Change to HIP and OCL in ROCm 5.7

["Jeremy Newton" <alexjnewt@fastmail.com>]

Hi,

As a big FYI, I've been informed that OpenCL and HIP will be changing in ROCm to put all the sources in one tree, since there's a lot of source code overlap between the two components. I believe I've already spoke about this with a few of the people here.

I'm told the change is scheduled for ROCm 5.7, and the development tree is ready if you want to try it out:

https://github.com/ROCm-Developer-Tools/clr

This new tree combines hipamd, opencl, and rocclr.

As far as I know ROCm 5.6 will be using the old separated trees.

As well, I believe the HIP tree is still needed to compile:

https://github.com/ROCm-Developer-Tools/hip

For Fedora, I'd like to work with upstream to separate HIP (as opposed to hipamd) to its own package, since I believe it aims to be vendor neutral, but that's a very low priority for me, since Fedora doesn't even have ROCm HIP yet.

Feel free to reach out if you have any issues. I don't monitor the debian-ai list very closely, so please remember to CC me if you respond to this.

Thanks
