PVR Tune issue (driver support not found)


Hi, I’m tring to profile an application on my LG L9 (sgx540) with android ice cream sandwich.

But PVRPerfServer says:

"Failed to initialise services connection (driver support not found)"

How can I enable it on my device?

I have root permissions so I can also change drivers.


Hi David,

To support GPU profiling, the drivers have to be built with profiling enabled. It seems that the ones on your device do not support it.

To enable profiling, you would have to install drivers that have been built with this support. LG may be able to help you with this, but I can’t say for certain.
