Including at least the Nexus 4.

All we need to do is not activate this extension on these devices.

By the way, have you reported this to Qualcomm?

    
    

    
  
What was broken?  Is it fixed in the driver with 4.4?  Did we report it to Qualcomm?

    
    

    
  
Looks like I never mentioned what was broken. IIRC, it was dFdy always returning 0 on Adreno320. I don't believe this was reported to Qualcomm. What's the process for that?

    
    

    
  
Probably no need to -- sounds like it was fixed in newer drivers anyway at this point.
