Is OpenCL 1.2 Supported on i.MX6?

Hi All,

We are using the i.MX6 and we need to use openCL 1.2, is this version supported?

I was looking on the documentation [1] and section 5 (page 40) says that the Vivante GPU/FW only supports openCL 1.1 at the moment the document was written (2015). Is this still the case?

Regards,

-David

My understanding is that the GPU core is limited to OpenCL 1.1 Embedded Profile (not event Full).

the latest version 4.9.11 Upgraded GPU to 6.2.2.p0, which should support OpeCL 1.2

Your answer only applies to i.mx6 Dual/Quad Plus (i.MX6QP, i.MX6DP) soc types. As per the i.MX_Graphics_User's_Guide documentation (L4.9.11_1.0.0) :

OpenCL 1.1 Embedded Profile is applicable to GC2000 Vivante GPU core.
OpenCL 1.2 Full Profile is only applicable to GC2000+, GC7000XSVX & GC7000L Vivante GPU cores.

the GPU driver is for 6SABRE-SD,6SABRE-AI,6SoloX,6SoloLite,7ULP,8QuadMax,8MQuad, not only for imx6QP and IMX6DP

Hi Joan, Does this means that a regular i.MX6 Quad (no plus) could use the new drivers and get openCL 1.2 up and running?

yes, I think so

Interesting, because my understanding from the documentation is that this is more a hardware limitation on the GPU version available in the regular quad and not in the GPU driver only.

I checked it again, yes, you're right, imx6qp can support it, but imx6q couldn't support opencl1.2 on hardware.
