Enabling GPU (Vivante) for Ls1028A in Yocto

[AOS2025]

Hi everyone,

I am trying to enable Vivante GPU support on the LS1028A for OpenCL and GPU acceleration. According to the NXP Semiconductors LS1028ARDB-PA Datasheet, the driver is referred to as: MXC Vivante GPU Support

I have tried :Searching in menuconfig:  When I search (/) for: MXC_GPU_VIV , It shows up in the results, but it is not selectable.Trying to navigate to its supposed location:
→Device Drivers 

 → MXC support drivers 

   → MXC Vivante GPU Support

it is not there.
I have also checked the dependancies of the MXC_GPU_VIV mentioned in menuconfig:
Depends on: ARCH_MXC && DRM , DRM is enabled, but ARCH_MXC is not.
I Searched for ARCH_MXC: Symbol: ARCH_MXC [=ARCH_MXC] - Type: unknown

 Symbol: ARCH_MXC_ARM64 [=ARCH_MXC_ARM64] - Type: unknown 

I cannot find any option to enable ARCH_MXC.
The manual for LS1028A specifically mentions "MXC Vivante GPU support," which is confusing because it seems locked behind ARCH_MXC.

Is there a way to enable MXC Vivante GPU Support on LS1028A if it is locked behind ARCH_MXC?

Should I be enabling etnaviv instead? (I see it in menuconfig, but I am not sure if this is equivalent to the "MXC Vivante GPU Support" mentioned in the manual).
Do I need to patch the Device Tree (DTS) to activate GPU support?
Is there another Kconfig setting I am missing that unlocks ARCH_MXC for Layerscape platforms?

Which Yocto are required to add OpenCL and gpu support Vivante GPUs on the LS1028A?

I tried adding: IMAGE_INSTALL:append = " imx-gpu-viv opencl gpu-viv-bin-imx"

However, I am not sure if this is enough or even correct since Ls1028 is not in the imx family.

Any help would be appreciated

Hello

Yocto has by default enable the GPU for LS1028A just build the bitbake ls-image-desktop on the 6.11.10 BSP

Hello,
Thank you for your previous suggestion to use ls-image-desktop for GPU support on ls1028a. I attempted to follow your instructions but encountered several issues:

When building ls-image-desktop, I received the following error:

ERROR: Nothing RPROVIDES 'ubuntu-base' (but /home/o/Project/yocto/sources/meta-nxp-desktop/recipes-fsl/images/ls-image-desktop.bb RDEPENDS on or otherwise requires it)

ubuntu-base was skipped: incompatible with machine ls1028ardb (not in COMPATIBLE_MACHINE)

I modified ls-image-desktop.bb to remove the Ubuntu dependencies and use core-image-minimal, but there were still more errorsr:

ERROR: Nothing RPROVIDES 'systemd-gpuconfig'

systemd-gpuconfig was skipped: 'systemd' not in DISTRO_FEATURES

I added systemd to DISTRO_FEATURES, but then it began to conflict with the layers from meta-nxp-desktop.

Additionally, the Langdale branch is outdated and not fully supported anymore, so I had to manually copy files into layers and update them to get past certain errors.
This is turning into a long chain of compatibility issues. I am simply trying to enable OpenCL and GPU support for headless data processing on the ls1028a, without a full desktop environment.

Hello!

LS1028A may not support MXC Vivante GPU directly since ARCH_MXC is tied to i.MX platforms. Instead, using Etnaviv might be better. Try modifying the DTS for GPU recognition and adjusting Yocto configurations for proper OpenCL and GPU support.
