Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

ROCm Is AMD's #1 Priority, Executive Says
Its not that they're supporting buggy code, they just downgraded the quality of their implementation significantly. They made the compiler a lot worse when they swapped to rocm
https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime/iss... is the tracking issue for it filed a year ago, which appears to be wontfix largely because its a lot of work
OpenCL still unfortunately supports quite a few things that vulkan doesn't, which makes swapping away very difficult for some use cases

rocm-opencl (rocm-opencl-runtime) rx 6600 xt support
There's https://docs.amd.com/bundle/ROCm-Installation_FAQ/page/Frequently_Asked_Questions.html which leads to a page which doesn't list any gpus that I can see, there's https://rocm.docs.amd.com/en/latest/release/gpu_os_support.html which lists "RDNA2" , there's https://github.com/RadeonOpenCompute/ROCm/issues/1698 which is from last year and mentions changing an env for the RX 6600 XT (navi 23) . Not a lot is mentioned in the readme of https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime .

First time in 2 years I was able to get Blender running with an AMD GPU on Linux!
Eg this bug about shared cl/gl textures with mipmaps being broken has now breached its first birthday, without even acknowledgement - basic cl/gl functionality here. This bug took a year for a fix to make its way into a public driver. And this fairly performance critical bug is just "wontfix", and also a significant downgrade from their old driver stack
-
So far I'm unconvinced a 34MB binary blob is more free than OpenZFS.
Its definitely workable if you're willing to put in the effort (except for things that are straight up broken in some cases, like device side enqueue), but there are some issues that require.. fairly major workarounds

C++ Show and Tell - April 2022
After a lot of moderately annoyed testing, I discovered that the AMD OpenCL implementation is.. rather dumb. If any two kernels share any arguments arguments, it inserts a command barrier between the two, hard-stalling the GPU. After filing a bug, it turns out this is wontfix as well, which is doubly bad. There's no set of flags in OpenCL that you can use to fix this either

[TPU] AMD ROCm 4.5 Drops "Polaris" Architecture Support
What's particularly bizarre, is that with one bug report I filed, they claim to have fixed it internally in april, but.. no public driver has ever been released with the fix. For 7 months? Which is just a bizarre software development process

Who is to blame for the bad OpenCL Performance? Blender or AMD?
Could you report these issues here https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime? Regarding the device side enqueue issue, could you attach a simple test case to the issue that reproduces the crash? The current pastebin link doesn't give enough info.
