OpenCL SoftISP demo works wrong on IMX8MP

[quercuspau]

Hello,

I am testing OpenCL capabilities on IMX8MP, currently im using the 8MPLUSLPD4-EVK evaluation board with BSP 5.10.72.

Tipping in the terminal from a pre-builded image:

The current bmp files look wrong, starting from 2-WhiteBalance.bmp. The current attachments are not the original files due the forum attachment limitation, but allow to see the overall problem.

0-SourceImage.png2-WhiteBalance.png3-Equalization.png4-RemoveNoise.png1-RemoveBadPixel.png

Is this a problem of the OpenCL implementation of the system or it is related to the demo itself?

The final goal is being able to codec RAW images in RGB format to jpeg using OpenCL.

i.mx8mp has HW ISP, why do you need softISP?

[quercuspau]

I am testing OpenCL on IMX8MP and NXP SoftISP demo doesn't work OK so Im wondering if OpenCL is well supported or demo has bugs.

[joanxie]

you can use softISP on OpenVX:

AFAIK, imx8mp doesn't support OpenVx.

•This hardware extension is available in the i.MX8MP NPU, which means that OpenVX hardware acceleration is performed on the NPU, not on the GPU
