PVRPerfServerDeveloper does not detect GPU on Synaptics Astra SoC

Hello

PVRPerfServerDeveloper is not recognizing the GPU.

I’m trying to measure performance using PVRTune, so I launched PVRPerfServerDeveloper. However, it fails to detect the GPU.

I’m using a Synaptics Astra board with a PowerVR Rogue GE9920 GPU.

Here is the console output:

Do I need to install any additional GPU drivers or take further steps to make the GPU visible to PVRPerfServerDeveloper?

I haven’t had any issues using the GPU with OpenCL — it seems to work fine in that context.

Thank you

Hi sinseok,

Thanks for your email, and welcome to the PowerVR Developer Forum!

Can you please show the result of the command below?
sudo cat /sys/kernel/debug/pvr/version

This will show the PowerVR GPU driver version you have installed.

Best regards,
Alejandro

The current GPU driver version is as follows

root@sl1680:/home/sinseok# cat /sys/kernel/debug/pvr/version

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

Hello,

The file /etc/init.d/rc.pvr does not exist.

Also, the result of the command udevadm trigger --verbose --dry-run | grep drm is as follows:

root@sl1680:/home/sinseok# udevadm trigger --verbose --dry-run | grep drm
/sys/devices/platform/soc/f7980000.gpu/drm/card1
/sys/devices/platform/soc/f7980000.gpu/drm/renderD128
/sys/devices/platform/soc/soc:drm
/sys/devices/platform/soc/soc:drm/drm/card0
/sys/devices/platform/soc/soc:drm/drm/card0/card0-DSI-1
/sys/devices/platform/soc/soc:drm/drm/card0/card0-HDMI-A-1

Could it be that the driver is not supported?

Thank you.

Hi sinseok,

Thanks for providing the information requested.

The fact that the file /etc/init.d/rc.pvr does not exist points in the direction that you do not have any GPU driver installed.

I would check with the board manufacturer for possible ways to obtain / build that driver.

Best regards,
Alejandro
