Hi! I'm working with a STM32MP157c-eval board. I found out that in the Starter Package image the etnaviv module is blacklisted. Isn't it the GPU driver? Why is the galcore module loaded as out-of-tree module instead?

[Lmoio.1]

Moreover, when I play the demo video, core usage reaches up to 70%, so is the GPU really working?

The blacklist file:

root@stm32mp1:~# cat /etc/modprobe.d/blacklist.conf
 blacklist etnaviv

Dmesg:

root@stm32mp1:~# dmesg | grep galcore
[   19.326759] galcore: loading out-of-tree module taints kernel.

Lsmod:

root@stm32mp1:~# lsmod | grep galcore
galcore               319488  6

Core usage while playing video:

10:56:40     CPU    %usr   %nice    %sys %iowait    %irq   %soft  %steal  %guest  %gnice   %idle

Hello,

Concerning your question related to STM32MP157c - ST is allowed to deliver only the Firmware/Driver from GPU Provider .

Hello,

sorry I don't understand how this is related to my question...

Hi @Lmoio.1​ ,

Galcore is the only GPU driver allowed to be delivered by Vivante on MP1 platform.

GPU is not used during video decode use case which is 100% handle by main CPU.

GPU is only used for graphic operation such as flip, resize, filter ...

Hi @Community member​ ,

so what's the difference between galcore.ko and etnaviv.ko?

Thanks
