PVRPerfServerDeveloper does not detect GPU on Synaptics Astra SoC

Hi sinseok,

Can you please make sure the PowerVR GPU driver is running?

Try with the commands below:
sudo -SE /etc/init.d/rc.pvr stop
sudo -SE /etc/init.d/rc.pvr start

Also please verify what is the output of:
udevadm trigger --verbose --dry-run | grep drm

Best regards,
Alejandro
