Problem on Nexus 7 (2nd gen) with Adreno 320

Our application (Unity 3D game) always crashes on Nexus 7(2nd Generation) in random places with the absolutely same reason after some minutes of normal work (see log):

W/Adreno200-GSL(19088): <gsl_ldd_control:397>: ioctl fd 36 code 0x400c0907 (IOCTL_KGSL_DEVICE_WAITTIMESTAMP_CTXTID) failed: errno 35 Resource deadlock would occur

I/ActivityManager( 526): Process com.**.****.********** (pid 19088) has died.

Crash log is always the same, except the number after words "ioctl fd" (it may be 36, 39, 40, etc).

We thought that this might have something to do with the GPU (Adreno 320) in the 2nd gen Nexus 7, but other Adreno 320 (Galaxy S4, Nexus 4) appear to be working fine.

Can you provide any hint for us or at least explain this log? Which reason can be possible for this crash?

Sorry to hear that you're experiencing a crash on the Nexus 7.

Would you be able to provide us with an apk that we can use to duplicate the problem here?

thanks..

I'm not sure of the status of this particular issue, but the issues mentioned in the blog have all been fixed, and updated binary drivers for Nexus devices will be posted here within the next couple of weeks.

Is there any more information on this issue, we have a similar problem with our game closing (no program has stopped mesage - just boom and gone, sometimes it even hard resets the device).  The main device we have tested on that cause the problem is a 2013 edition of the nexus 7.  I have tracked through the code and it seems to be related to VAO usage, given how it dies im at a loss as to how to best track this issue.

 

Any advice would be great, we are ment to be shipping shortly, i can just disable the VAO but dont really want to have to do this

Any information on the text that Dave said that development drivers will be coming to nexus devices? It has been much longer than a couple of weeks at this point.

The intention was to push out an update on December 18th, but there were performance regressions that manifested at the last minute that delayed the release. Due to the holidays, many key people have been out, so I'm not sure of the current status, but there IS someone currently dedicated to supporting development drivers now, so there will an update soon.

Can we have an eta for us Nexus users? we've had this problem 3 months now since 4.4, just clarify has this been fixed with the v66 drivers or will us Nexus users be getting something newer than Samsung's & Asus's last updates?

The currently posted driver *might* support Nexus 7, but it hasn't been tested on it. There is an upcoming release (probably next week) that will be tested on Nexus 7, though.

The current Nexus 5 release unfortunately doesn't support Nexus 7, but the Nexus 7 release is scheduled to be out by the end of this month.

I tried installing UPDATE-adreno-drivers-razor.zip via K0T49H 4.4.2r1 stock system recovery and I get the following

Finding update package
Opening update package
E: footer is wrong
E:signature verfication failed
Installation aborted.

I shouldn't have to unlock the bootloader to install a custom recovery just to apply a driver update, Not when signed driver's are offered by google

Unfortunately, we are not able to sign our driver updates with Google's platform key. That's why a recovery image that's willing to install unsigned update packages is required. Although these releases are for developers, they are meant to be installed without the need for an AOSP source tree.
