeline->active_fences));

I'm worried that there is any other side effect in case of removing warning messages.
Could you please let me know why this warning messages are printed?

Thank you.

Hi Sangmin,

The Code is from Synaptics and seems to the synchronization mechanism.
Maybe we can confirm with Synaptics.

Thank you.

Hi, Dean,

Please ask to Synaptics.

Thank you.

I got the message from Synaptics as follows,

The meaning is "When PVR(graphic driver) close the Fence(SYNC), resource doesn't exist."
As now, this is not critical bug.

Close this issue.
