SK-AM62-LP: 3D cube runs at low fps

Hi Wilson,

cat /sys/kernel/debug/pvr/status

should give the status of GPU when you are running Kmscube application.

Suren

Hi, Suren,

Thanks for quick response. The command returns

root@am62pxx-evm:~# cat /sys/kernel/debug/pvr/status
cat: can't open '/sys/kernel/debug/pvr/status': No such file or directory

Look like we have to enable debug and rebuild rootfs. Is there a way to enable debug?

Best Regards,

Wilson

Looks the IMG rogue driver module is not inserted.

Can you share the output of lsmod command?

Best regards,

Suren

Hi, Suren,

There was no module listed, if booted from OSPI.

Hi Wilson,

Happy New Year!

The graphics libraries and binaries are present in the Filesystem. You need to insert the module before running the application. 

In the init script you would see that I had inserted the pvrsrv.ko module using insmod before running the Kmscube application.

Hope this helps!

Best Regards,

Suren

Hi, Suren,

Happy New Year!!

Boot from SD and find out the path of pvrsrvkm.ko (/lib/modules/6.6.44-ti-01478-g541c20281af7-dirty/updates/pvrsrvkm.ko) <-- built by yocto.

Then, boot from OSPI, run insmod, then system reports Invalid module format.

Our SDK is 10.0.0.14, and its linux kernel version is 6.6.32. Should we move to 10.1.0.33? Just checked that kernel version in SDK 10.1.0.33 is 6.6.58, not 6.6.44.

Or we should modify PV version to "6.6.32+git" in the linux-ti-staging_6.6.bb in yocto? If so, please suggest SRCREV.

Thanks,

Wilson Hung
