Rendering image uses the ethnaviv driver but I want to use the galcore driver for rendering

[ravicalm]

Rendering image uses the ethnaviv driver but I want to use the galcore driver for rendering . could you please tell me how to disable the ethnaviv and enable the galcore driver for the imx7ulp board.

Note: please don't tell follow this document / that document please give the exact info and file information where we need to modify.

@Sanket_Parekh  In imx7ulp cef(chromium embed framework launching process is taking so much 100% cpu) do u know how to shift the load from cpu to gpu?

Hi @Sanket_Parekh ,
is it possible to have microsoft teams call with you?

[Sanket_Parekh]

Hi @ravicalm 

I hope you are doing well.

i.MX gpu tests only support galcore driver.

However , one can look for below tools for etnaviv gpu driver.

Etnaviv GPU tests

Hi @Sanket_Parekh,
with the above ethnaviv gpu tests I am not able to see how much gpu is using while rendering the images that is why I asked you to how to disable ethnaviv and enable galcore but If I try to use the galcore device tree node the device is not booting up could you please share the kernel source code where there is an enable of galcore?
one doubt: is imx7ulp supports galcore?? because in my code they have given support to ethnaviv

[Sanket_Parekh]

Hi @ravicalm 

I hope you are doing well.

does imx7ulp supports galcore?? because in my code they have given support to ethnaviv.

[Ans] : Yes , i.MX7ULP supports galcore.

           In older kernel versions it uses etanviv.

the kernel source for the galcore driver is at /drivers/mxc/gpu-viv.

It can be enabled using the below option and gpu device tree node.

CONFIG_MXC_GPU_VIV=y

Thanks & Regards,

Hi @Sanket_Parekh, If I introduce this tree node and the configuration in my code the device is not booting up

[Sanket_Parekh]

Hi @ravicalm 

I hope you are doing well.

Please share the device boot failing logs and changes made to the linux kernel config and dts for further debugging.

Thanks & Regards,

Hi @Sanket,
I need a call with you sharing logs and sharing configuration and boot logs against company policy we will have call tell me the process which I can follow to have a call with you

Hi @ravicalm,

I hope you are doing well.

It is not possible for me to have a call with you.

Please connect with NXP Professional Services for on-call debugging.

I have the following info

Operating System: Poky (Yocto Project Reference Distro) 2.7.1 (warrior)

I will share the by deivce tree file info.

Hi @Sanket_Parekh 

I hope I have given enough info could you please and update with your findings

[Sanket_Parekh]

Hi @ravicalm ,

I hope you are doing well.

The device tree node for gpu doesn't seem correct in your attached .dtsi file.

Please refer to and change the gpu: gpu@41800000 node under imx7ulp.dtsi file.

Please add the below option in the kernel configuration.

CONFIG_MXC_GPU_VIV=y

Please also mention which document you followed to set up yocto.

As it seems you are not using the yocto provided by NXP.

I hope it helps!

Thanks & Regards,

@ Sanket_Parekh is it possible to have a call ?

Hi @Sanket_Parekh  I have posted my question clearly based on the dmesg logs rendering images uses ethnaviv driver not galcore . so I need to check the performance of gpu we have gpu tool and gpuinfo.sh scrpit based on galcore . So I want to enable galcore driver instead of ethnaiv driver.

could you help me share the device tree and configuration wrt the galcore 

[Sanket_Parekh]

Hi @ravicalm 

I hope you are doing well.

i.MX BSP by default uses a galcore driver.

Please look at https://github.com/nxp-imx/linux-imx/tree/lf-6.1.y/drivers/mxc/gpu-viv

linux-imx/drivers/mxc/gpu-viv/hal/os/linux/kernel/platform/Freescale/gc_hal_kernel_platform_imx.c

It seems that you are not using i.MX BSP.

For the device tree, Please look at gpu node in /arch/arm/boot/dts/imx7ulp.dtsi

Please provide me with your source link of the BSP used & also the BSP version.

Thanks & Regards,

Sanket Parekh

[Sanket_Parekh]

Hi @ravicalm 

I hope you are doing well.

I.MX BSP uses galcore GPU driver by default available at /drivers/mxc/gpu-viv.

Additionally one can add the below line in local.conf

IMAGE_INSTALL += " kernel-module-imx-gpu-viv "

Thanks & Regards,

@Sanket_Parekh my final agenda is to check the gpu performance (how much percentage of gpu was used while rendering the images) if the rendering uses the ethnaviv driver may I know is there any tool which can check the gpu performance if gpu uses the ethanviv driver?
