tegra x1 opencl support

#1

Has anyone tried to get opencl working on the x1 (or k1)? I’m trying to get the libfreenect2 running on the tegra using the OpenCL DepthPacketProcessor, but when I run Protonect example it errors out with:

cl::Platform::get failed: -1001

I installed clinfo to debug why openCL isn’t working and it cannot find any platforms.
$clinfo
I: ICD loader reports no usable platforms

I can’t find the icd files for the tegra (http://wiki.tiker.net/OpenCLHowTo).

Sorry, OpenCL driver is not supported for Tegra.
Can you use opengl_depth_packet_processor from libfreenect2?

Alternatively, it would be straightforward to port opencl_depth_packet_processor to CUDA.
Kernel code is nearly the same between CUDA & OpenCL, and CPU-side driver code is significantly condensed with CUDA.

#3

I realize this is an old topic but could NVIDIA guys please let us know if OpenCL is going to be supported on TX1 at all? I’m sure a great chunk of market where TX1 would fit very well is missed because of lacking OpenCL libraries.

#4

Well, I’ve got an official feedback from NVIDIA that there are no plans to support OpenCL on TX1 at the moment.

#5

So, Do you kown what should we do to use the TX1 with libfreenect2 to get the depth image?

#6

OpenCL is not a requirement for libfreenect2. Please see:

#7

sorry, i just knew this today, and i wonder if it a requirement for the iai_kinect2? I have run the iai_kinect2 package and have no problem i can see, i’m confused as many people said the opencl is not suport the tx1, where reflect?

#8

There is a version of iai_kinect which works with the Jetson. See:

See Step 14: Install IAI_KINECT2 for details.
